OBJECTIVE: To culturally translate the cardiff acne disability index(CADI) into Korean, and to examine its relationship with clinical acne severity,pathological patterns, and general quality of life(Qo L).METHODS: The CADI was culturally and lin-guistically translated into Korean via translation,back-translation, and face validity test process. Two hundred and fifty-four Korean adolescents were asked to complete the Korean version of the CADI(K-CADI), the Phlegm Pattern, the Cold-Heat Pattern, and the Korean version of the General Health Questionnaires. A clinician estimated acne severity for the adolescents, using the Korean Acne Grading System. Finally, reliability and validity of the K-CADI was examined, and the relationships between acne severity, Phlegm, Cold, and Heat patterns, and Qo L level were examined via pathway ***: The K-CADI had satisfactory internal consistency(α = 0.827). The examination of construct validity indicated that the K-CADI had one factor(explaining 59.6% of the total variance). Pathway analysis showed satisfactory model fit(normal fit index = 0.960 and comparative fit index = 0.983),and acne-related Qo L was determinant to Phlegm,Heat, and Cold patterns(0.13-0.27 of β), and Phlegm and Heat patterns lowered one's Qo L level(0.17-0.34 of β).CONCLUSION: The K-CADI is a valid and reliable instrument. Phlegm and Heat patterns should be managed when treating acne since they have a moderating effect on general Qo L aggravation.

Optimal operation of microgrid using hybrid differential evolution and harmony search algorithm

引用

Frontiers in Energy 2016年第3期10卷 355-362页

作者： S. SURENDER REDDY jae young park Chan Mook JUNG Department of Railroad and Electrical Engineering Woosong University Republic of Korea Department of Railroad and Civil Engineering Woosong UniversityRepublic of Korea

This paper proposes the generation scheduling approach for a microgrid comprised of conventional generators, wind energy generators, solar photovoltaie （PV） systems, battery storage, and electric vehicles. The electrical vehicles （EVs） play two different roles： as load demands during charging, and as storage units to supply energy to remaining load demands in the MG when they are plugged into the microgrid （MG）. Wind and solar PV powers are intermittent in nature; hence by including the battery storage and EVs, the MG becomes more stable. Here, the total cost objective is minimized considering the cost of conventional generators, wind generators, solar PV systems and EVs. The proposed optimal scheduling problem is solved using the hybrid differential evolution and harmony search （hybrid DE-HS） algorithm including the wind energy generators and solar PV system along with the battery storage and EVs. Moreover, it requires the least investment.

We demonstrate the dipole-assisted carrier transport properties of bis(trifluoromethane)sulfonamide(TFSI)-treated O-ReS_(2) field-effect *** ReS_(2) was compared with defect-mediated ReS_(2) to confirm whether the presence of defects on the interface enhances the interaction between O-ReS_(2) and TFSI *** to the experiment,density functional theory(DFT)calculation was performed,and the result indicated that the charge transfer between TFSI and O-ReS_(2) is more sensitive to external electric fields than that between TFSI and pristine ReS_(2).After TFSI treatment,the drain current of O-ReS_(2) FET was significantly increased up to 1,113.4 times except in the range of−0.32–0.76 V owing to Schottky barrier modulation from dipole polarization of TFSI molecules,contrary to a significant degradation in device performance in pristine ReS_(2) ***,in the treated O-ReS_(2) device,the dipole direction was highly influenced by the voltage sweep direction,generating a significant area of hysteresis in I–V and transfer characteristics,which was further verified by the surface potential ***,the dipole state was enhanced according to the wavelength of the light source and *** results indicate that TFSI-treated ReS_(2) FET has large potential for use as next-generation memristor,memory,and photodetector.

Potentiation of apomorphine effect on sildenafil-induced penile erection in conscious rabbits

引用

Asian Journal of Andrology 2004年第3期6卷 205-209页

作者： jae-young park Hwancheol Son Soo Woong Kim jae-Seung Paick Department of Urology Seoul National University College of MedicineSeoulKoreaDepartment of UrologySeoul Municipal Boramae HospitalSeoulKoreaDepartment of UrologySeoul National University College of MedicineSeoulKoreaDepartment of UrologySeoul National University College of MedicineSeoulKorea

Aim: To investigate a possible potentiation effect of apomorphine (APO) on sildenafil-induced penile erection in the conscious rabbit. Methods: Erection of male New Zealand White rabbits (3.5-4.0 kg, n=12) was assessed by measuring the length of the uncovered penile mucosa and the duration of erection before and after intravenous administration of agents. After injection of APO (0, 0.05, 0.1 and 0.4 mg/kg), sildenafil was administered intravenously in a dose-response manner (0.5, 1 and 5 mg/kg). In additional experiments, the effect of increasing doses of sildenafil in combination with APO on systemic blood pressure was evaluated. Results: Systemic administration of sildenafil induced a dose-dependent increase in the penile length. Intravenous injection of APO alone did not produce any change in the penile length, while significantly enhanced the penile erection induced by sildenafil. The co-administration of 0.1 mg/kg of APO and 1 mg/kg of sildenafil was found to be the most effective combination in producing penile erection. Intravenous administration of sildenafil caused a concentration-dependent decrease in systemic blood pressure, but no additional decrease was observed with co-administration of APO. Conclusion: APO enhances the penile erection induced by sildenafil in the conscious rabbit without causing an additional decrease in blood pressure.

Relationships between Pathological Patterns and Vocal Qualities Estimated by Acoustic Parameters

引用

Chinese Journal of Integrative Medicine 2015年第5期21卷 346-354页

作者： young-jae park young-Bae park Department of Diagnosis and Biofunctional Medicine College of Korean MedicineKyung Hee University Department of Diagnosis and Biofunctional Medicine Kyung Hee University Hospital at Gangdong

Objective： To examine whether vocal characteristics estimated by acoustic parameters were associated with phlegm, yin deficiency, or cold-heat patterns. Methods： A total of 75 college students （males：females = 53：22） aged 19-24 years were enrolled in this study. Each subject was asked to complete the phlegm pattern questionnaire （PPQ）, yin deficiency questionnaire （YDQ） and cold-heat questionnaire （CHQ）. For the acoustic analysis, each subject was asked to produce a sustained vowel sound （/a/） for 3 s to be used to calculate acoustic parameters. Then, habitual fundamental frequency （F0）, jitter, shimmer, F0 tremor, mean F0, standard deviation of F0, maximum F0, minimum F0, normalized noise energy, harmonic-to-noise ratio, signal-to-noise ratio, amplitude tremor, and power ratio were calculated using the Dr. Speech software. Finally, four hierarchical regression models with pattern questionnaire scores as dependent variables were formed to examine which factors among acoustic parameters, sex, and age were predictive of those pattern scores. Results： PPQ, YDQ, heat, and cold pattern scores all formed significant regression model equations and the adjusted R2 values were 0.281, 0.164, 0.156, and 0.170, respectively. There were aging effects in the PPQ and YDQ models （standardized β =0.199, 0.271, respectively）. Vocal tremor-related Fo tremor and vocal ringing-related power ratio parameters were associated with PPQ and YDQ scores. Gender was directly predictive of PPQ and indirectly moderated the relationship between power ratio and YDQ score. Vocal pitch- related habitual F0 and mean F0 were associated with heat and cold scores. These results indicate that the vocal qualities of phlegm- and yin deficiency-susceptible subjects tend to be ringing and less tremorous, and those of heat- and cold-susceptible subjects tend to be high-pitched. Conclusion： Our study results suggest that vocal characteristics estimated by acoustic parameters are partially predictive of phlegm,

Microstructural Investigation of Alloy 617 Creep-ruptured at High Temperature in a Helium Environment

引用

Journal of Materials Science & Technology 2013年第12期29卷 1177-1183页

作者： Gyeong-Geun Lee Sujin Jung jae-young park Woo-Gon Kim Sung-Deok Hong Yong-Wan Kim Nuclear Materials Division Korea Atomic Energy Research Institute

A very high temperature reactor （VHTR） is one of the next-generation nuclear reactors chosen by the Generation IV International Forum. A Ni-base superalloy, Alloy 617, is considered as a primary candidate material for an intermediate heat exchanger （IHX） and hot gas duct （HGD） of the VHTR because of the superior creep resistance at a high temperature above 850 ~C. In this study, the microstructures of the specimens creep- ruptured at high temperatures in a helium environment were investigated. The decrease in rupture time was more pronounced with increasing creep temperature. In the specimens crept at 950 ~C, the external Cr-oxide layer of the specimens increased in thickness with increasing creep rupture time, and delaminated after a long-time creep. The high creep stress induced a deep penetration of carbide depletion along the grain boundaries at the early stage of the creep test. The creep temperature enhanced the growth rate of the decarburized zone depth clearly, but the temperature effect on the growth of the external oxide and internal oxide was not well understood as the surface reaction and creep stress affected the microstructures complexly.
