为深入探讨消费者对哺乳文胸款式的感性认知,基于网络数据获取哺乳文胸样本图,根据文胸哺乳口的打开方式将其划分为6类,采用分层抽样方法,最终得到11款哺乳文胸刺激图;从哺乳文胸的网络评论文本中,筛选出7对感性评价形容词;对18~40岁、有过哺乳经验的女性进行问卷调查,获取了其对不同款式哺乳文胸的感性评价;采用均值分析和因子分析对得到的感性评价进行量化,并运用TOPSIS模型对多种感性需求进行综合评价。结果表明,影响哺乳文胸感性评价的主要因子是外观和感官因素。消费者在面对哺乳文胸款式的多元化感性需求中,倾向于采用上开口式的哺乳口设计,整体杯面与下扒无装饰,并偏好波浪形设计的杯边或底围。决策综合评价方法有助于为多种感性需求提供个性化定制的参考。

Applying the wavelet theory and methods to investigate the hydrologic processes such as precipitation and runoff is a hot field. However, several aspects in research are usually ignored: the effect of admissible condition of wavelet functions and the disturbance of noises for the detection of periods, the effect of the length of a hydrologic time-series on the final result, and the choice between the anomaly and the original time series for wavelet analysis. In this paper, these issues are fully discussed. Precipitation data from Lanzhou Precipitation Station are taken for case study. The result indicates that in the wavelet analysis of hydrologic series, denoise methods should be used to eliminate the influence of noises. The MexHat wavelet function satisfies the admissible condition, which ensures that the periodic properties of hydrologic processes can be well represented by using the MexHat wavelet for decomposition. The affected range of hydro-logic series which should be discarded before analysis is given. It is also suggested that the anomaly series should be used to highlight the actual undulation of the hydrologic series.

AIM: To explore the association of serum insulin, insulin resistance, and β-cell dysfunction with gallstone disease (GSD) in type 2 diabetics. METHODS: We used a community-based study conducted between 1991 and 1993 in Kinmen, Taiwan to identify type 2 diabetics. A screening program for GSD was performed in 2001 by a panel of specialists who employed real-time ultrasound sonography to examine the abdominal region after the patient had fasted for at least 8 h. Screening was conducted in 2001 on 848 patients diagnosed with type 2 diabetes. The HOMA method was used to compare the profile differences for insulin resistance (HOMA IR) and β-cell dysfunction (HOMA β-cell). RESULTS: We studied 440 type 2 diabetics who attended sonography check-ups. After excluding eight insulin-treated diabetics, the prevalence of GSD among the remaining 432 was 13.9% (26/187) among males and 14.7% (36/245) among females. After adjustment for other GSD-associated risk factors in addition to age and obesity, GSD risk increased among females with levels of serum insulin [4th vs 1st quartile odds ratios (OR) = 4.46 (95%CI: 1.71-11.66)] and HOMA IR [4th vs 1st quartile OR = 4.46 (95%CI: 1.71-11.66)]. Better HOMA β-cell function was significantly related to decreased risk of GSD [4th vs 1st quartile OR = 0.16 (95%CI: 0.03-1.70)]. Among males, age and central obesity were the most significant risk factors for GSD. No association of GSD with serum insulin, HOMA IR, and HOMA β-cell was observed among males. CONCLUSION: Serum insulin, insulin resistance, and β-cell dysfunction are risk factors for GSD in females, but not males with type 2 diabetes.

In the recent years, posting online job advertisements has become a major way for a growing number of multinational cor-porations to publicize their employment information and to recruit job seekers. Nevertheless, the language and space of online jobadvertisement are uneven, which may affect the companies to attract and communicate with the potential candidates. Based on thetheoretical framework of moves and steps analysis suggested by Swales(1990) and Bhatia(2004), the study aims to explore thestructural pattern of this genre and to examine the lexico-grammatical features of each move and step. After analyzing four piecesof job advertisements retrieved from different recruiting websites, the study reveals that there are six moves in the whole structureof online job advertisement, among these, three moves are obligatory, named: establishing credential, introducing the position, to-gether with specifying required qualifications, skills, and experiences. Meanwhile, in each move, the positive adjectives, verbs, andfirst person are frequently used to serve the promotional function, and therefore to intensify the communicative purpose. The studymay contribute to the application of genre analysis in business English teaching, and also be instructive to the reading and writingof online job advertisement.

With the aim of providing effective periodontal disease therapeutic method, multilayer membranes which were loaded with drug for guided tissue regeneration were prepared using an immerseprecipitation phase inversion technique. Single layer, bi-layer and tri-layer membranes were fabricated with chitosan used as cartier and tinidazole as medicine model which was loaded on the membrane. The influence of layer on structure and properties of membrane were studied by SEM, UV spectrophotometer and mechanical test. Drug release properties of three types of layer membranes were also investigated. The results showed that release rate could be slown down in both bi-layer and tri-layer membranes （to 11 days and 14 days respectively） and tri-layer membrane lasted the longest. After a process of rapid release, the concentration of tinidazole which was released by the membrane was maintained at an efficient dosage level. Compared with single layer and bi- layer membranes, we found tri-layer membrane could play a role in controlling low-rate drug release especially at the early stage of release, and keep an efficient dosage at affected part for a long period of time. The loss of drug which loaded on membrane decreased from 84.6% for single layer to 13.04% for tri-layer. The mechanical strength of three types of membrane were detected and showed that it could meet the requiremens of clinical practice. The membranes especially with tri-layer could be more valuable in application.
