Since the 1960s, Hong Kongs new towns have been builton the assumption that they could be socially and economically selfcontained entities. A study of the linkage between three new townsand metropolitan area confirms that substantial commuting trips arestill made. The new towns serve as dormitories for people workingin the metropolitan area. The commuters' reliance on publictransport is significant. The towns are thus far from self-containedeven aller 20 years of development. The public transport network,trip rate, peak factor, purpose, mode choice, costs and journey time,are signilicantly different from those originally estimated. Thesemay be related to distance from the metropolitan area,theavailability of modes, the structure of the public transport netwrk,and changs in the economical structure of Hong Kong. lt suggeststhat the direct and indiscriminant importation of Westernplanning practice to plan new towns with an oriental socio-economicsetting deserves critical review.

Turning clearance angle is changed machining characteristics. In this study, the experiments start from choosing two workpiece materials that are machine structural carbon steel, chrome-molyb- denum steel. Then, the experiments show specifically how features of selected materials changed when they were processed with machining operation. In order to find the surface roughness of workpiece materials, the workpiece materials which have higher tensile strength showed much better value of surface roughness in a surface roughness tester. Moreover, process feed rate was compared between 0.05 mm/rev and 0.10 mm/rev. When process feed rate was 0.05 mm/rev, surface roughness has superior results without reference to the quality of the materials.

Even though radio broadcasting is one of the most widespread electronic mass media, its management for survival is getting drastic. The competition among incumbent radio stations becomes challenging due to the market change and environmental evolution. Managing program quality is a critical issue to a radio station to sharpen its competitive advantages. Quality management of radio programs is intertwined with complicated factors. In order to identify the primary factors affecting radio program quality as well as explore the impact level these factors bring, this study adopts modified Delphi method and analytic hierarchy process （AHP） to explore the issues. According to the outcomes modified Delphi method, the factors were categorized into four dimensions： operation, coordination, structure, and improvement. Ten sub-dimensions were followed. Each sub-dimension includes six to nineteen indicators for measuring radio program quality. In total, 72 indicators were identified. The AHP result revealed that the most important weight was given to the operation dimension. On the contrary, the least important weight was placed on the improvement dimension. Among the sub-dimensions, the standard procedure and organizational design were rated more important than the rest. The results could provide some facts to radio managers for future management.

In this paper, estimations of the lower solution bounds for the discrete algebraic Lyapunov Equation (the DALE) are addressed. By utilizing linear algebraic techniques, several new lower solution bounds of the DALE are presented. We also propose numerical algorithms to develop sharper solution bounds. The obtained bounds can give a supplement to those appeared in the literature.

BACKGROUND Extracorporeal shock wave therapy (ESWT) can be applied to variousmusculoskeletal conditions including calcific tendinitis. Muscle injuries can leadto hematomas, and unabsorbed hematomas sometimes cause pain. We report acase of painful hematoma successfully treated with ESWT. To our knowledge, thisis the first reported case of painful intramuscular hematoma treated with *** SUMMARY A 65-year-old man visited the outpatient department for left calf pain withswelling that had persisted since he slipped two weeks prior. The calf pain hadpersisted and was rated visual analog scale 7. On physical examination, there wasa localized, stiff, ovoid mass on his left upper posterior calf. The pain wasaggravated by dorsiflexion of the left ankle or weight-bearing on the left *** diagnostic ultrasonography showed a hematoma in the left gastrocnemiusmuscle;its texture was firm with low heterogeneity. We applied ESWT to thehematoma. His pain decreased immediately to a visual analog scale 3, and themass was softened. The texture of the hematoma became more heterogeneous onultrasonography. Due to planned overseas travel, he returned three months afterthe initial visit to report that the pain and swelling were dramatically relievedafter *** We propose that painful hematomas could be a new indication for ESWT. Furtherinvestigation on the effects of ESWT for hematomas is needed.

Tenofovir disoproxil fumarate(TDF) is a potent nucleo-tide analogue that is recommended as first-line therapy for patients with chronic hepatitis B. The results of a longitudinal study of TDF treatment demonstrated no development of resistance. We observed one treatment-na?ve chronic hepatitis B(CHB) patient who developed TDF resistance after complete viral suppression during long-term TDF treatment. A 37-year-old HBe Ag-positive man received TDF 300 mg/d for 43 mo. The hepatitis B virus(HBV) DNA titer was 8 log_(10) copies/m L at baseline and became undetectable at 16 mo after treatment. However, the HBV DNA titer rebounded to 7.5 log_(10) copies/m L at 43 mo after treatment. We performed full sequencing to find mutation sites associated with virologic breakthrough. The results showed 9 mutation sites, most of which had not been well-known as mutation sites. We changed the therapy from tenofovir to entecavir with a regimen of 0.5 mg once daily. After 4 mo, the HBV DNA titer decreased to 267 copies/m L, and the liver enzyme levels were normalized.
