With signs of the redevelopment of the domestic sewing industry, national support agencies were established. This study aims to assess the present conditions of the domestic sewing industry and investigate the effectiveness of national sewing industry support policies. According to the results of a survey of 30 sewing companies managers, the biggest factor causing product defects was work being rushed because of tight delivery dates, and the reduction in sales was caused by a lack of orders. Moreover, sewing technicians are aging, and the biggest reason for their decrease in number is that people do not pursue the job because of the common understanding that it is difficult. Managers perceived that the government's sewing technician training program was not a practical help. They were well aware of the support program to improve the work environment and the sewing equipment support program and showed high satisfaction with these programs, but they complained that the period for equipment rental was fixed. A majority of them thought that the Korean sewing industry environment had still not improved, and were skeptical about its future outlook. They identified its most urgent needs as the expansion of orders and the securing of manpower. The support programs that they wanted urgently included support for employees' four major public insurances and the enactment of the increase of toll processing fees.

The average increase in life expectancy obtained as a gift of modern science cannot hold itself responsible for extended life's happiness. It admits of no argument that the necessity of social preparation for minimizing bad health and longevity of unhappiness to aged people who are in the state of these continuous growth. Recently, because of an aging trend, targeting on elderly housing expected continuous increased demand in housing market, this study is to comprehend it's characteristic and offer implications. For the characteristic of elderly housing, firstly it needs scientific analysis of related theory and analysis of statistical data. Also this study aims to look through and suggest an alternative included the special matters of Korean society with advanced foreign country's analysis of an alternative. And judging from economic characteristics of elderly housing to be presented as an important factor, choices of housing according to economic level are anticipated to show different forms. In future, to supply elderly housing, therefore, the introduction of the concept of housing providing various opportunity of choice is necessary. If studies proceed through expanded alternative, it is judged to be able to draw more varied results in elderly housing. Also, if going along with political dimension study, it is expected to offer more specific and effective solutions of the problem of elderly housing.

A specially designed flat plate was mounted vertically over the axial line in the wind tunnel of the Pusan National University. Strain balances were mounted in the trailing part of the plate to measure the skin friction drag over removable insertions of $0.55{\times}0.25m^2$ size. A set of the insertions was designed and manufactured: 3 mm thick polished metal surface and three compliant surfaces. The compliant surfaces were manufactured of a silicone rubber Silastic$^{(R)}$ S2 (Dow Corning company). To modify the viscoelastic properties of the rubber, its composition was varied: 90% rubber + 10% catalyst (standard), 92.5% + 7.5% (weak), 85% + 15% (strong). Modulus of elasticity and the loss factor were measured accurately for these materials in the frequency range from 40 Hz to 3 kHz. The aging of the materials (variation of their properties) for the period of one year was documented as well. Along with the drag measurement using the strain balance, velocity and pressure were measured for different coating. The strong compliant coating achieved 5% drag reduction within a velocity range $20{\sim}40$ m/s while standard and weak coatings increased drag reduction.

In this article, we review the differences of the brain morphology according to age, sex, and handedness. Age is a well-known factor affecting brain morphology. With aging, progressive reduction of brain volume is driven. Sex also has great effects on brain morphology. Although there are some reports that the differences of brain morphology may originate from the differences of weight between the 2 sexes, studies have demonstrated that there are regional differences even after the correction for weight. Handedness has long been regarded as a behavioral marker of functional asymmetry. Although there have been debates about the effect of handedness on brain morphology, previous well-established studies suggest there are differences in some regions according to handedness. Even with the studies done so far, normal brain morphology is not fully understood. Therefore, studies specific for the each ethnic group and standardized methods are needed to establish a more reliable database of healthy subjects' brain morphology.

In this study, we investigated the unit process parameters in spherical $UO_2$ kernel preparation. Nearly perfect spherical $UO_3$ microspheres were obtained from the 0.6M of U-concentration in the broth solution, and the microstructure of the $UO_2$ kernel appeared the good results in the calcining, reducing, and sintering processes. For good sphericity, high density, suitable microstructure, and no-crack final $UO_2$ microspheres, the temperature control range in calcination process was $300{\sim}450^{\circ}C$, and the microstructure, the pore structure, and the density of $UO_2$ kernel could be controlled in this temperature range. Also, the concentration changes of the ageing solution in aging step were not effective factor in the gelation of the liquid droplets, but the temperature change of the ageing solution was very sensitive for the final ADU gel particles.
