The purpose of this study is to present our elderly welfare policy and welfare facilities for the elderly and to propose the future direction of policy for the elderly with comparison to that of Japan. The comparative study results of Korea and Japan are as follows: As the basis of elderly welfare, care insurance for the elderly is now fixated in the two countries. On the other hand, for quantitative expansion in Korea, the quality level has been gone down. Due to qualitative evaluation, the growth of facilities has slowed and material welfare providers was also a decline in the number of operators. Two countries in the field of community welfare in recent years has been actively promoting. It is the most important to solve the social welfare problem with local councils who know the area, which is a part of the future to focus and to support. Due to huge construction investment of facility, there is the burden of operators. This facility is appropriate for an extension of the home. However, it is in the hard economic times. Until now, the number of people in a room is at least four according to the legal standard of Korea, there are a few private rooms. On the other hand, in Japan, unit-care was phased since 2002 and private rooms have been expanded. In Japan, health center for the elderly plays an important role with special elderly nursing home among facilities for the elderly. Health center provides services that are recovering, nursing, and caring to support independence for the elderly after acute phase of treatment. As treatment and care, the aim of health center is to return the elderly to home. On the other hand, there are a few health centers for returning the elderly to home in Korea. Furthermore, in Japan, a project for preventive care has been begun. The project is needed in Korea.

최근 관세청이 15개 수입소비재 품목 가격을 분석한 결과, 수입가격 대비 국내 판매가격은 2.1-4.8배 수준인 것으로 나타났다. 이는 아직도 독점 수입업체들이 폭리를 취하고 있다는 것을 보여주는 결과이다. 독점 수입업체가 아닌 제3자가 제품을 수입할 수 있는 병행수입은 1995년 이미 허용되었으나, 위조품 논란, A/S문제 등 때문에 실제 소비자 후생으로 이어지지 못했다. 정부가 최근 병행수입 활성화 정책을 펴면서 지난해 규모가 3조원으로 늘었으나, 아직 전체 소비재 수입의 5%에 불과하다. 관세청이 정식통관 제품이라는 것을 보증해주는 통관인증제 대상 업체와 품목 확대로 통관 인증업체가 344개로 늘어난 것은 매우 다행스런 결과이다. 이에 본 연구는 현재 국내 병행수입 시장의 실태와 문제점을 분석하고, 정부의 "독과점적 소비재 수입 개선방안"의 검토를 통해 향후 병행수입 제도가 국내 경제 활성화와 수입시장의 경쟁 제고를 위해 나아가야 할 방향을 제시하고자 한다.

The economic growth and highly industrialized society have increased the demand for electricity power. As a result, concerns were focused on the energy resource scarcity and global warming. That is why the photovoltaic generation system to address these concerns has been in the spotlight recently. In this thesis, a utility interactive photovoltaic generation system was operated experimentally for the purpose of promoting the spread of the photovoltaic generation system in the future. Also, the effect of the type of array structure has on the performance of the photovoltaic generation system was evaluated quantitatively and by analyzing the comprehensive operating characteristics, the following results were obtained. In the demo system operated for a year, the average irradiation was measured to be 455,076 $[W/m^2]$ and the maximum irradiation to be 626,622 $[W/m^2]$ in May, up 171,546 $[W/m^2]$ or 38[%] compared with the average irradiation. The minimum irradiation was observed to be 294,022$[W/m^2]$ in December, down 161,054 $[W/m^2]$ or 35[%] compared with the average irradiation. The generation power in situation where there is plenty of irradiation was more than the average one, and the generation power in the fixed system amounted to 32[%], the single-axis tracker to 37[%], and the dual-axis tracker to 39[%]. The generation power in situation where there is little irradiation was less than the average one, and the generation power in the dual-axis tracker amounted to 41[%], the single-axis tracker to 40[%], and the fixed system to 36[%].

기업의 사회적책임 이행이 단일기업의 노력만이 아닌 공급망 전체의 노력으로 이루어진다면 보다 효율적이며 동기부여 측면에서 효과적인 사회적책임이 이루어질 것으로 예측할 수 있다. 이를 "사회적책임의 SCM적 접근"이라고 간주하면 SC-CSR(Supply Chain - Cooperate Social Responsibility)을 통해, 단일 기업의 사회적책임 이행보다는 공급망전체의 사회적책임 이행이 그 효과가 클 것이라고 예측할 수 있다. 현재의 사회적책임 이행에 대한 동기부여에 공급망에서의 사회적책임 이행요구 또는 이행실시 등이 더해진다면 미래의 사회적책임에 대한 동기부여는 더욱 강화되는 것을 실증하였다. 본 연구는 사회적책임의 이행 특히, 중소기업의 이행을 위해서는 단일 중소기업의 사회적책임 이행의지보다는 공급망 전체의 이행요구와 분위기가 촉매역할을 하여 사회적책임의 이행의지를 높이는 것을 SC-CSR적 접근을 통해 실증하였다.

Cyclin E, a key coordinator of the G1 to S transition in the cell cycle, may be deregulated in several malignancies, including breast cancer. The most significant aberration in cyclin E is its elastase mediated proteolytic cleavage into tumor specific low molecular weight isoforms (LMW-Es). LMW-Es are biochemically hyperactive and biologically drive tumorigenesis in transgenic mouse models. Additionally, expression of LMW-Es has been correlated with poor survival in breast cancer cases. Here we determine whether expression of LMW-Es in a breast cancer cell line that is naturally devoid of these deregulated forms would alter their progression through each phase of the cell cycle. The results revealed that LMW-Es expression resulted in an increased doubling time, concomitant with a predominant increase in the population in the S phase of the cell cycle. Moreover, downregulation of p53 in LMW-Es cells resulted in additional shortening of the doubling time and enrichment of cells in the S and G2/M phases of the cell cycle. Furthermore, expression of LMW-Es sensitized cells to ${\beta}$-estradiol (E2) mediated growth and changed expression patterns of estrogen receptor and Bcl-2. Intriguingly, expression of LMW-Es could surpass anti-apoptotic effects raised by p53 upregulation. Taken together these studies suggest that overexpression of LMW-Es in collaboration with p53 loss results in altered g rowth properties of MCF-7 cells, enhancing the oncogenic activity of these ER positive breast cancer cells.

Saussurea involucrata is a Mongolian medicinal plant well known for its effects in promoting blood circulation, and anti-inflammation and analgesic functions. Earlier studies reported that Saussurea involucrata has anticancer activity. The purpose of this study was to confirm the anticancer activity of an ethanol extract of Saussurea involucrata against hepatic cancer and elucidate its mechanisms of action. Hepatocellular carcinoma cells were tested in vitro for cytotoxicity, AO/EB staining for apoptotic cells, apoptotic DNA fragmentation and cell cycle distribution in response to Saussurea involucrata extract (SIE). The mRNA expression of caspase-3,-9 and Cdk2 and protein expression of caspase-3,-9, PARP, XIAP, Cdk2 and p21 were analyzed through real time PCR and Western blotting. Treatment with SIE inhibited HepG2 cell proliferation dose- and time-dependently, but SIE only exerted a modest cytotoxic effect on a viability of Chang human liver cells. Cells exposed to SIE showed typical hallmarks of apoptotic cell death. Cell cycle analysis revealed that SIE caused G1-phase arrest in HepG2 cells. In conclusion, Saussurea involucrata ethanol extract has potential cytotoxic and apoptotic effects on human hepatocellular carcinoma cells. Its mechanism of action might be associated with the inhibition of DNA synthesis, cell cycle (G1) arrest and apoptosis induction through up-regulation of the protein expressions of caspase-3,-9 a nd p21, degradation of PARP and down-regulation of the protein expression of Cdk2 and XIAP.

Objectives : The purpose of this study is to compare hair and alopecia of Korean Medicine with those of western medicine. Methods : We studied relationships between hair and essense(精), qi(氣), blood(血), five vicera(五臟) and meridians(經絡) through literature review about hair and alopecia. We compared Korean medicine with western medicine on physiology of hair and treatment of alopecia based on the study. Results & Conclusion : 1. Congenital essense(先天之精) is related with genetic factor and acquired essence(後天之精) is connected with nutritional factor. Defending function of Defense qi(衛氣) is related with immune reaction and qi stagnation(氣鬱) is associated with stress reaction. Atrophy of vascular tissues observed in alopecia scalp means deep relationship between blood(血) and alopecia, further deficiency of blood can cause telogen effluvium. 2. Kidney qi(腎氣) is related with inhibiting combination of Androgen receptor and Dihydrotestosterone(DHT) or activating hair growth factior. Pi(脾) is connected with alopecia seborrheica caused by damp-heat(濕熱) and alopecia areata caused by excessive prudence(思慮過度). Heart(心) is associated with atrophy in vascular tissue of scalp and liver(肝) is connected with metabolism. 3. Armpit hair and pubic hair as secondary sex characteristics are realated with Yangming Meridian(陽明經) and beard and hair at crown part where Type II $5{\alpha}$-reductase is activated much are associated with Taiyang Meridian(太陽經). 4. Juglandis Semen pharmacopuncture and Ganoderma lucidum pharmacopucture have better effects on inhibit $5{\alpha}$-reductase than Finasteride. Minoxidil and PRP are similar with promoting blood flow and removing stasis(活血祛瘀). Seven-star needling(七星針) is similar with microneedling. 5. Alopecia can be caused by due to lack of circulation Views we need solution to improve circulation coincide in opinion with Korean Medicine and Western medicine.
