The induction of a phenotype with preoperties may have clinical significance in the acceleration of the wound-healing process. Wound contraction involves a specialized cell known as the myofibroblast. The myofibroblasts can be identified by their intense staining of actin bundles with anti-actin antibody. Tissue-specific actin distribution is correlated with the contractile activity of the myofibroblasts and smooth muscle etc. This study was performed to determine the expression of actin filaments in the cytoplasm of cultured human gingival fibroblsts after GaAs laser(BIOSAER, Korea) irradiation. Human gingival fibroblasts were cultured from explants of normal interdental gingival tissue. The third-generation fibroblasts were used for immunohistochemical study. The cultured fibroblasts were exposed $0.53joule/cm^2$(lmW, 7 mimutes) of energy density, and then observed by immunohistochemical method using, rabbit anti0gelsolin, hen smooth muscle polyclonal antibody(Chemicon international inc.), and biotinylated goat anti-rabbit IgG(Vectastain) 24-, 36-, 48-hour after laser irradiation Following results were obtained ; 1. In nonirradiated cultures, round shaped active fibroblasts with abundant cytoplasm and prominet nucleoli were observed. 2. In 24- and 36-hour cultures after laser irradiation, spindle shaped cells with long process were observed. The intensity of stain was seen in cytoplasm of these modified fibroblasts. 3. In 48-hoour cultures after laser irradiation, stained spindle shape cell were not observed. The results suggest that the effect of the galium-arsenide laser treatment on cultured gingival fibroblasts is the rapid development of cytoplasmic actin filaments.

Background: Vitiligo is a depigmented disorder, causing serious cosmetic problems for patients. In diagnostic and therapeutic aspects, vitiligo should be differentiated from other hypopigmented disorders as the therapeutic approach and prognosis are different for each disease. Objective: This study aimed to compare the usefulness of several markers for melanocytes or melanin in differential diagnosis of vitiligo. Methods: Twenty-eight patients were studied, who were diagnosed clinically as suffering from one of the following diseases: vitiligo, nevus depigmentosus, pityriasis alba, postinflammatory hypopigmentation, and idiopathic guttate hypomelanosis. Skin samples (frozen or paraffin-fixed) were obtained from depigmented patches and normal neighboring skin (control). Histological staining was performed by using Fontana-Masson, S-100, MART-1, and DOPA. The staining level of lesional skin was compared with that of normal skin. Results: When the staining level of vitiligo was compared with that of others, vitiligo was significantly lower in Fontana-Masson (13.3±17.2% vs 44.4±23.7%), S-100 (49.5±14.9% vs 74.7±24.2%), MART-1 (7.4±8.7% vs 68± 33.9%), and DOPA (9.5±11.3% vs 58.2±29.5%) (p<0.0001). Conclusion: MART-1 and DOPA are valuable markers in differential diagnosis of vitiligo. However, Fontana- Masson, a marker of melanin, had some limits in detecting melanocytes, and S-100 showed non-specific staining other than melanocytes. (Korean J Dermatol 2008;46(5):569∼577)

우리나라의 경제질서는 다양한 시대적 징표가 공존하는 우리현실을 반영하듯 자유와 통제의 양 극점 사이에서 인정되는 국가간섭의 폭을 매우 넓게 설정하고 있다는 점에서 사회적 시장경제질서라는 표현으로는 적어도 부족하거나 부정확하다고 볼 수 있으며, 우리의 경제헌법에서 어떤 질서체계를 도출한다면 혼합경제체제가 가장 타당하다. 즉 경제환경의 변화에 따라 다양한 경제목표의 추구를 위해 국가는 강온의 수단을 폭넓게 동원할 수 있으며, 이것이 단기간에 고속성장을 할 수 있게 한 법적 배경도 되었다. 그러나 국가의 경제간섭은 정확한 문제인식과 올바른 처방을 할 때 만이 긍정적 효과를 볼 수 있는 것이고, 그렇지 않으면 오히려 어떤 개입도 하지 않는 것 보다 못한 상황이 될 수도 있다. 오늘날 회자되는 경제의 위기론 역시 그 연장선 위에 놓여 있다. 우리의 경제헌법적 질서에 따르면 위기인가 아닌가에 대한 현실인식에서부터 구체적 처방에 이르기까지 국가가 선택할 수 있는 수단은 다양하다. 폭넓고 예리한 경제간섭이라고 하더라도 위헌으로까지 이르기에는 그 거리가 너무 멀다. 따라서 현행 헌법을 전제로 한다면 국가가 어떤 현실인식 위에 어떤 경제정책적 노선을 선택할 것인지에 대한 최종결정은 국민의 몫으로 돌아가야 한다. 즉 선거에 정당과 후보자는 자신들의 경제정책적 노선에 대한 분명한 입장과 방향을 제시하고, 그것에 근거하여 국민들이 판단하고 선택해야 하며, 그것이 바로 헌법이 정하고 있는 정치체제로서의 민주주의 원리와 경제질서로서의 혼합경제체제를 조화시킬 수 있는 통로가 되어야 한다. 결국 올바른 선택의 果實도 잘못된 선택에 대한 책임도 모두가 국민들의 몫이다.

This study was conducted to investigate local residents` recognition on offshore wind farm construction and drawing implications. The survey questionnaire used in this research was conducted in order to find an approach method that could improve receptivity. The survey result first showed that local residents expect positive economic effects from offshore wind farms. Secondly, it was discovered that the decision-making process was mainly conducted by the town`s general assembly and leaders of the area. Thirdly, it was found that the existing national projects conducted in the area brought a high degree of negative effects. Fourthly, the local residents replied that they trusted the leaders of the area ( the town leader, the fishing village chief etc) and most of them followed the local civic group and the public officials within the district. Fifthly, there was no big difference between the recognition of offshore wind farms measured after the first announcement and the current one. However, the recognition between ones who approved and disapproved evolved into more diverse opinions after time had passed. Last of all, collective (community indemnification), medium & long term indemnification and direct indemnification (in cash) had a higher preference towards the construction of offshore wind farms. The most important thing was that conduction commonly required the minimization of damage to fisherman and conflict within the area. However, in Gochange, people were also interested in minimizing the damage of natural landscapes and water pollution. The above results showed a significant difference among regions and it was found that there was a meaningful difference among occupations. In short, the offshore wind turbine was expected to bring no positive changes to local residents, but for regions that showed high preference, further research on differential effect analysis and promotion strategies is required. Also, more efforts are needed to strengthen the partnership between area leaders, while various indemnification plans must be prepared. In addition, the fact that there is no difference in changes of recognition shows that other approach strategies must be searched in the meantime. Last of all, persuading local residents, building partnership between them, and understanding of local public officials are required.

본 연구는 제품에 표기된 정보의 위치가 소비자 인식에 미치는 영향을 식품 패키지에 표기된 영양성분의 정보 위치를 통해 검증하고자 하였다. 연구 1의 결과, 패키지의 영양성분함유량이 위에 위치했을 때는 함유량을 가볍게, 아래에 위치했을 때는 함유량을 무겁게 인식하는 것으로 나타났다. 그러나 정보의 표기 위치가 칼로리에 미치는 후광 효과는 나타나지 않았다. 연구 2의 결과, 수직적 위치와 수평적 위치 간 상호작용은 나타나지 않았다. 연구의 한계점과 시사점을 논의하였다. This study investigates the differences in the consumer perception of nutrition content depending on the location of the content information on food packages. Through two experiments in the food purchasing situation, it was found that consumers perceive the content to be light when the information is located on the top of the packages, whereas they perceive it to be heavy, when it is located in the bottom. However, there were no differences in the perception of consumers in case the information was located on the left or right. In addition, there were no interaction effects between the vertical (top vs. bottom) visual weight and the horizontal (left vs. right) visual weight. Therefore, the location effect showed a partial effect in case of food packages. There were differences in the consumer perception of the content weight depending on the location of the content information on food packages. Based on the results of this study, academic and practical implications have been discussed.

Traditional Marxist studies regarded the productive labour as the production of material goods. So the sevice labors were regarded as nonproduction labor. The same in medical care services. From the perspective of the recent Marxist theory of value, the disticntion between production and nonproduction labor is necessary on medical care services. Medical care service as production labor can properly explain the phenomenon about industrialization, privitization and capiltalization in health care sector. Especially Korean medical services shows the many features of capitalizaion. This article argues that the main reason why Korean medical costs rise too high in last 10 years and that the features of production labor in medica service can demonstrate more properly than traditional perspective.
