The purpose of this study was to understand the experiences of art therapists who work with LGBTQ+ clients. Participants of this study were five art therapists who had more than 10 sessions with and at least one case involving an LGBTQ+ client. All participants were interviewed in depth. The collected data were then analyzed using Giorgi's phenomenological method. Based on the analysis, the following seven themes were identified: “meeting with LGBTQ+ clients,” “feeling a lot of emotions at first meeting with clients,” “understanding and sympathizing with LGBTQ+ client‘s suffering,” “having difficulties in art therapy with LGBTQ+ clients, helping to accommodate oneself as a sexual minority,” and “growing up as therapists and individuals.” According to the results the process of art therapy with sexual minority clients is the same as that of with non-sexual minority clients. In addition, therapists also viewed some experiences as “special” due to meeting LGBTQ+ clients. The implications of the results and study limitations were discussed based on the above results.

Synthesis and Characterization of a Quantum-dot doped Silica Network Prepared by Using a Microemulsion

유정하,김종성 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.41

We have prepared a quantum-dot (QD)-doped silica network by using a microemulsion method and investigated the fluorescent properties of the hybrid particles for biological imaging and bioconjugation. The size of the particles was measured by using an electrophoretic light scattering system and transmission electronic micorscopy (TEM). The optical properties of the particles were characterized with an UV-Vis spectroscope, a photoluminescence (PL) spectrometer, and a fluorescence microscope.

Although the advancement of modern medicine, the treatment of diabetes mellitus is very difficult until now. Diabetic gangrene, one of the angiopathic and neuropathic complications, is a common complication of diabetes mellitus, and shows an increasing tendency. Diabetic gangrene needs surgical treatment in almost all cases and its treatment is very difficult because of the peripheral vascular disease or small vessel disease. The authors reviewed in 364 patients of diabetic gangrene that treated in our hospital, from January 1989 to September 1994. We analysed the incidence of diabetic gangrene, duration of diabetes, predisposing factors, result of bacterial culture, other diabetic complications, result of treatment of diabetic gangrene according to the level of amputation and primary healing rate. We summarized the obtained results as following. 1. The overall incidence of diabetic gangrene was 2.16%. 42.3% of diabetic gangrene patient were in over 50 year group. 2. 65.4% of patients with gangrene suffered diabetes longer than 5 years and up to 14 years. 3. The most common predisposing factor was local pressure (54.7%). The most common site of gangrene was big toe (33.0%). 4. Bacterial infection were shown in 80% of cases. The most common organism was staphylococcus (65.9%). 5. The most common associated diabetic complication was retinopathy followed by neuropathy, nephropathy in order. 6. According to the Wagner's classification, grade 2 lesion was most common (41.5%). 7. The most common surgical treatment was debridement and splite thickness skin graft (59.9%). 8. The overall primary healing rate was 85.5% and recurrence rate was 10.7%.

Hypertrophic scars remain one of the most vexing problem faced by the surgeon. Despite many recent studies, the ultimate cause for the abnormality in the wound healing process remains obscure. Hypertrophic scar represent benign proliferative connective tissue growths with an overabundance of collagen synthesis as opposed to collagen lysis. Therefore the objective of treating a hypertrophic scar is to catalyse or accelerate the ultimate spontaneous resolution of the scar by increased collagen lysis and a return to a normal and lasting collagen synthesis-collagen lysis balance. But the existing methods for treatment of hypertrophic scars including surgery, injection, silastic sheet or pressure wraps have a number of limits in clinical application such as poor result, complexity & time factor. We adopted Henderson's method in the treatment of hypertrophic scars, that drills many tiny holes of 1mm depth on the surface of scar with CO₂ or Argon laser. We performed this procedure in 15 patients who had various size & location of hypertrophic scars, and analyzed the result from 3 months to 28 months after laser theraphy. We summarized the obtained results as following. 1. The symptoms & textures of scars are improved mark edly after treatment of CO ₂laser. 2. The scars in the area of high skin tension showed poor improvement. 3. The symptoms & textures of scars has not recurred in all improved cases.

Objective: Studies have shown that turnover intention of teachers’ in early childhood educational centers tend to negatively affect the quality of child care and children’s adjustment. However, few studies have examined the underlying mechanism that increases teachers’ turnover intention and have barely focused on environmental factors. We aimed to test whether workplace characteristics may affect teachers’ turnover interntion through personal factors (i.e., burnout and health). Methods: A sample of 262 teachers participated in the study. Workplace characteristics, burnout, health and turnover intention were assesed through self-report questionnaires. Data were analyzed through SEM using Mplus and the significance of mediation effects were estimated by the bootstrapping confidence intervals. Results: Finidngs indicated that a poor workplace enviornment directly predicted high turnover intentions of teachers and indirectly predicted through their high burnout and poor health contidion. Conclusion/Implications: These findings contriubed to provide better understaning about an effective future direction for policies and intervention programs in order to decrease teachers’ turnover intention and subsequently increase the quality of early childhood educational centers.

남성복의 변화에 관한 연구

The present thesis aims to contribute to the further development of the men`s wear industry in Korea, which, now confronts the need to adjust itself more actively to the conditions of the coming age of internationalization and free trade. To achieve this, this thesis suggests, the trade should proveid for the changing domestic needs on the one hand and refine its wares as high value-added products in competition with those from the advanced countires in fashion industry on the other. The history of the `suit`, the standard men`s attire, dates back to 1850, when the `Ditto suit` was introduced, composed of coat, waist coat, vest, and trousers, to remain virtually unchanged till the end of the nineteenth century, and the modern men`s wear originated in Britain. In Korea, since the introduction of western clothes from 1876, custom-made suits had been dominant until 1994, while weatern clothes earned popular currency between 1945 and 1964, and ready-made suits began to spread, with their advantages recognized in terms of practicality, convenience, and functionality. The next phase form 1965 to 1985 witnessed the establishment of a unmber of ready-made brands, although custom-made suits stayed in their height of prosperity until 1975. The turning point for the men`s wear industry came in 1975, when hihg-calss ready-made brands be-gan to turn up, with the arrival of large companies in the market, matching the change in consumers` life style. The men`s wear market went through further diversification and specialization during the years between 1985 and 1990. Aroudnd the year 1990, however, the expansion of the business suit industry came to slow down, accompained by an oversupplied market. The fashion of pragmatism in the 1990 calles for the growth of the casual wear department, and as consumer`s life style became more and more individualized, conscious dressing in accordance with T.P.O(i.e. Time, Place, and OCcasion) established itself as an important branch of culture. such casual boom is likes to aid in promoting Korea`s men`s wear industry to peer with that of advanced countries. Consumers` fashion sense is now ahead of the trade`s as well as being shortcycled, highly individualized, stylized, and diversified. To meet consumers` demands under such circumstances, each company is required to develop its unique soft Know How, based on accurate information and strategically specialized planning. The trade should convert its hitherto producer-oriented strategy to a new consumer oriented one, and actively lead the needs and purchasing pattern of consumers, by providing and effecient and reasonable price policy with optimum supply of merchandise and also by presenting `our` trend suited to our circumstances.
