The purpose of this study was to explore leacher and peer relationships and child development in two types of early childhood program; halfway kindergarten and full-day childcare. The subjects were 90 four and half year old children and their teachers enrolled in 10 kindergartens and 20 childcare centers in Seoul. Each teacher evaluated her children with six scales developed by NICHD Early Child Care Research Network(1996); child-leacher relationship, peer relationship, social competence, adaptive language, behavior characteristics, and behavior problems. The data were analyzed by ANOVA. The results of this study were as follows: First, the girls in both programs had closer relationship with their teachers than the boys. The boys in the daycare were less dependent than those of kinder; on the other hand, the girls in the daycare were more dependent than those of kinder. Second, there was no significant difference in peer relationship between the children in both centers. Third, the girls of both centers scored higher than the boys in social competence. Fourth, in the child's adaptive language, both boys and girls were well developed, but girls were higher than boys, especially in kinder Fifth, the children in both centers behaved attentively in the groups, but in particular, the girths were more attentive. Finally, most of children were received low scores in the behavior problem scale.

A retrospective study of 17 dogs with hyperadrenocorticism (HAC) was performed to evaluate the clinical and clinicopathological outcomes in dogs with pituitary-dependent HAC or adrenal gland-dependent HAC. Sixteen dogs were monitored at day 10, 30 and 90 then every 3 month after first presentation. In each examination, physical examination and ACTH stimulation test and client questionnaire were performed. In 17 cases, eight dogs were successfully treated with mitotane therapy (median dose 16.7 mg/kg; range 5.3 to 50 mg/kg, SID); another one dog showed favorable response, but the clients declined to further treatment before the full control of the disease had been achieved; four dogs showed poor response to treatment. One dog was euthanized due to septicemia. These results showed canine HAC can be medically managed successfully without side effects at the doses used in this study.

The purposes of this study were to: a) examine characteristics of foodservice management practices; b) investigate characteristics of recipients; c) analyze foodservice systems; and d) provide feedback for the efficient and effective foodservice management of mental disorder care sites in Korea. A total of 46 sites was analyzed by questionnaire survey. Statistical data analysis was completed using the SPSS package program for descriptive analysis. As results of site recipients' characteristics, 60% of total sites were males and 40% were female recipients. Average 60% of recipients were from 30 to 40 years old. Major diseases of recipients were mental disorder, high pressure, and obesity. According to the result of foodservice system analysis, the average meal cost per day was about 2,921 won and average food cost percentage was 39%. Average number of meals per day was about 600 meals. All sites had on dietitian and 88.3% of sites had one cook as a full-time employees. In the part of procurement, dietitians were major chargers of sites for purchasing foods. Major purchasing method was the order and delivery contract. About a half of sites used cycle menu system and standardized recipies. Most of sites had recipients survey systems for evaluating meal satisfaction. About 60% of sites provided liquid diets to recepients and 22% provided diabetic diets. Dietitians at sites had problems on low meal cost budget, lack of cooking professionals, and lack of information about treatment meals for mental disorders for providing higher quality of foods cure recipients. The results suggested that financial and systematical supports by the government would be very necessary to meet the goal of nutritional balanced meal services.

End-stage renal disease is a fatal and devastating disease that is caused by progressive and irreversible loss of functioning nephrons in the kidney. Dialysis and renal transplantation are the common treatments at present, but these treatments have severe limitations. The present study investigated the possibility of reconstructing renal tissues by transplantation of renal precursor cells to replace the current treatments for end-stage renal disease. Embryonic renal precursor cells, freshly isolated from metanephroi of rat fetus at day 15 post-gestation, were seeded on biodegradable polymer scaffolds and transplanted into peritoneal cavities of athymic mice for three weeks. Histologic sections stained with hematoxylin & eosin and periodic acid-Schiff revealed the formation of primitive glomeruli, tubules, and blood vessels, suggesting the potential of embryonic renal precursor cells to reconstitute renal tissues. Immunohistochemical staining for proliferating cell nuclear antigen, a marker of proliferating cells, showed intensive nuclear expression in the regenerated renal structures, suggesting renal tissue reconstitution by transplanted embryonic renal precursor cells. This study demonstrates the reconstitution of renal tissue in vivo by transplanting renal precursor cells with biodegradable polymer scaffolds, which could be utilized as a new method for partial or full restoration of renal structure and function in the treatment of end-stage renal disease.

Objective : To assess and compare the clinical outcomes between GnRH agonist long protocol and GnRH antagonist short protocol in oocyte donation program. Materials and Methods: Of total 18 oocyte donation cycles, controlled ovarian hyperstimulation (COH) were performed with GnRH agonist long protocol and GnRH antagonist short protocol in initial 9 cycles and later 9 cycles, respectively. Oral estradiol valerate and progesterone in oil we re administrated to all recipients for endometrial preparation. Oral estradiol administration was started from donor cycle day 1 after full shut down of gonadal axis with GnRH agonist in patients with ovarian function. Progesterone was injected from oocyte retrieval day of donor initially, then continuously till pregnancy 12 weeks if pregnancy was ongoing. We compared the parameters of clinical outcomes, such as number of the retrieved oocytes, fertilization rate, high grade embryo production rate, clinical pregnancy rate, implantation rate, ongoing pregnancy rate, COH duration, total gonadotropin dose for COH between GnRH agonist long protocol group and GnRH antagonist group. Statistical analysis was performed using Mann-Whitney test, p<0.05 was considered as statistically significant. Results: The number of retrieved oocytes, fertilization rate, high grade embryo production rate, clinical pregnancy rate, implantation rate, ongoing pregnancy rate were $14.89{\pm}7.83$, 81%, 64%, 78%, 31%, 78%, respectively in GnRHa long protocol group and $11.22{\pm}8.50$, 79%, 64%, 67%, 34%, 56%, respectively in GnRH antagonist group. There was no significant differences in parameters of clinical outcomes between 2 groups (all p value >0.05). Duration and total gonadotropin dose for COH were $10.94{\pm}1.70$ days and $43.78{\pm}6.8$ vials in 18 cycles, $12.00{\pm}1.73$ days and $48.00{\pm}6.93$ vials in agonist group, $9.88{\pm}0.78$ days and $39.55{\pm}3.13$ vials in antagonist group, respectively. In GnRH agonist long protocol group, significantly longer duration and higher gonadotropin dose for COH were needed (p=0.012). Conclusion: In oocyte donation program, clinical outcomes from controlled ovarian hyperstimulation with GnRH antagonist were comparable to those from GnRH agonist long protocol group, so controlled ovarian hyperstimulation with GnRH antagonist may be effective as GnRH agonist long protocol. At least there may not be harmful effects of GnRH antagonist on oocyte development and quality.

Contemporary people can form a broad social sympathy on cultural products based on the present Korean image. K-pop is good material to use to share korean culture, and fans who are enthusiastic here are increasingly demanding cultural products. The visual materials of Bangtan Boys are collected from their album covers, and a concept book, and divided into specific and symbolic images. Based on this motif, three specific images: 'bulletproof vest', 'army house + superhero extract image', and 'Wings symbol', six designs were proposed. In addition, six motifs from the music videos for recent popular songs, 'Spring Day', 'Blood, Sweat and Tears' and 'Burning Up' were selected as symbolic images. Each selected image is divided into a normal line and a special line. The former is a relatively small, stable, and popular style, and the latter is a large, original, and bold style. By drawing and transforming extracted images and motifs using Adobe Illustrator CS6 and Adobe Photoshop CS6 program, a full-width umbrella design was developed. The messages that the Bangtan Boys wants to convey through their music are put into cultural products that contemporaries can sympathize with. By developing umbrellas, a variety of items and design goods can become desirable points of consumption as high-value products by domestic and foreign fandom. If designs that incorporate various elements of future K-pop contents as well as other Korean Wave contents are developed, it will be possible to develop original design products that will form global understanding.

Today, SPA fills many of the same needs as they did thousands of years ago, including relaxation, wellness and stress relief by incorporating many of the same methods embraced by the ancients such as a multitude of hydrotherapy treatments, thalassotherapy and massage therapy, one of the most widely used SPA treatments. The definition is as follows: SPA is entities devoted to enhancing overall well-being through a variety of professional services that encourage the renewal of mind, body and spirit. It was from here that the concept of modernday SPA evolved, incorporating full health and beauty services along with sport, aquatic and rest facilities. Todays SPA, a absolute concept, is being specialized and spread as fast as undefinable just in a word. Thalassotherapy, a kind of SPA therapy, contains minerals and trace elements. Born more than 4,000 years ago in ancient Egypt, thalassotherapy comes from the Greek words for thalasso(sea water) and therapeia(to heal). Thalassa was the Greek personification of the Mediterranean Sea that surrounded them and gave them so much of their sustenance. It helps to nourish, hydrate and refine skin texture and also eliminate metabolic waste and toxins in the body. Thalassotherapy is recommended for post-natal and postsurgery recovery period, chronic fatigue, circulatory problems, cellulite control and dermatological problems. It's also possible to enjoy the thalassotherapy SPA as a day guest. Be sure to try the jansu massage, given in the heated sea water pool. As a trained therapist gently whisks clients through the womb-warm water, clients can practically feel the toxins leave their body. Many women from all over the world have been kept up beautiful skin with applying thalassotherapy to their faces and bodies since long times and these days in France, they are getting great curative clinical effects from renovative and scientific technological combination. Thus thalassotherapy will be absolutely ultimate form of natural healing which can keep and recover human's health and beauty.
