In this study, 340 Korean women were surveyed to analyze the impact of the type of sunscreen and use status on the satisfaction of products and resale. Studies have shown that indoor activity is higher than outdoor activity, and both simple and complex sunscreen is often used to compensate for skin tone. Out of single sunscreen, sun cream was used and air cushion was used a lot. Although product usability and UV protection indices were important factors in purchasing, 30% experienced side effects while product satisfaction and willingness to repurchase were high. The recognition of safety, Effectiveness, convenience, usability, satisfaction, and repurchase were all higher than that of composite UV-blocking products, and among subcomponents of product usage recognition, the level of convenience, efficacy, usability, and safety affected satisfaction and repurchase in order. Consequently, the perception of simple UV protection products was higher when using products for UV protection, and its convenience had a significant impact on satisfaction and resale.

The purpose of this study was to investigate the difference in Korean 4-year-olds' cognitive development depending on variables concerning ecological system variables, predictive influences among these variables, and different predictive patterns between working mothers and non-working mothers. The subjects consisted of 998 4-year-olds, derived from the Korean Child Panel data of 2012. The results were as follows: First, 4-year-olds' cognitive development was different depending on their sex, education level of mother and father, mothers' working status, quality of home environment, and mothers' involvement in children's life in their institution. Second, mothers' involvement in children's life in their institution, children's sex, quality of home environment, and mothers' working status predicted 4-year-olds' cognitive development. Third, there was a different pattern of predictive influence among variables according to the mothers' working status. The mothers' involvement in their children's lives in their institution and children's sex was proved to be important in both, but that was more significant in working mothers, and the quality of home environment predicted cognitive development only in working mothers. These results were discussed in terms of necessity of the Korean national policy to support young children's cognitive development efficiently, especially for working mothers.

To determine the composition of benthic species on the southwest coast, a macrobenthos study was conducted at 18 sites on the islands of Wando and Jodo for seven summers (2014-2021) from June to September. Two hundred and twenty species(645 ind./m²) were collected on the rocky shores of Wando and Jodo. A similar number of species was observed in Wando (165 species) and Jodo (167 species). The mean density was higher in Wando (726 ind./m²) than in Jodo (564 ind./m²). The number of species was the highest at Site 15 (116 species), and the density was highest at Site 7 (1,664 ind/m²). The dominant species were Nodilittorina radiata with 175 ind./m² (27.1%), Littorina brevicula with 97 ind./m² (15.1%), and Heminerita japonica with 41 ind./m² (6.3%). The climate change indicator species, Tetraclita japonca, appeared in 15 sites, and the endemic species, Ptilohyale bisaeta, appeared in some sites. Fusinus spectrum, which appears on the Red List as a Near Threatened (NT) species, the lowest level of extinction risk, appeared in Jodo. The macrobenthos of Wando and Jodo demonstrated the general characteristics of rocky shores in Korea. Based on the tides and substrate, the rocky shores revealed a vertical distribution trend where Nodilittorina radiata, Littorina brevicula, Chthamalus challengeri, and Reishia clavigera were dominant. Wando and Jodo exhibited similar habitat distribution patterns.

Power shoulder look is most noticeable trend in women's wear in the 09/10 season. Specially jackets with sharper angle and wider shoulder became the best item since then, and were chosen for must-have item by fashion directors. Jacket occupied 50% in power shoulder items. Its shoulder angle was from 0 to 30 degree but items with 15 degree stood out among them. There are three methods to make power shoulder look jackets; shoulder extension method with moving shoulder tip up and sleeve cap height, method of extension and cutting sleeve cap with shorten shoulder length, and method of extension and moving shoulder tip up in the sleeve with shoulder line like raglan sleeve. As a result, shoulder angle is higher, starting point of shoulder line is closer to side neck point and shoulder point is extender to outside for appearance and fit. In shoulder extension method, the arm hole line was drawn with care by matching joining shoulder seam and setting the sleeve into the arm hole. In sleeve cap transformation, it is desired that starting point shoulder angle is moved closely to side neck point. In case of the sleeve with shoulder line, it needs to consider enough ease of shoulder and upper arm. For making patterns of power shoulder look jacket, it need to consider arm hole line, shoulder length, shoulder point position, sleeve cap height and sleeve width with interpretation design facts. In this study, through the analysis clothing construction method of power shoulder jacket, it is of help to pattern making for various power shoulder design items.

This study's aim was to find a patterns of network dynamics focused on multicultural education contents within the teacher's guide books which are based on national kindergarten curriculum. It was analysed that the 43 guidebooks(2009 Educational activities and materials guidebooks for kindergarten, 11 and the Nuri curriculum teacher guidebooks for the age of 3-5, 32) were analysed using the UCINET 6 program with multicultural education contents frameworks. The findings were as follows: First, multicultural contents' density is connected to life theme of the Nuri curriculum was higher than the 2009 kindergarten curriculum. And life theme with high connectivity was 'I and my family' in the 2009 kindergarten curriculum and 'animals, plants and nature'(3 years old), 'kindergarten and friends' & 'I and my family'(4-5 years old) in the Nuri curriculum. Second, the highest connection content was 'having interests in culture' & 'knowing similarities and differences' in the 2009 kindergarten curriculum, and 'having interests in culture' & 'promoting a sense of community' in the Nuri curriculum. Finally, multicultural education for young children according to the national educational curriculum transition was changed from 'identity' to 'interaction and cooperation'. It means that the Nuri curriculum is more focused on international knowledges and competencies as a world citizen. It suggests the directions for multicultural education for young children in the future.

This study analyzed the inflow and outflow patterns of emergency department patients, to identify changes in regional types in cities, counties, and districts in Jeonlado, Korea. Data of areas in Jeonlado for 2014 to 2018 were extracted from the National Emergency Department Information System. The extracted data includes the patients' and emergency medical institution addresses, which were used to calculate the relevance index (RI) and commitment index (CI). The calculated indices were classified into regional types by applying cluster analysis. A non-parametric method, Kruskal-Wallis test, was employed to examine the differences between years for RI and CI by regional types. The results of cluster analysis using the relevance and commitment indices revealed three regional types. Regions in cluster 1 were classified as outflow type, in cluster 2 as inflow type, and in cluster 3 as self-sufficient. RI and CI were calculated for each cluster or regional type. There were no significant differences between years in cluster 2 (inflow type) and cluster 3 (self-sufficient type). In cluster 1 (outflow type), there were no significant differences in CI between the years; however, there were significant differences in RI between 2014 and 2017, and 2014 and 2018. It is difficult to see that the emergency medical environment has improved due to the increased concentration of emergency medical care.

Background: In pathogenesis and prognosis of lung cancer, significance of enormous types of genetic expression were very compounding and undetermined. We performed this study to search association between clinical characteristics and expression of COX-2, MMP-9 and p53 in non-small cell lung cancer. Methods: Ninety-one patients with adenocarcinoma or squamous cell carcinoma were enrolled. We had searched clinical data retrospectively and performed immunohistochemical staining for COX-2, MMP-9 and p53. We had analyzed significance of these three genes in clinical features and prognosis for survival. Results: 1) In squamous cell carcinoma, male was predominant and was significantly correlated with smoking. 2) Major prognostic determinants for overall survival were curative resection. 3) Expression of COX-2 was more frequent in adenocarcinoma than in squamous cell carcinoma. 4) Negative staining of COX-2, MMP-9 and p53 was more frequent in squamous cell carcinoma than adenocarcinoma. 5) Survival duration was longer in the group with positive expression of p53 and negative for COX-2 and MMP-9 (median duration of survival = 165.6 weeks) than groups with the other expressional patterns. 6) Significant correlation was found between expression of MMP-9 and COX-2. In squamous cell carcinoma, expression of MMP-9, COX-2 and mutant p53 were mutually correlated. 7) COX-2 expression was significant prognostic factor for survival in resected cancer group. In unresected inoperable non-small cell lung cancer group, MMP-9 was statistically significant prognostic factor for overall survival. Conclusion: COX-2 and MMP-9 might have some roles for progression or prognosis in some selected patients with non-small cell lung cancer. COX-2 and MMP-9 may have some roles for disease progression or prognosis in selected patients with NSCLC.

1. Backgrounds and Purpose : Pruritus, one of the most common dermatological symptoms, was clinically examined with a view to a better understanding of its characteristics for more accurate treatment. 2. Method : For 22 months from November in 1997 to September in 1999 we selected outpatients who had consulted for itchiness more than twice in the department of Sasang Constitution of the Pundang Oriental medical hospital, Dongkook University, and 59 of those (35 males and 24 females) were confirmed of their course of treatment. From their medical records and history, we learned the general characteristics and patterns of pruritus, and the qualities and effects of its various treatments. 3. Result and Conclusion : Pruritus was more complained by men than by women and the largest age groups were 20's and 30's. For its suffering period, the duration of 1 month to less than 1 year was the greatest, and most patients had already experienced western medical care. Itchiness affected them almost day and night. In addition, many patients had abnormal bowel habits as a general symptom. According to Sasang Constitution, the Soeumin gave sleep disturbance and indigestion; the Soyangin showed a different pattern in their tongue coatings and bowel habits; the Taeumin had different tongue coatings and sweating pattern. The commonly prescribed herbal formula for pruritus was Gakhangjungisan, Yangkyuksanhwatang, Chungsimyonjatang. As for their efficiency, 61.0 % of patients improved, whereas 39.0 percent did not. Patients aged over 30 showed a more significant improvement than those of 20 years or under, and the duration of less than 1 year was more significantly improved than that of 1 year or more. Those who had no experience in western medical care or had been continuously treated showed a more significant improvement than those with intermittent treatments, and severe pruritus was more significantly improved than mild pruritus.

The aim of this retrospective study was to evaluate the demographic characteristics of pediatric dental patients who underwent dental treatment under general anesthesia (DTGA) at the Seoul National University Dental Hospital from January 2011 through December 2020 and compare the patterns of repeated DTGA between dental patients with severe disabilities (DSD) and non-DSD (healthy or medically compromised patients without DSD). There were 1,857 DTGAs among 1,719 patients (mean age = 5.1 years; males = 59.3%; ASA 2 or above = 52.9%; DSD = 26.8%). Overall, 6.6% of patients underwent repeated DTGA, and the rate of repeated DTGA over a 10-year period was 7.4%. ASA 2 or above (p < 0.0001) and DSD (p < 0.0001) were more likely to undergo repeated DRGA compared to ASA 1 and non-DSD. At both GA1 and GA2, DSD received significantly more restorative treatment on permanent teeth than non-DSD (p = 0.002, p < 0.0001, respectively). There has been an increasing demand for DTGA in pediatric dentistry over the last 10 years. Regular check-ups and preventive oral health care are necessary for pediatric dental patients with severe disabilities to reduce the possibility of repeated DTGA.

The authors surveyed the inhabitants of a rural area to assess the patterns of medical utilization on dermatoses. Seven hundred and sixty new outpatients of dermatoses were examined and surveyed with formed questionnaire from March 1997 to February 1999. The results are as follows; 1. Among 760 new outpatients, the number of male patients was 283(37.2%) and that of female patients was 477(67.3%). 2. The most common dermatoses was Tinea pedis(34.9%), and follows senile pruritus, contact dermatitis, housewife eczema, seborrheic dermatitis, numular dermatitis, atopic dermatitis, Tinea corporis, Tinea ungium, acne vulgaris, impetigo, keratolysis exfoliativa, chronic urticaria, Tinea cruris and Molluscum contagiosum in orders. 3. Drug store was the most frequent places where patients initially visited for their skin diseases(39.6%) and followed by non dermatologic clinic, dermatologic clinic and general hospital in orders. 4. One hundred and twenty one(15.9%) patients have been experienced folk treatment. It was founded that the topical vinegar application or soaking was the most common method. Many patients felt no symptom improvement after the folk treatment(48.8%). Seventeen point four percent of patient felt symptom worsened. The results of this study suggest that many of the rural inhabitants are lack of understanding on their dermatoses. So many physician who are in charge of the primary care in rural area have to pay attention to the common dermatoses and educate patients on their medical utilization.
