의복의 개구부 위치가 수분전달에 미치는 영향 -명판형 착의 모형에 의한 측정-

The effect of opening location on the microclimate within the garment was investigated. The vapor pressure of microclimate was determined with the vertical-plate type skin model. For quantitative comparison of the results, water vapor transporting index( $W_{Τ}$) and transmitting efficiency were used. Cotton interlock knit was selected as a specimen. It was found that the opening location had great influence on the microclimate. When the total opening size was same, the order of the rate of vapor transport was waist, armhole<neck and armhole< neck <waist and armhole<neck and waist. Water vapor transporting indices of vertical openings were 3.7~4.6 times those of horizontal ones. The effect of opening location on the microclimate was greater compared with those of opening size or number of opening. The ventilation through neck and waist happened more rapidly by chimney effect than any other openings and its $W_{Τ}$ at 10% openness was 5.6 times higher than in a closed system. The vapor transport through the neck occurred more actively than at the waist by buoyancy draft. When the ventilation was restricted to the waist opening and its openness was increased, the rate of vapor transport decreased rather than increasing. When four openings were opened and the openness increased only at the waist, the rate would increase a little. For effective ventilation through waist openness, it is necessary to open other openings simultaneously. From these results, we could infer that for optimum ventilation, the selection of opening location is very important and the neck and waist are the most desirable location.
의류학 관련 학과의 소속 단과 대학과 학과 명칭 및 교과과정에 대한 연구

The current status of the curricula of departments related to Clothing & Textiles was checked. The names of colleges and departments affiliated with Clothing & Textiles were also examined. Data on introduction of curricula and subjects disclosed on the website of 60 universities were collected, and the total number of subjects collected was 2,306. As a result, the following conclusions were reached: First, departments related to Clothing & Textiles were the most frequently affiliated with the art/design schools. Depending on the name of the department, the colleges they belong to were different. It was found to be related to the name of the department and the name of the college. Second, According to a survey of the percentage of each major area in the curriculum, the portion of the fashion design area was the highest. The results of checking the composition ratio of the major areas according to the department name showed that there were differences in the curriculum according to the department name. Third, we looked for unusual subjects that were not found in other universities, which could be largely summarized into three: those for characterization, those for preparing for the Fourth Industrial Revolution, and those related to the current situation in the department of Clothing & Textiles. Fourth, we examined subjects related to the Fourth Industrial Revolution, and found that words such as ‘sustainable’, ‘convergence’, ‘smart’, ‘knowledge property’ and ‘computer’ were in common. However, the number of subjects was extremely low.

The purpose of this study was to investigate job stressors, job stress symptoms, and job performance of workers in fashion industry. The data were obtained from questionnaire completed by 529 workers who were employed in textile or colthing manufactures located in Seoul, Daegu, Busan, and Masan area. The SPSS package was used for data analysis shich included frequency, mean, correlation, and factor analysis. Job stressors consisted of environmental related stressors, job related stressors(task characteristics and role characteristics) and organization related stressors(organization climate and career development). Most of job stressors were significantly correlated with job stress symptoms but their correlation coefficients were low. Among job stressors, quantitative work overload was found to be a major stressor. Workers in fashion industry appeared to evaluate their job performance relatively good. Also, it was found that behavioral and psychological symptoms were negatively correlated with job performance.
상악동 골 이식술을 동반하여 식립된 임플란트의 변연골변화와 생존률에 관한 후향적 연구

연구목적: 이 연구는 측방접근법을 통해 상악동 골이식을 시행한 후 임플란트를 식립하였을 때, 누적 생존률 및 성별, 연령별, 이식재, 자가골의 공여부, 술전 잔존골 양, 무치악 형태, 식립 시기, 임플란트 종류, 직경과 길이에 따른 임플란트의 생존률 및 변연골의 방사선학적 결과의 차이를 분석하고자 시행되었다. 연구 재료 및 방법: 상악 구치에 측방접근법을 통해 상악동 골이식술 후 임플란트 보철치료를 시행한 71명을 대상으로 하였으며 표면 처리된 나사모양의 임플란트를 사용하였다. Osseotite(BIOMET 3i, Warsaw, USA), Neoplant(Neobiotec, Seoul, Korea), $Br\ddot{a}nemark$(Nobel Biocare, Goteberg, Sweden)과 SSII(Osstem, Busan, Korea)를 사용하였다. 최소 6개월 이상의 기간 관찰 누적 생존률은 Kaplan-Meier 분석법을 이용하였으며 다른 요소에 따른 임플란트의 생존률의 유의성은 Chi-square test로 검정하였다. 결과: 상악동골 이식술이 시행된 모든 증례에서 임플란트 식립이 가능한 골 양이 얻어졌으며 92%의 생존률을 보였다. 결론: 상악동 골이식술을 시행한 후 임플란트 보철 수복은 자가골 단독 사용시에 자가골과 골대체 물질이 혼합된 것보다 우수한 생존률을 보였다. 지연 식립하는 경우가 임플란트와 동시에 식립하는 경우보다 생존률이 높았다. Statement of problem: Insertion of endosseous implants in the atrophic maxilla is often complicated because of lack of supporting bone. Augmentation of the floor of the maxillary sinus with autogenous bone & bone substitute graft has been proven to be a reliable treatment modality, at least in the short term. The aim of this study is to evaluate the factors of implant survival rate associated with maxillary sinus lift with grafts. Material and methods: The sinus floor was augmented with bone grafts derived from modified Caldwell-luctechnique(71 subject, 93 sinus, 180 implants), the autogenous bone or autogenous+Bio-oss. Before implant installation the width and height of the alveolar crest were increased in the first stage procedure in 10 patients while in the other 61 patients augmentation and implant installation could be performed simultaneously width and height of the alveolar crest > 4 mm) or delayed installation. Results: In all case bone volume was sufficients for implant insertion. 14 of 180 inserted implants were lost during follow up and the healing period Patient received implant supported overdenture(5 patients) or fixed bridge(62 patients). Conclusion: Within the limit of the result of this study, we conclude that bone grafting of the floor of the maxillary sinus floor with bone for the insertion of implants might be a reliable treatment modality and the autogenous bone graft and delayed installation method might be the factors for good results.
