Protective coveralls are very uncomfortable to work in comparison to ordinary top and bottom separated clothing. A pattern maker has to consider the size of the human body and human motion range when designing protective coverall patterns. It is difficult to produce well-fitted coveralls because of the lack of readymade patterns despite the increased need for protective coveralls at various jobs. Patterns are decomposed by unsewing 18 products in the domestic market to provide the fundamental information on developing patterns for protective coveralls. The characteristics and differences of pattern types are compared after grouping patterns with information taken from the analysis of the shapes and measurements of patterns from the acquired patterns. The results of the analysis showed that on-market protective coveralls were less curved but much linear when compared to ordinary clothing patterns; however, the breasts and crotch circumferences were very loose and bulky, which is quite different from the other all-in one style working clothes. For the pattern shapes, patterns are classified into waistline-seamed and bustline-seamed types. The result of the hierarchical cluster analysis with 27 measurement variables were classified into four groups. Types by shape and measurements were related to each other; therefore, we expect the information of each type to be used in developing protective clothing patterns.

월경은 모든 여성에게 불가피한 현상으로 이 기간에 이르는 불편의 경감은 여성의 풍요로운 삶을 위한 중요한 과제이다. 본 연구에서는 일회용과 다회용 패드 생리대의 소비자 사용평가를 통하여 생리대 사용에 따른 실질적인 문제점을 파악하고 소비자의 니즈에 맞게 개선하기 위한 기초 정보를 제공하는 데 목적을 두었다. 연구결과, 월경에 대한 응답자의 증상은 긍정보다는 부정적인 측면이 우세하여 생리기간이 고통스러운 경험으로 인식되고 있었으며 일회용 생리대와 다회용 생리대의 디자인, 성능, 맞음새, 사용감, 관리에 대한 긍정적, 부정적 평가 내용에 차이가 있었다, 스왓분석을 통해 일회용 생리대는 사용 편리성이 강점인 반면, 착용감이 약점으로, 다회용 생리대는 착용감이 강점인 반면, 관리 불편이 약점으로 제기되었다. 이러한 결과를 반영한 감성 설계가 이루어진 다면 소비자는 보다 쾌적한 생리 기간을 영위할 수 있으며 궁극적으로 생산업체에 수익을 가져오는 상승효과를 불러올 수 있으리라 기대한다 Menstruation being an inevitable phenomenon for every women, reducing the discomfort during the menstruation period is one of the important issues for women`s well-being. This study was conducted through user evaluations on disposable pads and reusable pads to comprehend the discomfort factors of the sanitary pads and to provide basic information for improvement. Negative symptoms of the reponses on menstruation outnumbered the positive aspects, and the results suggested that menstruation period was perceived as a painful experience to women. There were difference between the negative and positive responses regarding the designs, functions, fittings, wearing sensations. and disposabilities of disposable pads and reusable pads. While disposable pads had the strength of convenient use, it had the weakness of wearing sensation, and while reusable pads had the strength of wearing sensation, it had the weakness of inconvenient keeping. When designs reflecting these results are made, it is expected to bring a synergy effect by bringing both a more pleasant menstruation period for the consumers and eventual profit to the manufacturers.

Indium hydroxy sulfide (In(OH)xSy) as a cadmium (Cd)-free buffer layer for CuInGaSe2 (CIGS) solar cells was prepared by the chemical bath deposition (CBD) and the reaction time was optimized. The band gap energy and transmittance data alongside the thickness results from the direct observation with focused ion beam system (FIB) could be a powerful tool for optimizing the conditions. In addition, X-ray diffractometer (XRD), X-ray photoelectron microscopy (XPS), and scanning electron microscope (SEM) were also employed for the layer characterization. The results indicated that the optimum reaction time for In(OH)xSy buffer layer deposition by CBD was 20 min at 70 ℃ under the conditions employed. At the optimum conditions, the buffer layer thickness was near 57 nm and the band gap energy was 2.7 eV. In addition, it was found that there was no XPS peak shift in between the buffer layers deposited on molybdenum (Mo)/glass and that on CIGS layer.

Foot and Mouth Disease (FMD) is highly contagious and highly lethal to cloven-hoofed animals. In the winter of 2010, an outbreak of FMD in Korea caused a great deal of economic damage as well as serious mental and physical damage to people who participated in preventive activities. This study provides preliminary data for designing safe and functional protective clothing and gear for individuals who participate in FMD preventive activities. This study was accomplished with multilateral methods such as a documentary survey, field trips, sample analysis of protective clothing and gear, questionnaire studies and focus interviews. As a result, we found that most workers wore low-priced protective clothing that was low in safety functions and rarely wore extra protective gear. Also pointed out was dissatisfaction with: protective clothing and gear, problems related to damage, discomfort, contamination, problems in protective gear related to waterproof functions, protection against harmful substances, discomfort, coldness, and damage. Safe protective clothing could be developed that protects the actual wearers if these results are reflected in the improvement of protective clothing and gear.

Pants is an item of clothes of which physical suitability for improvement of appearance and movement is greatly emphasized. The pattern design of pants is very important because the fitness of crotch region, which is difficult to measure, is structurally essential in pants. This study gives detailed pattern development data for the future pattern design by considering design factors related with crotch region of pants and by suggesting related data. For this study, we measured and analyzed the measuring size of each parts of pattern and the design methods related with crotch region selecting 20 textbooks used in universities and institutes of higher education. Through this study, crotch region of pants pattern related design data were obtained and this result could be a primary information in development and education of pants pattern.

Solid dispersions were prepared to increase the dissolution rate of biphenyl dimethyl dicarboxylate (DDB) using water-soluble carriers such as povidone, copolyvidone, 2-hydroxypropyl-β-cyclodextrin (HPCD), sodium salicylate or sodium benzoate by solvent evaporation method. Solid dispersions were characterized by infrared spectrometry, differential scanning calorimetry (DSC) and powder X-ray diffractometry, dissolution and permeation studies. DDB tablets (7.5 ㎎) were prepared by compressing the powder mixtures composed of solid dispersions, lactose, corn starch, crospovidone and magnesium stearate using a single-punch press. DDB capsules (7.5 ㎎) were also prepared by filling the mixtures in empty hard gelatin capsules (size No. 1). From the DSC and powder x-ray diffractometric studies, it was found that DDB was amorphous in the HPCD or copolyvidone solid dispersions. Dissolution rates after 10 min of DDB alone and solid dispersions (1 : 10) in sodium benzoate, sodium salicylate and copolyvidone were 11.8, 23.5, 22.8 and 82.5%, respectively. Dissolution rates of DDB after 30 min from 1 : 10 and 1 : 20 copolyvidone solid dispersions were 80.5 and 95.0%, respectively. For the DDB tablets prepared using solid dispersions (1 : 20), the initial dissolution rate was dependent on carrier material, and was ranked in order, Kollidon 30 《 copolyvidone < HPCD. For the HPCD solid dispersion tablets, dissolution rate reached 97.4% after 15 min, but thereafter slowly decreased to 80.7% after 2 hr due to the precipitation of DDB. However, in the case of copolyvidone solid dispersion tablets, dissolution increased linearly and reached 93.4% after 2 hr. Reducing the volume of test medium from 900 to 300 ㎖ markedly decreased the dissolution rate of the tablets containing 1 : 20 HPCD solid dispersions and 1 : 10 copolyvidone solid dispersion. For 1 : 20 copolyvidone solid dispersion tablets, there was no significant change in dissolution rate up to 1 hr with different volumes of test medium. Preparation of the copolyvidone solid dispersion (1 : 20) in capsules markedly delayed the dissolution (31.2 % after 2hr) due to the limited diffusion within capsules. The permeation rate (13.4 g/㎠ after 8 hr) of DDB through rabbit duodenal mucosa from copolyvidone solid dispersion (1 : 10) was markedly enhanced, when compared with drug alone or physical mixtures. From overall findings, DDB formulations containing copolyvidone solid dispersions (1 : 20) could be used to remarkably improve the dissolution rate in dosage form of powders and tablets.
