In order to investigate the influence of being self-consciousness of one's body size on clothing behavior we measured body size of Korean female college students directly and examined by questionnaire the degree of being self-conciousness of their body size the aspired clothing behavior and the actual clothing behavior. In addition after classifying the subjects into groups according to the degree of obesity we also examined the difference in the actual clothing behavior among the groups./ The results are as follows: 1) On the item of girth of the body parts the subjects felt thicker in the proximal and lower part of the body than in the distal and upper part of the body. And with respect to the style which exposes body silhouette the disparity between the aspired and actual clothing behavior was greater in the parts that the subjects felt thick. 2) After investigating the relationship between the aspired and the actual clothing behavior we found out that the style which subjects wanted to put on but actually did not was the style that exposes body silhouette and the style which subjects didn't want to put on but actually did was the style covers the body silhouette. 3) There was significant correlation between the subjects' consciousness of their body size and their actual clothing behavior. The self-consciousness of body size on actual dressing tend to influence the clothing for lower body more than the other parts. 4) The subjects were classified into lean normal and obese groups. There were significant differences among the groups in the frequency of wearing the clothing that expose body silhouette. The obese group had a tendency to avoid this clothing style.

This study considers the correlation between model pose and clothes in Patrick Demarchelier's fashion photos as well as expression characteristics. The conclusions of the study are as follows. The type of model pose in Patrick Demarchelier's fashion photos can be categorized into five types: maximized type of upper and lower body part, minimized type of upper and lower body part, maximized type of upper body and minimized type of lower body part, minimized type of upper body and maximized type of lower body part, basic type of upper and lower body part. In case of having examined the correlation between body movement and costume, the clothes in the model pose included in the maximization of the body were formed mainstream by silhouette, which was formed by decorative elements or full drapery. In the model poses included in the reduction of the body, the costume tended to expose many parts of the body to provide a simple or structural silhouette form. The costume was expressed in colorful form and poses assumed without body movements. The expression characteristics of the model poses in Patrick Demarchelier's fashion photos were sensuality, dynamicity, and simplicity. First, sensuality was expressed as feminine sensuality accompanying an erotic mood by naturally emphasizing a woman's breast or leg by reducing the body. Second, dynamicity provided a vividness to the image as if directly living and moving by highlighting the rhythmic aspect of the body. Simplicity aroused the effect of paying attention to clothes or other incidental elements rather than the image expressed by the body of a model by excluding body movement.

The purpose of this study was to observe the effect on the removal of dentinal smear layer and morphological changes of reduced dentin surfaces by various dentin surface conditioners. Thirty-two healthy human premolars extracted due to periodontal or orthodontic reasons were used. The teeth were cross-sectioned to expose dentin at the middle portion of the crown with diamond rotary saw. The specimens were then divided into 8 groups. The sectioned dentin surfaces in group 1 to 4 were grinded with No. 400 grit silicone abrasive paper and those in group 5 to 8 were cut with #700 carbide bur under air-water spray. The grinded or cut dentin surfaces were conditioned with 3% $H_2O$, Dentin Conditioner(GC Inter. Corp., Japan), and Scotchprep(3M Dent Prod., U.S.A) according to manufacturer's directions. All the specimens were dried in room temperature for 48 hours, and gold-coated with Eiko ion coater(Eik-engineering Co.), and observed in Hitachi S-450 Scanning electron microscope at 15-25 KV. The following results were obtained; 1. The dentin surfaces grinded with the silicon abrasive paper were rougher in texture and heavier in amount of smear layer than those cut with the carbide bur. 2. Scrubbing of 3% $H_2O_2$ was not effective in removing dentinal smear layer. 3. 20-second conditioning of Dentin Conditioner (GC Inter. Corp) resulted in the removal of a significant amount of the smear layer without removing the tubular plugs and dissolving the peritubular dentin. 4. Scotchprep removed the smear layer very effectively. But at the same time it dissolved the peritubular dentin. 5. Irrespective of the uses of the silicon carbide abrasive paper or the carbide bur the morphological changes of dentin surfaces treated with the same conditioning agents were similar.

High-temperature superconducting coated conductors (HTS-CCs) are good candidates for resistive superconducting fault current limiter (RSFCL) applications. However, the high current density they can carry and their low thermal diffusivity expose them to the risk of thermal instability. In order to find the best compromise between stability and cost, it is important to study the heat transfer between HTS-CCs and the liquid nitrogen ($LN_2$) bath. This paper presents an experimental method to monitor in real-time the temperature of a quenched HTS-CC during a current pulse. The current and the associated voltage are measured, giving a precise knowledge of the amount of energy dissipated in the tape. These values are compared with an adiabatic numerical thermal model which takes into account heat capacity temperature dependence of the stabilizer and substrate. The result is a precise estimation of the heat transfer to the liquid nitrogen bath at each time step. Measurements were taken on a bare tape and have been repeated using increasing $Kapton^{(R)}$ insulation layers. The different heat exchange regimes can be clearly identified. This experimental method enables us to characterize the recooling process after a quench. Finally, suggestions are done to reduce the temperature increase of the tape, at a rated current and given limitation time, using different thermal insulation thicknesses.

Nitrite plays a major role in inhibiting the growth of foodborne pathogens, including Clostridium botulinum (C. botulinum) that causes botulism, a life-threatening disease. Nitrite serves as a color-fixing agent in processed meat products. However, N-nitroso compounds can be produced from nitrite, which are considered as carcinogens. Thus, consumers desire processed meat products that contain lower concentrations (below conventional concentrations of products) of nitrite or no nitrite at all, although the portion of nitrite intake by processed meat consumption in total nitrite intake is very low. However, lower nitrite levels might expose consumers to risk of botulism poisoning due to C. botulinum or illness caused by other foodborne pathogens. Hence, lower nitrite concentrations in combination with other factors such as low pH, high sodium chloride level, and others have been recommended to decrease the risk of food poisoning. In addition, natural compounds that can inhibit bacterial growth and function as color-fixing agents have been developed to replace nitrite in processed meat products. However, their antibotulinal effects have not been fully clarified. Therefore, to have processed meat products with lower nitrite concentrations, low pH, high sodium chloride concentration, and others should also be applied together. Before using natural compounds as replacement of nitrite, their antibotulinal activities should be examined.

Objective: These experiments were conducted to investigate the optimal expose length of propidium iodide (PI) and bisbenzimide on differential staining of mouse blastocysts. Materials and methods: A total 964 blastocysts (early${\sim}$hatched) was exposed to PI (n=831) (group I: $\leq$ 10; II: $11{\sim}15$; III: $16{\sim}20$; IV: $\geq$21 sec) and bisbenzimide (n=133) (group A: $\leq$1; B: $1{\sim}$3; C: $\geq$ 4 hr) in several periods for differential staining. Statistical analysis was performed using t-test with SigmaPlot-2001. P-values < 0.05 were accepted as statistically significant. Results: In case of PI exposure, differential staining rates were significantly higher (p<0.05) in group I (89.8%) than in any others (group II: 77.6%; III: 29.6%; IV: 22.2%) and higher (p<0.05) in group II than in group III and IV. In case of bisbenzimide exposure, differential staining rates were not statistically differences in three groups (group A: 97.4%; B: 87.8%; C: 93.3%). Conclusion: The differential staining rates of mouse blastocysts are not affected by the exposure length of bisbenzimide. However, blastocysts were exposed to PI with period of shorter than 15 sec show best outcomes of differential staining rates.

Background: Organizational changes that involve healthcare hospital departments and care services of health districts, and ongoing technological innovations and developments in society increasingly expose healthcare workers (HCWs) to work-related stress (WRS). Minimizing occupational exposure to stress requires effective risk stress assessment and management programs. Methods: The authors conducted an integrated analysis of stress sentinel indicators, an integrated analysis of objective stress factors of occupational context and content areas, and an integrated analysis between nurses and physicians of hospital departments and care services of health districts in accordance with a multidimensional validated tool developed in Italy by the National Network for the Prevention of Work-Related Psychosocial Disorders. The purpose of this retrospective observational study was to detect and analyze in different work settings the level of WRS resulting from organizational changes implemented by hospital healthcare departments and care services of health districts in a sample of their employees. Results: The findings of the study showed that hospital HCWs seemed to incur a medium level risk of WRS that was principally the result of work context factors. The implementation of improvement interventions focused on team development, safety training programs, and adopting an ethics code for HCWs, and it effectively and significantly reduced the level of WRS risk in the workplace. Conclusion: In this study HCW resulted to be exposed to occupational stress factors susceptible to reduction. Stress management programs aimed to improve work context factors associated with occupational stress are required to minimize the impact of WRS on workers.

Slips and falls are associated with many occupational injuries in Korea. It is also estimated that slipping are major contributors to slip, trip and fall injury burden. So "LOCAL RULE ON OCCUPATIONAL SAFETY AND HEALTH STANDAR D" must be improved, especially article 3(prevention of slip, trip and fall). The primary purpose of the present study is to determine if, and to what extent, the standard could be improved in present environment. In order to fulfill our objective, the another regulation in Korea and foreign countries were investigated and reviewed. Many kind of standard, mandatory documents and guideline were also reviewed. And then, regulations, standard, guideline etc. reviewed were compared with each others. The article 3 was revised as below. 1. The floors of the traffic route in workplace shall have no hole or slope, or be uneven or slippery so as, in each case, to expose employees to slip, trip and fall risk, except if adequate measures have been taken to prevent a employees falling. 2. The employer shall design, install and fix the drain for effective drainage if fluid contaminants were frequently occurred. So far as is reasonably practicable, An employer shall keep the workplace clean, sanitary, and dry so that employees won't have any risk to tripping or slipping at the workplace. 3. To facilitate cleaning, every floor, workplace, and passageway shall be, so far as is reasonably practicable, kept free from protruding objects, splinters, holes, etc. Also, some criteria was developed in this study. Standard and criteria developed in this study will help to prevent slip, trip, and fall injuries.

조선후기는 근대 서민 문예의 부흥기로서, 서민문예의 대두와 더불어 일어난 서민계층의 등장은 복식에 있어서의 대중 복식 문화를 부각시키면서 복식의 유행현상이 나타나게 되었다. 이 시기 모든 계층의 여성 복식에서 공통적으로 풍미한 유행사조는 과장된 치마허리 그리고 둔부를 volume감 있게 강조한 치마등을 통해 여체를 드러낸 선정적인 silhouette이 나타났다. 유교 규범에 의해 억제되고 절제된 여성들의 복식행동(clothing behavior)에서 이처럼 육체를 긍정한다는 것은 사회의 일정한 진보단계에 위치한다고 보겠다. 그것은 Eroticism자체는 영원한 인간의 본능에 의존하겠지만, 이 Eroticism을 통하여 어떤 사회적 질곡을 벗어나려고 하는데에 있어서는 그 Eroticism의 발로가 사회적 의의를 가지는 것이다. 그러므로 조선후기의 여성복식에서의 Erotic Mode는 여성들 자신의 것인 동시에 그 사회의 것이며, 그것은 가식적이고 표면적인 유교적 도덕관의 외피 속에 흐르고 있는 인간성의 폭로이고, 그것을 표현할 수 있다는 데에 서민문예의 진보성과 근대성이 있는 것이다.
