The purpose of this study was to provide basic data necessary for the development of clothing that can improve the satisfaction of body shape of elderly men by examining subjective characteristics and characteristics of perception type of older men's body shape. Using the Q methodology, I investigated and analyzed the process of formation and main characteristics of subjectivity of various types of recognition that elderly men express about their body shape. There were four types of perception of body shape in elderly men: flat hip and bird legs skinny body, back bent and abdominal obese body, thick neck and upper body development body, forward cervical neck and protruding abdomen obese body. The actual body shape of elderly men was classified according to the bust, waist circumference, hip circumference, and body part angle. But recognition body shape of elderly men was classified by visual factors like the abdomen, the angle of the neck, the inclination of the back, the slope of the waist, and the degree of obesity. It is necessary to consider the trend of silver fashion which is increasing in demand. In addition, it is necessary to develop clothing patterns of comfortable fit through ergonomic study on the physical characteristics of older men. Consideration should be given to the design and pattern that can reduce the difference between the ideal body shape and the body shape recognized by older men.

Even though a Han-bok, or traditional Korean costume, should be inherited since it is invaluable part of our culture, research on Han-bok is scarce. Since the development of a Jeogori pattern, the upper garment of Korean traditional clothes, is done mostly based on the chest size, the design does not completely consider on wearer's body shape. Moreover, unless made by an expert, trial and error is almost always necessary to improve the fit of the clothes. In this research, a Jeogori pattern was suggested that improves the fit based on the shape of the upper back(straight or bent) of a female in her late 20s who often wears a Han-bok and is comfortable when moving. Using a 3D virtual clothing system, the optimum pattern was selected based on the body shape. The final selection was made, and each subjects tried the garment on to evaluate the comfort when moving, along with its appearance, based on a seven point Likert scale. As a result, for a straight body shape, the optimum ease for the front bust width was 2.5cm, and that for the back bust width was 2.0cm. The optimum center back dart was 1.0cm. The optimum Geodae width was 7.6cm, and the optimum back Geodae point was 2.0cm. For the bent body shape, the optimum ease for the front and back bust was 2.0cm. The optimum Geodae width was 8.4cm, and the optimum back Geodae point was 1.5cm. Furthermore, if the Hwajang slope was set at half of the vertical distance between the laterals of the neck and shoulder, a fitted silhouette appeared, which is preferred nowadays. In the appearance evaluation, the final pattern designed in this research received higher scores than the original design(straight; p<.001, bent; p<.05). The results of the evaluation of the comfort when moving also showed higher scores for the final pattern that was designed.

Kok-Ryung covers the collar of underwear and protects the neck. It is between outer garment and underwear and its form is bent. According to literature, Cheom-Yu, Keup, and Pang-Ryung belong to Kok-Ryung. Kok­Ryung was used in Yemaek and also it was used as a part of the uniform of government officer in Song Dynasty. The results of the study were as follows: 1) With the changes of the times, Cheom-Yu was used in Ju Dynasty, Pang-Ryung was used in Han Dynasty, and Kok-Ryung was used from Nam-Jo through Soo, Tang, Song Dynasity. 2) Cheom-yu, Pang-Ryung, and Kok-Ryung were all made of long rectangular cloth. How­ever, Chemo-Yu and Pang-Ryung were adjusted in front of the neck, Kok-Ryung was adjusted on the back. 3) The purpose of Kok-Ryung was practial one of sweat clothes at first. But it became for decoration and dignity gradually. Therefore, the users of it were changed from the common people to high government officers. 4) Cheom-Yu, Po-Ryung, Keup, and Pang-Ryung were all a kind of scarf and they are the same with Kok-Ryung in the respect. They were put on between outer garment and underwear or attached under the collar of outer garment. 5) Kok-Ryung of Song-Sa seems to be the round collar the uniform of government officers and it is different from Kok-Ryung of Suk-Myung.

The purpose of this study was to investigate the association between wrong postures and pain during scaling and encourage dental hygienists and students to exercise scaling in a good position. After obtaining informed consent, 107 students (3rd and 4th grade students) who had an experience with scaling practice were enrolled. The questionnaire included three general items, four items related to the posture during scaling, and nine items related to pain management (total 16 items), for which the five-point Likert scale was used. Through the questionnaire, we examined the preference of posture during scaling, posture education during scaling, pain in each part during scaling, pain management, and pain management method. In the scaling exercise, 86.3% of the subjects were instructed on the correct posture, and 87.9% of the subjects perceived the possibility of inducing musculoskeletal disorders based on the scaling posture. The percentage of subjects who responded that they performed scaling in the correct posture was 33.6% and that of subjects who answered that they bowed or turned their head by more than 15° was 64.4%. Further, 45.7% of the subjects answered that they bent their shoulders, and 29.9% of the subjects answered that their postures were not parallel to the floor. Pain during scaling was still higher when they bent their head, they bent their waist, and they bent their wrist (p<0.05). During scaling, pain was most frequent in the fingers and hands (15%), followed by the neck (14%), shoulders (11.2%), waist (9.3%), and feet and legs (2.8%). The percentage of subjects who performed regular exercise (or stretching) to prevent pain was 29.9% and that of subjects who managed pain after scaling was 12.1%. Further, exercise (24.6%) and self-massage (20.3%) were highly used as the pain management methods, and the school practice was preferred to education media for pain management (79.4%). In the scaling practice, there was a training on pain management, but the frequency of practicing in the wrong posture was high. Moreover, pain increased upon practicing in an incorrect posture. Therefore, more in-depth and systematic education on the necessity and method of musculoskeletal disease management during scaling is required.

To lesson economical loss induced by fumigation in importing country when cut roses are exported, effects of several fumigation temperature, treatments of cut stems (dry or wet), methyl bromide (MB) concentrations, and fumigation periods on the quality of cut roses were investigated. According to results, the most important factor affecting the quality of cut rose was found to be fumigation temperature. When fumigated at $5^{\circ}C$, cut roses showed no chemical damages, e.g., tip burn or bent neck, and maintained their quality for the same duration as that of control, regardless of MB concentrations or treatments of cut stems. However, phytotoxicity by MB increased and vase life of cut rose was shortened as fumigation temperature increased. Timing of fumigation also appeared to be an important factor affecting the quality of cut roses of which phytotoxicity by MB was not observed and thier vase life was not shortened, even if MB was treated up to $40g{\cdot}m^{-3}$, when cut roses were fumigated at $5^{\circ}C$ on the day of harvesting. On the other hand, the degree of damage of cut flowers by fumigation methods or MB concentraions was not consistent with changes in fumigation temperature.

This experiment was conducted to investigate the effect of pretreatments and storage conditions on quality and vase life of cut 'Red Sandra' rose (Rosa hybrida L.). 'Red Sandra' rose flowers were harvested and pulsed with distilled water, 0.2% RVB or 200ppm aluminum sulfate+3% sucrose+50ppm $AgNO_3$+0.1mM ethionine for 22 hours and then stored in wet or dry condition for 12, 24, 48 hours at low or room temperature. Pulsing with aluminum sulfate+sucrose+$AgNO_3$+ethionine delayed bent-neck, increased solution absorption and flower diameter, and prolonged vase life rather than pulsing with distilled water or RVB. Storage in wet condition or low temperature also delayed bent-neck, increased solution absorption and flower diameter, and prolonged vase life compared with storage in dry or room temperature condition. As the storage hours prolonged, solution absorption, flower diameter, and vase life were decreased especially pulsing with distilled water. Pulsing with aluminum sulfate+sucrose+$AgNO_3$+ethionine prolonged vase life compared to pulsing with distilled water or RVB regardless of storage conditions and shipping hours.

In order to develop a pretreatment solution for cut rose, the effects of surfactants [Tween 20, Triton X-100, polyoxyethylene 4 lauryl ether (PLE)], germicides (aluminum sulfate, $AgNO_3$, dichloroisocyanuric acid, STS, benzalkonium chloride, 8-hydroxyquinoline sulfate), sucrose, and hormones (ABA and kinetin) on the longevity and quality of 'Red Sandra' were investigated in environment-controlled room. Although 20 and 50 ppm Tween 20, and 500 ppm PLE appeared, in appearance, to be effective in retarding blueing and wilting, respectively, they didn't show statistical differences as compared to distilled water control. Among germicides, $AgNO_3$ was the most effective in delaying petal blueing, petal withering, and reduction of fresh weight, regardless of its concentration, while, in the case of STS, only 1mM treatment was effective in delaying of petal withering. Only 5% sucrose treatment delayed petal blueing, petal withering, and bent neck, but showed no significant difference as compared to 500 ppm aluminum sulfate. Finally, single or combination treatments of ABA and cytokinin were found to rather stimulate the senescence of cut rose.

The purpose of this study is to collect data for he improvement of the accuracy of upper garments construction of the old whose bodies have been changed due to their age. In this study the body measurements with 61 items were taken from 226 men(aged fro m 60 to 80) living in Seoul by the R. Martin's method in 1992. The data were calculate by computer and analyzed by the multivariate method, especially factor and cluster analysis. The results of the study were as follows; 1. The average stature of elderly males was 163.6cm, chest circumference 91.6cm, waist circumference 9\\85.5cm. hip circumference 92.8cm, neck circumference 37cm, arm length 55.4 cm, back length 42.6cm, shoulder breadth 42.9cm and the Roher's Index 1.39, which was a standard body shape. 2. The items of factor analysis were explained to seven, namely, the degree of fatness of the upper body, the size of the frame of body, the length of the upper body, the degree of curve of the front body, the size of shoulder, the shape of the back, and the slope of shoulder. 3. The body types of subjects were classified into four types. The majority was type 4, which was 67% of subjects and considered as balanced body type. The distinctive features of those types are as follows; Type 1. The subjects of this type had a slight skeletal structure and were the thinnest of all the subjects with thin and forward-bent arm. Type 2. The subjects of this type were the tallest of all the subjects. they had the straightest side of body and a well-developed upper arm. The thigh length of this type was longer than the length of trunk. Type. 3. The subjects of this type was only one, so ti could be excluded. Type 4. The subjects of this type had a long trunk, well-developed shoulder, and a crook in their neck and back. The arm length and thigh of this type were short and those circumferences were thick. Type 5. The subjects of this type were the shortest of all, but had the highest degree of fatness in the waist and abdominal. They had well-developed front muscles of body and projected hip.

The study with the subjects at 200 adult males in Busan in their 20s had a purpose at analyzing lateral body shapes to develop men's educational dress forms. The following are the conclusions: 1. Comparison at the Body Dimensions at Busan Male Adults in Their 20s and the 5th Survey at Korean Body Measurement In the comparison at the Busan and national body dimensions by way at Mollison's relative deviation, all compared items were under the deviation of 0.7. Therefore, the sample of Busan male grown-ups is understood io represent the body shapes of the average Korean male adults in their 20s. 2. Results of Lateral Body Shape Classification From factor analysis, seven factors were produced to explain 75.45% of all variables. Those 7 factors to compose lateral body shapes were hip prominence, back-neck sides, upper body's front-back depth, lateral upper body depth, hip-waist depth, front chest-waist depth, and hip and waist height. Cluster analysis revealed four characteristic lateral body shapes. Type 1 with the appearance rate of 11.70%, named D, had the greatest upper chest angle and tanterior neck lower angle. The front side was more developed. Type 2 with 33.51%, named I, was generally long and slender. Type 3 with 24.47%, named d, had the biggest depth differences in hip-chest as well as more prominent back hip. Type 4 with 30.32%, named q, had the biggest dorsal upper angle and the tiniest chest upper angle as the back area was a little bent.
