Background : The clothing is considered as second skin. The patient clothing needs basic clothing demands which are comfortable, functional and aesthetical and special demeands which are associated with medical examination, treatment and management of daily-life inconveniences. The patient is weak and labile to psychic trauma and has limitation of movement. So the help of others is needed. But recent patient clothing does not satisfy above demands. So the design, making and management of patient clothing to satisfy those demands are very important. The purpose of this study' is to develop multipurpose clothing which is comfortable, functional, aesthetical and satisfying patients and medical personnels. Method : The questionnaires of existing patient clothing were tested by patients, medical doctors, and nurses. After analyzing two types of questionnaires, eight types of experimental patient clothing were made. After preference test, shortcomings were removed and merits were adapted. One type of multipurpose patient clothing mixing eight above experimental clothing was made. The state of wearing and moving were videotaped. The videotape-recoding was watched by patient, caregivers(medical doctors, nurses) and clothing specialists. Result : The general reaction for experimental clothing were positive by the group of patients, medical personnels and clothing specialist, there were significant differences among three groups. Conclusion : It was thought that to develop one type of multipurpose clothing is possible. If the studys for patient clothing which are free-size and economic matters that are type of clothes and method of washing are made in depth, the desirable patient clothing will appear.

With increasing numbers of immigrant workers in Korea, the supply of socially and culturally acceptable housing has become an important issue. The purpose of this study was to analyze the state of Goryo-in housing and domestic living conditions in metropolitan areas of Korea. This study will present essential information directly relevant to the establishment of practical housing policy for Goryo-in in Korea. Furthermore, data collected and analyzed here will enable comparative investigation with Goryo-ins who live in Russia and Central Asia. Using ethnographic methodologies, we examined 20 Goryo-in households in relation to their usage of domestic space. The following conclusion were established; 1). The most popular L D K(Living Dining Kitchen)type consisted of kitchen plus one or two bedrooms. The majority of households lived in quarters with separated kitchen and living room areas. 2). Most households had a washing machine in the bathroom due to a lack of space, and they regarded the bathtub and the drain hole of the bathroom as very necessary. The Goryo-ins interviewed preferred quarters with separate bathroom and toilet areas, in order to allow simultaneous use. 3). Their most preferred seating style was chairs, while making Kimchi at home was not very popular. 4). All respondents took their shoes off and wore slippers at home, while also indicating a preference for designated shoes space at the entrance to the house. 5) Half of the households had a carpet or mat in the bedroom or living room, both for keeping warm and aesthetic reasons. 6). All households had modified Ondol heating system and demonstrated satisfaction with this. The majority of Goryo-ins interviewed had a different living style compared to households in Russia and Central Asia which were related to less favorable economic conditions in Korea.

This study analyzed the physical indices, food habits and nutrient intakes of patients with hypertension, to provide better research data for the prevention and the cure for disease as well as basic data for nutrition education. The subjects were 44 patients who visited the general hospital, located in Daegu, to receive hypertension treatment The lifestyle, food habit, nutrient intakes, anthropometric measurements, body fat and blood pressure were measured as main indices. By the BMI, $72.8\%$ of the patients were over weight or obesity $(>23\;kg/m^2)$. In the male group, the WHR tended to increase according to the BMI (p<0.05). In the female group, the body fat tended to increase according to the BMI (p<0.05). The group with more monthly income showed lower systolic blood pressure than the group with smaller monthly income (p<0.05). The scores about food habits concerning balanced diet and preference for salt were low, which implied that food habits of subjects were not desirable. The intakes of riboflavin and calcium didn't meet the RDA requirements. Especially, the lack of calcium was more ap~nt in the female patients than the male ones. Despite this, they had more than enough protein, vitamin C, and iron. The physical indices according to blood pressure revealed that the group of higher blood pressure showed greater WHR (p<0.001). The male group with higher systolic blood pressure showed greater BMI than one with lower systolic blood pressure (p<0.05). As for nutrient intakes according to blood pressure, the group with higher blood pressure had more sodium and iron than one with lower blood pressure (p<0.05). The patients with hypertension tended to be more overweight or obese, preferred salty foods, and were in an unbalanced state of nutrient intakes. Thus more systematic and ongoing measures should be pursued to take care of patients with hypertension.

The objective of the present study is to investigate healing design attributes for adolescent patients and to identify the relationship among healing design attributes and the meaning of home. This study examined the environmental preferences of American adolescents for hospital rooms to investigate age-appropriate healing design attributes. The health-related quality of life (HRQOL) concept was adapted to this study as a theoretical framework. One hundred six American adolescents participated in the survey. Participant adolescents consisted of two groups by their health status: forty-seven adolescent patients who were waiting for their surgical operations in waiting rooms and fifty-nine healthy high school students while they were at school. Participants aged in range from 14-year to 18-year olds with a mean of 16-year olds. Data collection consisted of two different instruments: Emotional state survey with demographics and environmental preference survey. Environmental values that are important to adolescents were control of privacy, having outside view, and quiet places to go. However, staying in a single-bed room for hospitalization is ranked the lowest score for the participating adolescents. Adolescents who perceived higher stress level preferred to have quiet places to go, to control over privacy and to have outside view significantly. The study resulted that the most important design attribute for American Adolescents was "privacy control", which is the essence of the meaning of home. There are some significant discrepancies in environmental preferences of hospital rooms by different genders and different health status.

Concerns about how ocean acidification will impact marine organisms have steadily increased in recent years, but there is a lack of knowledge on the responses of macroalgae. Here, we adopt an outdoor continuous-flowing mesocosm system designed for ocean acidification experiment that allows high CO₂ conditions to vary with natural fluctuations in the environment. Following the establishment of the mesocosm, five species of macroalgae that are common along the coast of Korea (namely Ulva pertusa, Codium fragile, Sargassum thunbergii, S. horneri, and Prionitis cornea) were exposed to three different CO₂ concentrations: ambient (×1) and elevated CO₂ (2× and 4× ambient), over two-week period, and their ecophysiological traits were measured. Results indicated that both photosynthesis and growth exhibited species-specific responses to the different CO₂ concentrations. Most notably, photosynthesis and growth increased in S. thunbergii when exposed to elevated CO₂ conditions but decreased in P. cornea. The preference for different inorganic carbon species (CO₂ and HCO₃⁻), which were estimated by gross photosynthesis in the presence and absence of the external carbonic anhydrase (eCA) inhibitor acetazolamide, were also found to vary among species and CO₂ treatments. Specifically, the two Sargassum species exhibited decreased eCA inhibition of photosynthesis with increased growth when exposed to high CO₂ conditions. In contrast, growth of U. pertusa and C. fragile were not notably affected by increased CO₂. Together, these results suggest that the five species of macroalgae may respond differently to changes in ocean acidity, with species-specific responses based on their differentiated photosynthetic acclimation. Understanding these physiological changes might allow us to better predict future changes in macroalgal communities in a more acidic ocean.

The United Nations Convention on Biological Diversity defines biotechnology as "Any technological application that uses biological systems, dead organisms, or derivatives thereof, to make or modify products or processes for specific use" Biotechnology has made tremendous contributions to improve production efficiency of agriculture during the last century. This article reviews successful examples of application of bio-fermentation in improving swine nutrition efficiency mainly based on the authors'z own research experience. Production of feed grade supplemental amino acids by bio-fermentation allowed nutritionists to formulate accurate feed for optimal lean growth and reduced nitrogen excretion. Recent issues with high feed grain prices caused potential feed quality problems. Bio-fermentation allowed nutritionists to use exogenous supplemental enzymes such as phytase and NSPases in swine diets, thereby improving nutrient utilization and reducing nutrient excretion to the environment. Yeast metabolites are also produced by bio-fermentation and have been repeatedly shown to improve milk production of sows during early lactation even though actual mechanisms are still to be investigated. Bio-fermentation technology also allowed nutritionists to prepare vegetable protein sources with large protein molecules and anti-nutritional factors suitable for feeding newly weaned piglets, as selected microorganisms significantly reduce specific anti-nutritional factors and size of peptides. Preparations of vegetable protein sources suitable for newly weaned pigs will greatly contribute to swine nutrition by providing efficient alternatives to the use of animal protein sources that are often expensive and somewhat against societal preference. Considering the few examples listed above, biotechnology has closely influenced improvement of production efficiency in the swine industry. As we have limited resources to produce meat to satisfy ever-increasing global demands, extensive adaptation of biotechnology to enhance production efficiency should be continued. However, at the same time, wise and careful application of bio-technology should be considered to ensure production of safe food and to meet the expectations of our society.

This study proposes medical gowns for interns and residents that address the functions of utility and activity. Based on the questionnaires, the prototype focused on the pockets for practical use and movement adaptability. Functional pockets were made by increasing pocket sizes and separating pockets with sections according to use. An inside pocket and a loop for an identification tag was placed on the chest pocket and the side seam pocket were oblique lined. To resolve horizontal stress on the back of the gown,6 cm action pleats were added at both ends of the bladebone. The elbow area was tucked up to improve the workplace activities. To reduce hamper on the gown hemline, slits were added along the gown side seam. The front button was changed into an inside button closure. The cuffs, belt, and back waist belt were removed due to occupational cases of inconvenience. The length of the sleeves was adjusted with belts to improve the movement of the arms. In accordance with design preference, the gown was designed to be knee-length with wrist length sleeves. Blue colored (2.5PB 3/12: by Munsell) material was inserted to reduce the contamination on the neck, cuffs, front closure, and hemline area. The planning cloth of the experimental gown was designed to improve activity function, cleaning, and comfort from light materials. The field test (with 30 doctors at university hospitals and the objective assessment with 9 subject groups)were done by the valuation between the existing gown and the prototype. The results showed that the prototype had to be modified by decreasing the pocket size, expanding the usage of the penholder, and simplify front pockets in order to maintain unity. The loop for the identification tag, inside pocket, and the blue colored material had to be removed. The front closure of the gown had to return to its original state.
