Healthcare technology has been growing and fostering cooperation between industry, university and hospitals as growth engines in korea. So, the medibio research institutes in hospital have been constructed to promote research and industrialization centering on healthcare technology. The purpose of this study is to investigate the cases of research institutes in hospitals, and search the characteristics of building organization of medibio research laboratory facilities. Case study is investigated by floor plan, homepage and site visits about five research institutes selected in research-driven hospitals. The facility title and size of research laboratory is originated from site area and research building location. The building function include not only the research lab and business office reflecting on the development platform, and but assembly and meeting room in the ground level. Laboratory floor plans have three types, rectangular, rectangular+linear and linear type, one is traditional and efficient, the others are people and friendly. And building core types are correlated with lab space unit modules, single and double side core are shown in rectangular type. All the laboratories are open lab, composed with laboratory bench and research note writing desk facing the lab service and enclosed lab-support area. And they have communication space looking as warm and cozy common area for the innovation, convergence and collaboration. As the high risk of contamination and high standard for safety and security, equipment and facilities are well managed with biological environment including BSC, fume hood, PCR classification, eye washing and emergency shower.
Weight-controlling can be supported by a proper prescription of energy intake. The individual energy requirement is usually determined through resting energy expenditure (REE) and physical activity. Because REE contributes to 60-70% of daily energy expenditure, the assessment of REE is very important. REE is often predicted using various equations, which are usually based on the body weight, height, age, gender, and so on. The aim of this study is to validate the published predictive equations for resting energy expenditure in 76 normal weight and 52 obese Korean children and adolescents in the 7-18 years old age group. The open-circuit indirect calorimetry using a ventilated hood system was used to measure REE. Sixteen REE predictive equations were included, which were based on weight and/or height of children and adolescents, or which were commonly used in clinical settings despite its use based on adults. The accuracy of the equations was evaluated on bias, RMSPE, and percentage of accurate prediction. The means of age and height were not significantly different among the groups. Weight and BMI were significantly higher in obese group (64.0 kg, $25.9kg/m^2$) than in the non-obese group (44.8 kg, $19.0kg/m^2$). For the obese group, the Molnar, Mifflin, Liu, and Harris-Benedict equations provided the accurate predictions of > 70% (87%, 79% 77%, and 73%, respectively). On the other hand, for non-obese group, only the Molnar equation had a high level of accuracy (bias of 0.6%, RMSPE of 90.4 kcal/d, and accurate prediction of 72%). The accurate prediction of the Schofield (W/WH), WHO (W/WH), and Henry (W/WH) equations was less than 60% for all groups. Our results showed that the Molnar equation appears to be the most accurate and precise for both the non-obese and the obese groups. This equation might be useful for clinical professionals when calculating energy needs in Korean children and adolescents.
This study aimed to examine the development and characteristics of the workers with upper limb musculoskeletal symptoms and disorders and to analyze the upper limb musculoskeletal symptoms and disorders for its relationship with the individual socio-demographic characteristics. This study investigated the effect on the limitations of physical activities using standardized surveillance tool and clinical diagnosis. Musculoskeletal symptoms and the limitations of physical activities were examined. The clinical diagnosis of musculoskeletal disorders were carried out by physical examination, radiological examination and electromyography-electroneuronography for 22 workers in kitchen hood assembly process and 50 workers in toggle process of leather product manufacturing. The proportion of workers with musculoskeletal disorders was higher and the DASH score was also statistically higher in female and aged workers with longer working hours, longer household working hours, less leisure/hobby activity and higher physical load. Physical activities component score increased in the following order: workers in normal health, workers with musculoskeletal symptoms, and workers with musculoskeletal disorders as clinically diagnosed. Score for each DASH component increased in the following order: sports/performing arts ability, social activities, specific physical functional activities, work or other regular daily activities, work ability, psychological activities, insomnia and upper limb symptoms. The overall and each component DASH scores were higher in workers with symptoms of status praesens and of more severity, and receiving medical intervention. Musculoskeletal symptoms and disorders are associated with individual socio-demographic characteristics, and DASH score for physical activities of upper limb was higher in workers with musculoskeletal disorders. Musculoskeletal symptoms and disorders have a remarkable epidemiological significance for physical activities, social activities, work or other regular daily activities, upper limb symptoms and insomnia, where work ability, sports/performing arts ability and preventive measure is needed.

This study was conducted at occupational health laboratories in Seoul and Gyunggi district area from December, 1999 to January, 2000. The main purpose of this study was to survey the actual condition of safety and health by questionnaire and checklist and to assess the performance of fume hoods and the airborne exposures to chemicals in the laboratories. The chemicals in the cabinet were not classified by hazardous properties and the compressed gases were not stored safely. The prevalences of laboratories having first aid kits, fire extinguishers, and safety showers were found to be 18%, 55%, and 9%, respectively. Most laboratory workers were not educated for safety and health. Also, there was no performance evaluation for hazards and risks. The fume hoods in laboratories had not been annually inspected by checklist and the face velocity had been checked more than one time in the previous year for only 18% of them. Five percent of fume hoods had the face velocity more than 4.0 m/sec and 17% had no capture performance. Detected organic solvents were methylenechloride, acetone, ethylbenzene, isopropanol, xylene, methylisobutylketone, trichloroethylene, and toluene. The concentrations of organic solvents were much less than the occupational exposure limits proposed by the Ministry of Labor in Korea. This study showed that the actual condition of safety and health was not appropriate for laboratory workers. It is recommended that laboratory workers should be educated for the treatment and storage of hazardous chemicals and compressed gases to improve the working environment of the occupational safety and health laboratories.
This study was purposed to see how men's hair styles of Japan had changed throughout history and results of the study was as follows. There are such evidences as topknots in its primitive styles and wooden combs that several hair styles were tried already in the primitive Jomon Period. In the Yayoi period, bare topknot style without crowns and Mizura style in which hair drop down both ears were popular. In the period of ancient burial mounds, Mizura style was dominative style and varied its form and shape according to classes and status. In the Aska and Nara era, topknot-in-the-crown style in which hair bound in one as in continental style and put in crown or hood, which style was influenced by the Sui and the Tang periods of China. Since the Heian period, topknot-in-the-Ebosi style, binding style, and Karawa style as well as topknot-in-the-crown style came in sight and Sakayaki style became popular in the Kamakura and Muromachi periods. In the Momoyama period, Chasenmage style and Ichomage style were spread widely. In the early Edo era, Wakashumage style and Yaromage style as well as Ichomage style were preferred. In the middle of Edo era in which form and shape of topknot was more distinct symbol of class, status and job than in any other period, Tachmach style under the influence of the Punkin and Honda modes. Sonno style was popular in the late Edo era. There was a drastic disappearance of topknot style by the hair-cutting order during the Meiji Restoration period and civilized hair style of the Jankiri style, a kind of dishevelled hair style without making a topknot was in fashion and continued to the present.

This study aimed to assess the mobility and thermal comfort of personal protective equipment (PPE) among female healthcare workers, taking into account wearers' physique and PPE protection levels. A total of 16 participants (age: 26.3 ± 8.3 y, height: 161.5 ± 7.3 cm, body weight: 57.1 ± 11.0 kg, BMI: 21.9 ± 3.6), representing diverse body types, underwent four PPE conditions: L (Low_Plastic gown ensemble), M (Medium_Tyvek 400), H (High_Tyvek 800J with Powered Air Purifying Respirator [PAPR]), and E (Extremely high_Tychem 2000 with PAPR, Bib apron, and Chemical-resistant gloves). The mobility protocol consisted of 10 different tasks in addition to donning and doffing. The 10 tasks were repeated twice at an air temperature of 24.3 ± 0.1℃, 59±4%RH. Findings revealed a disproportionate relationship between PPE protection and wearer discomfort. Significant differences in clothing microclimate and total sweat rate were observed between the lowest (L) and highest (E) protection levels (p < 0.01), while distinctions among medium levels were inconclusive. Subjective evaluations favored conditions H and L over M and E (p < 0.05), indicating reduced heat, and humidity, increased comfort, and lower exertion. Instances of mobility discomfort, specially in the small body type group, underscored the need for a suitable PPE size system for Korean adult female medical workers. Furthermore, enhancements in gloves, shoe cover, and PAPR hood designs are essential for improving ease of movement and preventing hindrance.
The purposes of this study were to assess the physical activity level (PAL) and the total daily energy expenditure (TEE) as well as to evaluate the validity of prediction equation for the estimated energy requirement (EER) in normal weight and overweight or obese children and adolescents. The subjects comprised of 100 healthy Korean students aged between 7-18. The anthropometric data was collected. PAL was calculated from the physical activity diary by the 24-hour recall method, and the resting metabolic rate (RMR) was measured by an open-circuit indirect calorimetry using a ventilated hood system. Daily energy expenditure was PAL multiplied by RMR. EER was calculated by using the prediction equation published in KDRIs. There was no significant difference in the means of age and height between the 46 obese subjects and 54 nonobese subjects. The weight and BMI of the obese group (60.2 kg, $25.3kg/m^2$) were significantly higher than those of the nonobese group (42.4 kg, $18.4kg/m^2$). However, PAL was not significantly different between the two groups (nonobese 1.45, obese 1.46). TEE of the obese group (2,212 kcal/day) was significantly higher than that of the nonobese group (1,774 kcal/day). EER (individual PA) and EER (light PA) were significantly higher than TEE (p < 0,001); however, EER (sedentary PA) was not significantly different with TEE in the two groups. These results showed that the levels of physical activity were the same as the sedentary activity both in the nonobese and obese Korean students; moreover, the predictive equation for EER published in KDRI overestimated the TEE of Korean children and adolescents. Therefore, in further research, a new predictive equation for EER should be developed for Korean children and adolescents through the doubly labeled water method.

This study is aiming to set a characteristic design and a fashion trend by analyzing hat style trends and fashion images shown in fashion collections in recent seven years. Also, based on the result of the analysis on the five world's major collections, the influence and the interrelation of hat and fashion image were analyzed. The study was performed by the context analysis method and the image evaluation method. In the context analysis method, the 1,391 pictures for hat-styles which were believed to be the standard of fashion style from the S/S season of 1998 to the F/W season of 2004 were analyzed. The research is summarized as follows. Based on the result of the fashion collections, the kinds of hats came Bowler, Beret, Cloche, Capeline, Cap and Hood in order, and Casual, Feminine, Natural, Formal, Romantic, and Mannish came in order for the case of the fashion images for putting on a hat. The result of the analysis on the characteristic of fashion design according to the kinds of hats, the casual image, with highest frequency, was found from all of the kinds except Capeline. Bowler and Cloche were conspicuous in jackets/slacks, Capeline was conspicuous in one-piece shape, and cloth silhouette showed the highest frequency in H type. As for Bowler, the color of cloth and hat was mostly black, and as for Beret and Cloche, achromatic color showed the highest frequency. But as for Capeline, the cloth color, including chromatic color, was various. As for Beret, pattern and material image were various comparatively, but as for other kinds of hats, there were the materials with no pattern and with hard material image.

A comprehensive survey of the available literature showed that in the last few decades, there has been a growing interest in the use of thermoplastic vulcanizates (TPVs). TPVs are the second largest group of soft thermoplastic elastomers (TPEs) after styrene-based block copolymers, and offer a wide range of potential and proven applications, including in mechanical rubber goods, under-the-hood applications in the automotive field, industrial hose applications, electrical applications, consumer goods, and soft touch applications. Over the last two decades, TPVs have shown a strong and steady market growth (~12% per year). Commercialized TPVs are commonly based on blends of ethylene propylene diene monomer (EPDM) rubber and polypropylene (PP), and to a lesser extent on combinations of butyl or nitrile rubber with PP. EPDM/PP TPVs are characterized by finely dispersed crosslinked EPDM rubber particles (particles size varying between 0.5 and $2.0{\mu}m$) distributed in a continuous thermoplastic PP matrix. If the rubber particles of such a blend are small enough and if they are vulcanized well enough, then the properties of the blend are generally improved. This review article introduces various topics and aspects relevant to EPDM/PP TPVs. The development of TPVs, the use of various types of crosslinking systems and co-agents as crosslinking agents for PP/EPDM blends, the morphology and rheology of TPVs, and their typical end-use applications are also reviewed.
Xinjiang Uygur Autonomous Region is the area with the most Muslim populations in China and the costume of this ethnic minority group was influenced from its surrounding environment and religion. Headgear is one of the important costume elements of Muslim ethnic minority such as Kazakh, Kirghiz, Uzbek, and Tadzhik people, and each group has developed narious forms of it. Especially, we can notice characteristics of headgear in Xinjiang Uygur and four ethnic minority groups through women's headgear pursuant to motive of wear, classification of type, differences and comparability with other areas. Thus, purpose of this study is to investigate women's headgear of Muslim ethnic minority in Xinjiang Uygur Autonomous Region. Based on local data at the Xinjiang Uygur Museum, the study referred to Chinese ethnic minority costume and literature data as well as advanced researches related to Islam, and analyzed characteristics of women's headgear of four ethnic groups in connection with Muslim formation background in Xinjiang Uygur. Women's headgear of Muslim ethnic minority in Xinjiang Uygur can be largely divided into three types; cylindrical, conical and hood type. Headgear was influenced not only by natural environment and weather for protection of body, but also by Islam. Along with strong desire for decoration and expression of racial features, it was used as a means of race discrimination and representation of identity. The religion of Islam within these four ethnic groups grew in accordance with tradition of existing nomadic tribes and regional characteristics, and women's headgear developed in various ways added with religious precepts and nomadic features. Taking everything into consideration, it is found that women's headgear of Kazakh, Kirghiz, Uzbek, and Tadzhik people developed, adopting their own living style and features of minority races instead of remaining identical to the headgear type of Muslim countries in other area.
