Objectives : The purpose of this study is to understand the temperature characteristics depending on the thickness and material of the needle used with the Electronic Warm Acupuncture Device (EWAD). Methods : We controlled experimental environment and measured temperature changes of a silicon phantom in which K-type thermocouples were inserted at depths of 2, 7 mm. EWAD perfomed with acupuncture needles of various thicknesses (0.25×60 mm, 0.40×60 mm, and 0.50×60 mm) and materials (Gold 0.40×50 mm). We set non-needle (only heated with EWAD skin heater) group as a control group. Results : The maximum temperature and temperature changes of 0.40 mm, 0.50 mm needle group were significantly higher than the non-needle group. The highest temperature range in all needle groups was 0.50 mm needle group (41.44±0.31℃). However, the 0.25 mm needle group was not significantly different from the non-needle group. Maximum temperature of gold needle group was significantly higher than stainless steel needle group. Temperature changes of gold needle group were higher than stainless steel group at the depth of 7 mm. Conclusions : It was found that needle thickness and material of acupuncture had an effect on the temperature of the EWAD. When performing EWAD treatment, consideration of thickness and material of acupuncture is needed. Future research is needed using phantoms that can reflect actual clinical situations and better mimic the human body.

Contemper nursing literature place much importance on human- centered and individualized care. Nursing research has related stress during hospitalization of adolescent patients to adaptation to a new environment, isolation from friends, limitation due to illness, over protection of parents and communication with member of the medical team. The investigator conducted this study in the hope that an understanding of adolescents responses to hospitalization, their perceptions, the kinds and levels of stress, and the relationships between stressors and individual characteristics would contribute to the improvement of adolescent patient care. The objective of the study was to obtain informations related to the adolescents psychological stress experience during hospitalization, specifically stress from interpersonal relationships and communication, isolation from the family, social or economic problems, illness and from the treatment environment and nursing care. An interview schedule adopted from Holmes and Rahe's Social Readjustment Rating Scale and selected items from Voicer's instrument on stress-producing events was used with 120 adolescent inpatients aged 13 to 18 years three general hospitals in Seoul during Aug. 10, to Sep. 30, 1975. 1. The sample consisted of 66 male and 54 female patients. Sixty-six percent were late adolescents, aged 16 to 18 years: 4% were early adolescents, aged 13 to 15 years. The primary cause for hospitalization was for orthopedic problems (35.8%). More than half of these (54.4%) were due to injury or accident. 2. Stress eclated to illness revealed the highest score (4.97), followed by stress related to treatment environment and nursing care (4.34) , isolation from family and social or economic problems (4.01) and interpersonal relationships and communication (3.96). 3. The perceived indifference of doctors and nurses was a serious cause of stress (mean=4.83). Fellow patients and visitors caused least stress (mean=2.06). 4. Discontinuation of education or unemployment were major stressful events (mean=4.71). Least stressful was isolation from the family (mean=3.47). 5. More than 94% of the respondents expressed fears related to body image (mean=4.97) 6. Within the category of treatment environment and nursing care, items related to restrictions because of treatment, discomfort because of treatment, inadequate explanation from nurses about procedures were rated as severe stress events (mean=4.6). Items related to the ward environment and to having a relative stay with them were seen by the group as less serious events (mean=3.7). 7. Stress related to interpersonal relationships and communication was correlated positively with female patients and those preferring passive activities. (P〈0.05) 8. Stress related to family problems was positively related to female and early adolescent patients (P< 0.05). Stress related to social problems was positively , elated to students and those preferring active pursuits (P< 0.05). 9. There were no correlation between the high stress related to disease and any of the characteristic items. (P> 0.05) 10. Stress related to treatment environment and nursing care was positively related of early adolescent and female and student patients. (P< 0.05) This group of hospitalized adolescents reported high level of stress related to treatment environment and nursing care, due to lack of consideration of normal growth and development and individual characteristics. The findings have important implications for the planning of effective, individualized, comprehensive nursing care of adolescents during hospitalization.

Historically, garments have been spontaneously made with human instinct in order to warm and decorate the body using textiles that have been made and used by various peoples in different cultures. Contemporary garments have been used as a means of warming as well as express individual personality and a desire to pursue beauty. They have a unique formativeness and a symbolic nature according to cultural phenomena that reflect a cultural outcome that expresses contemporary thinking and ideology as well as their aesthetic consciousness. This study globally promotes Chinese opera mask culture and proposes the possibility of creative thinking through the introduction of Chinese opera mask elements into contemporary fashion, expressing them as patchworks. In order to endow artistic value (required in contemporary fashion) this study creates works by analyzing and applying a formative sense seen in patchwork techniques and the characteristics of Chinese opera masks; in addition, it sought the possibility of new expressions in garment designs. The results obtained from the research involve the following. First, the introduction of the traditional patchwork technique to contemporary garments may be a dynamic theme of garment expression and exceed stereotypical ideas that enable the creation of designs attuned to the globalization era. Second, it was possible to pursue independent formativeness which is in harmony with a modern sense through the restructuring of the harmony of colors and practical characteristics found in patchworks. Third, it was possible to demonstrate their artistry and unique effect in the expression of contemporary garments by the expression of the analyzed results of characteristic patterns of Chinese opera masks with a patchwork technique in creating works. Results show that it is necessary to conduct research into a patchwork technique that applies diverse materials as a new method to develop contemporary garment design also as a creative design. In addition, if the analyzed results of the characteristic patterns of Chinese opera masks can be expressed with a patchwork technique, they may be able to exhibit a genuine effect along with the artistry of expression in contemporary garments; thereby, relevant follow-up research should be further continued.

Twenty Hanwoo steers (average body weight=440.8±32.4kg) were used to investigate the effects of fish oil supplementation on growth performance, fatty acid composition of longissimus muscle and carcass characteristics. The experiment was done with two treatment groups; FO-0, without fish oil and FO-3, supplemented with 3% fish oil. Total gain and average daily gain (ADG) of steers were similar between two groups. Fish oil supplementation had no effects on contents of protein, ether extract and ash in longissimus muscle. Contents of isoleucine and glycine in longissimus muscle were decreased by fish oil supplementation (p<0.05), but content of cystein was increased by fish oil supplementation (p<0.05). Fish oil supplementation decreased contents of myristic acid and eicosenoic acid in longissimus muscle (p<0.05), but increased contents of oleic acid and arachidonic acid in longissimus muscle (p<0.05). Contents of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in longissimus muscle were increased by fish oil supplementation p<0.05). Carcass weight, back fat thickness, rib-eye area, yield index and yield grade were similar between two groups. Meat color was improved by fish oil supplementation (p<0.05), Ratio of quality grade ‘1 or over’ increased by fish oil supplementation. Therefore, the present study indicating that fish oil supplementation had positive effects on content of oleic acids in relation to flavor of beef, contents of EPA and DHA in relation to human health and ratio of quality grade ‘1 or over’.

Utilization of synthetic benzyladenine (BA) for bean sprout production should be reduced or minimized because of elevating production cost and not ascertaining action mechanism to human body. The study was done to compare the effects of BA concentrations under different watering methods (overspraying or underwatering) on growth and morphological characteristics of mungbean sprouts. Seeds of cv. Zhong-Lu 1 were soaked for 5 hours in the solutions with different BA concentrations (0, 10, 20, 30, 40, 50 ppm) before 4 hour aeration, and then were cultured for 6 days by both watering systems. Their morphological characters, fresh and dry weights were measured. Regardless of watering methods, lateral roots were sharply dropped over 30 ppm BA concentrations, and hypocotyl, root and total lengths were shortened with increased BA concentrations although ratios of hypocotyl to root lengths and hypocotyl diameters were enlarged with their increment. Total fresh weights were increased up to 20 ppm in overspraying method but up to 30 ppm in underwatering method mainly due to increment of hypocotyl fresh weights. The sprouts were faster grown in overspraying method than in underwatering method because the former showed longer lengths of hypocotyl and root, and total fresh weights.

Various nerves from many areas of body can be used as a donor of autogenous nerve graft in the microneurosurgical repair of the oral and maxillofacial region. In the grafting procedure of nerve repair, the best results will be achieved with a maximum approximation of fascicular surface at both the porximal and the distal stumps. Therefore, appropriate selection of donor nerve will bring out the best results. The sural nerve has been used as one of the most popular donor nerve in the microneurosurgical repair of the oral and maxillofacial region. The authors examined the fascicular characteristics of the human sural nerve microscopically and compare this results with our previous report of the greater auricular nerve and that of the inferior alveolar nerve.

Foam block, popularized as the self-interior goods, is susceptible to fire since the main material is the polyethylene flammable synthetic resin. However, it is widely used in homes, offices, and multi-use facilities. In order to understand the fire characteristics of the foam block, two kinds of foam blocks sold in the market (non-fire retardant and fire retardant) were evaluated according to standard of KS F 5660-1 (Reaction to fire test). In addition, the hazard analysis of the gas generated by the combustion of the specimen was performed using the FTIR gas analyzer. The cone calorimeter test showed that the ignition and flame combustion of both two specimens were burned as soon as the radiant heat blocking device was removed, and it was confirmed that the flame could become a rapid propagation factor during the fire. The analysis of the combustion gas through the FTIR gas analyzer showed that both the carbon dioxide and carbon monoxide classified as the common combustion gases and the acrolein, ammonia, and hydrogen cyanide causing serious damage to the human body were detected substantially. This study showed that a foam block product has high ignitionability and generates toxic gases. Hence, it is urgently required to establish the standards used for properly classifying the combustion characteristics of the material on the basis of the use conditions of a foam block product and to prepare the standards on the purpose of use.
