This study was conducted to determine the seed dormancy types of Sambucus racemosa subsp. pendula Nakai and S. williamsii Hance. Low temperature stratification (1, 2, 3, 4 months) and GA3 treatment (1,000 mg/L) were performed on seeds to determine the type of seed dormancy. After the treatment, seeds were placed on a petri dish at 25℃ under light conditions. The germination rate and mean germination time were investigated. Results showed that cold stratification was effective in breaking the dormant state of the seed in both species. In the low temperature stratification treatment, the seed germination performance was improved as the treatment period was prolonged. Gibberellin treatment was effective in breaking the dormant state of S. racemosa subsp. pendula without low temperature stratification. However, S. williamsii did not break the dormant state of the seed by gibberellin treatment without low temperature stratification treatment. In the gibberellin treatment, germination performance was improved according to the low temperature stratification treatment period. As a result of this study, the seeds of S. williamsii have both an intermediate complex and a deep complex morphophysiological dormancy (MPD). In comparison, it was found that the S. racemosa subsp. pendula had intermediate composite MPD.

Nine Holstein cows in mid lactation period were utilized to examine the effect of recombinant bovine somatotropin (BST) of tow companies (Company A, Company B) on milk production and milk composition under the feeding conditions of Korea. Treatments were 0 (Control), 25 mg BST/day from company A (BST A) and 25 mg BST/day from company B (BST B) injected subcutaneously, once daily beginning at $200{\pm}20$ days postpartum and continuing for 28 days. Cows were fed ad libitum a total mixed diet throughout the experimental period. BST treatments increased average 4% fat corrected milk yields and milk energy output over the 28-day treatment period. However, no differences were observed in dry matter intake, gross efficiency, energy intake and percent milk energy. Although there was a tendency for increased milk fat percent, there were no differences in milk composition and yields of major milk components except for milk fat yield with BST injection. Somatic cells of all groups were also characteristic of a well managed herd. Neither mean body condition score nor body weight was significantly (p <0.05) changed before and during BST treatment. BST concentration in milk remained in the range of control animals throughout the experimental period of BST treatment. Results indicate that short-term injection of recombinant bovine somatotropin from two companies to lactating dairy cow resulted in similar increased in milk yield without alteration of major milk components or feed intake.

In the first of two experiments, chemical composition (Ash, CP and CF contents), nutritive value (in vitro organic matter disappearance "lVOMD" and energy content "ME") and nitrogen retention of chopped date fronds (CDF) as affected by chemical treatment (CT) and storage duration (SD) were investigated. The experimental design was a completely randomized block, arranged in a $3{\times}4$ factorial, with 3 (CT) and 4 (SD) as the main factors using 2 replications / treatment. Three chemical treatments, were used : Control (With zero or no chemical treatment); treatment with 4% urea solution (w /w) and treatment with 4% urea + Date syrup extract (DS). The 4 (SD) were: Control (immediately after opening - without any storage or zero time storage); one month storage period; two months storage period and three months storage period. Both (CT) and (SD) had significant effects (p < 0.05) on CP and ash contents of the CDF, however there were no significant effects (p > 0.05) due to (CT) and (SD) on CF and nutritive value. High retention value (> 80%) for nitrogen was reported for the treated CDF, immediately after opening the incubated material (zero SD). However, nitrogen retention decreased with increasing (SD) to 67% after one month (SD) but tended to stay at a fairly constant level of 67% until 3 months of storage. In experiment 2, the feeding value of treated CDF was evaluated in comparison to Rhodes grass hay, using growing goats and sheep. A $4{\times}2$ factorial design was used (Four roughage sources were used : Rhodes grass hay, untreated CDF, urea-treated CDF and CDF treated with urea + DS with sheep and goats as two animal species, using three animals / treatment). Untreated CDF had a similar feeding value to Rhodes grass hay. However treatment of CDF with urea alone or with urea + DS depressed animal performance of both goats and sheep, apparently due to depression of feed intake (appetite). Feeding untreated CDF decreased feeding cost by 29% and cost/kg gain by 23%. CDF showed a good potential as a cheap local roughage and emergency feed for ruminants in the Sultanate.

PURPOSE: This study seeks to examine the awareness and need of home visiting physical therapy among physical therapist in Gwangju and Jeonnam province. METHODS: Survey was conducted during the continuing education on physical therapist held in Gwangju in 2015 with 297 participants. The survey questionnaire consisted of 12 questions on the characteristics of physical therapists, 8 questions regarding the awareness of home visiting physical therapy, and 7 questions on need. RESULTS: Significant differences were found regarding service period, according to categories of the inconvenience associated with commuting to/from hospitals, long-term treatment for patients, high quality treatment with intensive care, treatment at a time of patients' choosing. The category of hospital fees reduced due to early discharge from the hospital also saw significant differences, depending on respondents' marital status, dependent family, and service period. Providing treatment without causing discomfort to patients in front of others also saw significant differences according to physical therapist career period. Home visiting physical therapy is easier for family members to take care of patients also saw significant differences according to education and physical therapist career period. CONCLUSION: Survey indicates that physical therapist province feel the need for home visiting physical therapy in many respects. However, since as many as half of the surveyed physical therapists have only heard of home visiting physical therapy or are have no awareness of the this form of treatment, it appears that there is a need to raise awareness of home visiting physical therapy among physical therapist and introduce appropriate policies.

I have felt seriously a desire to study and analyse the medicine of the period of the Three Kingdoms when I thought and studied the ancient medical history. Therefore in Chapter II I inquired into the background of Politico-social and the currency of thought. In the Chapter III inquired into the system of Medical politics in the period of the Three Kingdoms. In the Chapter IV inquired into the general view of the period of the Three Kingdoms. In the Chapter V inquired into the writings of Medicine and Doctors. From this study, I reached at following-conclusions. 1. The Three Kingdoms are politically opposed to each other, but socialo culturaly cooperated, connected each other to import the technique and thought which developed in China, so generally their system and life pattern are alike. 2. On the system of medical politcics Goguryeo(高句麗) had the system of court phisician, Baek jeo(百濟) had medical doctor and collector in the Ministry of Drug which took charge of teaching and medical treatment and specially had spellchanting doctor who treat epidermic and psychological diease untreated with herb and acupuncture, Shilla(新羅) had the system of Yak chun which was charge of teaching and treatment, and had the Chimbang(針房) which assist doctor in the system of Yagchun(藥典制度). 3. The medical interchange with China made the Three Kingdoms to import the medical books. So the theory of medicine was systematized and the art of treatment developed. In the aspect of Herb the Three Kingdoms and China actively exchange their own district product. 4. The medicine of Three Kingdoms accommodated Yin Yang Ohang theory(陰陽五行說), the theory of body compose with four element(四大 : 地水火風) and the theory of life cultivation and breathing(導引養生說) with Therefore in many aspect of oriental medicine basic theory and treatment would improved. 5. The epidermic diease occurred in period of Three Kingdoms, is represented Yeok(疫), that is after all Ohn Diease(溫病), and epidermic diease, is relfected by earthquake, heavy rain, terrible droughty and eclipse of sun. The treatment of this diease did not developed in that time, we presume that there are many persons killed. 6. As the record of five starr(五星), comet(彗星) and eclipse of sun was showed, the astronomy of oriental medicine in the Three Kingdoms was high level and it became the mothers womb of Korean astronomy. 7. The medicine of the Three Kingdoms, concreted with Chinese medicine and their own ancient one, was reflect on Japanese medicine to improve the medical theory and treatment. 8. The Three Kingdoms peculiarly published Korea Nosabang(高麗老師方) Baekjyeo Shinjipbang(百濟新集方), so this independent medicine reflected on the development of natural hurb(鄕約) of the period of Korea(高麗).

Objectives : The aim of this study was to compare improvement according to the hospitalization period of patients with neck pain as a result of traffic accidents. Methods : Patients of 59 cases with neck pain induced by traffic accidents were investigated. Based on their hospitalization period, 59 subjects were divided into two groups: A group with a shorter hospitalization period and B group with a longer hospitalization period. Each group was treated by the same therapies including acupuncture, pharmacopuncture, and herbal medicine. To compare the treatment effects of the two groups, the Visual Analog Scale(VAS) was used. Statistical analysis between two groups was assessed using the chi-square test, Mann-Whitney U Test and paired t-test through the SPSS 12.0 Windows program. Results : After admission treatment, both A and B group showed a significant decrease in their VAS scores. In addition, B group, of which the hospitalization period was longer than A group, showed a significant improvement in comparison to A group in its VAS score. Conclusion : This study suggests that pain control is more effectively achieved in patients that received more than 8 days of admission treatment compared to those who received less than 7 days of admission treatment.

The aim of this study was to determine the appropriate stockpiling methods for revegetation by comparing the germination status of seed banks before and after preservation for 2 years. Soil temperature in stockpiled topsoil was higher in open treatment and at 1.5 m, whereas soil water content was maintained at lower levels (14.06-19.08%), than those in the control group. The seed banks in stockpiled topsoil had 48 species and 1,559 individuals, among which perennials showed the highest number in terms of life forms, whereas Compositae and Gramineae were dominant in terms of families. Based on seed bank type, persistent seed banks had the highest number of species, while transient seed banks had the highest number of individuals. By stockpiling period, the number of species in the seed bank started to increase after 24 months, while the number of individuals began increasing after 12 months and exceeded that of the control group after 24 months. Regarding the treatment of stockpiling methods, the number of species and individuals in open treatment were closer to those of the control group. When analyzed by height, the number of species and individuals were higher at 0 m, but still lower than those of the control group. A multivariate analysis of variance (MANOVA ) showed that the optimal combination was obtained in open treatment and the number of individuals increased with the lengthening of the stockpiling period.

The electrocatalytic activities and surface roughness of indium-tin-oxide (ITO) electrodes have been investigated after thermal treatment at 100, 150, or $200^{\circ}C$ for 30 min, 2 h, or 8 h. To check electrocatalytic activities, the electrochemical behavior of four electroactive species (p-hydroquinone, $Ru(NH_3){_6}^{3+}$, ferrocenemethanol, and $Fe(CN){_6}^{4-}$) has been measured. The electron transfer rate for p-hydroquinone oxidation and ferrocenemethanol oxidation increases with increasing the incubation temperature and the incubation period of time, but the rate for $Ru(NH_3){_6}^{3+}$ is similar irrespective of the incubation temperature and period because $Ru(NH_3){_6}^{3+}$ undergoes a fast outer-sphere reaction. Overall, the electrocatalytic activities of ITO electrodes increase with increasing the incubation temperature and period. The surface roughness of ITO electrodes increases with increasing the incubation temperature, and the thermal treatment generates many towering pillars as high as several tens of nanometer.
