Minerals, hydroxymethyfufural (HMF) and vitamins in native bee-honey (NBH) harvested from four different areas of Kangwon, korea were analyzed . Ash content of NBH varied from 0.26 to 0.50 % with the mean and standard deviation values of 0.32$\pm$ 0.17% and those of FBH varied from 0.15 to 0.58%(0.32$\pm$0.37) . Among analyzed minerals, the concentration of K,Ca, Mg, Fe and P except Na in NBH were found to be higher than those in FBH. The amounts of K and NA in NBH were 1200-3200ppm(2000 $\pm$770ppm) and 35-50ppm(38$\pm$6ppm), and those in FBH were 1100-3300ppm(1900$\pm$ 1700ppm) and 32-72ppm(49$\pm$17ppm), respectively. The mean value of Na to K ratio expressed as Na/Kx10$^3$ was 20$\pm$4 for the NBH and 41$\pm$25 for the FBH. HMF levels in NBH were 0.50$\pm$0.22mg% which was twice as much as those in FBH. Ascorbic acid and riboflavin in NBH were present at the range of 2.2-4.0mg% and 0.17-0.24mg% , respectively, of which were not significantly different from those obtained from the FBH.

This study examined the key factors that significantly improved the demand of multi-habitation. It determined the factors at the macroscopic level (or push factors) and the microscopic level (or pull factors). Focusing on a microscopic viewpoint, this study looked at the process of settlement through investigating 78 MH residents in the Seoul metropolitan area. The survey included the questions, such as who they are, how they prepared for moving, and how much they enjoyed their rural lives. In addition, any differences in this process were analyzed depending on respondents' characteristics. Major findings are as follows: First, general macro-level circumstances seemed supportive for the MH lifestyles. Second, six keywords were determined to represent the recent MH trends. They are "semi-sedentism, clustering, young people, female, money, and policy". Third, the distances between the original towns for native residents and new second-home towns for MH residents affected the interactions among them. However, these two groups had better relationships when the second-home towns were apart from the original towns. I then considered the need of a buffer zone between the two residential areas for MH residents. The conceptual difference between MH residents (i.e., semi-sedentism) and original rural residents (i.e., sedentism) might require certain types of buffer zones to continue good relationships among them.

Bupyong lead-silver mine is located at outskirt of Inchon, a harbor city on the Yellow Sea about 40 km due west of Seoul. The geology of the area is composed of gneisses of pre-Cambrian age, rhyolite of Jurassic to Cretaceous age which extruded over the gneisses and late Cretaceous granite. Small diabasic dike is observed only in the underground. The contact plane between overlying rhyolite and underlain gneiss is sinuous and generally pitches about $30^{\circ}{\sim}40^{\circ}$ toward east. Conjugate joints and fissures are well developed in the rhyolite striking generally north-southward. Three ore bodies are being exploited and three more are under prospecting. These ore bodies range from few tons of hundred thousand to million tons in reserve. These ore bodies occur exclusively in the rhyolite along joints as network and/or desseminated type. The lower limit of ore bodies is always delineated at about 20~30m above the gneiss which might be indicative of ore genesis that has not been clearly explained so far. Two hypothesis on ore genesis could, however, be considered: firstly lithologic difference in the rhyolite might be a manifestation of different flows along which ore solution ascended and replaced along joints; secondly diabasic dike has acted as ore bringer since the dike contains considerable amount of silver, lead and zine. Ore minerals are galena and native silver accompanied by pyrite, argentite, pyragyrite and magnetite. It is believed that pyritization took place in advance to main mineralization, and ore deposit is classified as meso- to epi-thermal type.

Effects of catecholamines and the site of receptor of catecholamines were investigated in the longitudinal muscle of the rumen. In order to this experiment, specimens were obtained from 35 Korean Native Cattles, 2-3 years old, in the Kwang-ju area slaughterhouse. Longitudinal muscle strips of rumen were made from sample, and then measured the isometric contraction with physiograph in $37{^{\circ}C}$ organ bath. The results were summarized as follows. 1. 30% of all strips showed rhythmic contraction after short incubation time. 2. Relaxation produced by catecholamines in this preparations increased in a dose-dependant manner. 3. Isoproterenol(${\beta}$-agonist) caused relaxation, but phenylephrine(${\alpha}_1$-agonist) and xylazine(${\alpha}_2$-agonist) were unaffected. 4. The relaxation induced by epinephrine and norepinephrine were not affected by phentolamine(${\alpha}$-blocker) and prazosin(${\alpha}_1$-blocker), yohimbine(${\alpha}_2$-blocker). But propranolol(${\beta}$-antagonist) abolished the effect of catecholamines on relaxation. 5. It is concluded that catecholamines produced relaxation in the longitudinal muscle of rumen via the ${\beta}$-adrenoceptor.

Effects of histamine on the ruminal smooth muscle motility of cattle were investigated in the longitudinal and circular smooth muscle strips. In order to these experiments, specimens were obtained from 35 korean native cattles, 3-4 years old, in Kwang-ju area slaughterhouse. Smooth muscle strips of rumen were made from sample, and then measured the isometric contraction with physiograph in $37{^{\circ}C}$ organ bath. The results were as follows : 1. Histamine caused two different types of response(a contraction or a relaxation) on the smooth muscle of cattle rumen. These responses increased in dose dependant manner. 2. Pyrilamine($H_1$-receptor antagonist) completely blocked contraction in all the preparation and converted the response into relaxation. 3. Cimetidine($H_2$-receptor antagonist) completely blocked relaxation in all the preparation and converted the response into contraction. 4. The contraction induced by histamine($10^{-3}M$) was not Mocked by cholinergic, adrenergic blocker or hexamethonium. 5. The contraction induced by histamine($10^{-3}M$) was markedly inhibited in the $Ca^{2+}$ free(or EDTA 2Na) Kreb's solution and by verapamil.

New chords formation of mitral valve using expended-polytetrafluoroethylene sutures was performed in six patients with mitral regurgitation (MR) from April, 1994 to March, 1995. There were 3 men and 3 women whose mean age was 65 years, ranged from 55 to 75. A double-armed pledget suture was passed through the lateral portion of papillary muscle head and tied. Each arm of the suture was brought up to the free margin of the leaflet and passed through the area where the native chorda was attached. At leaflet surface, one more weaving was made. fter the lengths of the two arms were adjusted, the ends were tied. There were no operative deaths. Patients have been followed up from 2 to 13 months, mean 8. Echocardiographic sutudies were performed at 10 days after operation and revealed normal mitral valve function in all patients.

This study was conducted in order to better understand the local and specialty foods of the Yeong-ju region. This study provides basic data for new menu development and commercialization. The results of 384 surveys, which were conducted to determine traditional rice cake production methods and their traits, were analyzed. Samgyetang was ranked top in the survey on recognition, public interest, and frequency of the local foods. Dakjuk was ranked second, followed by Baechujeon and Bopguk, in order. The levels of recognition and preference of specialty foods were in the order of hasuo, peach, apple, and meat. Among the answers in the survey on the popularization and commercialization of local foods, changing of the cooking style for younger generations' taste was considered to be the most important. Holding events to promote regional specialty foods and initiate the public to traditional cooking styles were listed sequentially by importance. The survey results show that promotion of local foods through education, and as well as incorporation of new ingredients are both highly effective ways to commercialize local foods for tourism. The results also indicate that taste, nutrition, and appearance of food should be considered in order to improve quality.

In this study, the contents of dust and associated heavy metals on roadside plants were investigated to assess their foliar transfer. The study was conducted at six different locations (four roadside and two industrial) near an industrial area in Bilaspur (Chhattisgarh), India. Six metals (Fe, Mn, Pb, Cu, Cr, and Cd) were examined in this study. The concentrations of heavy metals in foliar dust were found to be in the order of Fe>Mn>Pb>Cu>Cr>Cd. However, this relative order changed in the case of leaf concentrations to Fe>Mn>Cd>Cu>Pb>Cr. The metal concentrations in the dust and leaves can be attributed mainly to industrial and vehicular emissions. In contrast to other metals, Cd showed significant accumulation in the leaves compared to the respective dust samples. This study showed different patterns in the distributions of heavy metals between the dust deposited on the leaves and the metal accumulated in the leaves. These results suggest that the dust retention and heavy metal accumulation in native plant species should be explored in an attempt to manage these hazardous metallic elements.

In order to develop the effective methods of electroacupuncture anesthesia to bovine species. eight animals of Korean native cow, which are healthy and have ordinary perception response. were examined to study on the acupuncture prescription. In the present study, six kinds of acupuncture prescription methods were applied with four kinds of meridian points which consist of Sam Yang Rack, Keuk Moon, Boo Yang and Sam Eum Kyo. The results are summarized as follows. 1. All kinds of methods applied here were simple in needling technique but considerably effective on analgesia. It was also confirmed that the methods could be applied to the all clinical signs, because these were not depended to vary on the position of operation area and the body restrain. 2. The results, which were obtained by applying to all meridian points at both legs selected by diagonal lines(e. g., right foreleg and left hind leg, and vice versa) and to all meridian points at the all legs, were revealed the same analgesia effect. However, the result applied to meridian points at one side of body did not show the good effect for analgesia. 3. When the acupuncture prescription was applied to Sam Yang Rack and Keuk Moon at both forelegs, and Boo Yang and Sam Eum Kyo at both hind-legs, the good effects of regional analgesia appeared at the anterior body and both forelegs, and the posterior body and both hind-legs, respectivery. 4. There was no sognificant difference in changing biochemical pictures of blood and serum during the experiment.

Zoysiagrass has been used in Korea as a native grass. Informations on distributions, classifications, breeding efforts and outputs, current production and uses of zoysiagrasses in Korea are summarized. During past a few decades, collection of naturally growing zoysiagrass ecotypes has been continued, followed by evaluation, selection and cross-pollination. Classification efforts using important morphological, biochemical traits and DNA polymorphisms resulted in the several suggestions of grouping zoysiagrass species and varieties. Zoysia japonica consistently form separate group, while Zoysia sinica and Zoysia macrostackya have been separately or inter-mixed. Z. matrella with some variations frequently grouped separately but with some similarity with Z. tenuifolia, which was recently renamed as Z. pacifica. Hybrid types of zoysiagrasses were frequently found in Korea. New varieties such as 'Kunhee' and 'Green Ever' etc. were bred by ecotype selections, while 'Senock', 'Semil', 'Millock' were bred through pollination. Molecular approaches were also used to introduce beneficial genes into zoysiagrasses with no practical outputs by legal regulations. Currently popular varieties are inter-specific hybrid types such as 'Anyang' and other local zoysiagrasses as well as common zoysiagrass (Zoysia japonica) Production area in Korea was estimated as 2,947 ha with increasing problems of mixed or contaminated species and varieties.
