  • The terrestrial UV flux rapidly increased in late spring, as measured by the chemical actinometry at two elevations (near sea level and 1,100m above sea level) on Jeju Island. More intense UV fluxes were observed at higher altitudes. Any harmful effects of solar UV-B on the growth of soybean were not detected in UV-B-exclusion experiment. To ascertain the effect of UV radiation on vegetative growth, intact (㏖ wt 124000) and large (${\sim}120000$) phytochromes were irradiated with UV-B radiation. In intact phytochrome, the Pfr form accounts for 60% of the total phytochrome under stationary state conditions, whereas it accounts for 50% in large phytochrome. Calculated quantum yields for the forward and the backward phototransformations of phytochrome by UV were ${\phi}r=0.016$ and ${\phi}fr=0.010$ in intact phytochrome, and ${\phi}r={\phi}fr=0.012$ in large phytochrome, respectively.

  • This study was conducted to investigate the effect of Zn and Fe levels on lipid metabolism and micromineral contents in high fat diet-induced obese rats. Male sprague-dawley rats weighing approximately 100g were fed a normal or high fat diet. After 10 weeks high fat diet, rats were fed different levels of Zn and Fe. Serum triacyglycerol and HDL-cholesterol were affected to Zn and Fe levels in normal group. The micromineral (Zn, Fe, Cu, Mn) contents in liver were significantly different in high fat diet group by Zn intake levels and in normal diet group by Fe intake levels. However, micromineral contents in kidneys were not affected to different levels of Fe in both obese and normal rats. There were no differences in spleens of obese rats fed high fat diet according to Zn and Fe intake levels. But in normal group, Mn content of spleen were exclusively affected to Zn levels.

  • Thermal maturation and diagenesis of the Gyeongsang Supergroup in the Euiseong area are studied by means of organic geochemical techniques and illite crystallinity. Black mudrocks of the Singdong Group contain organic matter of $0.5{\~}2{\%}$ derived from higher plants, being compared to type Ⅲ. Thermal maturity of organic matter reached dry gas generation phase. Tmax by Rock Eval pyrolysis varies between $578^{\circ}C$ and $593^{\circ}C$ regardless of stratigraphic position and localities, and vitrinite reflectance is about 2.9 and $3{\~}4{\%}Ro$ in the Jinju and the Nagdong Formations, respectively. Vitrinite reflectance measurements indicate that the maturation is mainly due to burial and partly to be affected by post-depositional intrusions. Illite crystallinity values from the Nagdong, Hasandong, Jiniu Formations and part of the Iljig Formation are plotted around the boundary between diagenesis and anchizone, indicating dry gas generation stage. However, the values are not dependent on stratigraphic position. The values from the Iljig, Hupyeongdong, Geomgog, and Sagog Formations fall into the range of anchizone, probably resulted from the post-depositional intrusions which occur locally. Both organic geochemical and illite crystallinity data indicate thermal maturation stage of dry gas generation. Diagenesis of the Gyeongsang strata is mostly controlled by burial, and partly affected by post-depositional intrusions. Paleotemperature of the Sindong Group is estimated at around $200^{\circ}C$ on the basis of illite crystallinity.

  • Jeongeuihyanggyo(旌義鄕校) is a kind of traditional, Confucian cultural landscapes that is located in Jeju special self-governing province. Its historical background illustrates that the first erection was started at Goseong-li of Seongsan-eup(城山邑 古城里) at Taejong(太宗) of 16 years(1417) and it moved to the west gate of Hyunseong(縣城) at Heojong(憲宗) of 15 years,(1849) Joseon. The aim at this study is to reveal characters of these Confucian Spatial Composition and Order, which are valuable resources that can be created into the cultural contents. The results demonstrate the characters of the Confucian cultural landscape as followings; the changing process of new building and its relocation, the utilization of antique maps in location interpretation of Jeongeuihyanggyo, Confucian symbolic elements of it, the spatial compositions and layouts of its buildings, physical structures, main buildings and their characters, locational points of topographic profile, changes of axial line at Daeseongjeon(大成殿), the D/H ratio of its courts. This study can show that Jeongeuihyanggyo is a case for realizing the Confucian reformation to enhance Seongeup Hyun's education standard considering the locality of the site which is an isolated island like Jejudo(濟州島). The author can see that the example of Confucian space is applied to various layout techniques, both horizontally and vertically, in a limited space condition of being in the castle. Therefore, it is necessary to revive this point so that it can utilize unique Confucian cultural landscape possessed only by Jeongeuihyanggyo.

  • In order to determine the possibility that Chrysanthemum indicum L. cultured with Lactococcus lactis (CILL) is a material for obesity suppression food, the body weight, body fat mass, and T cells were determined in C57BL/6 mice induced by a high fat diet. The CILL (25.15±2.44 g) demonstrated weight loss from week 4 onward and maintained a low weight gain from week 1 to week 8 (1.00±0.53 g). The 8-week body weight (30.38±4.17 g) indicated loss of 13.15% when compared to the HFD (60% high fat diet, 34.99±2.09 g). Fat mass decreased to 10.3022±2.8813 g, and the absolute liver weight decreased relative to that in the HFD. CD4+ T cells were 4.84±1.33%, CD8+ T cells 7.02±2.26%, and CD4+CD8+ T cells 1.46±0.81%, which were all higher than those in the HFD. As a result, CILL can be used as a material for preventing obesity as an effective measure toward reducing weight when consumed orally.

  • The term "Collaborative medical care" commonly used in South Korea refers to the case where doctors from different medical departments work together to treat a patient within the same medical institution. Therefore, "Collaborative medical care" represents the aspect of a medical team where various medical professionals collaborate based on their expertise to treat patients. Additionally, doctors from different specialties within the medical team engage in horizontal division of labor at an equal status, distributing legal responsibilities according to the principles of division of labor. The Supreme Court also acknowledges cases where multiple doctors collectively provide medical treatment through division of labor or collaboration and states that the doctor who initially attended to the patient must accurately inform the subsequent attending doctor about the patient's condition to enable appropriate measures. In medical institutions with multiple specialties, when doctors from different specialties collaborate to provide medical treatment, the doctor who attended to the patient initially must decide whether collaboration is necessary based on the patient's condition. Subsequently, they must inform the doctor from the relevant specialty about the patient's condition accurately to facilitate appropriate actions. The successor doctor who participates in collaborative medical care must actively communicate relevant treatment information related to the patient's condition with the predecessor doctor who requested collaboration, exchange opinions, and do so until the patient's treatment concludes. However, the determination of the necessity of collaborative medical care should be based on the patient's condition at the time, and it cannot be asserted that collaborative medical care is mandatory in all cases. Whether there is negligence in the decision about the necessity of collaboration will be assessed based on the legal principles of a doctor's duty of medical care.

  • The present study was investigated to evaluate on the health improving effect of Kochujang (Fermented Korean hot pepper paste), which was famous as Korean traditional healthy food among foreigners as it was served together with Bibimbap. For comparison, observation was made on the experimental animals (Sprague-Dawley rat) as breeding during 5 weeks, which were divided three groups as into the control groups (N-group) fed with normal feed only and high cholesterol feed only (H-group) and the K-group with combined diet of normal feed and Kochujang extracts (Water soluble complex materials). The most outstanding result was found as the definite fatty liver lesions found from all (100%) of the rats of the H-group at the abdominal opening examination. On the other hand, there was any finding on fatty liver lesions in the N-group as well as the K-group. Therefore, it was more than enough to identify the hypolipidemic effect by visual finding only. Furthermore, from the results of blood plasma analysis from SD-rats fed with Kochujang extract (K-group), more prominent differential findings were found, the value of HDL-cholesterol, which was good for preventing the arteriosclerosis, was more or less higher than that of H-groups. But the level of LDL-cholesterol, which was one of the hazardous agents of hyperlipidemia and arteriosclerosis, was more significantly reduced to the level even lower than that of N-group, based on the statistical analysis, in especial. According to the present results, we could find that the unidentified Korean traditional Kochujang-derived complex components had expressed both the positive health improving effects and hypolipidemic effects on the SD-rat.

  • In Oriental Medicine, hyperlipidemia is considered as the phlegm stagnancy(痰飮) and blood stasis(瘀血). Typhae Pollen helps remove blood stasis and hemorrhage and it also has an effect of relieving pains caused by blood stasis. The purpose of this study is to investigate the curative effects of Typhae Pollen on diet-induced hyperlipidemia in rats. Thirty-two rats were divided into normal, control and treated group. Control and treated group were fed with 1.5% cholesterol diet during 4 weeks, and fed with normal diet during next 4 weeks. Treated group was also administrated with extract of Typhae Pollen during last 4 weeks. Blood samples were collected from each of animals at 4, 6 and 8weeks, and used for the blood chemical analysis. Animals were sacrificed at 8 weeks, and chemical analysis was performed on the collected liver samples. The serum total cholesterol(47.82±2.03㎎/㎗), LDL-cholesterol(11.09±1.27㎎/㎗), HDL-cholesterol (19.64±1.23㎎/㎗), triglyceride(85.09±3.48㎎/㎗) values of treated group were significantly decreased compared with the serum total cholesterol(73.73±5.34㎎/㎗), LDL-cholesterol(22.09±3.09㎎/㎗), HDL-cholesterol(25.18±1.45㎎/㎗l), triglyceride(124.27±6.72㎎/㎗) values of control group at 8weeks. The liver total cholesterol and triglyceride values of treated group show no statistically significant differency compared with those values of control group. On the basis of these results, it is confirmed that Typhae Pollen has the curative effects on the hyperlipidemia in rats induced by hyper-cholesterol diets.

  • Today the issue of deterioration of industrial complexes that are located close to life space of residents has been raised as a cause of threats to the safety of local communities. In this study, in order to improve the current risk analysis and scope of community notification, simulated threat zones were comparatively analyzed by utilizing the threat zones of alternative accident scenarios and modes of seasonal weather, and the area with a high probability of damage upon the leakage of toxic substances was predicted by examining wind directions observed at each time slot for each season. In addition, limit evacuation time and minimum separation distance to minimize casualties were suggested, and a proposal to enable more reasonable safety measures for on-site workers and nearby residents made by reviewing the risk management plan currently utilized for emergency response.

  • In Internet of Things (IoT) environments, devices or sensors everywhere can automatically collect data without the individual awareness, further combine and share data using ubiquitous network, and thus the development of IoT raises new challenges in respect of personal data protection and privacy. This study aims to identify main issues related to data protection in the IoT and propose adequate measures. We analyzed the types of personal data controllers and processors in IoT and figured out the issues regarding the processing of personal data and the rights to privacy of data subject. Accordingly, we suggested the institutional ways (e.g., establishment of user-friendly notice and flexible consent system, re-identification risk monitoring system, data protection in cross-border transfer, and user education) to improve the situation of personal data protection in IoT and finally proposed the improvement tasks to carry out first based on the degree of urgency and importance.
