This study was carried out to establish an effective marketing strategy based on Importance-Performance Analysis (IPA) of rice-convenience foods. IPA is one of the most efficient and simple methods to evaluate product quality. Data were collected from 652 people (320 males and 332 females) and analyzed by SPSS 19.0. Subjects consumed rice-convenience foods as a snack substitute (19.3%), breakfast (20.7%), lunch (37.4%), dinner (15.2%), and late-night meal (7.4%). The purpose for consumption of rice-convenience foods were as follows: light meal (34.8%), lack of time to prepare meal (42.2%), favorite restaurant is not nearby (2.3%), save money (3.4%), and outdoor activities (9.7%). All attributes about rice-convenience foods were categorized into intrinsic property and extrinsic property. As a result of factor analysis, health, sensibility, and diversity factors were extracted from intrinsic property. In addition, dependence and appearance factors were drawn from extrinsic property. In analyzing the differences between importance and performance, there were significant differences; 16 items in the intrinsic property (P<0.01), and 10 items in the extrinsic property (P<0.001). The IPA matrix is composed of four quadrants, and each represents different strategies; the first, 'keep up the good work', the second, 'possible overkill', the third, 'low priority for management', and the fourth, 'concentrate management'. As a result, factors of rice-convenience foods positioned in the fourth quadrant were 'safety (from food additives, etc.)' and 'price' in the intrinsic property and 'nutrition label' and 'safety of packaging material' in the extrinsic property. They need to be improved immediately. In this study, rice-convenience food factors for continuous maintenance and concentrative improvement were compared by IPA. Based upon the results of this study, it is necessary to develop methods to make efficient use of limited resources and practical marketing strategies.

The social welfare service is expanding to different field as the social welfare budget is increasing. By this opportunity, it needs to make clear of the basis of argument that the necessity of development of korean government's support and aid by social policy should be worked. Welfare economics perspective, this study used by the operating expenditure in welfare facilities for the elderly old people to effect social benefits to be gained, in other words, business value analysis. Local elderly people, provide opportunities to participate in the economic activities of the family welfare services offered to attainment of the elderly welfare policy, and provide disease prevention and health promotion opportunities, to enhance the satisfaction of life, including a wide range of impact will cause. In this study, elderly people use the welfare facilities for the elderly when they get the benefits by applying the AHP analysis techniques operating value was calculated. Elderly Welfare Center operated by the result of applying P senior welfare center Case of the metropolitan area value was estimated 248.4 billion won. Contribute to the effects caused by the cost factor of the analysis was 23.1% of the total 57.3 billion won. Independence elements 57.6 billion (23.2%), the analysis of the therapeutic elements 133.4 billion (53.7%) of the net was. The result of the study anticipates the role of basic research material for the necessity of intervention, support, and aid by the Welfare facilities for the elderly field at this point in time where the welfare budget policy in terms of universal social service is reinforced, rather than the trend, until recently, of realizing the Elderly welfare budget and service as Consumption expenditure and consumable benefits and the function of performing the effect and evaluation in tentative action of social conflict.

In this study, we aimed to investigate the effects of dietary supplementation with fruiting body of Agaricus brasiliensis (AB) mushroom on the lipid profiles of serum and histological patterns of liver of high cholesterol-fed rats. Five-week-old, female Sprague-Dawley albino rats were divided into three groups of 8 rats each, including a normal control-diet (NC) group, a high-cholesterol diet (HC) group, and a group fed high-cholesterol diet supplemented with 5 % powder of Agaricus brasiliensis fruiting bodies (HC+AB). Total serum cholesterol, low density lipoprotein (LDL), and triglyceride (TG) concentrations in the HC+AB group were significantly reduced when compared with those in the HC group. Body weight in the HC+AB group was significantly lower than that in the HC group, whereas no adverse effects were observed on the levels of plasma albumin, creatinine, blood urea nitrogen, uric acid, glucose, and total protein. In the HC+AB group, liver enzyme activities related to liver function, such as GOT and GPT, presented values lower than those in the HC group and were very similar to the ones in the NC group. Excretion of total lipid and cholesterol in feces in the HC+AB group was significantly higher than that in the NC and HC groups, indicating that mushroom feeding inhibits the absorption of lipid cholesterol in the intestine. Liver histopathological analyses revealed that rats fed with HC diet developed fat liver disease, whereas only small amounts of fat were deposited in the livers of the HC+AB group. In conclusion, the results suggest that fruiting body powder of A. brasiliensis provides health benefits to high-cholesterol-fed rats by lowering body weight and the risk of atherogenic lipid profile.

In this study, the extracted phenolic compounds from 98 species of oriental herbal medicine were examined for biological activities to be used as functional resources. In particular, the anti-gout effect by xanthine oxidase (XOase) inhibition was determined using water and ethanol as extraction solvents because of their non-toxicity in the human body. The extracts of Chrysanthemum indicum L. (83.45%), Cuscuta chinensis (60.22%), Asiasarum sieboldi F. Maekawa (51.66%), Acorus gramineus (67.8%), Aconitum pseudo-laeve var. erectum (75.23%), Thuja orientalis (47.27%), Polygonum aviculare (53.98%), Carthami semen (63.99%), and Syzygium aromaticum (40.22%) showed relatively high XOase inhibitory activity. Chrysanthemum indicum L. was selected for its high XOase inhibitory activity. The biological compounds in Chrysanthemum indicum L. were identified to contain phenolics included in extracts of solids. Ultra-fine grind technology showed a higher extraction yield than normal grind and fine grind technology. Ethanol extracts showed relatively higher XOase inhibitory activity than water extracts. XOase inhibitory activity increased in a dependent manner as phenolic concentration increased. Therefore, ultra-fine grind technology was confirmed for use in increasing the extraction yield of XOase inhibitory compounds from Chrysanthemum indicum L.. Extracts from Chrysanthemum indicum L. are expected to be a useful functional resource for the prevention or treatment of gout.

This study was designed to investigates the effects of Korean pueraris radix water extract in Al(Aluminum) administered rats. Forty-eight male Sprague-Dawley rats weighing $100{\pm}10g$ were used for this experiment and divided into following 6 groups; control group, 3% pueraria radix in water extract group, 1000 and 2000ppm Al group, 1000 and 2000ppm Al group with 3% pueraria radix in water extract group. The Al administered rats were given 1000 and 2000 ppm of $Al_2(SO_4)_3$ disoved in the distilled water. The Al content in the rats tissue of Al administered group was lower than in the rats tissue of Al group with 3% pueraria radix in water extract group. Plasma levels of renin and aldosterone activity was increased by Al administration group, compared with 3% pueraria radix in water extract group and Al administred group. Glutamate oxaloacetate transaminase(GOT) and Glutamate pyruvate transaminase(GPT) were increased in Al-administered group and lower in the 3% extracts of pueraria radix in water extract group. Lactate dehydrogenase(LDH) was lower in the 3% extracts of pueraria radix-Al group than in the Al group. This results suggested that pueraria radix in water extract group has a lowering effects on the accumulation of Al and it is belived that the pueraria radix in extracted water group has some protective effects to Al administered in rats, but the mechanism of these effects was obscure.

The Korean Society of Law and Medicine has faithfully played the role of professional academic organizations last 20 years in terms of academic activities, accumulated achievements, diversity, professionalism, and influence on academic circles. The Korean Society of Law and Medicine and the Journal of Medical Law serve as a platform for academic information and exchange of opinions on medical law. Medical law began in the midst of increasing conflicts and disputes caused by medical malpractice and the enactment and legal coercion of medical care as pressure on medical workers. It tried to find a way to coexist with each other through the encounter and convergence of medicine and law. Medical criminal law extends from traditional crimes in the realm of life and body protection to bioethics violations caused by the development of biomedical technology, corruption and economic crime in the medical field. Medical law has evolved into a comprehensive legal area dealing with legal issues raised in medical treatment, healthcare, bioethics, and life sciences technology. On the legal side, medical law is not independent legal areas. It is overlapping with traditional law areas such as civil law, administrative law, criminal law, social law, civil and criminal procedure law. However, it is now established as a convergence study in medicine, bioethics, life science, as well as in various fields of law. It has become an area where collaboration is needed with the field of law, medicine, ethics, sociology and economics. Medical criminal law has undergone a dynamic development over the last two decades. The development of medicine and medical technology provides new and innovative methods of diagnosis and treatment. The achievements and risks of revolutionary developments in biotechnology, genetic engineering and medicine coexist. While there is a dazzling achievement that mankind has hoped for: combating disease and improving health, it also creates unwanted side effects and risks to humans. There is a need to reconsider ethical and legal principles. The discovery and development of patient identity and autonomy has changed the medical doctor-patient relationship. Furthermore, it was complicated by the triangle relationship of patients, medical doctors and insurance. Legal matters are also complicated. This is why the necessity of legislation is emerging. Criminal punishment provisions are also required. The Medical Law and Biomedical Law are systematically and coherently deformed as mosaic-based legislation that takes place whenever there are social issues, citizens' needs, and medical organizations' interests, rather than sufficient enactment and revision procedures. It needs a complete overhaul, and this is possible through interdisciplinary collaboration which is the strength of The Korean Society of Law and Medicine.

The purpose of present study was to introduce a multimetric approach, so called the Index of Biological Integrity (IBI) as a tool for evaluations of water environments. We used 11 metric systems for the IBI to evaluate stream conditions, based on the fish community, and modified 5 original metric attributes suggested by Karr (1981). Overall IBI values in Kap Stream averaged 36 (n = 5) and ranged 17${\sim}$49, indicating a 'fair condition' according to the modified criteria of Karr (1981) and U.S. EPA (1993). However, there were distinct differences in the IBI values among 5 study sites. The IBI values at sites 1, 2, and 3 were 49, 45, and 41, which indicated 'good${\sim}$excellent', 'good', and 'fair' condition, respectively, while values at sites 4 and 5 were 17 and 29, which indicated 'very poor' and 'poor', respectively. The minimum IBI at site 4 was probably due to continuous inputs of wastewater from wastewater disposal plants. The condition at site 4 resulted in predominance of tolerant species (50%), omnivore species (50%), and high abnormalies (43%). In the mean time, the IBI value at site 5, located near 5km downstream from the site 4, increased compared to that of site 4, and this seemed to be a result of recovery of water quality as the polluted water goes downward. We believe that present bioassessment methodology of IBI applied in this study may be used as a key tool to set up specific goals for stream restoration plans and dentify recovery levels of lotic ecosystems after restoration activities(i.e., prevention of point-source pollutant input, restoration of physical habitats, construction of riparian vegetation) as well as a biological measure diagnosing current stream conditions.

Purpose: The Rubus coreanus fruit (RF) is an important traditional medicinal herb having antioxidant, anti-inflammatory, and immunoregulatory properties. These activities are known to change dramatically, depending on maturity of the RF. It is presumed that change of functional components, such as flavonoids, tannins, phenolic acids, triterpenoids and organic acids in RF, affect the various bioactivities. This study aimed to confirm changes in the anti-melanogenic effects of RF based on maturity, and to identify the bioactive compounds responsible. Methods: The cell viability of mature RF (MRF) and immature RF (IRF) extracts was investigated using B16F10 cells. To compare the anti-melanogenic effect of MRF and IRF extracts, we first assessed the melanin content. High-performance liquid chromatography analysis was performed to evaluate changes in the level of ellagic acid according to maturity of the RF. In addition, tyrosinase inhibitory activity of both extracts was examined. Results: MRF and IRF extracts (50-200 ㎍/mL) do not affect the cell viability of B16F10 melanoma cells. IRF extract more effectively inhibited melanin synthesis than MRF extract. The content of ellagic acid in IRF extract was higher than that obtained in MRF extract. Furthermore, greater inhibition of tyrosinase activity was observed after exposure to IRF extract than MRF extract. A positive correlation was determined between ellagic acid content and tyrosinase inhibitory activity, and a negative correlation was obtained between ellagic acid content and melanin content. Taken together, our results indicate that ellagic acid is one of the major bioactive compounds of RF that imparts a whitening effect. Conclusion: Our results indicate that ellagic acid in MRF and IRF extracts affect the anti-melanogenesis effect through inhibition of tyrosinase activity. Therefore, the ellagic acid rich IRF has greater potential for application as a natural and functional cosmetic material.

This study qualitatively and quantitatively analyzed various carotenoids, L-ascorbic acid, and tocopherol and their anti-oxidant properties from four varieties (Special, Chelsea, Cupra, and Fiesta) and three different color stages [green (GP), yellow (YP) and red (RP)] of paprika harvested in Korea. Seven carotenoids were identified, mainly lutein in GP (Special: 4.65${\pm}$0.84 mg/kg fresh weight (fw)) and YP (Fiesta: 5.19${\pm}$0.05 mg/kg fw), and capsorubin (3.16${\pm}$0.35 mg/kg fw) and capsanthin (53.70${\pm}$6.23 mg/kg fw) in Special of RP. RP was the highest in total carotenoids, L-ascorbic acid, and ${\alpha}$-tocopherol contents, while GP was the highest in ${\gamma}$-tocopherol content. RP showed the strongest antioxidant activity ($IC_{50}$=62.40${\pm}$0.03 ${\mu}g/mL$ in an ABTS assay and 182.77${\pm}$31.74 ${\mu}g/mL$ in a DPPH assay). Paprika in different color stages has many phytochemicals even though they have different kinds of carotenoids. Therefore, dietary intake of paprika may be helpful for improving human health.
