The aim of this study is to analyze the relationship between fluctuations of a government subsidy and research outputs on the basic research field. An analysis of this study was conducted on basic research projects specifically on the field of information technology (IT) filed at university and Individual Research Programs of Korean ministry. Using various project characteristic variables, relationship between dependent variables and independent variables was controlled. To summarize results of a regression analysis, from looking at the correlation between fluctuations of a government subsidy and basic research outputs (weighted papers and patents), the result showed a positive relationship. The maximum effect of increased research funding projects on research outputs was 8 times greater than an effect of maintained funding projects. Moreover, the maximum effect of decreased research funding projects on research outputs was 4 times greater than an effect of maintained funding projects. Base on this result, we suggested implications from academic and practical aspects.

Naturally occurring substances which strongly scavenge peroxynitrite(ONOO-) are evaluated to be beneficial for cardiovascular, diabetic, hypercholesterolemic and obese disease. To search for bioactive substances with peroxynitritescavenging activity from the young leaves of Heracleum moellendorffii(Umbelliferae) used for a mountainous vegetable, the experiment on peroxynitrite-scavenging assay, phytochemical isolation and HPLC analysis were undertaken. Activity-guided fractionation led to the separation of astragalin and hyperoside which were identified by physicochemical and spectroscopic data. The $IC_{50}$ values of astragalin and hyperoside were shown as $5.80{\pm}0.62$ and $0.560{\pm}0.26\;{\mu}M$, respectively, in the assay. The HPLC analysis led to the quantitative determination of astragalin and hyperoside by $30.0{\pm}0.01$ and $17.0{\pm}0.02\;mg/g$ dried weight, respectively.

The effect of water extract composed of panax ginseng radix rubra, acanthopanacis cortex, and cordyceps (PAC) on diabetic animal models were investigated in two different diabetic animal models. FAC water extract significantly reduced the plasma glucose levels on day 30 as compared with the diabetic control group in $KKA^Y$ obese, hyperglycemic and hyperglycemic and hyperinsulinemic mice, and also reduced the plasma glucose levels as well as total cholesterol in multiple low dose (MLD) strep tozotocin-induced diabetic SD rats. PAC water extract also showed an inhibitory effect on reduction of body weight and on development of MLD STZ-induced diabetic state. Elevated kidney hypertrophy, which is a characteristic feature shown in early stage of diabetic nephropathy and calculated as the ratio of kidney mass (g) relative to the body weight (g), was also markedly improved in PAC water extract- treated group as compared to the diabetic control group. Taken together, these data suggest that PAC water extract may have a potential as a antidiabetic agent in type 2 diabetes mellitus.

The extracts of a lot of (different) plants were studied for inducing the secretion of growth hormone and IGF-1. In the cell test, it was found that the concentration of rat growth hormone was 88 - 99 ng/mL in a certain plant extract treatment group which was at least 6 times higher than the amount in control group. The concentration of IGF-1 in blood was 1,140ng/mL at 8 hours after the oral administration of YGF, which was remarkably much higher than that in control group. This meant that YGF maintained the level of IGF-1 secretion higher in the treated group. In addition, the increase of 6% in bone length was shown for the long-term oral administration of YGF. Thus, YGF seemed to affect significantly for inducing the secretion of IGF-1 which was essential for the physical growth and anti-aging.

Objectives : The purpose of this study is to report the clinical effect of Korean medical treatment, specifically Homnis Placenta pharmacopuncture, bee venom injection and Danggwisu-powder, on a patient suffering from a lateral malleolus avulsion fracture. Methods : A 63-year-old female patient suffering from right ankle pain due to lateral malleolus avulsion fracture was treated with Homnis Placenta pharmacopuncture, bee venom injection, and herbal medicine(Danggwisu-powder). from May 20th to June $16^{th}$ of 2015. The change in patientcondition was measured with the American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale, the verbal numerical rating scale, and via the ankle's range of motion. Results : After treatment, all obtained results showed improvement. The American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale increased from 18 to 71, the verbal numerical rating scale changed from 8 to 3, and the ankle's range of motion improved. Conclusions : This study suggests that Korean medical care focused on Homnis Placenta pharmacopuncture, bee venom injection and Danggwisu-powder can be effective to treat lateral malleolus avulsion fracture.

Objectives : This study was done to show the clinical effect of miniscalpel acupuncture treatment on osteoarthritis of the knee which is refractory to acupuncture treatment. Methods : A patient was treated with acupuncture for three weeks, non-treated(wash out period) for two weeks, and treated with miniscalpel acupuncture for three weeks. The effect of treatments were measured with Visual Analogue Scale(VAS), Range of Motion(ROM), Short form McGill pain questionnaire(SF-MPQ), Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC). Results : During the three weeks of acupuncture treatment, VAS, SF-MPQ and WOMAC improved, but after two weeks of the wash out period each score worsened. During the three weeks of miniscalpel acupuncture VAS, SF-MPQ, and WOMAC improved while ROM improved remarkably. Conclusion : These results suggest that miniscalpel acupuncture might be a therapeutic option for knee degenerative osteoarthritis patients who does not responded to acupuncture treatment.

The Document Management System(DMS) is a system which retrieves and manages library information efficiently. Since DMS manages the information using only one table, it does not need to provide join and view operations that spend high cost in traditional DBMS. In addition, DMs requires new operations because of their property. the operation has not been supported in existing DBMSs. In this paper we define a data language which represents the structure definition and process of data on the DMS. Especially we define Ranking and Proximity operation which is needed in Document Retrieval,. We also design and implement a query processor to process the query constructed with the data language. When the exiting query processors of relational DBMS are used as a query processor of DMS, they degrade the whole system performance. The proposed query processor not only overcomes such a problem but also supports new operation which is needed in DMS.

In this paper, we propose the index structure based on a vector approximation for efficiently supporting the similarity search of multi-dimensional data. The proposed index structure splits a region with the space partition method and allocates to the split region dynamic bits according to the distribution of data. Therefore, the index structure splits a region to the unoverlapped regions and can reduce the depth of the tree by storing the much region information of child nodes in a internal node. Our index structure represents the child node more exactly and provide the efficient search by representing the region information of the child node relatively using the region information of the parent node. We show that our proposed index structure is better than the existing index structure in various experiments. Experimental results show that our proposed index structure achieves about $40\%$ performance improvements on search performance over the existing method.

This paper presents the results of a case study of a dispute for the damage of the right to sunshine between B and W Apartment Complex in the N city. Recently a number of disputes for the right to sunshine increase in urban areas because the residents' demand for pleasant residential environment is getting stronger. In particular, problems related to sunshine, which were not recognized during the construction, have come up to the surface over time as people's concern over residential environment is growing. According to a recent interpretation of the right to sunshine in urban areas, moreover, there have been a series of legal decisions starting that damage of the right to sunshine to neighboring apartments must be indemnified for even if the violating apartment was designed and constructed legitimately according to relevant construction laws applied when the building was constructed. Thus this study examined the effects and the scope of damage on the right to sunshine through a case study in order to provide basic materials necessary to rope with related civil affairs.
