The Proximity Service, which is one of the most popular network capacity improvement methods, uses the frequency reuse in order to increase the frequency efficiency. As a result, inter-cell interference between cellular and proximity service users occurs at a cell edge. In this paper, we proposed a mitigation scheme for inter-cell interference, where we suggested a new function of and eNB with ProSe function exchanging information about ProSe parameters and ProSe user equipment with neighboring cells via the X2 interface. As the first step, the resource which did not cause the inter-cell interference problem were pre-allocated through the frequency sensing in the ProSe direct discovery. As the next step, the inter-cell interference problem was solved by reallocating appropriate resources based on the ProSe application code, the ProSe application QoS, the ProSe application ID and validity timer in ProSe direct communication.

도메인 기반 단백질 상호작용 예측 기법은 지난 몇 년 동안 활발히 연구되어 왔다. 도메인 기반 접근 방법 중에서도 도메인 조합 기반 단백질 상호작용 가능성 순위 부여 기법은 예측 정확도면에서 다른 기법보다 월등한 결과를 보여주고 있다. 그러나 학습 집단을 사용하는 특징 때문에 전체 도메인 정보를 이용할 수 없는 단점이 있다. 또한, 이 시스템은 도메인 정보가 부족하여 다른 기능을 하는 단백질이라도 같은 도메인 정보를 보여주기 때문에 예측 시스템의 결점을 드러내고 있다. 도메인 조합 기반 단백질 상호작용 가능성 순위 부여 기법은 InterPro 데이터베이스의 도메인 정보를 기반으로 사용한다. InterProScan은 InterPro의 여러 멤버 데이터베이스의 정보를 기반으로 Sequence 분석을 하는 소프트웨어로써 검색 후 단계에서 찾아낸 결과들을 e-value를 기반으로 여과한다. 본 논문에서는 제시된 e-value를 조정 방법을 사용함으로써 단백질 내 도메인 패턴의 다양화와 기존 도메인 정보가 없던 단백질의 도메인을 새롭게 발견할 수 있으나 접근 방식의 한계가 존재함을 확인할 수 있었다.

Recently, high-throughput technologies such as the two-hybrid system, protein chip, Mass Spectrometry, and the phage display have furnished a lot of data on protein-protein interactions (PPIs), but the data has not been accurate so far and the quantity has also been limited. In this respect, computational techniques for the prediction and validation of PPIs have been developed. However, existing computational methods do not take into account the fact that a PPI is actually originated from the interactions of domains that each protein contains. So, in this work, the information on domain modules of individual proteins has been employed in order to find out the protein interaction relationship. The system developed here, WASPI (Web-based Assistant System for Protein-protein interaction Inference), has been implemented to provide many functional insights into the protein interactions and their domains. To achieve those objectives, several preprocessing steps have been taken. First, the domain module information of interacting proteins was extracted by taking advantage of the InterPro database, which includes protein families, domains, and functional sites. The InterProScan program was used in this preprocess. Second, the homology comparison with the GO (Gene Ontology) and COG (Clusters of Orthologous Groups) with an E-value of $10^{-5}$, $10^{-3}$ respectively, was employed to obtain the information on the function and annotation of each interacting protein of a secondary PPI database in the WASPI. The BLAST program was utilized for the homology comparison.

Human follicular fluid (HFF) is the in vivo microenvironment for oocyte maturation and includes a variety of proteins that could be involved in oocyte development and fertilization. We therefore used a proteomic approach to identify new HFF proteins. HFF from mature human follicles was obtained from five women following oocyte collection for in vitro fertilization (IVF). Ethanol-precipitated HFF run on two-dimensional gel electrophoresis (2DE) produced approximately 250 Coomassie brilliant blue-stained spots, 64 of which were identified using matrix-assisted laser desorption/ionization-mass spectrometry (MALDIMS). In this study, several proteins including complement factor H, inter-${\alpha}$ (globulin) inhibitor H4, inter-${\alpha}$-trypsin inhibitor heavy chain H4 precursor, human zinc-${\alpha}$-2-glycoprotein chain B, PRO2619, PRO02044, and complex-forming glycoprotein HC were new proteins that have not been previously reported in HFF using proteomic methods. Additionally, we identified alloalbumin venezia for the first time from trichloroacetic acid (TCA)-precipitated HFF. These HFF proteins could serve as new biomarkers for important human reproductive processes.

This study was designed to verify the influence of mothers on their young adults in pro-environmental consuming consciousness and behavior. The compiled data are based on the responses of questionnaires from 278 young adults who reside in Seoul, Korea. The data were analyzed by frequency, standard deviation, mean, unitary dispersion, rank revolution analysis, analysis of variance (ANOVA), and multiple regression analysis by SPSS 14.0K for Windows. This study has discovered the following: First. A mother's pro-environmental consuming behavior is one of the most important factors significantly influencing a young adult's consciousness and behavior. Second. A friendly and positive consciousness about the environment enhances pro-environmental consuming behavior. A close inter-relationship exists between consciousness and behavior. However, some significant discrepancy was found between pro-environmental consuming consciousness and pro-environmental consuming behavior; that is, the level of pro-environmental consciousness was higher than the level of pro-environmental behavior. Third. Sensitivity to environmental information influenced pro-environmental consumption consciousness and behavior. Female students are more concerned about and sensitive to environmental matters than are male students. Fourth. Among the subordinate dependent variables, recycling behavior is most influenced by independent variables. Among the pro-environmental consuming behavior sector, a mother's disposal behavior exerts the most influence on the young adult's behavior. In the results of this study, it is pointed out that it is absolutely necessary fur young adults to bring up their practice level of pro-environmental purchase and consuming behaviors, and it is advised that appropriate and relevant education programs should be developed.

This research was conducted to get the basic information for improving production amount as well as fruit quality by using Prohaxadion-Calcium (Pro-Ca) used as 'Sato Nishiki', cherry cultivar, which is most frequently cultivated in Korea. In fruiting trees, we used Pro-ca and concentration of treatment selected 150, 200 and $250\;mg{\cdot}L^{-1}$. When treating Pro-Ca $200\;mg{\cdot}L^{-1}$, we could get the highest effect on inhibition of shoot growth. All treatments of Pro-Ca were increased chlorophyll a and b, respectively compared with control. Although treatments of Pro-Ca treatment showed the decreased effect on leaf area and there was no difference in fruit quality among treatments. Also, Pro-Ca $250\;mg{\cdot}L^{-1}$, sprayed 3 times, and pclobutrazol ($PP_{333}$) 500 and $1,000\;mg{\cdot}L^{-1}$, applicated soil, were treated to 1 year old plnted pot. Pro-Ca and $PP_{333}$ showed inhibition of shoot growth, especially, Pro-Ca showed the more effect than $pp_{333}$ on growth inhibition. Soil applications of $pp_{333}$ showed less effect to enlargement of tree trunk compared to Pro-Ca and control. Pro-Ca and $pp_{333}$ were not difference in number of inter-nodes when comparing to control, but they on decreased leaf area and increased chlorophyll.

Currently the systematic approaches to implementing CALS and reducing time-to-market are widely used, which is based on the concept of PDM. The concept of PDM is to maximize the time-to-market benefits of concurrent engineering while maintaining control of product data and distributing, it automatically to the people who need it - when they need it. In this paper, we developed PRO browser with these PDM functions which have the functions of managing the information of product, process and organization consistently and inter-referencing efficiently the data required in enaluation. In the PRO browser, throughout the design process improvement, the generic environments are embodied which make it possible to reduce product development sycle time and improve the quality of design.

To solve the problem of low inter-operability of systems and low reusability caused by not being standardized and common-shared development foundation between software developers, the government has proposed e-Government(eGov) standard framework. However, the development method based on eGov standard framework is not easy to learn and to use fluently, because it is so dissimilar the existing traditional development method. In this paper, we propose an approach for developing web applications by reusing common components of eGov standard framework, and describe about the case study of developing Can_Pro(Computer Aided Nutritional analysis program for Professionals) based on eGov standard framework. Consequently, we show improvement in productivity and reduction budget through reusability of common components and eGov standard framework.

Objectives: We calculated life expectancy and inequalities therein by income for the period of 2016-2018 across the 253 electoral constituencies of the 20th National Assembly election in Korea. Methods: We obtained population and death data between 2016 and 2018 from the National Health Information Database and constructed abridged life tables using standard life table procedures according to gender and income quintiles for the electoral constituencies of the 20th National Assembly election held in 2016. Results: Life expectancy across the 253 constituencies ranged from 80.51 years to 87.05 years, corresponding to a gap of 6.54 years. The life expectancy difference by income across the 253 constituencies ranged from 2.94 years to 10.67 years. In each province, the difference in life expectancy by income across electoral constituencies was generally greater than the inter-constituency differences. Constituencies in capital and metropolitan areas showed a higher life expectancy and a lower life expectancy difference by income than constituencies in rural areas. Conclusions: Pro-rich inequalities in life expectancy by income existed in every electoral constituency in Korea. Both intra-constituency and inter-constituency socioeconomic inequalities in health should be highlighted in future policy-making in the National Assembly.
