This research has been implemented based on the area of #369 Dowon-dong, Dalseo-gu, Dae-gu which is considered as a place with satisfactory characteristics for the flow of fresh air into the city. Simulations of the target area both prior to the development plan and after apartment complex blocking were analyzed in regard to blocking planning and pilotis based on the main direction of wind, $90^{\circ}$ (east wind) and $180^{\circ}$ (south wind). In addition, congested wind corridor flow in the target place was identified through a pollution spread simulation according to the wind corridor. Therefore, the flow of wind in the one area is affected by the blocking of the complex and the main direction of the wind. Also blocking, in regard of pilotis, provides a better flow of wind. This study was implemented based on wind formation by apartment complex planning, so further study on the other factors affecting the flow of a wind corridor along with block planning and pilotis need to be carried out. Sustainable environmental factors through analysis of the environmental factors have to be analyzed. Moreover, building and complementing fundamental resources and systematic devices should be supported.

In this paper, an evolution of software reliability engineering in a large-scale software project is summarized. The considered software consists of many components, called functional blocks in software of switching system. These functional blocks are served as the unit of coding and test, and the software is continuously updated by adding new functional blocks. We are mainly concerned with the analysis of the effects of these software components in software reliability and reliability evolution. We analyze the static characteristics of the software related to software reliability using collected failure data during system test. We also discussed a pattern which represents a local and global growth of the software reliability as version evolves. To find the pattern of system software, we apply the S-shaped model to a collection of failure data sets of each evolutionary version and the Goel-Okumoto(G-O) model to a grouped overall failure data set. We expect this pattern analysis will be helpful to plan and manage necessary human/resources fur a new similar software project which is developed under the same developing circumstances by estimating the total software failures with respect to its size and time.

This article is researched to analyze what kinds of projects were conducted by the special grant, the balanced development special account(BSDA), and the municipal projects in the case of Sangjucity and Seochengun, in the introduction time of the bock grants of BSDA and the municipal development plan in 2010. Furthermore this study presents the problems and the direction of improvement. For the territorial integration of a regional development in long-term, I suggest that the spacial grant and BSDA are necessary to be integrated because of ambiguous difference. And also the block grants of current 24 projects in 7 groups should be reclassified as the concept and the functional feature of pluralistic rural development.

This study was designed to understand the residential experience of Korean women living in tropical country. For qualitative research, interviewees were selected by snowball sampling among Korean women living in Malaysia for over 20 years. The selection criteria for interviewees included husband's nationality, occupational experience, future living plan, frequency of travel to Korea. In-depth group and individual interviews were conducted from August 23 to October 7 2014. Subsequently (1) interviewees' general residential experiences in Malaysia were summarized, (2) interviewee's identity and lifestyle with housing pathways approach were clarified, (3) interviewees' residential experiences in 5 issues, reciprocity in residential area, intention of environmental change, meaning of housing and interaction, housing adaptation, and residential satisfaction/dissatisfaction were prescribed and interpreted. In conclusion, the reflection of interviewees' experiences in tropical country, suggested variations of housing structure type within a residential complex, air well and pocket by setback in building block for improving ventilation and noise prevention from neighbors, and ceiling fans in the house were suggested for the upcoming subtropical climate in Korea. Full option and minus options were also suggested for the presale market to reduce before occupancy remodeling needs. The research results implies valuable suggestions for a multicultural society, ecological housing and stronger communities.

We have processed the GPS data using several high quality GPS data processing softwares for last decade. Bernes and GIPSY II are some of them. Though these programs have different characteristics in terms of structures and processing philosophies, high quality results from these are still comparable. KASI Space Geodesy Research Division has developed several GNSS data processing softwares like the quasi real-time ionospheric parameter estimator, orbit propagator and estimator, and precision positioning estimator. However, we are currently in needs of our own comprehensive GNSS data processing software with the European Galileo system on the horizon. KASI team has worked on a preliminary pilot project for the software and is making block pieces for the software. The roadmap, the description, and brief results of KASIOPEA (KASI Orbit Propagator and EstimAtor) are presented in this paper.

The main function of a container terminal is to load container freights into vessels and discharge them from vessels. The container terminal needs to utilize its resources effectively in order to improve the productivity of it. This study deals with the deployment model for yard cranes whose type is RMGC (rail mounted gantry crane). We develop a mathematical model for the deployment of yard cranes. The model considers not only the deployment but also the storage plans. It could be divided into two cases according to whether inter-block movements of yard cranes are allowed or not, during the same period Numerical examples are solved and analyzed to validate the model. Then, additional experiments are performed to compare the performance of the model with that of a previous model without the re-deployment of yard cranes.

Existing real estate markets are monopolized because they are capital intensive and have information asymmetry. However, with the advent of the Fourth Industrial Revolution, technology is converging in various industries based on information technology (IT), and the real estate market is also developing a new field called "PropTech". According to this trend, new PropTech technologies are emerging in various real estate services sectors in Korea, but the electronic contract system, which accounts for the largest portion of the real estate industry, is still cited as a complex identification process and long processing time. Therefore, in this paper, we propose an improvement plan for the current electronic contract system through the introduction of blockchain technology, which is drawing attention with the development of PropTech, and explore the possibility of introduction by producing an experimental model of blockchain-applied electronic contract system in a programming language.

In radiation treatment, it is unavoidable to block the influence of scattered ray on a skin and prevent internal normal organs from being exposed to radiation. It is fair to say that radiation therapy aims to reduce an absorbed dose of normal tissues. In particular, in radiation therapy of left-sided breast cancer, the internal neighboring organs are normal breast tissues, the heart, and the lung. The side effects on the heart include cardioplegy and myocardial infarction. This study tried to observe changes in the volume and dose of the heart in general radiation therapy plan and respiratory control based radiation therapy plan for patients with left-sided breast cancer, and to find the heart's volume and dose generated by respiration. According to the 4D computer tomography (CT), a volume of the heart had $12.8{\pm}8.7cc$ on average, and its dose had $17.3{\pm}12.1cGy$ on average. The differences in the volume and dose may cause side effects in radiation treatment. Therefore, it is necessary to apply respiratory control technique to establish the radiation treatment plan based on an accurate position of the heart.

The present study was conducted with aim for establishing the framework of integrated veteran policy for unified Korea through the analysis of the North Korea's veteran policy. For the purpose, this study reviewed the legal system and implementation process concerning the North Korea's veteran policy and analyzed the establishment of fundamental framework of unification and the implications from the North Korea's veteran policy for unified Korea. The review of the North Korea's veteran policy covered the beginning of the North Korea's veteran policy to the present. Based on the findings of the review, this study revealed the necessity of re-establishing the principle of veteran policy in preparation for unification and proposed a plan for unified veteran policy. The results from this study are expected to be a meaningful milestone to unified veteran policy after unification. It is reasonably expected that there will remain considerable differences and conflicting factors, which could block the path to national integration, between two countries and their peoples after unification. Therefore, it is more important to make a thorough preparation and form social consensus than any other. In this respect, national policy for veterans should go back to basics and be reviewed to be ready for unification. Although different in time, the North Korea's veteran policy was and is the base of the nation's system and source engine for development every period. Re-designing the principle of veteran policy should reflect both symbols of the unified nation and the national identity, but also of socially integrated spirit. Therefore, it must include the spirit of patriotism and awareness of national security. Furthermore, as for the integration of veteran policies for unification, it is especially important for two countries to possess and share common historical consciousness. The unified veteran policy should be integrated on this base.
