Since the 1980's the school of Busan metropolitan city has been converted into the other land-use such as high-rise apartment houses, commercial and office buildings. School facilities are available to locate in green area due to not restricted by land use zone. And the location of school facilities were closely related with the school district, distribution of neighborhood unit, safety of students, and so on. The purpose of this study is to understand the location characteristic of school - moved sites in Busan metropolitan city.

Social media marketing has gained attention from marketers because of the growing number of social media users. Considering the unique context of each company or organization behind the marketing is necessary when choosing and applying various social media marketing strategies to ensure achievement of better business performance. However, previous studies have focused on context-specific marketing strategies. Accordingly, this study aims to develop context-specific social media marketing strategies. In this study, we first develop a conceptual framework with two items, namely, brand awareness and business orientation of an organization, as criteria, and classify the framework into four contexts. We then propose context-specific social media marketing strategies for each of the contexts. We examine the framework and proposed social media marketing strategies based on multiple case studies. The primary contribution of this study is our context-specific social media marketing strategies.

The importance of information media in personal lives has increased rapidly, indicating the average ages of users are becoming younger. School-age children, despite the inconsequential differences, are reported to have used the internet for their free time, information search, communications, and education. Recent researches are focused on various variables affecting internet-addictions since these problems have become a major issue in education due to prolonged use of the internet or mobile. The regulations as a preventative measure and the setting of standard are also considered as major issues of research. In terms of policy, there should be revisions on laws and regulations about the internet and mobile in order to protect school-age children from vicious environments. For the education's part, there should be appropriate amount of education, for children and their parents, on how to use computers and the internet properly and how to prevent internet-addiction.

The information related to legislation is massive, and it takes much time and effort to manually build the legislation ontology. Thus, studies on machine-based automated building methods are underway. However, the studies to automatically construct such systems focus on using TBox construction, and those based on automated ABox construction, which corresponds to instances, theoretical systems and data building cases, has not yet been sufficiently developed. Therefore, this paper suggests using a semi-automatic ABox construction method based on sentence patterns to automatically build the ontology for the legislation of the Republic of Korea. Precision and Recall experiments were conducted to further discuss the performance of the suggested method. These experiments provide a comparison between the manual classification, and the triples built by the machines of the legal information by assessing the corresponding numerical values.

Objectives This review investigates the effectiveness of electroacupuncture for impairment of motor and sensory functions after spinal cord injury. Methods The databases used for the search were PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), National Digital Science Library (NDSL), Koreanstudies Information Service System (KISS), Research Information Sharing Service (RISS), KMBASE, and Oriental Medicine Advanced Searching Integrated System (OASIS). The literature were searched using a total of 9 domestic and foreign databases. Randomized controlled trials (RCTs) using electroacupuncture as an intervention was selected. The selected studies are analyzed the risk of bias through Cochrane risk-of-bias tool, and meta-analysis was perfomed using RevMan version 5.3 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). Results A total of 14 RCT studies were selected through 9 domestic and foreign databases, and analyzed. As a result of meta-analysis, when electroacupuncture was performed together with rehabilitation treatment or western drug treatment, it was effective in the recovery of motor and sensory functions of spinal cord injury patients. Conclusions This review suggests that electroacupuncture can be applied as an effective treatment for the recovery of motor and sensory functions of spinal cord injuries. However, there are several limitations, including the small number and heterogeneity of the included studies, as well as their poor methodological quality. Therefore, further, higher-quality studies should be required.

This review examined recently published (July 2014 to June 2017), randomized controlled trials (RCTs) which investigated the safety and effectiveness of combined Korean medicine/complementary alternative medicine (CAM) and Western medicine, to indicate the direction for integrative medical practice. The Korean Medicine Convergence Research Information Center evidence-based medicine database (KMCRIC EBM DB) was used to retrieve relevant RCTs indexed in the last 3 years. Study design, country, sample size, disease/condition with the Korean Standard Classification of Diseases code, interventions, direction of outcomes, and adverse events were extracted and summarized. A total of 93 RCTs were included in this review. Acupuncture/moxibustion was the most commonly used intervention (n = 47; 51%), and 19% (n = 18) of the studies treated musculoskeletal disorders, followed by circulatory disorders (n = 16; 17%), and mental and behavioral disorders (n = 9; 10%). Integrative treatment was reported as more effective than monotherapy in approximately 83% of these studies. Adverse events were poorly reported in most studies. This review suggests that integrative treatments are feasible, effective, and safe for various diseases/conditions, based on the evidence from recently published RCTs. Future studies on integrative healthcare are warranted.

3축 가속도 센서의 활용이 점차 다양화 되면서 3차원 공간에서의 동작 인식에 대한 개발이 늘어나는 추세이다. 본 논문에서는 모바일기기의 동작을 바탕으로 한 3차원 공간에서의 동작 인식 방법을 제안한다. 동작의 인식은 3축 가속도 센서를 이용하며, 3차원 공간을 14가지 방향으로 나누어서 인식 한다. 기존의 연구에서는 3차원 가속도 데이터를 처리하여 동작을 인식하는 여러 가지 방법만을 제안했을 뿐, 3차원 공간을 방향으로 나누어 접근한 시도는 아직까지 없었다. 본 연구의 이러한 시도는 앞으로 모바일기기에서 사용자 인터페이스를 보다 쉽게 이용할 수 있는 방향으로 활용 가능할 것으로 보인다.

With the rapid increase of a population, various problems arise from poor education environment and devalued quality of education. Internet cyber School, a new learning system may be one of the best methods to remedy the situation. We conducted a related questionnaire on the high school in PUSAN city for the study of the cyber learning system. Many high school student agreed that Internet cyber education hour should be matched up with the school hour. They must make a use of the cyber school Service to help the students study by themselves. And we also decide that the implemented service will increase the psychological effect spreading to other teaming fields.

계획기법 이란 목적을 달성하기 위해 일련의 행동 순서를 찾는 것이다. 계획 기법을 통해 수립된 많은 행동들을 로봇 등 에이전트가 실행할 때 예기치 않은 문제들이 발생하게 된다. 이러한 문제들을 실시간으로 해결하여 에이전트가 주어진 목적을 달성할 수 있도록 하여야 한다. 그러한 문제점을 해결하는 방법에는 반응 계획기법, 재 계획기법, 그리고 지역 복구기법 등이 있다. 본 논문에서는 재 계획기법과 지역 복구기법의 장점을 가지는 이정표상태 계획기법을 간단히 제안하고 이정표 상태의 생성 방법을 연구하였다. 이정표 상태들은 수립된 계획의 모의 실행을 통하여 생성하였으며 행동 실행에 관련된 조건들의 criticality value를 이용하는 방법과 계획에 나타나는 행동들의 빈도수를 이용하는 방법을 제안 하였다.
