Permanent rental housing, the construction of which was strongly financed by the central government, is regarded as a social housing for those who fall within the lowest income bracket. Differing from "public rental housing", offered to tenants for sale after a five year rental period, this type of housing is intended for rental use on a long-tenn basis. At present, about 190,000 permanent rental housing units exist in Korea. According to a statistics, 15.6% of its residents did not pay their management fee and rental payment in 4 or more months in 2005, which places stress on the housing management. Based on the "eviction condition" stipulated in the tenancy agreement for permanent rental housing, a householder owning assets or a vehicle which is not used as his means of living, who is overdue with his management fee and rental payment for a long time, may be evicted from the house. However, there are many conflicts and problems between administrators/housing managers and residents in the process of enforcing this regulation. The purpose of this study is to explore the key issues associated with the present situation and the reasons why so many management fee and rental payment for permanent rental housing are overdue. For the purpose of research, data were collected from 10,990 permanent rental housing residents nationwide via a questionnaire survey in February 2007. One third of the respondents had an experience of more than 2 months overdue since they have moved in current residence. For further analysis, the respondents were divided into three groups, based on their working ability. The major finding showed that the group of respondents who have working ability required a more practical plan, such as employment, to have a sustainable life, while the other group of no labor force indicated a need for more housing allowance from the government. To suggest more specific alternatives for the subject of housing payment overdue, further comparison study should be performed between the residents of permanent rental housing and other low income tenants in private housing sector.

Purpose: The purpose of the study is to evaluate the effectiveness of anterior segmental osteotomy (ASO) in bimaxillary protrusion (BP) patients by comparison between the mandibular soft and hard tissue changes from orthodontic treatment and ASO. Methods: All 44 patients were diagnosed with BP in Kyung-Hee Medical Center. Orthodontic treatment with teeth extractions were underwent by 23 patients (Group A) and 21 patients underwent ASO (Group B). Mandibular soft and hard tissue changes were measured and evaluated, which were based on the vertical and horizontal reference line in lateral cephalometric radiographs. Statistical significance between the changes and correlation between each measurement were analyzed. Results: The amount of B point movement was lesser than that of the lower incisal tip (LIT) retraction, and LIT was tilted lingually in group A. The posterior movement discrepancy between LIT and B point was insignificant, and the inclination of lower incisor was not changed in group B. The soft tissues, including the lower lip, showed a posterior movement and reduction in the depth of mento-labial groove. According to the correlation analysis, the movement of the lower incisor was significantly related to the movement of the lower lip in group A, and the movement of the lower incisor was significantly related to that of the movement of lower lip, B point and Pog in group B. Conclusion: The orthodontic treatment in BP patients results in posterior tilting movement of the lower incisor, but ASO results in the bodily movement of the lower incisor. Consequently, ASO is more effective in BP cases because it ensures the controlled movement of the lower incisors.

딥러닝 기술은 실세계의 객체를 분류하거나 인식하기 위해서 사용된다. 이를 위해서 준비된 많은 데이터를 고성능 컴퓨터에서 학습한 후에, 그 학습모델을 인식기에 탑재하여 각종 객체들을 인식한다. 이러한 인식기는 다양한 환경에서 사용되면서 인식하지 못하는 객체들이나 인식률이 낮은 객체들이 발생할 수 있다. 이런 문제를 해결하기 위해서 실세계 객체들을 주기적으로 학습하여 인식률을 높인다. 하지만, 즉각적인 인식률 향상이 어려울 뿐만 아니라, 임베디드 디바이스 등에 탑재되어 있는 인식기에서 학습하는 것이 쉽지 않다. 따라서, 본 논문에서는 임베디드 디바이스에 적용 가능한 부분 학습 기반의 실시간 손글씨 인식기를 제안한다. 제안된 인식기는 사용자 요청 시마다 임베디드 디바이스에서 부분 학습을 할 수 있는 환경을 제공하고, 실시간으로 인식기의 학습모델이 갱신된다. 이로 인해서 인식기의 지능이 지속적으로 향상됨으로 최초에 인식하지 못했던 손글씨에 대해 인식이 가능해진다. 이렇게 제안된 인식기는 RK3399 임베디드 디바이스에서 22개의 숫자와 글자에 대해서 학습과 추론이 가능하다는 것을 실험을 통하여 사람 손으로 쓴 은행 계좌명과 계좌번호를 인식할 수 있는 개인화된 지능을 가진 스마트 기기에 활용 가능할 것으로 기대된다. Deep learning is widely utilized to classify or recognize objects of real-world. An abundance of data is trained on high-performance computers and a trained model is generated, and then the model is loaded in an inferencer. The inferencer is used in various environments, so that it may cause unrecognized objects or low-accuracy objects. To solve this problem, real-world objects are collected and they are trained periodically. However, not only is it difficult to immediately improve the recognition rate, but is not easy to learn an inferencer on embedded devices. We propose a real-time handwriting recognizer based on partial learning on embedded devices. The recognizer provides a training environment which partially learn on embedded devices at every user request, and its trained model is updated in real time. As this can improve intelligence of the recognizer automatically, recognition rate of unrecognized handwriting increases. We experimentally prove that learning and reasoning are possible for 22 numbers and letters on RK3399 devices.

Investigation of meridian line and acupoints as anatomical entities should be very important, as acupuncture and meridian massage for medical purpose in the hospital or for skin care in beauty shop are each based on the traditional meridian theory. We isolated tubular structures under the skin of rabbits where the traditional meridian lines are located. The characteristics of these tubular structures isolated from the abdominal wall matches those of Bonghan tubes and Bonghan tubules found by Bong Han Kim. The Bonghan theory established by Bong Han Kim suggests that meridian lines consist of Bonghan tubes and Bonghan tubules. We could observe the presence of large cells inside the Bonghan tubule and the presence of small granules referred to as Sanal in Bonghan theory inside the striae consisting of the Bonghan tubules. Present research suggests that there exist a third unique tubular structure where Sanals flow other than Bonghan tube and Bonghan tubules.

The purpose of this study was to identify perception on housing welfare of social welfare practitioners. Specific research interest was focused on the area of housing welfare services and necessity, problems when execute housing welfare services, and activating strategy of housing welfare. For the research purpose, questionnaires were distributed to 537 people who work in the field of social welfare including social welfare officials in local government authorities and social workers at community welfare centers nationwide by mail and e-mail and 405 questionnaires were analyzed using SPSS 15.0 program. Respondents thought that the supply of public rental housing was the most important service to promote housing welfare. They also indicated the most serious problem was the lack of budget and housing welfare services and programs. As main reasons of local government's passive attitude toward housing welfare services and programs, respondents mentioned low interest level of housing welfare and lack of housing welfare education. Most of the respondents agreed the necessity of introducing the curricula related to housing welfare and expected to spread interest toward housing welfare in the field of social welfare.

병행 Java 프로그램의 확장적 경합탐지를 위한 JDI 기반의 투명한 감시도구

김영주,구인본,배병진,전용기,Kim, Young-Joo,Kuh, In-Bon,Bae, Byoung-Jin,Jun, Yong-Kee 한국정보처리학회 2009 정보처리학회논문지 A Vol.16 No.2

병행 Java 프로그램의 경합은 프로그램의 비결정성을 초래하므로 반드시 탐지되어야 한다. 이러한 경합을 수행 중에 탐지하기 위해서는 스레드에 대한 수행양상과 모든 접근사건들을 감시할 수 있어야 한다. 기존의 경합탐지 기법들은 프로그램의 수행중에 기록된 파일들을 분석하거나 대상 프로그램을 수정하여 감시하므로 스레드나 모든 접근사건들에 대한 감시가 현실적으로 어렵다. 본 연구에서는 JDI(Java Debug Interface)를 이용하여 스레드에 대한 수행양상과 모든 접근사건을 감시하여 확장적 경합탐지를 할 수 있는 투명한 감시도구를 제안한다. 여기서 JDI는 JDPA(Java Platform Debugger Architecture)에서 제공하는 상위 레벨의 100% 순수 자바 인터페이스로써 자바프로그램의 수행중에 특정 정보를 제공할 수 있다. 그리고 제안된 도구의 투명성을 입증하기 위해서 벤치마크 프로그램으로 실험한 결과, 모든 스레드와 접근사건들을 프로그램 수정없이 감시할 수 있었고 프로그램의 감시시간이 20배 이상 증가되었다. Race conditions in current Java programs must be detected because it may cause unexpected result by non-deterministic executions. For detecting such races during program execution, execution flows of all threads and all access events can be monitored. It is difficult for previous race detection techniques to monitor all threads and access events in actuality because these techniques analyze the files traced during program execution or modify original source programs and then monitor these programs. This paper presents a transparent scalable monitoring tool to detect races using JDI(Java Debug Interface) where JDI is 100% pure java interface to provide in JDPA(Java Platform Debugger Architecture) and is able to provide information corresponding to events occurred in run-time of programs. This tool thus can monitor execution flows of all threads and all access events without program modification. We prove transparency of the presented tool and grasp the efficiency of it using a set of published benchmark programs. As a result of this, the suggested tool can monitor all threads and accesses of these programs without their modification, and their monitoring time is increased to more than 20 times.

In recent, the concept of management is emphasizing the aspects of social welfare, especially in permanent rental housing that most of the residents are very low income households. Although the quality of service for the residents of permanent rental housing was improved comparatively, it still needs to continually change in response to the needs of residents. To figure out the better way of supporting the service for the residents of permanent rental housing, this study examined the role and function of management office and compared perception on management services between management staffs and residents of permanent rental housing. Based on the in-depth interview with 5 managers of permanent rental housing, two types of survey questionnaire (residents/staffs of management office) were developed for the research purpose. A sample of 89 management office staffs and 111 residents were used for the data analysis. Most of the respondents recognized the need of a cooperation system among management office, social welfare center, and residents for providing better management system and welfare service.

To provide the basic information for the water quality management of the Sumjin River Basin, delivery ratios for flow duration were studied. Using the day-interval data set of discharge and water quality observed from the Chooryeong-cheon watershed, the flow-duration and discharge-load relation curves for the watershed were established, then the load-duration curve was constructed. Delivery ratios for flow duration were also developed. Delivery ratios showed wide variation according to flow conditions. In general, delivery ratio of high flow condition showed higher value reflecting nonpoint source pollution contribution from the forest dominating watershed. To resolve this problem, a regression model explaining the relation between flow rate and delivery ratio was suggested. The delivery ratios for different flow regime could be used for pollutant load estimation and TMDL (Total maximum daily load) development.
