Objectives : To investigate the information searching behavior of health care consumers according to sociodemographic characteristics. Methods : A questionnaire survey was conducted of 1,507 persons who were selected through a multi-stage stratified area cluster sampling of the Republic of Korea, excluding the province of Jeiu-do. Personal were conducted through a door-to-door survey between 27 July and 10 August 1999. Results : 80.5% of respondents used more than one source of information and those $40\sim59$ years of age, female, a housewife or student and those who claimed a religion demonstrated more active information searching behavior. A personal informer was used significantly more in those $20\sim39$ years old, female, and those who claimed a religion. Clerical workers, those with post-secondary education and a monthly income greater than 2,000,000 won ($1500) were more actively used a public informer. Low socioeconomic status and older persons used an experimental informer when they chose a health care institution. Conclusion : Regardless of the sociodemographic characteristics, personal and experimental informers were the most useful source of information. Because appropriate information was not easy to obtain, the health care consumer was dependent upon word-of-mouth communication(personal informer) when using health care services.

The purpose of this study was to evaluate the information searching behavior of consumer by type of medical institution. A questionnaire survey was conducted of 1,507 persons who were selected through a multi-stage stratified area cluster sampling in nationwide level, excluding Jeju-Do. Personal survey was conducted through door-to door survey from 27 July to 10 August 1999. The main results of this research was as following; 1. The proportion of information searching of respondents ranged from 91.5-95.2%. Even though the proportion of user in university hospital was slightly high, there was not significant statistically by type of medical institution. In terms of information source, personal informer was most common information source in all type of medical institution. Public informers were more frequently used in university hospital visitors and professional informer in general and university hospital visitors. 2. Comparing to searching intensity, user informer and professional informer's influences were more powerful, but not statistically significant. In analysis of unit influence for information source, written informer or public informer was more powerful in clinic visitor, professional informer and written informer in university hospital visitor. 3. Information which consumer want to know mostly were about on special potential and career of physician. The clinic visitor wanted to know about institutional location and kindness of medical personnel. The university hospital visitor also wanted to know about facilities and convenience of process. Comparing to institution selection criteria of consumers at 1991, quality related criteria were recognized more importantly in outpatient and dental services. But in case of inpatient services, convenience factor was recognized more importantly. In conclusion, the effort for specific marketing plan by type of medical institution should be needed. And more concern on information searching behavior of consumer will be needed.

This paper discusses a searching method for special markers attached with persons in a surveillance video stream. The marker is a small plate with infrared LEDs, which is called a spatiotemporal marker because it shows a 2-D sequential pattern synchronized with video frames. The search is based on the motion vectors which is the same as one in video compression. The experiments using prototype markers show that the proposed method is practical. Though the method is applicable to a video stream independently, it can decrease total computation cost if motion vector analyses of a video compression and the proposed method is unified.

In Korea, about 8.3% over aged 65 are suffering from Alzheimer's disease or other type of dementia. Among dementia-related behaviors, wandering is the one of strongest factors on burden and stress of caregivers. On Lee and Kwon's report with community living persons with dementia, upto 85% of caregivers reported wandering as a problem. Wandering is a frequently encountered problem in communities and long-term care facilities, but it is among least understood dementia. related behavior. Despite the prevalence of wandering, its significant adverse outcomes, and the increase in persons with dementia in Korea, no systematic research has been conducted in Korea. The purpose of this study is to review on literature related to wandering behavior among persons with dementia. The specific topics related to wandering are included: definition, the prevalence of dementia and wandering behavior, the influencing factor on wandering, outcomes of wandering behavior, and the measurement method. Wandering is defined as "aimless walking" and "Meandering, aimless or repetitive locomotion that exposes one to harm and is incongruent with boundaries, limits, or obstacles". Wandering is viewed as a problematic behavior, however, it has to be understood as need-driven compromised behavior. For example, wandering may be an expression of searching for familiar person and/or place. Recently, in Korea, there is an effort for establishing the therapeutic environment for elders who are wanderers in long-term-care facilities. Cognitive impairment of persons with dementia is found to be a consistent factor on wandering behavior through many national and international studies. The adverse outcomes of wandering are serious problem in persons with dementia as well as their caregivers. The adverse outcomes include falls, fractures, getting lost, use of restraints, or even death. In fact, wandering is one of the major reasons for a patient to be institutionalized. For measurement of wandering behavior, two methods are broadly used: observation using stop watch, and survey form. A revised instrument of the Korean version of Algase wandering scale (K_RAWS) is established the psychometric properties (Son, Song, & Lim, 2006) demonstrating valid and reliable instrument in measuring wandering behavior among persons with dementia who are residing in communities. K_RAWS has a 39 items with six subscales including persistent walking, repetitive walking, spatial disorientation, eloping behavior, negative outcome, and mealtime impulsivity. In conclusion, studies including the prevalence of wandering behavior and predictive factors on wandering should be conducted to understand wandering clearly before developing any types of intervention.

The epoch-making event of history called "JE JU 4.3" took place in JE JU beautiful island on liberation political situation in 1948. The cruelties of this event were reported awful life loss over 30,000, cruel slaughter by government, scorched villages in mountain area, silence exaction and disadvantage of implication for long time over 40 years. But, the real features are in still a fog.. Recently, the searching movement has arised owing to democracy atmosphere and literature works with "JE JU4.3" materials were published from 1988 and the government announced official apologies in 2003. The novel "The Sun-set on Halla Mt", one of those works, is accessible to real history due to its time/space back ground and the real name of persons who were related with this event. It is important for readers to consider the difference between real history and fiction story. Because a historical novel should be evaluated by writer's theme rather than history character.

군사용으로 개발되었던 드론은 취미, 레저뿐만 아니라 방송촬영, 공공분야까지 사용분야가 급속도로 확대되고 있으며, 네팔로 봉사활동을 갔다가 눈사태로 실종된 한국인 교사 4명을 찾기 위해 수색용 드론이 투입되기도 하였다. 정부는 드론 산업을 육성하기 위하여 정책적으로 공공분야에서의 드론의 활용을 장려하고 있으며, 향후 시장도 확대될 것으로 예상된다. 본 연구에서는 공공부문에서 드론의 활용이 확대되고 있는 시점에서 공공기관의 드론 활용에 대한 개선방안과 구체적 이용방향을 제시하고자 하였으며, 이를 위하여 관련 전문가에 대한 인터뷰, 공공기관의 드론 운용규정 분석 및 경찰의 실종자 수색용 드론 운용사례를 검토하였다. 우선 드론의 도입 이전에 전문성을 갖춘 인력을 확보하고 충분한 검토를 통해 드론의 사양 등을 결정하고, 드론의 도입에 있어서도 면밀한 검사가 이루어진 후에 임무에 투입이 되어야 할 것이다. 다음으로 드론 운용에 대한 근거규정을 마련하고 이에 따른 매뉴얼을 작성할 필요가 있다. 마지막으로 드론 비행은 추락의 위험성이 있으며, 특히 공공부문에서의 드론은 목적 달성을 위하여 취미용 드론에 비하여 대형화 전문화되어 있기 때문에 드론 운영의 전담인력 확보가 필수적이다. 본 연구는 경찰청의 실종자 수색용 드론에 대해서만 구체적인 분석을 실시하였으며, 인터뷰 대상자도 적다는 한계가 있다. 후속 연구에서는 여러 공공기관을 대상으로 분석을 실시할 필요가 있으며, 인터뷰 외에도 설문조사가 각종 자료나 통계 등의 분석이 이루어져야 할 것이다.

Objectives : This study investigated the health information such as the general health information, the health product information, and the hospital information, and we wanted to identify the association between internet health information and the health related behavior by analyzing the process after people search the Internet. Methods : A telephone survey with structured questionnaire was performed by trained surveyors. The respondents were sampled proportionate to the Korean demographic distribution with considering the city size and the populations' ages and gender. The survey was conducted from October 2006 to November 2006. Results : Out of 3,758 successfully connected persons of age 20 or more, 871(23.2%) respondents had used Internet health information during the last year. The purposes of searching the Internet for health was, 1) to get general health information (717 cases, 81.0%), 2) shopping for health product (109 cases, 12.3%) and 3) seeking information about hospital selection (59 cases, 6.7%). Our research showed that the process after searching the Internet for health information depends on the purpose of the search. 68.8% of the searchers for general health information, 67% of the searchers for health product shopping and 64.4% of the searchers seeking information to guide hospital selection were satisfied with their Internet search. However one third of the respondents reported not being satisfied with the result of the search. Conclusions : Unsatisfied consumers with internet health information tended to ask lay referrals from others or they gave up seeking health information. The health information system should be improved to increase the accessibility and to provide reliable and effective information. Also, a more user-centric community is needed in order to strengthen the effective role of lay referrals among the internet users.

Purpose : The purpose of this study was to analyze Korean qualitative research studies on cerebral palsy and provide a basis for future direction of research. Methods : Twenty-six articles were selected by searching 4 Korean databases (NDSL, DBpia, KISS, and RISS) and reviewing the list of additional references. All the articles were analyzed and assessed using the Consolidated criteria for Reporting Qualitative research (COREQ). Results : Seventeen qualitative studies and 9 mixed quantitative and qualitative studies were selected, and methodologies such as case study (42.3 %), constant comparative method (23.1 %) and phenomenology (23.1 %) were used. The studies investigated the effects of interventions (38.5 %), support programs (30.8 %), and life experiences (26.9 %). Among the participants, 50.0 % were persons with disabilities only, 19.2 % were parents only, and 30.8 % were combination of persons with disabilities, parents, teachers, and therapists. The number of participants in most studies was 2-9 (57.7 %). The COREQ evaluation of the selected articles revealed many shortcomings in the studies. Interview guidelines were used only in 26.9 % of the studies. In particular, many articles did not describe in detail the characteristics of researchers and the relationship between researchers and the participants. Conclusion : In future, various research methodologies and research checklists must be used to stimulate high-quality qualitative research with on cerebral palsy.
