The purpose of this study was a descriptive research that identified the levels of health-promoting behaviors, previous related behavior, perceived benefits/barriers, self-efficacy, and social support. In addition, it was to establish the relations among the variables, and determine the factors affecting the health-promoting behaviors. Study participants were 311 middle aged between 55-64 in urban areas, and the data were collected through self-reported structured questionnair. According to the results, the mean score for the levels of health-promoting behaviors of the late middle aged was 2.64. Also, among the variables related to health-promoting behaviors, perceived benefits were the highest score (30.7), and perceived barriers were the lowest one (2.08). Meaningful positive correlations were found among health-promoting behaviors and previous related behavior, social support, perceived benefits, and self-efficacy, but perceived barriers showed weakly negative correlations. In addition, the factors affecting health promoting behaviors were revealed in order as following: Previous health related behavior(${\beta}$=.35, p<.001), perceived benefits(${\beta}$=.32, p<.001), social support(${\beta}$=.28, p<.001), and life satisfaction(${\beta}$=.13, p<.001), and this model's explanatory power was 68.8%(F=166.71, p<.001). Based on the findings from the study, in order for the late middle aged to have a well-being old age, an health promoting education program including exercises and stress management should be provided to maintain and improve proper health promoting behaviors. The network with the same age groups also should be supported to share useful information and back up one another.

As the integrated and large-scale information is extended due to an advanced information system, a possibility of leaking out privacy increases as the time passes by. As a result, the necessity of using a privacy impact assessment (PIA) is emphasized because it can analyze and minimize the element of invasion of privacy. However, an essential audit for personal information protection is not fulfilled because most of the information system audit supervises over physical, managerial, and technical security items of system architecture area so that general items are the only things being checked. Consequently, this paper proposes that in order to minimize the invasion of personal information, the privacy impact assessment should be done. It also presents a procedure and method of personal information protection audit according to the result of the assessment. After applying the suggested method to two projects, it was confirmed that the improvements for protecting personal information were drawn from this paper.

RFID(Radio Frequency Identification) 기술의 발전은 편의성과 경제성으로 전 세계에 확산되어 사용되고 있다. 비록 세계적인 보안 표준안이 정해 지지 않았지만 RFID 보안 분야는 각 나라에 맞게 표준을 선정하여 적용되고 있다. 한편, RFID 기술의 발전으로 RFID의 칩이 소형화되고, 장거리 통신이 가능해짐에 따라 RFID 시스템에 내장된 정보를 다른 누군가가 활용하여 개인 또는 기업 등의 프라이버시를 불법으로 수집하는 피해가 발생할 수 있다. 본 논문은 RFID 시스템에서 정보의 누출을 막기 위해 해쉬 알고리즘과 초경량 스트림 암호알고리즘을 사용하여 전방위 안전성이 향상된 RFID시스템을 제안, 분석하였다.

국내 택배시장 규모는 매출 3조원 이상, 물량 13 억 상자 이상을 처리하고 있다. 2000년 6천억원에서 불과 10년 사이에 500% 이상 확대되었다. 그에 반해 소비자들의 불만 역시 증가하였다. 따라서 현재의 수작업 VOC 분류 방식으로는 적정한 대응에 한계가 있을 수 밖에 없다. 이 논문에서는 효율적인 택배불만 처리를 위해서 불만의 종류와 정도를 기계학습을 이용하여 자동분류 하는 과정 및 결과를 기술한다. 약 93,000건의 VOC(voice of customer)를 대상으로 학습 데이터를 구축하고 여러 자질 선택 기법을 비교하였으며, 기존의 다양한 문서 자동 분류 방법들을 적용해 보았다. 실험결과 지지벡터기계가 가장 좋은 성능을 보였고, 각각의 F-measure 값은 불만의 정도는 83.1%, 불만의 종류는 75.9% 로 측정되었다.

뉴스 분류 체계는 각각의 기사에 정치, 경제, 사회 등 가장 적합한 주제별로 분류하는 것으로 언론사별 분류 체계는 통일성이 없이 전혀 다르게 구성되어 사용하고 있다. 이로 인해 방대한 콘텐트를 통합하는데 많은 어려움이 있으며, 그만큼 시스템과 인력에 대해 중복 투자가 되고 있다. 이런 문제점을 개선하기 위해 국제 표준인 NewsML에 기반한 뉴스 분류에 대해 제안한다. NewsML은 XML 기반의 유연성과 확장성이 있는 구조적인 표준 형식으로 다양한 데이터 표현이 가능하여 자동 문서 범주화에 필요한 중요한 자질 선택이 가능하다. 본 논문에서는 NewsML 형식으로 되어 있는 뉴스와 그렇지 않은 뉴스를 구분하여 자동 분류에 대한 비교 실험을 한다. NewsML의 구조화된 정보를 활용한 실험이 뉴스의 제목과 본문만으로 실험한 결과보다 좋은 성능을 보여 주었으며, 그 중에서 자질 공간이 아주 큰 경우에 유용하고 문서 분류에 효과가 뛰어난 지지 벡터 기계 모델이 가장 좋은 성능을 보였다.

The purpose of this study is to conduct body shape management on women for a certain period of time to determine the structural relationship between the latent variables of life habits, social support, and life satisfaction and the impact on the quality of life. Body shape management was performed with chiropractic adjustments and myofascial relaxation therapy, and a physical therapist with 25 years of experience was used as an expert. The subject of the study was a sample of women in their 20s to 60s residing in Gwangju Metropolitan City, and women who participated in body shape management procedures more than 20 times for the study were asked to fill out a questionnaire using a self-evaluation writing method. The final analysis target was 100 people who made it reasonable to analyze the data. As a result of the study, it was found that the quality of life of women related to health can vary depending on the presence and degree of body shape management. In addition, the degree of life satisfaction varies according to the level of lifestyle and social support, and the direct, indirect, and total effects of the latent variables related to the quality of life were all significant. In this study, the usual body shape management that can improve the quality of life of women gives meaning to the opportunity for women to have desirable lifestyle and to give them a recognition that values quality of life.

We study how the three antecedents of trust such as integrity, ability and benevolence affect trust building, based on the articles extracted from the New York Times during 1981-2010. Major findings are that the ratio of negative impact on trust from integrity is 86%, whereas the ratios of positive impact on trust from ability and benevolence are 70% and 71% respectively. Statistical tests show that the hypothesis that the negative impact of integrity on trust build-up will be higher is supported, but the most unstructured benevolence related hypotheses are not confirmed due to small sample sizes. Based on the study, we suggest that the future direction of IT application should accommodate benevolence factor seriously to fulfill corporate social responsibility.

Two experiments were conducted to investigate effects of word-frequency on semantic processing of Hangul. Stimuli were two syllable words, and exemplars and target words were different in the final consonant of the second syllable in the Exp 1 and in the final consonant of the first syllable in the Exp2. Exp 1 shows the results that subjects made more errors on low frequency target words and took longer times on high frequency exemplars than on controls. In Exp 2 subjects took longer times on high frequency examplar-low frequency target word conditions than on controls. These results support the predictions of dual process models and suggest that the use of phonological and visual information depends on word frequency. Phonological activation appears to be an optional rather than obligatory process.

Disaster psychiatry is a new emerging area of psychiatry, in which psychiatrists help to minimize psychological impact of a disaster and to reduce secondary morbidities. In our society, more children and adolescents are facing disasters nowadays. Thus, the necessity for the disaster psychiatry is increasing. After a trauma, children express various symptoms in relevance to their age, development, and their environmental support. The recovery from the disaster and its long-term effect are also influenced by those factors. Psychiatric intervention in a disaster consists mainly of crises intervention and supportive psychotherapy, which includes counseling the victims, educating and providing information to the public, providing support and consultation to the community, and referring of at-risk or severely impaired individuals for more intensive clinical evaluation and care. In addition to a summarized concept of disaster psychiatry, this article presents the adverse psychological effects of children and adolescents exposed to disaster and issues related to the psychiatric intervention.
