BACKGROUND/OBJECTIVES: A large number of studies on anemia have focused mostly on pregnant women or children. The vegetarian population, which is another potential risk group for anemia, remains largely unexplored. Therefore, this cross-sectional study examined the associations of the sociodemographic, lifestyle, nutritional, and psychological factors with the anemia status among female adult vegetarians. SUBJECTS/METHODS: A total of 177 female vegetarians were recruited from a Buddhist and Hindu organization in Selangor, Malaysia. The participants completed a self-administered questionnaire, which analyzed their sociodemographic characteristics, physical activity level, sleep quality, depression, anxiety, and stress. The body weight, height, waist circumference, and body fat percentage of the participants were also measured. A 3-day dietary recall was conducted to assess their dietary intake. Blood samples (3 ml) were withdrawn by a nurse from each participant to determine the hemoglobin (Hb) level. RESULTS: The findings revealed 28.2% of the participants to be anemic. The age group (AOR = 2.46, 95% CI = 1.19-5.05), marital status (AOR = 2.69, 95% CI = 1.27-5.71), and percentage of energy from protein (AOR = 5.52, 95% CI = 1.41-21.65) were the significant predictors of anemia. CONCLUSIONS: Anemia is a public health problem among female vegetarians in this study. Health promotion programs that target female adult vegetarians should be conducted to manage and prevent anemia, particularly among those who are married, aged 50 and below, and with an inadequate protein intake.

온라인 게임 시장이 성장하면서 게임 봇의 사용은 게임 서비스에 가장 심각한 문제를 야기하고 있다. 본 논문에 서는 MMORPG 장르의 게임 봇 중 채집을 진행하는 봇을 탐지하기 위한 채집 좌표 분석 모델을 제안한다. 제안한 모델은 좌표 데이터를 기반으로 플레이어의 채집 행위를 분석 한다. 정상적인 플레이어보다 손쉽게 게임 내 재화와 아이템을 수급할 수 있는 게임 봇은 수면 시간, 캐릭터 조작 피로도와 같은 현실적인 제약의 영향을 받지 않기 때문에 채집 행위를 시도하는 좌표 구역에 차이가 발생한다. 좌표 구역을 나누고 각 플레이어의 좌표 구역 차이를 이용하여 게임 봇 플레이어와 정상적인 플레이어를 구분해 낼 수 있도록 했다. NCSoft 사의 AION 로그로 데이터셋을 만들고 random forest 모델에 적용하여 게임 봇을 탐지한 결과 재현율 72%, 정밀도 92%의 성능을 보였다.

Objectives: Parkinson's disease (PD) is currently the most rapidly increasing degenerative brain disease due to population aging and westernization of lifestyle. Levodopa is the most commonly used drug to manage PD symptoms. However, levodopa has a problem in that the wearing-off phenomenon occurs as the duration and dose of administration increase. In order to investigate the wearing-off phenomenon in PD patients and devise countermeasures, we conducted a questionnaire survey in Korea. Methods: For the study, a questionnaire with a total of seven items was prepared. Part IV of the MDS-UPDRS (Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale) and the WOQ-9 (9-symptom Wearing-off Questionnaire) were used as references. Results: Of the 48 patients who completed the questionnaire, all 47 patients who completed the questionnaire experienced the wearing-off phenomenon. Only one of the patients diagnosed with PD a year ago did not experience the wearing-off phenomenon. Patients frequently mentioned a lack of sleep and stress as aggravating factors for wearing-off. They also stated that in order to resolve the off-state, they walked, massaged, warmed up the body, stretched and exercised. Conclusions: Because wearing-off is such a common occurrence, it is thought necessary to develop wearing-off prevention and resolution measures that PD patients can use in their daily lives.

국내 건설산업의 기술자격제도는 노동부주관 $\ulcorner$국가기술자격법$\lrcorner$ 에 의하여 운영되며, 대표적인 국가자격은 건축사, 기술사 및 기사 등을 들 수 있다. 1990년 중반에 도입된 건설사업관리(CM)는 건설산업을 활성화하기 위한 필수불가결의 조건이 되고 있으나 국가자격으로 공인되지 못하고 있으며, 현안문제로서 가장 시급하다고 판단되는 전문인력 양성은 민간 CM교육기관들의 "공인민간자격"으로서 각각의 교육프로그램과 별도의 인증자격을 가지고 이루어지고 있는 실정이다. 문제는 국제공인자격으로서 신뢰성을 확보하고 있는 유일한 미국CM협회(CMAA)의 "CCM"인증자격과 미국VE협회(SAVE)의 "CVS"인증자격의 사례로 볼 때, 외국에 비하여 CM인증자격이 과다하며, 신뢰성과 효율성을 확보하지 못한 상태로 인증자격자득에게 혼란을 주면서 양산되고 있다는 점이다. 본 고에서는 국내CM인증자격의 문제점을 살펴보고 인증자격의 통합 및 체계화를 통하여 국가공인자격으로 발전하기 위한 개선방안을 제시하고자 한다.

The respiratory medical device is a medical device that delivers optimal oxygen or a certain amount of humidification to a patient by delivering artificial respiration to a patient through a machine when the patient has lost the ability to breathe spontaneously. These include respirators for use in chronic obstructive pulmonary disease and anesthesia or emergency situations, and positive airway pressure devices for treating sleep apnea, and as the population of COPD (chronic obstructive pulmonary disease) and elderly people worldwide surge, the market for the respiratory medical devices it is getting bigger. As the demand for both airway pressure devices, there is a problem that the ventilator standard is applied because the reference standard has not been established. Therefore, the boundaries between the items are blurred due to the purpose, intended use, and method of use overlapping similar items in a respiratory medical device. In addition, for both airway pressure devices, there is a problem that the ventilator standard is applied because the reference standard has not been established. Therefore, in this study, we propose clear classification criteria for the respiratory medical devices according to the purpose, intended use, and method of use and provide safety and performance evaluation guidelines for those items to help quality control of the medical devices. And to contribute to the rapid regulating and improvement of public health. This study investigated the safety and performance test methods through the principles of the respiratory medical device, national and international standards, domestic and international licensing status, and related literature surveys. The results of this study are derived from the safety and performance test items in the individual ventilator(ISO 80601-2-72), the International Standard for positive airway pressure device (ISO 80601-2-70), The safety and performance of humidifiers (ISO 80601-2-74) and the safety evaluation items related to home healthcare environment (IEC 60601-1-11), In addition, after reviewing the guidelines drawn up through expert consultation bodies including manufacturers and importers, certified test inspection institutions, academia, etc., the final guidelines were established through revision and supplementation. Therefore, in this study, we propose guidelines for evaluating the safety and performance of the respiratory medical device in accordance with growing technology development.

Grief that is not acknowledged and worked through may manifest itself in some emotional, mental or physical problem. In recent years much has been learned about coping with grief which the hospice program can utilize to help family members cope with their grief. This study was carried out to determine the helpfulness of the bereavement care of Severance Hospice and to learm more about the grief response of the bereaved. The tools used to collect data were an assessment form used in the bereavement program and the Grief Experience Inventory developed by Sanders and revised and translated 'by the researcher. Data was obtained from bereaved family members(54 for the final grief assessment and 39 for the grief response assessment) receiving bereavement follow-up, from July 1989 to March 1991. Results of the study were as follows: 1. Final Grief Assessment Regarding the resolution of their grief the majority of the bereaved accepted the reality of the death of their family member, while slightly more than three-quarters were able to express their feelings toward their loss. A large majority had returned to activities of daily living well or fairly well and had reinvested their energy in a person other than the deceased. In addition, the physical condition of the majority was good or fairly good. A majority of the bereaved considered the bereavement care to be helpful and almost three-quarters were not considered to be in need of more follow-up. 2. Grief Response Assessment Age was found to have a modoerately positive correlation to appetite disturbance(r=.41, P<.Ol) and loss of vigor(r=.37, P<.Ol) A moderately positive correlation was found between the number of contacts and sleep disturbance(r=2.38, P<.01) Significant differences were found between men and women in regard to guilt(t=2.38, P<.05), social isolation(t=2.44, P<.05) and depersonalization(t=2.07, P<.05) with men having the more intense grief. Significant differences were found in the grief responses of somatization(F=5.82, P<.001), physical symptoms(F=5.87, P<.OOl), appetite disturbance(F=4.40, P<.Ol), despair(3.79, P<,Ol), anger(Fp2.83, P<.05), social isolation(F=3.61, P<.05), guilt(F=3.62, P<.05) and depersonalization (F = 2.58, P <.05). In the first six of these grief responses mothers scored highest, followed by husbands and then wives, In the grief response of guilt, daughters scored highest and on the grief response of depersonalization sons scored highest. Only one grief response, that of sleep disturbance(t= -2.19, P<.05) was found to be statistically significant, with those family members who died at home having the higher scores. Based on the results of this study several suggestions are presented as follows: 1. Since unresolived grief can have a detrimental effect on the bereaved person's mental and phys. ical health it would be good for the nurse, to include questions related to death of family members and the bereaved person's response to the grief, in her nursing assessment. And in the case of unresolved grief the nurse should encourage the person to talk with a trusted friend or counselor and express their fellings of grief. 2. A study to determine the degree of resolution of the grief of those in the bereavement program could be carried out by use of the Grief Experience Inventory early in their bereavement and again 13 months after the death of their family member. 3. A comparison of the grief response of the bereaved in the bereavement program and bereaved not in the program could be carried out using the Grief Experience Inventory. 4. After bereavement programs have been started in other hospice programs it would be good to carry out a joint study of bereavement outcomes of those in the bereavement programs.

Despite acknowledgment that pain is likely to be a major problem for many older adults, it is difficult to estimate the frequency of pain problems for this population. The main purpose of this study was to identify the various characteristics of chronic pain in the elderly by gender. It examines by gender, pain frequency, pain intensity, number of chronic pain sites, localization of pain, impact on activities, methods of pain management, and effects of chronic pain management. The subjects were 189 elderly people(65 years and older) living in an urban area. They were surveyed at their homes. They were surveyed by interview using a closed-ended questionnaire. The survey was done from Nov. 6th. to Dec. 6th. 1997. Descriptive statistics were used to determine all of the reported pain variables. Chi-square tests were used to determine crude differences between pain intensity and gender. T-test was used to determine differences in number of pain sites between men and women. The findings are as follows ; Of the 189 subjects, 83.6% reported experiencing pain, and men reported a lower prevalence (69.5%) than women(89.2%). Women had significantly more severe pain than did men(p=.001). Lower back pain(20.2%) and leg pain(20.2%) were the most prevalent, followed by knee pain(17.4%), arm pain(13.3%), neck and shoulder pain(11.6%), and headache(9.9%). Women experienced more multiple localizations of pain(p=.0001), the greatest impact was on movement (83.5%) , followed by usual activities(60.8%), sleep(49.4%), visiting(29.1%), and hobbies and recreations(50.0%). No differences were observed between men and women in the proportion of subjects reporting a negative impact on each of these activities. The methods of pain management were hospital visit(70.9%), drug store medication(46.7%), oriental medicine clinic(32.9%), endurance(13.3%), self-management(6.3%). Drug therapy was the most effective pain management strategy(94%), followed by physical therapy(63%) and accupuncture.byssocausis(55%). The conclusion : Pain is a symptom of great clinical importance that is often associated with disability, loss of independence, and reduced quality of life. In this study chronic pain symptoms were common but unevenly distributed in men and women. The results further advance understanding of the experience and impact of pain by gender. Future studies should incorporate questions that gather systemic and more detailed information on the characteristics of pain, especially by gender and by age.

이동행태를 분석하기 위해 시.공간이론 중 3가지 제약조건인 능력제약, 조합제약, 권위제약이 공간특성에 따라 성별, 연령이 이동에 어느 정도 영향을 주는지를 분석하고 적 정 이동군집수를 결정하고자 한다. 이중 권위제약은 사회적 제약조건으로서 도시시설물이나 교통수단의 이용에 있어 사회적 신분이나 규약에 의해 이동영역이 통제되는 것을 의미한다. 공간특성에 의한 이동의 통제는, 도시와 농촌으로 구분하였을 때 도시지역 사람들은 농촌지 역 사람들에 비해 첨두시간대의 이동 참여율이 높으며, 이동군집수 결정에 있어서도 여러 연령층이 유사한 이동행태를 지니고 있음을 알 수 있다. 도시지역 사람들은 공간특성상에 따른 이동의 다양성이 군집수 결정에 상관되었으며, 이는 공간특성에 따라 이동행태가 달라 질 수 있다고 볼 수 있다. 성별 및 연령에 의한 통제 역시 사회적 제약조건으로서 이동행태 에 영향이 있음을 알 수 있다.
