This study was conducted to search the health food intake behavioral intentions of male workers. The health-related behavior of 150 subjects were compared(smoke, alcohol drink, breakfast, BMI, sleep, exercise and health check). On the basis of the Theory of Planned Behavior, the factors health-food intake behavior were evaluated; there were normative beliefs, motivation for compliance, subjective norms, social influence factors, and barriers as perceived behavior control. The results were showed with five points by the Likert scale and Significance by t-test. The most frequently consumed health food was tea(3.40/4points) followed by healthy drinks(2.49/4). As behavioral beliefs, if consumption of 'nutritional supplements'(3.61/5) and 'fatigue recovery'(3.62/5) received the highest scores. As a result, the idea of 'nutritional supplements'(3.94/5) and 'fatigue recovery'(4.06/5) were the important aspects, but others were also positively evaluated. As a sub-factor of subjective norms on normative beliefs, The highest social groups to encourage consumption of health food were parents (3.93/5), and the lowest were doctors (3.02/5). The most influential people were doctors (3.67/5) and spouses (3.65/5). Barriers to consumption health food were side effects (1.09/5) and price (2.08/5). Taking Ginseng products and other processed foods (juice, honey, bamboo, etc.) were correlated with health concern (p<0.05). Taking traditional stamina foods was correlated with dietary habit recognition (p<0.05). Mineral intake was positively correlated with age. Healthy drinks was negative (p<0.05). Minerals and supplement consumption were correlated with the practice of healthy behavior (p<0.01).

Objectives: Despite the recent emphasis on a patient-centered chronic care model, few studies have investigated its use in older adults in South Korea. We explored how older Korean adults perceive and cope with their chronic illness. Methods: We conducted focus group interviews in Seoul, Korea in January 2010. Focus groups were formed by disease type (hypertension and type 2 diabetes) and gender using purposive sampling. Inclusion criteria were patients aged 60 and over who had been diagnosed with diabetes or hypertension and received care at a community health center for at least six months prior to participation. Interview data were analyzed through descriptive content analysis. Results: Among personal factors, most participants felt overwhelmed when they received their diagnosis. However, with time and control of their acute symptoms using medication, their worry diminished and participants tended to denying being identified as a patient or sick person. Among socio-familial factors, participants reported experiencing stigma with their chronic illness and feeling it was a symbol of weakness. Instead of modifying their lifestyles, which might interfere with their social relationships, they resorted to only following their medicine regime prescribed by their doctor. Participants also reported feeling that their doctor only prescribed medications and acted in an authoritative and threatening manner to induce and reinforce participants' compliance with treatment. Conclusions: For successful patient-centered management of chronic illnesses, supportive environments that include family, friends, and healthcare providers should be established.

Although excessive intake of sodium is known to cause various diseases and threaten public health and policies for reducing overconsumption of sodium are being implemented, the theoretical research on sodium intake is incomplete. This study attempted to provide a policy basis by examining whether or not planned behavior theory, which is a typical health communication theory used to describe health-related behaviors, can be applied to explain sodium intake behavior. Especially, sodium ingestion behaviors were compared using the theory of actions planned for men and women as well as young people, middle-aged, and elderly persons, who are predicted to show differences in eating habits. In this study, questionnaires were prepared to measure the daily eating habits of subjects and subordinate factors of planned behavior theory: behavioral beliefs, outcome expectations, normative beliefs, compliance motivation, and control beliefs. Questionnaires were given to 93 college students and their families. As a result of the difference analysis and path analysis of the questionnaire responses, the following suggestions were obtained. First, age difference is more obvious than sex difference in terms of low salt intentions. For example, older people are healthier than younger people in terms of eating habits and health concerns. Second, the elderly are more likely to practice the low-salt formula when they are provided information on the benefits and effects of the low-salt formula compared to younger ones. Third, systematic efforts are needed to promote a culture that emphasizes the health benefits of a low salt diet rather than providing piecemeal information on the advantages and effects of a low salt diet.

Background: The present study was conducted to determine knowledge level of technicians working in hospitals about testicular cancer (TC) and self-examination of testicles (TSE) and to determine levels of consciousness and implementation status about TSE. Materials and Methods: This cross-sectional study was conducted with technicians working in hospitals (n=243) between $2^{nd}$ January-$31^{st}$ May 2012 at private and governmental hospitals in urban Kayseri. Healthy control subjects (n=235) who were similar to technicians in terms of age, education level and income status were also included to the study. Chi-square test was used in comparison of categorical variables. Results: Technicians were significantly more aware of TC than controls, but the latter were found to have significantly more information about TSE. There was no significant difference between the two groups in terms of knowing how to do TSE and 80% of both groups were unaware this exam. Of technicians, 19.8% and of controls, 25.5% did TSE, the difference being statistically insignificant. First reason for not doing TSE was "not-knowing" among technicians (48.1%) while it was "ignorance" among controls (66.8%). Of technicians doing TSE, 37.5% did as it came to their mind while 51.7% of controls performed TSE several times in the previous year. Technicians were significantly more afraid of getting TC than controls (p=0.037). Conclusions: It was determined in the present study that rates of TSE were similar between technicians and controls. However compliance with the recommended frequency and right method was low. Consequently, public health education should be planned and applied in order to increase the knowledge of TC and TSE.

Changes in gastrointestinal tissue blood volume induced by variations of venous pressure between 6 and 40 mmHg were studied in 32 rabbits. Venous pressure lowering was produced by withdrawal of appropriate volume of blood and venous pressure elevation was obtained by partial occlusion of intra-thoracic vena cava inferior. Estimation of regional tissue blood volume was performed by means of regional distribution of injected $Cr^{51}-labeled$ red blood cells. The following results were obtained. 1. At the normal control venous pressure value of 18 mmHg, spleen showed the highest value of tissue blood volume expressed on weight basis, namely, $111{\mu}l/gm$, Liver tissue blood volume was $95\;{\mu}l/gm$, small intestine 24 and stomach $21\;{\mu}l/gm$, respectively. 2. Linear relationships were observed between venous pressure change and gastrointestinal tissue blood volume. The coefficients of correlation were: in spleen r=0.723; in liver r=0.791; in stomach r=0.704, respectively. In small intestine the relationship was less clear and r=0.358. Tissue blood volume of extrabdominal tissue, such as M. gastrocnemius was not influenced by venous pressure change. 3. The highest change in tissue blood volume expressed on weight basis was observed in spleen. The liver tissue showed the next highest change. Change in total tissue blood volume, however, was greatest in liver and next greatest in small intestine. This was interpreted by the fact that total weight of these two organs was much greater than that of spleen. 4. The mechanism that the change in tissue blood volume lies in the venous system which has a great compliance was discussed.

The proportion of digital evidence in criminal cases has increased, while at the same time, the spread of the Internet has made it easy to delete information that is stored in another place and thus, the Internet is being used to delete online criminal evidence. To respond quickly and effectively to cybercrime, 29 countries signed the Convention on Cybercrime in 2001 through the Council of Europe. Article 16 of the Convention relates to the expedited preservation of stored computer data and requires signatories to adopt legislative measures to enable its competent authorities to order expeditious preservation of specified computer data where there are grounds to believe that the data is particularly vulnerable to loss or modification. More than 60 countries have joined the Convention since 2001 and have made efforts to improve their legal system in line with it. The United States legislated 18 U.S.C. § 2703(f) to preserve electronic evidence pending the issuance of a court order. The German Code of Criminal Procedure §§ 94~95 allows prosecution authorities to seize evidence or issue production orders without court control in urgent circumstances. A custodian shall be obliged to surrender evidence upon a request that evidence be preserved, and non-compliance results in punishment. Japan legislated the Criminal Procedure Act § 197(3) and (4) to establish a legal base for requesting that electronic records that are stored by an ISP not be deleted. The Korean Criminal Procedure Act § 184 outlines procedures for the preservation of evidence but does not adequately address the expeditious preservation of digital evidence that may be vulnerable to deletion. This paper analyzes nine considerations, including request subjects, requirements, and cost reimbursement to establish directions to improve the legal system for the expedited preservation of digital evidence. A new method to preserve online digital evidence in urgent cases is necessary.

최근 4년 간 발생한 해양사고 통계자료(중앙해양안전심판원, 2018)에 의하면 충돌사고의 대부분이 어선을 포함한 소형선에서 발생하고 있으며 경계소홀, 항행법규 미준수 등의 인적 요인이 충돌사고의 주요 원인이 되고 있다. 이에 따라 사고 예방을 위해 교육, 훈련을 확대 강화하고 있지만 소형선에 대한 사고는 여전히 일어나고 있는 실정이며 인적 요인으로 유발되는 사고를 줄이고자 기술적 방안이 지속적으로 개발되고 있다. 본 연구에서도 상대적으로 고속인 소형선에 송·수신 주기가 빠른 WAVE 통신기술을 적용하여 충돌 회피시스템 구성하므로 인적 요인으로 인해 발생하는 사고를 감소시키고자 하였다. 그에 따라 통신 범위의 적정성 판단하고 회피동작 시간과 범위를 설정하였으며 그 것을 토대로 제어 알고리즘 고안 하였다. 그리고 통신단말기-제어기-조타장치를 구성하고 충돌회피 모의 시뮬레이션을 수행하므로 경보신호 발생 시 회피동작의 정상 구현을 확인하였다.

This paper presents the temperature-pressure characteristics of a new SMH actuator using a Peltier module. The SMH actuator is characterized by its small size, low weight, noiseless operation, and compliance similar to that of the human body. The simple SMH actuator, consisting of the plated hydrogen-absorbing alloys as a power source, Peltier elements as a heat source, and a cylinder with metal bellows as a functioning part has been developed. To improve the thermal conductivity of the hydrogen-absorbing alloy, an assembly of copper pipes has been used. It is well known that hydrogen-absorbing alloys can reversibly absorb and desorb a large amount of hydrogen, more than about 1000 times of their own volume. The hydrogen equilibrium pressure increases when hydrogen is desorbed by heating of the hydrogen-absorbing alloys, whereas by cooling the alloys, the hydrogen equilibrium pressure decreases and hydrogen is absorbed. The new special metal hydride (SMH) actuator uses the reversible reaction between the heat energy and mechanical energy of a hydrogen absorbing alloys. The desirable characteristics of SMH actuator, which makes it suitable for the uses in medical and rehabilitation applications, have been also studied. For this purpose, the characteristics of the new SMH actuator for different temperature, pressure, and external load were explored.

Background: Difficult-to-treat asthma afflicts a small percentage of the asthma population. However, these patients remain refractory to treat, and account for 40% to 50% of the health costs of asthma treatment, incurring significant morbidity. We conducted a multi-center cross-sectional study to characterize difficult-to-treat asthma in Korea. Methods: Subjects with difficult-to-treat asthma and subjects with controlled asthma were recruited from 5 outpatient clinics of referral hospitals. We reviewed medical records of previous 6 months and obtained patient-reported questionnaires composed of treatment compliance, asthma control, and instruments for stress, anxiety, and depression. Results: We recruited 21 subjects with difficult-to-treat asthma and 110 subjects with controlled asthma into the study. The subjects with difficult-to-treat asthma were associated with longer treatment periods, more increased health care utilization, more medication (oral corticosteroids, number of medication), and more anxiety disorder compared to those of well-controlled asthmatics. There was no difference in age, gender, history of allergy, serum IgE, blood eosinophil count, or body mass index between the 2 groups. Conclusion: Difficult-to-treat asthma is characterized by increased health care utilization and more co-morbidity of anxiety.
