Wireless smart sensors enable new approaches to improve structural health monitoring (SHM) practices through the use of distributed data processing. Such an approach is scalable to the large number of sensor nodes required for high-fidelity modal analysis and damage detection. While much of the technology associated with smart sensors has been available for nearly a decade, there have been limited numbers of fulls-cale implementations due to the lack of critical hardware and software elements. This research develops a flexible wireless smart sensor framework for full-scale, autonomous SHM that integrates the necessary software and hardware while addressing key implementation requirements. The Imote2 smart sensor platform is employed, providing the computation and communication resources that support demanding sensor network applications such as SHM of civil infrastructure. A multi-metric Imote2 sensor board with onboard signal processing specifically designed for SHM applications has been designed and validated. The framework software is based on a service-oriented architecture that is modular, reusable and extensible, thus allowing engineers to more readily realize the potential of smart sensor technology. Flexible network management software combines a sleep/wake cycle for enhanced power efficiency with threshold detection for triggering network wide operations such as synchronized sensing or decentralized modal analysis. The framework developed in this research has been validated on a full-scale a cable-stayed bridge in South Korea.
Purpose: The purpose of this study was to investigate the levels of physical symptoms, anxiety, depression, and quality of life (QOL) during chemotherapy for colorectal cancer patients in South Korea and to identify factors influencing their QOL. Methods: Data were collected from 144 colorectal cancer patients receiving chemotherapy during 2012 at one general hospital located in Seoul. Physical symptoms were measured by the M. D. Anderson Symptom Inventory-Gastrointestinal Cancer Module, and anxiety and depression were measured by the Hospital Anxiety Depression Scale. QOL was measured by the Functional Assessment of Cancer Therapy-Colorectal. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, $Scheff{\acute{e}}$ post hoc test, Pearson correlation and stepwise multiple regression. Results: Mean age of the participants was 56.6 and most of them were not employed. In terms of cancer stage, 38.2% were in stage 3, followed by stage 4 (34.7%). The most frequent symptom was lack of appetite, followed by sleep disturbance and fatigue. The mean score for anxiety was 5.40 with a prevalence of 23% and that of depression 8.85 with a prevalence of 64.6%. The mean score for quality of life was 81.93 out of 136 and 75.3% of the variance in QOL was explained by depression, symptoms, anxiety, treatment place, and occupational status. Depression was the strongest predictive factor. Conclusion: Oncology professionals need to pay special attention to relieving depression as well as physical symptoms to improve QOL during chemotherapy for colorectal cancer patients.

The different growth steps of human show the different energetic phenomenon such as the strength of triple energizer, the sale of extra meridian, and the stability of 12 meridians. So we have to understand the physiological and pathological phenomena on this point of view. Especially atopic dermatitis means the loss of adaptability under the lack of genuine energy. If you approach to this disease not with any perception of excess or deficiency of the human genuine energy but with simple symptom enumeration or partial diagnosis, it will be dangerous. So we must approach to this disease with more concrete and objective body-centered standard. Thus when we cure and diagnose infants with this disease, we should focus on stablizing the "Energy of Earth(土)" digestive ability, under the consideration of inducement to the enough "Byun-Jeung-Hu(變蒸候)" and the function of Triple Energizer. Through this process we can lead infants to the beginning equipment state(始全). Until 7 years old, we should stabilize the Link Vessel(維脈) by clarifying interior and exterior classification of Nutritive Element and Defensive Energy to control the child's energy of metal(金), water(水), wood(木) and fire(火) in the basis of the energy of earth(土). And also we should stabilize the Heel Vessel(?脈) through the Water and Fire complement each other to control the movements and to control sleep and awakening. Through this process, we can lead children to the basal equipment state(本全). After then, until adolescent phase, we should control 12 meridian and 8 extra meridian by leading vital function to be harmonized and prosperous on the basis of the meridian to reach the mature equipment state(旣全). Adult atopic dermatitis should be controlled through conciliation between meridian and internal organs by differentiating male from female.

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.
This study explored differences in how medical and surgical patients compare on the degree of hospital stress and their subjective physical status. Subjects were 343 medical and surgical patients in five university hospitals in Seoul and Taegu. They responded to the Hospital Stress Rating Scale and a self-report on physical status. The controlled variables were age, education, number of previous hospitalizations and seriousness of the illness. Medical and surgical patient differences on nine factors of the hospital stres scale and nine areas of physical conditions were reported as follows edplored : 1. 1) There was not a statistically significant difference at the .05 level in the total mean score for hospital stress between medical patients and surgical patients. 2) The mean score of the factor lack of information (M=2.308) for medical patients was higher than the mean score (M=2.064) of the surgical patients. 3) The mean scores of the factor of discomfort (M=2.130), loss of independence (M=1.889) for surgical patients were higher than for medical patients. 2. 1) There was a statistically significant difference at the .05 level in the total mean score for physical status between medical patients and surgical patients. 2) The mean scores were lower in subjective physical status for surgical patients(S) than for medical patients (M) ; stomach condition (S : M=2.8433, M : M=3.0-000), self-assistance(S : M=3.0373, M : M=3.4498), movement (S : M=2.6716, M : M=3.2392), interest in your surroundings (S : M=3.0522, M : M=3.2632). 3. Patients scoring high on the subjective physical status such as sleep, appetite, stomach condition bowel condition and urination states had higher scores in hospital stress than with patients scoring low on those subjective Physical status. The results suggest that subjective physical status might be on expression of hospital stress. Also patients with high scores in subjective physical statas might be predicted have a high level of stress on admission. And surgical patients had a higher level of hospital stress than medical patients.
Objective : Korean employees tend to release their stress by alcohol drinking. This study aimed to investigate the association between job stress and problematic drinking in Korean employees. Methods : The study participants were 72,119 employees who attended health screenings and responded to the Alcohol Use Disorder Identification Test-Korea (AUDIT-K), Korean Occupational Stress Scale-Short Form (KOSS-SF), Center for Epidemiologic Study-Depression (CES-D), Beck Anxiety Inventory (BAI) and questionnaire on suicidal ideation and sociodemographic characteristics. We investigated the sociodemographic and clinical characteristics of the problematic drinking group ($AUIDT-K{\geq}12$) and used binary logistic regression to determine the impact of job stress on problematic drinking. Results : Age, gender, marital status, education year, sleep duration, obesity, smoking, suicidal ideation, and depression and anxiety showed significant differences between the problematic drinking group and normal group. Among the various kinds of job stresses, job insecurity and lack of reward were associated with problematic drinking. Conclusion : The result of this study suggested that certain kinds of job stress might be associated with problematic drinking in Korean employees.
Purpose: This study aimed to identify occupational stress and health problems as well as turnover reasons among leavers in novice nurses and to estimate factors which might affect turnover by comparing them to stayers. Methods: In this study, secondary analysis of data gathered from the Shift Work Nurse's Health and Turnover studies, was carried out. The data were collected from 204 stayers who have been working for 18 months since 2018 and 48 leavers who left within the same period at two tertiary hospitals in Seoul. The reasons for turnover, occupational stress, and 8 types of health problems were recorded. The data were analyzed using SAS 9.4 to obtain descriptive statistics. In parallel, Pearson's chi-squared test, Fisher's exact test, and independent t-test were also conducted. Results: The main reasons for turnover were job stress and difficult interpersonal relationships in the workplace. Occupational stress of leavers was higher than stayers, especially in the subscales of interpersonal conflict, organizational system, lack of reward, and occupational climate. Among the 8 types of health problems, the depression prevalence of leavers was higher compared to stayers and showed marginal significance. Unexpectedly, the sleep disturbance prevalence of stayers was significantly higher compared to leavers. Conclusion: To reduce the turnover rate of novice nurses, education on how to cope with occupational stress is needed. A customized program for novice nurses to overcome the difficulties of interpersonal relations would be helpful.
In recent years, interests in health promotion have been stimulated by the epidemiological transition from infectious to chronic diseases as lead ing causes of death, the aging of the population, rapidly escalating health care costs, and epidemiologic findings linking individual risk to morbidity and mortality. It is not surprising that the workplace has been targeted as a promising setting for health promotion. In Korea, national attention to the opportunities for workplace health promotion began in the first 1990s. But there is no in depth study to identify the relating factors to the health promotion program in the workplace. The objective of this study is behavioral and physical characteristics to find that in crease the person's risk for a range of health problems and to analysis other characteristics to influence the degree of his/her intention to change health behavior. In addition, this study is purposed to present the process of planning health promotion program in the workplace. To accomplish these objectives, one workplaces was selected. And 363 employees in those workplaces were served as subjects for the study. Major findings in this study are as follows. (1) They have many risk factors such as smoking, drinking, lack of sleep, law rate of regular exercise, irregular eating, stress. (2) Some of the health risk factors such as smoking, drinking, and stress have the negative correlation to the intention to change. (3) Among cognitive and socio-environmental factors, significant predictors to the intention are attitude and social support. (4) In the cluster analysis to segment the target population in to homogeneous unit, three clusters of lifestyle are specified. (5) Smoking cessation and exercise program are planned for the risk group to change their behavior.
The pediatrics has other diagnosis and treatment compared with an adult. It is therefore, the children have different pathogenesis, pathology from adult's. The special feature of the children is two. Firstly, children are the body of the pure Yang[純陽之體], which means the growth and development of them are very fast. Secondly, they have weak muscle, skeletal and digestive function. So we must consider health-preserving method in different physiology and pathology aspects of the children. The children have weak digestive functions, so they should be careful to avoid eating greasy food and overeating. They must eat the nourishing Eum[滋陰] food. The children should wear thin clothes as possible. If the children wear clothes so thick, it promote the Yang (陽), so the Eum(陰) is hurted. The children are to be lack of Eum[陰不足], so they need to grow and raise the Eum(陰) in this way which the lower body is cool. Sleep is important ways to generate Eum Essence[陰精]. So the children should take a bed as change of the season. Children's muscles and skeleton are growing so incomplete that they are hard to handle Wind-Cold pathogen[風寒邪]. Therefore, the children should be training vital Essence and Gi(氣) with appropriate exercise. We should be careful treatment the Hwayeoljeung(火熱證) with purgation[瀉下] - bitter in taste and cold in nature[苦寒藥], aromatic herb[芳香性藥物], sudorific herb[發汗藥] In addition, child has weak digestive function, so doctor should not use a lot of nourishment[滋補].

An efficient management system for parking lots and traffic monitoring in a metropolitan city is a very important issue, which is tightly closed to qualify of life. While a residential permit parking program has been contributing to resolve the lack of parking places, there has been no autonomous authentication system due to no apparent entrance gate and smallness of each parking zone. In this paper, we propose and implement an authentication system for residential permit parking lot using wireless sensor networks, which is cost-effective and even no need for additional managing person. Through the experimental evaluation, we analyzed relationship between the life time of sensor nodes and the various values of sleep periods to minimize power consumption of the nodes, and also showed that the difference of luminance sensed by each sensor node is at least 45 or bigger between when the parking place is occupied or not, resultingly it can be used to decide whether a parking place is occupied or not by simply detecting the change of luminance sensed.
