Generally, the objectives of the geodetic network adjustments are for solving the configuration of geodetic net-works and the problem of observation plans. In this study, assuming that the configuration is fixed, for improving the accuracy of geodetic networks, we focus on choosing adjustment control points and adjustment methods. By choosing adjustment control points and adjustment methods, the adjustment result accuracy of national geodetic networks can be different. So, in this study, we introduce the algorithm that use free network adjustment concept to minimize the displacements of new station points but fixing existing control points. Then, us-ing adjustment results, we can check the errors of existing control points. After checking the errors of existing control point, in case of severe error points in existing control points, we change those points into unknown station points and repeat the algorithm to optimize the coordinates of new station points. As applying this algorithm to simulation network, we can check the errors of existing control points. And changing severe error points into unknown station points, we can decrease the errors of network and optimize the coordinates of new station points. From the results of simulation network adjustment, we think that, as applying this algorithms to sequential adjustment of geodetic network and public surveying that using national geodetic network, the accuracy of network adjustments can be improved.

Introduction : In Korea, national attention to the workplace health promotion programs (HPP) for employees began in early 1990s. Governmental supports for the HPP and education programs have given to the employees. The purpose of this study is to find the performance degree of employees' health promoting lifestyle(HPL). Subjects and Methods : For this study, 615 employees who attended governmental educations were selected as research samples. The tool for measuring HPL used in this study was developed for Korean by In-Sook Park in 1995. It is composed of 4-point scaled 60 items and divided into 11 subcategories. The data were collected by self reporting questionnaires from June to December in 1997. Those data were analyzed percentile, mean, standard deviation, ANOVA, t-test with SAS program. Major findings are as follows; 1. The total mean score of the employees' HPL performance was 2.66. The average scores of 'harmonious relationships' category were the highest as 3.11, whereas the one of 'professional health maintenance' were the lowest as 2.02. The remains were 'sanitary life'(2.90), 'emotional support(2.85), 'regular diet'(2.84), 'self achievement'(2.78), 'healthy diet'(2.56), 'rest and sleep'(2.56), 'exercise and activity'(2.54), 'diet control'(2.53), 'self-control'(2.52). 2. The factors affecting HLP were category of industries and sex, age, marital status, education level, major, educational experience of health promotion, among personal characteristics. The employees of service industries, female, older age, married, nurse, educated for health promotion, graduated from junior college performed HLP more than the others. 3. The participation rates of employees for HPP were 12.4%, because of limited time and facilities and equipments. Recommendations; 1. The regulation for performing the health promotion programs in the industries is essential for activating industrial health promoting movement. 2. More governmental supports for educations and services for health promotion programs in the industries are needed. 3. For behavioral changes of the employees, the contents of educations have to consist of exercise and activity, rest and sleep, diet and smoking habits. 4. The evaluating studies for ready made health promotion programs in the industries are expected.

Background : Economic evaluation of clinical pharmacokinetic consultation services for theophylline, which is being widely used recently, is considered in patients for both proper care and cost efficiency. Mathods : This is a cost-benefit analysis of clinical pharmacokinetic consultation service for theophylline. Trial groups were chosen from 2 general hospitals which was performing clinical pharmacokinetic consultation- services in 1998. Control group was chosen from another one general hospital. The analysis includes 25 patients (sample patients) for trial group and 17 patients for control group. Results : On the basis of incremental analysis, it is estimated that the total (direct and indirect) annual costs of the clinical, pharmacokinetic services of theophylline for the patients in the trial group was about \65 million, whereas total annual benefits from those services was estimated to be about \551 million. The net benefits incurred to the sample patients, thus calculated, was about \485 million per year. In the analysis, we assumed that indirect benefits accruing to those services were non-existent. If that amount was included, the estimated net benefits would be much greater than the calculated one. Conclusion : We found that clinical pharmacokinetic consultation services for theophylline could produce more marginal benefits than marginal costs by those services from the social point of view. More controlled prospective trial in the future would be helpful for affirmation of the results of this study.

In existing public parcel locker, if there is not an empty storage box, it is not used. In existing private parcel locker, because it is a lock-based locker, there is strong weak point in security. To prevent these drawbacks, the proposed private parcel locker has a menu-driven remote control application which is operated on smartphone. The lock release and the security number change by the security number which is stored in the Electrically erasable read-only memory, are possible. As a result, the proposed method has better advantages than the existing methods in terms of unnecessariness of empty storage box check and security by the security number accumulation function and the automatic SMS transmission representing parcel locker operation result.

As a 'network of networks,' the Internet globally connects a huge number of regional and individual networks and provides us with new hopes and possibilities. However, a nation-state as well as the legal order of the 'state'(constitution) has limitations that are all too clear in order to regulate this new world formed by the Internet. It will soon be impossible for a single state to control these global information networks, and they will not be consistently and vertically operated and managed by anyone. As a result, ideologies or jurisdictions that support the legal order of a nation-state are no longer sufficient to control information delivery beyond borders. Furthermore, the development of the Internet and emergence of cyber space in the information society has led to the idea of 'extinction' of nation-states. Nevertheless, the conclusion that the state will be extinct due to the development of the information society is still nothing more than a hasty assumption. In other words, the information society does not indicate the end of the state. Rather, we must now clearly perceive that the object of our research and discussions must be the role and function of the nation-state in the newly emerged information society in the global aspect and international aspect, as well as in relationships with individuals or organizations that now have unimaginably strong information power. It is clear at this point that nation-states will lose the function and authority they have enjoyed or exercised to a certain degree, but this certainly does not indicate that nation-states are, and will be, unnecessary or useless. Rather, it is necessary to focus on the list of tasks that must be accepted by nation-states in the changed information society, as well as responsibilities and means to perform those tasks.

Purpose: The purpose of this study was to investigate the effects of preclinical clinical performance examination (CPX) on nursing students' confidence in their nursing skills and critical thinking competence. Methods: The design of this research was one-group pretest-posttest, and the participants were 112 nursing students. The preclinical CPX consisted of a clinical examination, patient-nurse relationship, oral test of related knowledge, written test of the nursing process, and debriefing using comprehensive scenarios based on real patient cases. The confidence of nursing skills consisted of an 8-item NRS and the critical thinking competence consisted of a 12-item 4-point scale developed by researchers and measured in both the pretest and posttest. The collected data were analyzed using paired t-tests, ANOVA, and Pearson correlation coefficients. Results: The score for confidence in nursing skills (t=10.60, p<.001) and that for critical thinking competence (t=7.03, p<.001) increased significantly after preclinical CPX. Conclusion: This study showed that preclinical CPX was effective in improving nursing students' confidence in their nursing skills and critical thinking competence. Therefore, preclinical CPX is expected to be utilized in nursing practice education. Additional studies including those on control groups are recommended to compare differences between the preclinical CPX group and control group.

As respiratory syncytial virus(RSV) is transmitted either via directly contact with an infected case or via indirectly contaminated fomites or skin, the major preventive measures are strict hand hygiene, early detection of transmitted sources, and rapid isolation of RSV patients. Especially early detection of hidden cases is the most critical control measure when an index case was notified in a postpartum center. The Guideline of Korea Centers for Diseases Control and Prevention defines potential contacts in an epidemiologic survey as admitted newborns, parents of index cases, center's workers, and visitors for 10 days before the first diagnosis day of index case. However, it needs to classify potential contacts in more detail in order to conduct a successful survey. Authors conducted to search related literatures and appraise the evidences. Firstly, potential contacts would be classified into RSV-related symptomatic contacts(SxC) and asymptomatic contacts. And then, mother, caring workers, and visitors of the index cases among asymptomatic contacts would be defined as the asymptomatic close contacts(ASCC). Finally, the rest would be defined as the asymptomatic regular contacts(ASRC). The defined test using reverse transcription-PCR is applied to SxC and ASCC, and decision of isolation or regular activities are made according to the results. The rapid antigen detection test kits are applied to ASRC. These suggestions might be helpful to detect hidden cases earlier and prevent a further infection.

BACKGROUND/OBJECTIVES: The objective of this study was to describe the development process of the Korean Healthy Eating Index (KHEI) based on the Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: The components of KHEI were selected based on Dietary Guidelines for Koreans, domestic and overseas dietary quality indices, and results of the analysis of association with chronic diseases. The standards for scoring of KHEI were selected based on the 2015 Dietary Reference Intakes for Koreans (KDRI). The KHEI scores of Korean adults were calculated using a 1-day 24-h recall data in the 2013-2015 KNHANES. RESULTS: The KHEI included eight adequacy components evaluating the proper intake of recommended foods such as fruit, vegetable, and milk and three moderation components evaluating the consumption of food that limit intake such as sodium and saturated fatty acid. In addition, three balance components assessing the balance of energy intake were included. The KHEI score was defined to range from the minimum of 0 point to the maximum of 100 points. Among Korean adults, the total KHEI score was 63.2 out of 100. Gender and age differences were found in the average of total KHEI scores. Women showed higher score than men (61.7 in men and 64.7 in women, respectively). By age group, 20s and 30s showed the lowest scores with 57.4 and 61.1 respectively, and the scores increased with age by peaking at 67.8 in ages 60-69 and slowed down again in ages 70 or over. CONCLUSIONS: The KHEI can be useful for establishing and assessing national nutritional policies and in epidemiological studies to assess the relationship between overall dietary quality and chronic diseases. KHEI will need to be continuously updated to reflect changes in dietary guidelines and the KDRI.

Museum buildings display artefacts for public education and enjoyment, ensuring their long-term safety and the comfort of visitors by following strict indoor environment control protocols using mechanical Heating, Ventilation and Air Conditioning (HVAC) systems to keep the (environmental) variables at a fixed comfort level. Maintaining this requires constant supply of energy currently mostly sourced from the combustion of fossil fuels which exacerbates climate change. However, a review on the effects of the indoor environmental variables on museum artefacts as well as museum visitors revealed that there is no specific point at which artefact deterioration occurs, and that there are wide ranges of conditions that guarantee the long-term safety of artefacts and human comfort. Visits to museum buildings in hot-humid tropical climate of Nigeria revealed that strict indoor environmental practices were adopted. Even when appropriate micro-climatic conditions are provided for artefacts, mechanical HVAC systems remain necessary for visitor comfort because almost no consideration is given to natural ventilation. With the current global push towards energy management, this paper reviewed passive environmental control practices, architectural design strategies, and discusses the adaptation of double skin façade with jali screens, and the notion of smart materials, which can satisfy the range of requirements for the long-term safety of artefacts and levels of human comfort in buildings in hot-humid tropical climate, without mechanical HVAC systems. This review would inspire more discussions on passive, energy efficient, smart and climate responsible popular architecture, challenging current thinking on the impact of the more accepted representative architecture.
