The number of visitors to historic sites and museums in Korea has been on a rapid decrease and in order to search for creative ways to work on the problem, the study proposed a theme park-typed museum with cultural heritage applied and reviewed spatial strategies for such theme park-typed museums. Applied methods of research of this study are as follows. First, in order to understand definitions and current situations of cultural heritage use and theme park-typed museums, the study went thoroughly over all sorts of literature and reports as well as findings of advance researches on how to make a use of cultural heritage. Based on the results of the investigations, the study determined characteristics of the theme park-typed museums with cultural heritage applied which the study was proposing and the characteristics were categorized by type. Considering those characteristics and types gained in the study, the study looked for cultural heritage-based theme parks and museums in the world which were good enough to be used as research subjects in the study from the aspects of profitability and level of awareness. The study examined those theme parks and museums in the world and in the end, it found out ways to adopt the findings to the situations in Korea and discussed expecting effects as well. As to the characteristics of the theme park-typed museums with cultural heritage applied, the study divided those characteristics into mutual cooperation, location, communicability, authenticity, maintainability, education, durability, narrativity, undailiness, interactivity and leisure. The types were categorized into ride, environment direction, cartoon character and souvenir by attraction pattern. When cultural heritage is used actively, it would improve competitiveness of historic cultural sites and museums in return, making people realize the iterative structure of excavation, conservation, maintenance and use of cultural heritage. That would create many kinds of added values, re-discovering culture of the country. At the same time, it would also create a new value of culture as well. Now, it is important for us to do harder with researches on how to evolve museums and exhibition spaces. Considering that, the study is believed to make a contribution to revival of historic sites and museums in Korea but also establishment of scientific strategies.

In 1990 Home Care Education Programs started when legislation established certification for Home Care Nurses. The Ministry of Health and Welfare proposed a home care education curriculum which has 352 class hours and 248 hours of 'family nursing and practice'. Though Home Care Education Programs have been offered in 11 home care educational institutes, there has been no formal revision for the home care education programs. Also a first and second home care demonstration projects have been carried out, but there has been no research on outcomes for home care education as applied in home care practice. The purposes of this study were to identify the important content areas for home care nursing as perceived by home care nurses, and to identify their clinical competence in each of these areas, and from these to identify the education needs. The sample was 107 home care nurses who were working in home care demonstration hospitals and community-based institutions which have been offering home care services. Responses were received from 88 nurses, comprising a 82.2% return rate, and 86 were included in the final analysis. The instrument used was a modification of the instrument developed by Caie-Lawrence et(1995) and Moon's(1991) instrument on home care knowledge. The instrument's Cronbach's coefficient was 0.982. Among the respondents, 64% were working at home care demonstration hospitals and 36% were working at community-based institutions. Their home care experiences were from one month to six years, with a mean of 20.6 months. The importance rating for home care education content was 3.42 0.325, which means importance was rated relatively high. Technical aspects of home care were identified the most important. Five items 'education skill', 'counseling skill', 'interview skill', 'wound care skill', 'bed sore care skill' received 100% importance ratings. The competency rating was 2.87 0.367 and 'technical aspects of home care' was the highest, and 'application to home care skill' was the lowest. Home care nurses' education needs were identified and compared to the importance ratings and competency ratings. Eleven items were identified as the highest in the importance areas and eleven items were in the lowest competency areas. High importance ratings matched with low competency ratings determined training needs, but there was no matching items in this study. In the lowest competency areas four items were excluded, because of not being applicable in current home care practice. Therefore total eighteen items were identified as home care education needs. These items are 'bed sore care skill', 'malpractice', 'wound care skill', 'general infection control', 'change and management of tracheostomy tubes', 'CVA patient care', 'Hospice care', 'pain management', 'urinary catheterization and management', 'L-tube insertion and managements', 'Respirator use and management skill', 'infant care', 'prevention to burnout', 'child assessment', 'CAPD', 'infant assessment', 'computer literacy', and 'psychiatry patient care'.

The bilateral sagittal split ramus osteotomy (BSSRO) is preferred method of surgical correction for mandibular prognathism, retrognathism and asymmetry. This technique performed from primarily an intraoral incision to avoid a scar. After forward movement of the distal segment of the mandible, healing of bone by primary or secondary intention is easily accomplished through large areas of cancellous bony overlap. When rigid fixation is used for the BSSRO, it is possible to open the mouth during the immediate post-operative period because it promotes the healing process. Although this surgical procedure has been well-documented, the incidence of postoperative trigeminal neurosensory disorder in the region of the inferior alveolar nerve and the mental nerve remains one of the major complication. However, evaluation of objective methods for sensory recovery patterns is insufficient although most patients find their sensory return. Neurometer electrodiagnostic device performs automated neuroselective sensory nerve conduction threshold evaluation by determining current perception threshold (CPT) measures. The purpose of this study was to evaluate the sensory recovery patterns of inferior alveolar and mental nerve over time. Nerve examination with a neurometer was performed in 30 patients undergoing the BSSRO at pre-operative, post-operative 1-, 2-, 4- week, and 2-, 3-, 4-, 5-, 6- month follow-up visits after the osteotomy to compare the differences of nerve injury and recovery patterns after the BSSRO with or without genioplasty and sensory recovery patterns associated with the kind of nerve fiber.

This study aims to utilize DEA, analyze the efficiency of Korean coffee franchises, look into the factors that affect efficiency, and improve the efficiency of Korean coffee franchises. The main results of this study are as follows. First, according to CCR model standards, there are a total of 9 efficient coffee franchises and according to BCC model standards, there are a total of 12 efficient coffee franchises. A total of three of the inefficient DMUs were found to have a value of 1 for BCC, while the other 25 were found to be inefficient for both technology and scale. Second, of 28 franchises, 11 were analyzed to be decreasing return to scale and through future increased investments of optimum levels, business performance can be improved and efficiency can be enhanced. Analysis showed that 9 franchises appeared as CRS and it is most ideal to maintain the yield of future output elements at current levels and the work efficiency of 8 franchises in increasing returns to scale states expands as production scales increase according to specialization and role division and yield can relatively improve a lot. Third, the analysis of factors affecting the efficiency of franchises through the Tobit regression analysis showed that the number of franchises and operating periods had a positive (+) effect on efficiency. Based on this study, the efficiency of coffee franchises should be analyzed to establish strategies to maximize efficiency. Based on this study, the efficiency of coffee franchises should be analyzed to establish strategies to maximize efficiency.

A large portion of the Korean population has been exposed to toxic humidifier disinfectants (HDs), and considering that the majority of the victims are infants, the magnitude of the damage is expected to be considerably larger than what has currently been revealed. The current victims are voicing problems caused by various diseases, including but not limited to lung, upper respiratory tract, cardiovascular, kidney, musculoskeletal, eye, and skin diseases, etc. However, there has been difficulty in gaining validation for these health problems and identifying causal relationships due to lack of evidence proving that toxic HD is the specific causes of extrapulmonary diseases such as allergic rhinitis. Furthermore, the victims and bereaved families of the HD case have not received any support for psychological distress such as post-traumatic stress disorder, depression, feelings of injustice, and anger caused by the trauma. In addition, because the underlying mechanisms of the toxic materials within the HDs such as polyhexamethylene guanidine phosphate, poly(oxyalkylene guanidine) hydrochloride, chloromethylisothiazolinone /methylisothiazolinone have yet to be determined, the demand for information regarding the HD issue is growing. The victims of the HD cases require support that goes beyond financial aid for medical costs and living expenses. There is a desperate need for government-led integrated support centers that provide individualized support through health screenings; in other words, we need an integrated facility that provides the appropriate social support to allow the victims to recover their physical and mental health, so as to well prepare them to return to a normal life. The implementation of such a plan requires not only the close cooperation between those departments already directly involved such as the Ministry of Environment and the Ministry of Health and Welfare, but also active support on a national scale from pan-governmental consultative bodies.

Anyone who wants to install local ventilation system must obtain a permission from the Ministry of Employment and Labor even if he has permission from the Ministry of Environment. This is because not only the Atmospheric Environmental Protection Act, but also the manufacturing industry's hazardous risk prevention plan under Article 48 Clause 2 of the Industrial Safety and Health Act is to be submitted by 15 days before the construction. Under the current Environmental Protection Act, the Ministry of Environment regulates only the emission of pollutants from local exhaust ventilation systems into the atmosphere and the contents of workers' safety and health within industrial sites are managed by the Ministry of Employment and Labor. Even with the approval of the Ministry of Environment, the number of unsuccessful cases by the Ministry of Employment and Labor has increased, causing a growing discontent among the sites due to production delays and additional costs of improvement. In addition, local exhaust systems that are at greater risk of fire explosion have increased the risk of severe industrial accidents due to fire explosion. This is due to insufficient design of air volume, control speed, return speed, duct size, and risk of fire explosion. This is because the criteria and procedures for approval of local exhaust ventilation systems are similar, but the Industrial Safety and Health Act adds additional screening items for safety and safety of workers and fire and explosion. In this study, the Environment Ministry and the Employment and Labor Ministry seek to find a reasonable way to operate the system by comparing local exhaust ventilation system installation approval standards.

Objectives: This study identified the labor union associates' perception and participation status on SHEW and analyzed these two Constructs correlations with Safety and health education at work(SHEW) in manufacture and construction industries. Methods: Self-administered survey was successfully finished by 103 labor union associates (91 employed in 78 manufacturing companies and 12 employed in 12 constructing companies over 12 areas). Two questionnaires, survey direction slip, the official letter to ask survey participation from Korea Ministry of Labor, and a posted envelop to return were delivered to each workplace labor union office in conveniently selected companies. Most participants' companies were at least medium to large in manufacturing industry and most associates were men and married. A survey questionnaire examined demographic characteristics, SHEW status (participation status included), and perceptions of SHEW. Results: Overall, manufacturing companies had better infrastructures for SHEW, employer support for SHEW, and current educators' competencies than constructing companies. These infrastructures for SHEW were closely correlated with company labor union participation on SHEW and the correlation coefficients were greater than any other expectations or needs variables for SHEW. Conclusions: The primary strategies for better participation and support from labor union need to be developed in supporting for organizational infrastructures related to SHEW and strengthening safety and health education training programs for supervisors or educators at work.

Genetic variance and covariance components of the linear traits and the ordered categorical traits, that are usually observed as dichotomous or polychotomous outcomes, were simultaneously estimated in a multivariate threshold animal model with concepts of arbitrary underlying liability scales with Bayesian inference via Gibbs sampling algorithms. A multivariate threshold animal model in this study can be allowed in any combination of missing traits with assuming correlation among the traits considered. Gibbs sampling algorithms as a hierarchical Bayesian inference were used to get reliable point estimates to which marginal posterior means of parameters were assumed. Main point of this study is that the underlying values for the observations on the categorical traits sampled at previous round of iteration and the observations on the continuous traits can be considered to sample the underlying values for categorical data and continuous data with missing at current cycle (see appendix). This study also showed that the underlying variables for missing categorical data should be generated with taking into account for the correlated traits to satisfy the fully conditional posterior distributions of parameters although some of papers (Wang et al., 1997; VanTassell et al., 1998) presented that only the residual effects of missing traits were generated in same situation. In present study, Gibbs samplers for making the fully Bayesian inferences for unknown parameters of interests are played rolls with methodologies to enable the any combinations of the linear and categorical traits with missing observations. Moreover, two kinds of constraints to guarantee identifiability for the arbitrary underlying variables are shown with keeping the fully conditional posterior distributions of those parameters. Numerical example for a threshold animal model included the maternal and permanent environmental effects on a multiple ordered categorical trait as calving ease, a binary trait as non-return rate, and the other normally distributed trait, birth weight, is provided with simulation study.

Estuary sand bar of Namdaecheon Stream is located in Yangyang-gun, Gangwon-do in Korea. This unique place is situated between end of Namdaecheon Stream and East Sea. It is an important environment area of the global ecosystem from the transition zone of land and marine environments by forming a variety of coastal circumstance. Some endemic species should be protected which is appearing in the Namdaecheon Stream because of preservation for future generations. Especially, the salmon return to this stream as adults in order to breed which is more than 70 % of the salmon in Korea peninsular. The monitoring of estuary sand bar is need to analyze ecological environment and sustainable development with time. First of all we represents a different shape of estuary sand bar of Namdaecheon Stream from 1984 to 2015 using Landsat satellite imagery series. Particularly movement of the "tidal inlet" is most important factor to investigate the condition of the change for estuary sand bar. The location of tidal inlet is compared with precipitation, height of tide and oceanic current data according to time variation.

This study was carried out to improve the performance of heat recovery device attached to exhaust gas flue connected to combustion chamber of greenhouse heating system. Three different units were prepared far the comparison of heat recovery performance; A-type is exactly the same with the typical one fabricated for previous study of analyzing heat recovery performance in greenhouse heating system, other two types (B-type and C-type) modified from the control unit are different in the aspects of airflow direction (U-turn airflow) and pipe arrangement. The results are summarized as follows ; 1. In the case of Type-A, when considering the initial cost and current electricity fee required for system operation, it was expected that one or two years at most would be enough to return the whole cost invested. 2. Type-B and Type-C, basically different with Type-A in the aspect of airflow pattern, are not sensitive to the change of blower capacity with higher than 25m$^3$.min$^{-1}$ . Therefore, heat recovery performance was not improved so significantly with the increment of blower capacity. This was assumed to be that air flow resistance in high air capacity reduced the heat exchange rate as well. Never the less, compared with control unit, resultant heat recovery rate of Type-B and Type-C was improved by about 5％ and 13％, respectively 3. Desirable blower capacity of these heat recovery units experimented were expected to be about 25m$^3$.min$^{-1}$ , and at the proper blower capacity, U-turn airflow units showed better heat recovery performance than control unit. But, without regard to the type of heat recovery unit, it was recommended that comprehensive consideration of system's physical factors such as pipe arrangement density, unit pipe length and pipe thickness, etc., was required for the optimization of heat recovery system in the aspects of not only energy conservation but economic system design.
