Furniture is very important in our lives. Especially traditional wood furniture of Korea has been developed practically in the area of form, compositions, manufacturing technique and etc because of the rapid environmental changes. Jang Sung has a very efficient geographical characters to get the adequate timbers for furniture. And the late Mr Seol SeokCheol had devoted all his life to out-and-out artisan spirit for the purpose of korean wood furniture manufacturing. In this paper, l try to explain regional and cultural characteristics of JS, special designs for wood furniture of JS, manufacturing process of traditional wood furniture, especially in the center of his works. Tradition is an essential power to a country and a race. Now we are living living in the state-of-art age and we share all the cultures and merchandise globally but nevertheless, a nation and a race who has a unique tradition is still a cultural advanced country and these works of our ancestors are the best souvenir for the tourists. So we have to memorize these facts and we will have to raise and develop our power of traditional cultures, including from the traditional wood furniture.

Purpose: The purpose of the study was to evaluate how advanced practice nurses (APNs) recognized their work by analyzing nursing outcomes. The ultimate goal was to examine the utility of APNs by connecting their work to the outcomes. Methods: Cross-sectional survey was conducted to collect the data from 59 APNs in a tertiary hospital lovated in Seoul, Korea. The questionnaire with 84 outcome indicators for advanced practice nurses was used. Descriptive statistics were used to analyze the data. Results: Among 84 outcome indicators, 11 indicators were associated with the work of APNs. Majority of these findings were included in the categories of clinical results and satisfaction. Items identified to be associated with the work of APNs were different among oncology nursing area, surgical speciality area, emergency care area, and critical care area. Conclusion: The results of the study indicated that the works of APNs were relevant to education/counseling/training and interpersonal relationship with other health professionals. The results of the study could be helpful to delineate the work characteristics of APNs and increase the utility of APNs in Korea where roles of APNs are not yet clearly delineated in most clinical settings.

This study presented the strength of the materials and parts for smart distribution board fabrication, and developed a work operation process chart for smart distribution board fabrication. This work operation process chart for smart distribution board fabrication complied with SPS-KEMC regulations, and the applicable range and object are less than 1,000 V and 1,000 Hz for the AC distribution board and less than 1,500 V for the DC distribution board. The power supply is 3 phase 4 wires ($3{\Phi}$ 4W), divided into a single phase circuit and a 3 phase circuit. In addition, the circuit was configured so that the leakage current flowing through the distribution line of the load could be monitored in real time by using the sensor module installed at the rear end of the circuit breaker. Therefore, the administrator can easily find the risk factor of the load since engineer can check the leakage current of each distribution line. In addition, if a leakage current greater than standard value flows, it is possible to generate an alarm against a short circuit and cut off the leakage current. The work operation process chart for the smart distribution board fabrication consists of the following steps: raw and subsidiary materials, sheet metal work, tube making, welding, painting, busbar fabrication, assembly and wiring, product inspection, shipment, etc. Moreover, symbols, ${\Delta}$, ${\nabla}$, ${\bigcirc}$, ${\Rightarrow}$, etc. were used according to the type of work and work progress so that workers can easily understand the progress of the work.

This study is evaluation of shift-workers' sleep and social life related to hospital workers' performance and health. We researched shiftworkers' sleep, sleeping quality and social relations using a questionnaire method to shiftworkplace scattered Daejeon and Chungnam province. The results of shiftworkers' sleep are differ from habitual sleep. Social participations of shiftworkerse are interfered partially because of shiftwork. In preference, shiftworker preferred health to others because of physical load of shiftworks. Through result of this study about sleep and social life style, we hope to derive reduction methods of shift work fatigue and education for improvement of employers, for example an physiological and psychological accordance method, an health problem solving method and an social accordance method, etc.

This research focused on the priotity decision for establishment sriteria on the effects which environmental sculptures in urban area. The analysis performed in this study used the AHP(Analytic Hierarchy Process) that is recognized as a useful decision-making tool to select and evaluate alternatives through pairwise comparison in the context of hierarchical decision structure. The results obtained from the analysis drawn by collecting the professional opinions of 5 experts for environmental sculptures are as follows: 1. The orders of establish criteria priorities on environmental sculptures were harmony of environment> symbol> public> function. The harmony of environment was the most important priority because it showed the highest weight of criteria. 2. The alternative priorities of environmental sculptures were the meaning of work>setting place> social contribution> physical quality .The meaning of work showed the highest change in the weight of alternative. 3.The sensitivity analysis of environmental sculptures demonstrated that the rate of change in the alternative priorities of the public was stabilized although the criteria importance varied, while the harmony of environment, the symbol intimated and function of priorities has their rates of weight changed if the criteria priorities were high.

In this study we tried to examine the efficiency of the agricultural convenient tool (put-on-style-stool) by observing subjects'physiological responses. For this we measured subjects' heart rate, oxygen consumption, blood lactate level, mean skin temperature and rectal temperature. The results of this study are as follows; Heart rate was 75$\pm$2 beats/min with the put-on-style-stool and 78$\pm$2 beats/min without it (P＜0.01). Oxygen consumption was 3.88$\pm$1.90 $m\ell$/kg/min with the Put-on-style-stool and 5. 06$\pm$0.40 $m\ell$/kg/min without it (P＜0.05). Blood lactate level was 2.39$\pm$0.64 mmol with the put-on-style-stool and 3.38$\pm$0.45 mmol without it (P＜0.05). Mean skin temperature was lower but rectal temperature was higher with than without the put- on - style - stool (P＜0.05 and P＜0.01 respectively) So, using the put-on-style-stool was evaluated positively in farmer's work.

When several service providers want to work together with only one master key, they need to properly distribute the key to participants who come in for the co-work business and then securely manage the distributed keys. This paper describes the system that can efficiently and securely manage the master key on the basis of the secret sharing scheme that can reconstruct original secret information as the necessity of reconstructing original secret arises. The proposed system can distribute secret information to several groups and also redistribute the secret to subgroup in proportion to the participant's security level using smart card-based (t, t)-(k, n)-threshold secret scheme for securely keeping secret information and authentication of participant's identification.
