This study is intended to figure out the effects of supervisors' transformational leadership on organizational culture and innovation in the fire fighting organization. To achieve this, a survey was carried out to fire officers from the National Emergency Management Agency and Seoul Metropolitan Fire & Disaster Headquarters. The results are as follows. First, the effect of supervisors' transformational leadership on organizational culture showed that supervisors' transformational leadership had an effect on group culture, norm culture and rational culture by sub-factors of organizational culture in the fire fighting organization. Second, the effect of organizational culture on organizational innovation showed that group culture and rational culture had an effect on organizational innovation. Third, the effect of supervisors' transformational leadership on organizational innovation showed that supervisors' transformational leadership had an effect on organizational innovation. As for findings stated above, supervisors' transformational leadership had positive effects on organizational culture and innovation in the fire fighting organization. Consequently, supervisors' energetic and change-seeking leader-ship for junior staffs with existing organization-and new generation-oriented new thinking system can contribute to rational culture and development-oriented innovation based on norms in the group.

Prospecting for energy and mineral resources is essential kind of public fundamentals that manage the nation's economy. Most explorations in the past were concentrated in the simple structural traps in relatively shallow depth. Due to their vast exploitation, recent history has shown that the emphasis in explorations has steadily shifted toward the subtle stratigraphic traps in deeper level. Increasing exploration for the subtle stratigraphic traps in deeper level requires precise correlation and assessment of deeply buried strata in the basin. However, the descriptive stratigraphic principles used for evaluation of the simple structural traps are limited to delineate the subtle stratigraphic traps in deeper depth. As this occurs, it is imperative to establish a new stratigrtaphic paradigm that allows a more sophisticated understanding on the basin stratigraphy. This study provides an exemplary application of integrated stratigraphic approach to defining basin stratigraphy of the Middle Ordovician Taebacksan Basin and the Cretaceous South Yellow Sea Basin, Korea. The integrated stratigraphic approach gives much better insight to unravel the stratigraphic response to tectonic evolution of the basins, which can be utilized for enhancing the efficiency of resources exploration and development in the basins. Thus, the integrated stratigraphic approach should be considered as a new stratigraphic norm that can improve the probability of success in any type of resources exploration and development project.

This study has investigated naturally occurring radioactive materials (N.O.R.M; $^{238}U$, $^{222}Rn$) for 353 drinking groundwater wells in metamorphic rock areas in Korea. Uranium concentrations ranged from N.D (not detected) to 563.56 ${\mu}g/L$ (median value, 0.68 ${\mu}g/L$) and radon concentrations ranged from 108 to 11,612 pCi/L (median value, 1,400 pCi/L). Uranium and radon concentrations in the groundwater generally are similar to USA with similar geological setting. Uranium concentrations in 9 wells (2.6%) exceeded 30 ${\mu}g/L$, which is the maximum contaminant level (MCL) by the US environmental protection agency (EPA), radon concentrations in 46 wells (13%) exceeded 4,000 pCi/L, which is the Alternative MCL (AMCL) by the US.EPA. The log-log correlation coefficient between uranium and radon was 0.32. The correlation coefficient between uranium and pH was 0.12 and the correlation coefficient between radon and temperature was -0.01. The correlation coefficient between uranium and $HCO_3$ was 0.09 and the correlation coefficient between uranium and Ca was 0.11. The median value of uranium was high Chung-Buk (1.78 ${\mu}g/L$), Gyeong-Buk (1.37 ${\mu}g/L$), In-Cheon (1.06 ${\mu}g/L$) for each province. On the other hand, the median value of radon was high In-Cheon (2,962 pCi/L), Chung-Buk (2,339 pCi/L), Jeon-Buk (2,165 pCi/L) for each province. Jeon-Buk for log-log correlation coefficient is the highest (0.63) among provinces.

The aim of this study is to analyze the effects of DVR(Driving Video Recorder) operation on decreasing the number of traffic accidents, the cost of traffic accident claim, and the behavioral change in drivers' driving. The data for this research are obtained from taxi drivers in Busan. For this, Structural Equation Model and two-way ANOVA are employed for empirical analysis. Overall results of this study show that the number of traffic accidents of 4 taxi corporations in Busan has decreased by average 32.7 percent after using DVRs. In addition, as to the cost of taxi accident claims, it is expected that the DVR operation has a considerable effect on economic benefits of taxi corporations. Moreover, this study could make clear the difference in behaviors between DVR users and non-users, and discriminate the positive and negative impacts of the DVR operation on the drivers' driving behavior. The study quantitatively examined the indirect impact of 'attitude', 'subject norm' and 'behavioral control' factors on planned 'behavior', and the direct impact of 'behavioral control' factor on the planned 'behavior'. This study suggests that they should add the video recoding function of DVRs when operation recorder(blackbox for the car) is obligatorily set up on cars for business by traffic security law.

This study was devised to elucidate whether soused shrimp exhibits a digestive action on boiled pork meats. and the mechanism by which sousing with a high concentration of sodium chloride preserves nutrients in foods for a prolonged pe\ulcornerriod. Protease was isolated from soused shrimp using a combination of ammonium sulfate fractionation. DEAE - cellulose ion exchange chromatography and gel filtra\ulcornertion. The isolated protease had specific activity of 1.560 units. 210 purification fo\ulcornerld with an yield of 38%. Its optimum pH and temperature were 8.0 and $43^{\circ}C$ respectively. The molecular weight of the enzyme was 35.000. The Km value of the enzyme for casein was 1.6 x $10^{-6}$ M The e=yme required the presence of cu\ulcornerpric ion to exhibit its full activity. Eighty eight percent of the enzyme activity was in\ulcornerhibited by 3.5M NaCI showing a reversibly linear decrease of the enzyme activity as NaCI concentration increased. The nature of the inhibition by NaCl was rever\ulcornersible and noncompetitive. The protease activity in soused shrimp was well preser\ulcornerved with the elapse of time at least in part due to NaCI induced suppression of autodigestion. The enzyme was denatured by acid easily. i.e. 1% of the original activity remained after staying at pH 2 for 10 minutes. which is within the norm\ulcorneral range of pH of the human stomach. Soused shrimp was observed to be one of those containing the highest protease activity compared with the other soused foo\ulcornerds such as soused oyster. squid. clam. and Pollack intestine with respect to spec\ulcornerific activities of dialized 1:4 whole homogenates(w/v) in 5 mM sodium phospha\ulcornerte - 2.4 mM j3 - mercaptoethanol buffer. pH 8.0. Casein and boiled meats including pork, beef, and chicken appeared to be the good substrates for the protease. Casein was the best. Therefore. the ingestion of boiled meats including pork together with soused sh\ulcornerrimp would help digestion of boiled pork in human not only by increasing appe\ulcornertite also by the direct proteolytic digestion of boiled meats by soused shrimp to\ulcorner some extent. And a high concentration of sodium chloride inhibited the protease activity reversibly in a remarkable degree, which ensued in a significant retardat\ulcornerion of autodigestion of protein in foods by proteases, and hereby contributed to the preservation of foods for an extended period.

The purpose of this study was to predict the factors which are related to the intention and behaviour for breast self-examination (BSE) of middle aged women using the theory of planned behavior (TPB). A survey using a structured questionnaire was conducted wih 217 middle aged women. BSE behaviour was assessed at 1-month follow-up. The overall fit of the structural model to the date was acceptable(${\chi}^2$=1246.6(p<.001), ${\chi}^2$/df=2.72, CFI=.831, TLI=.817, RMSEA=.089). The BSE behavior rate within one month was 56.2%. The TPB explained 43.9% of the variance in BSE intentions and 10.9% of the variance in BSE behavior. The subjective norm(${\beta}$=.364, p<.001) and the perceived behavioral control(${\beta}$=.553, p<.001) both positively influenced the behavioral intention, and the behavioral intention(${\beta}$=.768, p<.01) positively influenced the behavior. This study shows the model's applicability in explaining BSE behavior of middle aged women, and suggests that health intervention programs should focus on strengthening the intention for the promotion of BSE behavior.

The matter of cultivating entrepreneurship and will to start a business of university students majoring in agriculture and life sciences and college students majoring in agriculture as a future leader in the sector is a very important object of study. However, the discussion on entrepreneurship, establishment of a business and venture based on creative technology and innovative management have been scarcely had, because traditionally the majority of agricultural business has been a small-sized and simple business run by a small farmer. Education for starting an agricultural business in agriculture industry has been ignored even in the developed countries. ICT and AI(artificial intelligence)-based smart agriculture in the 4th Industrial Revolution Age is emerging as a new growth potential of our agriculture industry. Thus, the interest in farmers to start a business and venture agriculture is growing in the agriculture industry. Accordingly, the study draws the influence factors regarding the effect of the planned behavior of the university students who take part in the education course for starting an agricultural business and an agricultural venture business on entrepreneurship and will to start the business and conducts the empirical analysis. The businessmen who newly join the agriculture industry should perform the technical innovation and the creative business activities to be able to compete in the agriculture industry.

This study regarded irregular life styles such as nigh-shifts as contrary to the norm advised in the rules of Yang-saeng to analyze the problems brought about in relation to the concept of 'Yin-deficiency syndrome'. Yin-deficiency survey was given to sales workers on a big shopping mall in Seoul to compare the measurements of daytime workers to those of nigh-shift workers. The measurement of complaining symptoms related to Yin-deficiency of daytime workers and night-shift workers were compared, In comparison of the daytime workers and the night-shift workers, night-shift workers showed higher measurements than the daytime workers in the item of irritable fever on the five Hearts, flushing of the zygomatic region in the afternoon, tidal fever, dizziness, insomnia, yellow and scanty urination, and constipation. Especially tidal fever, insomnia, and constipation showed statistically significant difference. The total of ten items consisting of Yin-deficiency-related symptoms showed statistically significant high score in night-shift workers than the daytime workers. 'Factors for deficiency-type Heat' consisting of irritable fever on the five Hearts, flushing of the zygomatic region in the afternoon, tidal fever, and dried mouth and throat showed statistically significant high score in night-shift workers than the daytime workers. 'Accompanying factors' consisting of night sweats, emaciation, dizziness, insomnia, yellowish and scanty urination, and constipation also showed statistically and significantly high score in night-shift workers than the daytime workers. From the above results that night-shift workers show high degree of Yin-deficiency than daytime workers, and those overworking irregularly also show high degree of Yin-deficiency than those who work for adequate amount of time regularly implies that sitting up at night for work and sleeping at daytime, excessive work, and irregular life styles all function as high-risk factor for Yin-deficiency.

Background : Quality of professional nursing care is the most essential factor for survival and growth of nursing profession. Then, nursing professionals have responsibility for the evaluation of quality of professional nursing care. The purpose of this study was to develope an evaluation tool of nursing care for patients received gastrointestinal surgery with general anesthesia. This study was a primary work for the developement of a computer program for the evaluation of nursing care. Methods : This study was done through some consecutive steps. They were (1) Developement of items for the tool (2) Developement of an evaluation tool of nursing care quality for the G-I surgery patient (3) Test of reliability and validity of the tool. Two groups of experts and expert pannels who had much experience of the QA and the care of G-I surgery patients participated for developement of the items. 85 nursing records were used for the test of reliability and validity of the developed tool. The evaluation tools were developed with two types of scoring, norm-referenced tool and criterion-referenced tool. Results The system of items for tool was evaluation area evaluation item-indicator. There were 7evaluation areas which contained 32evaluation items which contained 7lindicators. Evaluation areas 1, 2, 3, 4 were for the evaluation of process and 5, 6, 7 were for the evaluation of outcome of nursing care for G-I surgery patient. For the test of interrator reliability, correlation coefficients of each scores of items and intragroup correlation coefficients were calculated. The average correlation coefficients between two rators were 0.65, 0.54 and the intragroup correlation coefficient were 0.99 and 1.00 by the types of scoring. The Cronbach alpha coefficients of the tools were 0.54 and 0.46 by the types of scoring. The average content validity index of the items was 0.95 from 4 pairs of experts. Because there were significant differences between some scores of quality of nursing care of 3 general hospitals regardless of the types of scoring, the tools could be thought to have some construct validity. And also, there were significant correlations between some scores of quality of nursing care and admission days and admission days after surgery regardless of the types of scoring, the tools could be thought to have predictive validity. Conclusion In this study, the evaluation tool of nursing care was developed for the very specified group of patient, G-I surgery patient. And the items were developed and tested by the experts of nursing practice. Because of these reasons, it was supposed that the tool could be used effectively in nursing pratice. And the procedures for the development and the test of the evaluation tool of nursing care in this study were supposed to be used for the developement of other tools.
