This paper examines the effects of IT technology capital and R&D stock's variation on the growth of Korea's industries with the empirical approaches. We analyze the Granger causality and Impulse response function analysis among the Korea's industrial real output, IT technology capital, and R&D stocks. When it comes to this research conclusion, we know that IT technology capital and R&D stock's shocks affect the growth of Korea's industrial sector in terms of increasing in the real output growth rate.

Objective: To study the etiology of primary amenorrhea in 19-aged woman. Materials and Methods: Case report. Results: I found that there were not gonads and organ of mullerian ducts origin on diagnostic laparoscopy. She was normal 46XX on chromosomal study and normal external genitalia except short vaginal canal. Conclusion: It is very rare that absent gonads and lack of mullerian ducts with 46XX female and primary amenorrhea.

In goats fed on dry forage twice a day, an esophageal fistula was used to investigate the physiological factors present in the marked suppression of dry forage intake that occurs after 40 min of feeding. The animals used in this study were five large-type male esophageal- and ruminal-fistulated goats. Roughly crushed alfalfa hay cubes with any large remaining chunks removed were used as feed for this research. The study was conducted under both normal feeding conditions (NFC) and sham feeding conditions (SFC). In the NFC control, the esophageal fistulae were closed by plugs and the animals ate dry forage in the normal manner. In the SFC treatment, before starting the experiment the plugs for closing the esophageal fistula were removed and the cannulae for collecting boluses were fitted into the fistulae. Therefore, the esophageal boluses were removed via an esophageal fistula before they entered the rumen. In the NFC control, eating rates sharply decreased in the first 40 min of feeding and were subsequently maintained at low levels. However, eating rates in the SFC treatment remained high after 40 min of the feeding period had elapsed and the goats ate continuously during the 2 h feeding period. In comparison with the NFC control ($1,794{\pm}203.80\;g$/2 h), cumulative dry forage intake in the SFC treatment ($3,182{\pm}381.69\;g$/2 h) was 77.4% greater (p<0.05) upon conclusion of the 2 h feeding period. In the SFC treatment, cumulative bolus output ($6,804{\pm}469.92\;g$/2 h) was about twofold the cumulative dry forage intake due to cumulative salivary secretion volume ($3,622{\pm}104.13\;g$/2 h) upon conclusion of the 2 h feeding period. The result indicates that large amounts of secreted saliva during dry forage feeding act in conjunction with consumed feed to form the ruminal load responsible for ruminal distension. The increased plasma total protein concentrations were higher in the SFC treatment than in the NFC control. However, plasma and ruminal fluid osmolalities increased in the NFC control during and after feeding but were mostly unchanged in the SFC treatment. In comparison with the NFC control ($3,440{\pm}548.04\;g$/30 min), thirst level in the SFC treatment ($1,360{\pm}467.02\;g$/30 min) was 60.5% significantly less (p<0.05) upon conclusion of the 30 min drinking period. The results of the present study indicate that In the second hour of the 2 h feeding period, dry forage intake is regulated by factors produced when boluses enter the rumen.

본 연구에서는 시큐리티 요원의 복리후생이 조직몰입 및 직무만족에 미치는 영향을 규명하는데 목적이 있다. 이러한 목적을 달성하기 위해 서울 및 경기지역 내에 위치한 시큐리티 관련 회사에 재직중인 288명 시큐리티 요원들에게 복리후생, 조직몰입, 직무만족의 척도를 통해 자료를 수집하였다. 수집된 자료는 SPSS 18.0과 AMOS 18.0의 하위 프로그램인 기술통계, 탐색적 및 확인적 요인분석, 신뢰도분석, 변량분석, 상관분석, 공변량 분석을 이용하였으며 이에 대한 분석결과를 토대로 다음과 같은 결론을 얻었다. 첫째, 개인적 특성에 따라 시큐리티 요원들의 복리후생, 조직몰입, 직무만족에 차이가 나타났다. 둘째, 시큐리티 요원들의 복리후생(문화지원, 시설지원, 경제지원, 생활지원)은 조직몰입에 정적(+)인 영향을 미치는 것으로 나타나 시큐리티 직원의 조직몰입 증가는 복리후생이 중요한 요인으로 작용될 수 있다는 결론을 얻었다. 셋째, 시큐리티 요원들의 복리후생(문화지원, 시설지원, 경제지원, 생활지원)은 직무만족에 정적(+)인 영향을 보여 직무만족을 높이는데 복리후생을 만족하게 하는 것이 하나의 방안이라는 결론을 얻었다.

In nuclear power plant, the main control room(MCR) plays a leading and important role, so it is the core to have its design well operater-centered, both physically and cognitively. This paper especially analyzes focusing on lighting MCR environment and shows alternatives. It will lead to improve work efficiency and to care operator's sight. In conclusion, reducing operator's stress, fatigue and increasing safety, comfort.

This paper analyzes economic efficiency of strawberries and tomatoes farms using the data envelopment analysis (DEA). We examine how production characteristics and farm size affect overall efficiency (OE), allocative efficiency (AE), and technological efficiency (TE). We also survey sample farm households from the Farm Income Investigation database of Rural Development Administration to investigate management and cultivation techniques and to analyze economic efficiency by technique. Implications for improving efficiency are suggested in the conclusion.

For accurate interpretation, ECG signal is measured by using 12 leads method. We look shape of Measured ECG signal and decide whether interpretation is accurate or not. In this paper, we propose new effective fuzzy decision system which uses fuzzy rules and membership functions for more accurate of ECG wave. We used PR interval, QRS interval and QRS axis as conditional variables for designing fuzzy rules. And decision rule of conclusion variable is determined by (sinus rhythm), (sinus rhythm+left deviation), (sinus rhythm+right deviation) and (sinus rhythm+negative axis). Experimental results showed our system made numerically easy decision possible and had advantage of simple design method.

We met the continued population growth, contamination of both surface and groundwaters, deficiency of water resources, and increase of water demand. Wastewater reclamation and reusing system are important facilities in water resources planning aspect. The required water quality for reclamed wastewater varies with each application. This study was conducted to examine the possibilities of the wastewater reclamation and reusing on milk manufacturing wastewater. Biofiltration could reduce the COD$_{Cr}$, NH$_{3}$-N. Turbidty was reduced highly by coagulation. In conclusion, we identified the possibilities of wastewater reclamation and reusing on milk manufacturing wastewater's by biological activated carbon filter.

We introduce a new percentile envelope for diagnosing supernormality in regression analysis. Furthermore, we compare this percentile envelope, which is much simpler and easier, with Atkinson's and Flack and Flores' envelopes. Using percentile envelope, we investigate characteristics of normal probability plots with envelope for error distributions when supernormality is occurred. We give cautions that test result for normality assumption of errors can be reached the wrong conclusion by supernormality.
