본 연구는 기업 근무자를 대상으로 정보지향성과 기술사업화능력이 기술성과에 미치는 영향에 관하여 분석하였다. 정보지향성은 정보기술능력, 정보관리능력, 정보행위 및 가치를 기술사업화능력은 제품화능력, 생산화능력, 마케팅능력을 하위변수로 구성하였고 기술축적역량을 조절변수로 하였다. 기업 직장인으로부터 수집한 온라인과 오프라인 설문지 349부에 대한 실증분석을 실시하였다. SPSS v22.0과 Process macro v3.4를 사용한 분석결과 첫째, 정보지향성과 기술성과는 유의적인 영향을 미치는 것으로 나타났고, 정보지향성이 기술사업화능력에 미치는 영향에서는 모두 유의적으로 나타났고, 기술사업화능력의 변수에서 제품화능력과 생산화능력에 미치는 영향력의 크기는 정보기술능력, 정보관리능력, 정보행위 및 가치의 순으로 나타났으나, 마케팅역량에 미치는 영향에서는 앞선 결과와 다르게 정보행위 및 가치, 정보관리능력, 정보기술능력의 순으로 나타났다. 둘째, 기술사업화능력이 기술성과에 미치는 영향에서 정보지향성과 독립적으로 기술사업화능력의 제품화능력, 생산화능력, 마케팅능력은 기술성과에 유의한 영향을 미치는 것으로 나타났다. 셋째, 정보기술능력과 정보관리능력은 기술성과에 유의적인 영향을 미치는 것으로 나타났으나, 정보행위 및 가치에서 제품화능력과 마케팅능력을 경유하는 간접효과는 유의적으로 나타났으나, 생산화능력을 경유하는 간접효과는 비유의적으로 나타났다. 넷째, 기술사업화능력의 하위변수 중 생산화능력과 기술축적 역량의 상호작용항만이 유의적으로 나타났고, 기술축적역량과 제품화능력, 마케팅능력은 비유의적으로 나타났다. 그러므로 생산화능력과 기술성과 간의 관계가 기술축적능력이 높은 기업이 낮은 기업보다 낮을 것이라고 해석할 수 있으며 후속 연구로는 다른 독립변수의 도입, 매개변수 및 조절변수가 도입된 모형을 통한 연구가 필요할 것으로 보인다.

The aim of this study was directed at exploring the possible use of muscle fiber characteristics as new selection traits for improving both porcine lean meat production and quality. A total of 174 (114 Yorkshire, 30 Landrace, and 30 Meishan) pigs were used for this study, and lean meat production ability was estimated by backfat thickness and loin eye area. The Longissimus dorsi muscle was taken in order to measure meat quality and muscle fiber characteristics. Due to the high correlations between total muscle fiber number and most of the performance traits, all pigs were classified into three groups (low, intermediate, or high) by total muscle fiber number using cluster analysis. The high group had the highest loin eye area (p<0.001). The meat quality traits were within normal ranges as reddish pink, firm, and nonexudative (RFN) pork, but the groups classified as intermediate and high had relatively large drip loss percentages (p<0.05), produced more than twice the amount of pale, soft, and exudative (PSE) pork as compared to the low group. The group with a high total muscle fiber number was further classified, based on type 2b fiber percentage, into low or high groups by cluster analysis. The results showed that the low type 2b fiber group had good loin eye area (p<0.05), small drip loss (p<0.05), and did not produce PSE pork. For these reasons, a high total muscle fiber number, with a low percentage of type 2b fibers, may be suitable in selecting for improvements in both lean meat production and meat quality.

This study was designed to estimate the ability of squalene treated mice to eliminate systemically infected bacteria and fungi and to elucidate the mechanism. As a result of measuring the ability to remove systemically infected bacteria and fungi, The ability of mice to remove the organism was found to increase in squalene treated mice when compared with control mice. And also the ability of phagocytic cells to produce Reactive Oxygen Intermediate(R.O.I.) increased in squalene treated mice. When the NADPH oxidase activity that make R.O.I. produce was measured, the activity increased in squalene treated mice, too. Therefore the good clearance of live organism in squalene treated mice is likely to relate to phagocytic cell activation. The activation of phagocytic cells might be mediated via the increased production of R.O.I. due to the increase of NADPH oxidase activity.

Acoustic telemetry is a useful method to investigate fish behavior and is widely used to obtain biological information. In this study, the detection ability of a mooring-type acoustic telemetry system and the seasonal changes were studied for survey design and data analysis. The system detection range was examined with an underwater noise model, and seasonal changes were estimated with a ray-tracing program and underwater temperature profile data. The field experiment was conducted with two sets of pingers and six receivers to estimate the difference in detection rate by installation depth and to compare the model estimate. Results indicated that the long-range detection ability of the acoustic telemetry system was significantly affected by underwater temperature. The detection rate rapidly decreased near the sea surface or bottom despite that the near-range Signal to noise ratio was sufficient.

The improvement of cooling ability for the air conditioner is the most efficient method of application of its system. Therefore, this study has been investigated the improvement of cooling ability for the air conditioner using automotive by attached of a thermoelectric module. According to the result of test, capacity of the thermoelectric module make temperature range from $-75^{\circ}C$ to $+300^{\circ}C$ possible to cooling and exothermic. In addtion to, the reduction effect of energy revealed and the effect of liquid hammer remained with safety by attached the thermoelectric module. It was found that the air conditioner system by attached thermoelectric module have better cooling ability than the air conditioner system of existing vehicle.

This study aimed at discovering whether Korean language learners who had never been exposed to Korean phones before could distinguish Korean phones and whether learners who had comparatively better ability of identifying phonetic differences displayed a better result in acquiring Korean phonemes. The study conducted two experiments on 25 learners. In Experiment I, an oddball test (ABX) was performed to investigate the learners' ability to discriminate Korean phones on the first day of the course. In Experiment II, an identification test was administered to analyze the ability of identifying Korean phones on the same learners after three weeks of language instruction. The results revealed that the true-beginner learners demonstrated different phonetic discrimination abilities, but these abilities did not seem to correlate with the rate of acquisition.

Objectives : This experiment study was performed to investigate the anti-inflammation and anti-oxidant effects of Indigo Naturalis(IN) and Rehmanniae Radix(RR) which were herbs for clearing heat. Methods : Anti-inflammation and anti-oxidation effects of IN and RR that were measured by the inhibitory ability of Nitric oxide(NO) production and the scavenging for 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical. Results : 1. IN and RR groups were not showed cell toxicity. 2. In the inhibitory ability of NO production, IN groups were better than RR groups, but there were no statistical significances among the groups. 3. In the scavenging for DPPH radical, IN groups were better than RR groups, but there were no statistical significances among the groups. Conclusions : These results showed that the IN group was better than the RR group in treating skin eruptions, especially those such as erythema, purple spot, papule, pustules which appear in acute inflammation.

Lactic acid bacteria that accumulated ${\gamma}-aminobutyric$ acid (GABA) in culture medium were screened to identify strains with high GAB A-producing ability. One strain, MS, which was isolated from kimchi, showed the highest GABA-producing ability among the screened strains. MS was identified as Lactobacillus buchneri based on Gram-staining, metabolic characteristics, and 16S rDNA sequence determination, Optimum culture conditions for GABA production were determined: MRS broth containing 5% MSG, 1% NaCl, and 1% glucose, at an initial pH of 5.0, the incubation temperature at $30^{\circ}C$ for 36 h. Under these conditions, MS produced GABA at a concentration of 251 mM with a 94% GABA conversion rate. Moreover, culture extracts of Lb. buchneri MS partially or completely protected neuronal cells against neurotoxicantinduced cell death.

The Korean cattle industry is important to farming households, the national economy, and the security of foodstuffs in Korea. Since Korean cattle have had inferior ability to produce meat, the Korean cattle industry aimed to improve the meat production ability and to increase numbers to meet the demand from the growing beef cattle market in Korea. This paper reviews the history of the Korean cattle industry and surveys the efforts devoted to improve genetic abilities of the Korean cattle. Discussed are current situations of the Korean cattle industry, projects related to improvement of Korean cattle, Korean cattle's genetic characteristics of economic traits, and some issues to deal with.
