This study shows that a sustainable competitive advantage and entrepreneurial characteristics are necessary for a software company to achieve competitive innovation and growth. This study investigates various software company characteristics and the effects of various company factors as its main research objectives. The data used in this research model were collected from software companies in South Korea. A total of 211 questionnaires were collected over a period of two months in 2013. EXCEL, AMOS, and SPSS were used to derive the study results. The hypothesis testing results of this study are as follows. First, a software company`s entrepreneurial innovativeness and risk-taking behaviors have a positive influence on software innovativeness. A greater sense of innovativeness and entrepreneurial orientation leads to a higher propensity to take risks in software development. Second, the characteristics of software innovativeness, and flexibility have a significant influence on software company performance. Innovation during the initial periods of software usage can create a high demand for improvements and new features, requiring a flexible software design. Finally, this study analyzes the software features of entrepreneurial characteristics and the influence of institutional factors on the characteristics of individual innovativeness and software development. Entrepreneurial characteristics can affect governmental or institutional support, policies, and legal frameworks to promote the role of software innovativeness. The results of this study imply that software companies can adopt an entrepreneurial approach to promote technology development and product development for achieving a competitive advantage in the industry. This study also analyzes the environmental factors that affect the software industry and their implications for policy makers.

Purpose : This study was a nonequivalent control group pretest-posttest research which aimed to analyze the effect of repetitive practice-based assessment on CPR performance of non-medic soldiers. The study intended to seek a CPR education method suitable for military. Methods : Experimental group, consisted of 38 participants, went through practice-based assessment with mannequins immediately after, and 2 weeks, 6 weeks, and 14 weeks after education and pre-assessment. Control group which consisted of 46 participants was given assessment once, 14 weeks after the education and pre-assessment. The data was analyzed using IBM SPSS 20.0, with descriptive statistics, chi-square test, independent t-test and ANCOVA. Results : The experimental group had a higher ratio of people who have had CPR education in the past (p=.001) but the control group showed better performance (p<.05). Repetition of intensive assessment resulted in increase of experimental group`s performance score as the group progressed through assessments (p<.01). Control group showed significant decrease in score (p<.01). Conclusion : Repetitive practice-based assessment has educational effects on improving participants` performance. Re-education must be provided within at most 14 weeks and should focus on practicing.

동백나무(Camellia japonica L.) 낙엽의 분해와 영양원소의 동태

차상섭 ( Sangsub Cha ),이경의 ( Kyung Eui Lee ),이상훈 ( Sang Hoon Lee ),최문종 ( Moonjong Choi ),심재국 ( Jae Kuk Shim ) 한국환경생태학회 2016 한국환경생태학회지 Vol.30 No.1

낙엽은 육상 생태계에서 영양원소의 주요 원천이며, 낙엽의 분해는 토양의 비옥도를 유지하고, 식물의 생장을 위한 영양원소의 방출 뿐 아니라 이산화탄소의 배출을 조절하는 생물계에서 가장 중요한 과정 중 하나이다. 본 연구는 지구온난화로 인해 그 분포역의 확대가 예상되는 상록활엽수인 동백나무를 대상으로 낙엽의 분해율 및 분해과정에 따른 영양원소의 함량 변화를 파악하기 위해 진행되었다. 실험은 전라남도 완도군 주도 상록활엽수림에서 2011년 12월부터 2013년 12월까지 731일간에 걸쳐 수행되었다. 동백나무 낙엽은 기타 상록활엽수 낙엽에 비해 작고 두꺼우며 단단한 재질을 가지고 있고, 비교적 높은 수용성물질과 셀룰로즈, 리그닌의 함량을 나타내었다. 분해 시작 후, 731일 경과 된 동백나무 낙엽의 잔존율은 42.6%이고 분해상수(k)는 0.427으로 나타났다. 동백나무 낙엽의 탄소 함량은 44.6% 를 나타내었고, 분해과정에 따른 탄소의 잔존량은 낙엽 잔존량의 변화와 거의 일치하는 경향을 나타내었다. 질소와 인의 초기 함량은 각각 0.47%와 324.7mg/g을 나타내었다. 질소의 잔존량은 분해 초기 증가하여 최고 1.66배까지 증가하였지만, 점차 감소하여 731일 후 초기양의 1.18배를 나타내었다. 인의 경우 최고 1.64배까지 증가하였고 731일후 1.15배를 나타내었다. 동백나무 낙엽의 칼슘, 칼륨, 마그네슘, 나트륨 잔존량은 분해과정에 따라 감소하는 경향을 나타내었다. 칼륨의 경우 빠르게 감소하여 8.9%의 잔존율을 보였다. C/N, C/P 초기 비율은 각각 94.87과 1368.5로 나타났지만, 분해가 진행됨에 따라 현저하게 낮아지는 경향을 나타내었다. 이는 질소와 인의 함량이 초기 함량에 비해최대 2.78배와 2.68배까지 증가하였기 때문이다. 본 연구의 결과 동백나무의 낙엽은 조사기간 동안에 질소와 인에서는 부동화가, 나머지 원소에서는 무기화가 진행되는 것을 확인하였다. Litter fall is a source of nutrients and carbon transfer in terrestrial ecosystems. Litter decomposition provides nutrients needed for plant growth, sustains soil fertility, and supplies CO2 to the atmosphere. We collected the leaf litter of evergreen broadleaf tree, Camellia japonica L., and carried out a decomposition experiment using the litterbag method in Ju-do, Wando-gun, Korea for 731 days from Dec 25, 2011 to Dec 25, 2013. The leaf litter of C. japonica remained 42.6% of the initial litter mass after experiment. The decay constant (k) of C. japonica leaf litter was 0.427 yr-1. The carbon content of C. japonica leaf litter was 44.6%, and the remaining carbon content during the decomposition tended to coincide with the changes in litter mass. The initial nitrogen and phosphorus content was 0.47% and 324.7 mg/g, respectively. The remaining N in decaying litter increased 1.66-fold in the early decomposition stage, then gradually decreased to 1.18-fold after 731 days. The content of P showed the highest value (1.64-fold of initial content) after 456 days, which then fell to a 1.15-fold after 731 days. The remaining Ca, K, Mg and Na content in C. japonica leaf litter tended to decrease during decomposition. The remaining K showed a remaining mass of 8.9% as a result of rapid reduction. The initial C/N and C/P ratio of C. japonica leaf litter was 94.87 and 1368.5, respectively. However, it tended to decrease as decomposition progressed because of the immobilization of N and P (2.78 and 2.68-fold of initial content, respectively) during the leaf litter decaying. The study results showed that N and P was immobilized and other nutrients was mineralized in C. japonica leaf litter during experimental period.

Objectives:This study was designed to develop the Korean version of Alcohol Use Disorders Identification Test (AUDITK) and AUDIT Alcohol Consumption Questions (AUDIT-CK) which is composed of the first 3 questions of AUDIT, a screening tool for the alcohol use disorder. Methods:The translation, including back translation procedure, was carried out, keeping the basic structure of AUDIT. AUDIT-K, AUDITC-K, Korean version of Michigan Alcoholism Screening Test (MAST-K), Korean version of CAGE (CAGE-K) and clinical diagnosis were administered to 43 alcohol use disorder patients and 43 non-alcohol use disorder control subjects. The reliability and validity of AUDIT-K and AUDIT-C-K were evaluated. The sensitivity and specificity for each cut-off point of AUDITK and AUDIT-C-K were calculated and the Receiver Operating Characteristic (ROC) curve analysis was done to get their optimal cut-off points. Diagnostic efficiency of AUDITK and AUDIT-C-K was evaluated by ROC curve analysis. Results:AUDIT-K was found to have significantly high internal consistency, and test-retest reliability. The correlation coefficients of AUDIT-K with MAST-K and CAGE-K were 0.86 and 0.80, respectively, and significant correlation was shown. Its optimal cut-off point was estimated as 12, and the sensitivity and specificity were 0.84 and 0.86, respectively. The correlation coefficients of AUDIT-C-K with MAST-K and CAGE-K were 0.60 and 0.56, respectively. Its optimal cut-off point was estimated as 8, and the sensitivity and specificity were 0.95 and 0.77, respectively. The ROC curve analysis indicated that the diagnostic efficiency of AUDIT-K and AUDIT-C-K was comparable with that of MAST-K and superior to that of CAGE-K. Conclusion:AUDIT-K and AUDIT-C-K have not only high reliability and validity, but also usefulness as a screening instrument for alcohol use disorder.
