최근 데이터 용량이 급격히 증가하면서 대용량의 정보를 전달할 수 있는 광통신 시스템의 대역폭이 증가되고 있다. 이러한 대역폭의 문제를 해결하기 위하여 한 개의 광섬유에 여러 개의 파장을 사용함으로써 대역폭을 증가시키는 WDM 기술이 대두되었으며, 사용되는 파장의 간격이 점차 좁아지고 있다. 따라서 채널 간격이 매우 좁은 고밀도 WDM(DWDM)기술에는 일정한 간격으로 여러 채널들을 분리시키고 합치는 파장분할 다중소자가 필요하다. (중략)

This paper provides a theoretical approach to the New Zealand's Catch-Balancing Regime (CBR) with a reporting requirement under the Individual Transferable Quota (ITQ) system. The enforcement strategy depicted draws on recent literature regarding practical applications of the Revelation Principle. New Zealand's use of CBR-specific instruments such as deemed values, remains to be improved. However, some of its features can constitute a valuable example for regulators seeking to improve their methods of dealing with issues as bycatch or overfishing in order to maintain Total Allowable Catch (TAC) levels under emerging ITQ systems. The enforcement strategy analyzed has the potential to provide a more sustainable and efficient management of the fish stock, reduce discarding and stabilize monitoring costs, while improving the level of reporting compliance.

The purpose of this study was to identify construct validity and reliability of instrument for professionalism in physical therapy using developed by American Physical Therapy Association for 470 physical therapists. The corrected data was analysed using confirmatory factor analysis and internal consistency. Model of professionalism was adequate (p<.05) and consisted of 7 factors. Standardized coefficients of construct factor were followed by the integrity (${\beta}$=.93), professional duty (${\beta}$=.92), and compassion/caring (${\beta}$=.86). There were significant difference in professionalism by career(p<.05) but not significant difference by sex(p>.05). Also, the internal consistency for sub-factor of professionalism demonstrated adequate reliability of the measure (Cronbach ${\alpha}$=.80~.96). Because instrument for professionalism in physical therapy have a validity and reliability, it is useful for measuring professionalism in physical therapists.

The purpose of this study is to conduct the Korean translation and validity of the Unconditional Positive Self-Regard Scale(UPSR) that Patterson and Joseph(2006) originally developed based on the Rogerian person-centered theory. K-UPSR was adapted, modified and validated from the UPSR Scale. This study verified reliability and validity, and factor structure of K-UPSR. The preliminary study was proceeded with twelve adapted questions to 131 undergraduate and graduate students. As a result, three questions were deleted for the low reliability. The exploratory factor analysis of the nine questions showed two sub factors. The internal consistency reliability of nine questions with two sub factors was .89 in this study. The study was conducted by 419 male and female adults and verified confirmatory factor analysis and the validity. The study data was evaluated for the suitability of convergent and discriminant validity of K-UPSR. Through the correlation analysis of other five scales, the result was mostly corresponded to the preliminary study.

This study examined the optimization of hot-water extraction conditions for maximizing the total polyphenol compounds (TPC) extracted from amaranth leaf. The effects of three independent variables, including extraction temperature, extraction time and ethanol concentration on TPC were investigated using central composite design (CCD). The concentration of TPC increased with increased levels of extraction temperature and time. The extraction temperature and the ethanol concentration showed the significant effect on TPC production (p<0.05). The predicted values at the optimized condition were acceptable when compared to the experimental values ($R^2=0.9566$). The optimum extraction conditions were as follows: temperature of $90.1^{\circ}C$, time of 50 min and ethanol concentration of 61.6% (v/v) for the maximum TPC of 12.6 mg GAE/g DM.

The purpose of this study is to examine the psychometric properties of the Korean Children's Rejection Sensitivity Questionnaire (K-CRSQ). In order to investigate the reliability and validity of the K-CRSQ, the data were collected from 286 elementary students. The results are as follow : Internal consistency and test -retest reliability of the K-CRSQ were .83~.89, .72~.79, respectively. To test the convergent and discriminant validity, participants were separated into two samples and administered the K-CRSQ and ten validity indices. The correlation of K-CRSQ and validity indices scores suggested that the convergent and discriminant validity are high. High rejection sensitivity group revealed high score on intentional attribution, depression, anxiety, and aggression. In contrast, low rejection sensitivity group revealed high score on self-esteem, perceived competence, and social support. The results were compared with previous studies and the implication and limitation were discussed.

The development process from creative potential to realized talent is complex and non-linear. This feature of the process stands out more in the process of living a creative life in the long-term rather than in a situation to solve certain problems in the short-term. The purpose of this study is to develop Creativity Path Inventory (CPI) for undergraduate students based on Sawyer's Zigzag Model which is one of creative process theories and to verify reliability and validity of the inventory. Thus, reflecting the characteristics of each stage of the model, this study developed 88 items in 8 factors and finally confirmed 38 items in 7 factors through item analysis and verification process on construct validity. Internal consistency of a total of 38 items in CPI turned out to be .835, confirming the reliability of the inventory and goodness-of-fit index of the final model also demonstrated an appropriate result. CPI with verified reliability and validity will help enable people who want to manifest creativity in view of everyday creativity to realize self-improvement by self-reporting their strengths and weaknesses on their own.

The purposes of this study were to develop and validate Korean MHBT for identification of giftedness. MHBT in this study consists of KFT-HB and MHBT-5. MHBT-S was composed of 1) space presentation and thinking ability, space perception,. physics/technic tasks 2) affective domain; creativity, achievement motivation, desire of knowledge, social competence questionnaire 3) performance attitude questionnaire 4) interest questionnaire. The subject were 489 middle school students (1 or 2grade) in the education centers for gifted youth and general classes. Except a few subscales, internal consistent reliability was considered good. Korean MHBT discriminated well gifted students from general students in KFT-HB and some subtests of MHBT-5. As results, Korean MHBT in this study was expected to be a reliable and valid instrument for identification of korean gifted students.

The purpose of this study was to translate and examine the reliability and validity of Multidimensional Experiential Avoidance Questionnaire (MEAQ) developed by $G{\acute{a}}mez$, Chmielewski, Kotov, Ruggero, and Watson. 285 college students completed the MEAQ. Exploratory factor analysis supported the six factor structure of the 50 items. Internal consistency of 50 items was .91. 315 college students completed the MEAQ. Confirmatory factor analysis confirmed six factor structure of 50 items. 275 students of them completed also Acceptance-Action Questionnaire II, White Bear Suppression Inventory, Toronto Alexithymia Scale, Neuroticism, avoidant coping, CES-D, Beck Anxiety Inventory, Psychological Well-Being Scale, Satisfaction with Life Scale. Correlations between MEAQ and these scales supported the convergent, discriminant, and criterion-related validity.
