The present study classified groups based on latent profile of self-determination motivation(amotivation, external motivation, intrinsic motivation), and examined the determinants for each group. The data was collected through panel data of Korea Education Longitudinal Study(KELS), total 5,459 participants who answered questionnaires of self-determination motivation of two times both second grade of middle school and second grade of high school. To identify the change motivational type, standardized residual was conducted using SPSS 17.0., and the latent classes for the change of motivational type was investigated using M-Plus in the frame work of Latent Profile Analysis(LPA). The results indicated that five groups(increase of self-determination, self-determination maintenance, self-determination developmental delay, elf-determination confusion, decrease of self-determination group) were classified based on latent profile. In addition, parental control, academic self-concept, teacher-student relationship, test anxiety, avoidance orientation, gender, father's education, and income were significantly related to each group. Lastly, the implications for directions of the adolescent counseling, limitations and future research are discussed.

Intrusion prevention systems (IPS) are important solution about solved problems for inside system security or outsider attacks. When introduce this system, first consideration item is secured rather than multiple function. Colored Petri Nets (CPNs) used that in order to secured verification for user authentication function of intrusion prevention system security model. CPNs is a graphical modeling language suitable for modeling distributed, concurrent, deterministic or non-deterministic systems with synchronous. Like these CPNs was expressed every possible state and occurrence graph. Secured of IPS security model was verified because expression every state using CPN tool and as a result of analyzing the occurrence graph was without a loop or interruption.

본 연구는 소비자가 다른 사람과 차별되며 특별하게 지각되고자 하는 성향을 나타내는 소비자의독특성 욕구와 의복에 대한 관심이 브랜드 인식, 브랜드 충성, 및 구매의도와의 어떠한 관계를 지니고 있는지를 밝히고자 하였다. 특히 이러한 관계에 있어 문화간의 차이가 있는지를 알아보기 위하여 한국과 미국 소비자를 대상으로, 소비자특성이 구매의사결정에 미치는 과정의 모형을 검증한 후, 두 모형을 비교 분석하였다. 자료는 설문지를 사용하여 한국과 미국대학생을 중심으로 수집되었으며, 응답이 부정확하거나 불성실한 설문지를 제외하고, 총 485부-한국 271부와 미국 214부-만이 최종 자료 분석에 사용되었다 본 연구에서 사용한 통계분석방법으로 신뢰도 검증을 위하여 SPSS 11.0을 이용하여 신뢰도 계수를 구하였으며, Prelis 2와 Lisrel 8.53으로 확인적 요인분석 및 모형검증을 실시하였다. 한국과 미국소비자의 선택친 모형을 비교한 결과, 전반적인 모형의 구조에도 차이를 보였을 뿐 아니라 각 변수간의 영향력에도 차이가 있음을 나타냈다. 소비자의 독특성 욕구의 하위차원인 '독창적 선택'과 '브랜드 충성도'의 관계는 두 그룹간의 반대의 성향을 보였으며, '비대증적 선택'과 '브랜드 인식'도 또한 한국 소비자는 정의 관계를 보인 반면, 미국소비자는 부의 관계를 나타냈다. 이와 더불어 유사성을 회피하려는 한국소비자들은 브랜드에 충성하는 경향이 있는 반면, 미국소비자들은 브랜드 인식도가 높은 것으로 나타나 두 문화간의 차이가 있음을 뒷받침하였다. '브랜드 충성도'는 두 집단 모두 '구매의도'에 상대적으로 높은 영향을 미치는 것으로 나타났다.

The purpose of this study is to verify the relationship between consumer 's self - determination psychological needs (autonomy, competence, and relevance) related to fair trade and brand equity related to fair trade products through empirical analysis. It is meaningful that it is linked to strategic brand management based on consumer need satisfaction. As a result of empirical analysis of this study, Fair Trade attitude plays an important role in the relationship between self - determination psychological desire and brand equity. Especially, Consumer need Satisfaction with competence was found to be a strategically important construct. Based on the results of this study, it is expected to provide important implications for future strategic management of brand equity related to Fair Trade products.

Despite the advantage of unlimited access, there are insufficient studies for the accuracy and stability of FKP that blocks the spread of the system for various applications. Therefore, we performed a long-term analysis from continuous real-time positioning, and investigated the error characteristics dependent on the size and the surrounding environment. The FKP shows significant changes in the positioning accuracy at different times of day, where the accuracy during daytime is worse than that of nighttime. In addition, the size and deviation of FKP correction may change with the ionospheric conditions, and high correlation between ambiguity resolution rate and the deviation of correction was observed. The receivers continuously request the correction information in order to cope with sudden variability of ionosphere. On the other hand, the correction information was not received up to an hour in case of stable ionospheric condition. It is noteworthy that the outliers of FKP are clustered in their position with some biases. Since several meters of errors can be occurred for kinematic positioning with FKP, therefore, it is necessary to make appropriate preparation for real-time applications.

This study was conducted to verify the effect of integrated therapy program on the self-esteem, self-expression, and sexual self-determination of sexually abused women with intellectual disabilities. The subjects of this study were 8 victims who were referred to the Sexual Violence Relief Center for women with intellectual disabilities in K-area. The effectiveness of the program was evaluated to statistical significance though the pre- and post-test using the SPSS Win 25.0 program. The integrated therapy program significantly improved the self-esteem of victims(t=-4.183, p<0.001). Self-expression was significantly improved(t=-5.103, p<0.001). It was also observed that the change in behavior was positively reinforced in the sexual self-determination(t=-26.346, p<0.001). The results of this study suggest that integrated therapy program should be actively used for psychological and emotional healing of sexual assault victims with intellectual disabilities.

하천에 포함되는 각종 시설물을 설계하는데 있어 기준이 되는 하천설계기준에는 대부분 하천의 대표유속을 통해 시설물의 규모와 형태를 결정하는 공식이 제시되어 있다. 이러한 대표유속의 경우 대부분 평균유속을 사용하고 있으며 하천의 형태와 시설 등에 의한 영향으로 국부적으로 유속이 증가하는 경우 유속보정계수를 이용하여 평균유속을 보정하여 사용한다. 이러한 유속보정계수는 만곡, 세굴, 저수로 간섭, 근고공 및 수제공 등에 적용되며 본 연구에서는 하천의 곡률에 의한 유속보정계수를 수치모의를 통해 검증하고자 한다. 하도 중심의 곡률반경의 변화에 따른 평균 유속과 국부유속의 차이를 계산하고 기 제시된 보정계수 산정식과 비교하여 산정식의 활용성에 대한 검증을 수행하였다. 본 연구를 통해 유속보정계수의 중요성과 활용성을 제고하고 하천시설물의 설계 시에 평균유속이 아닌 보정된 대표유속을 활용한다면 하천시설물에 대한 안전성을 향상시킬 수 있을 것으로 예상된다.

The purpose of this study was to examine the relationship between family strength and career decision-making difficulties and the mediating effect or career self-regulation. The results of the present study suggested the significance of family strength and career self-regulation in understanding career decision-making difficulties. With 172 Korean college students, there were both significant direct and indirect effects from family strength to career decision-making difficulties. Specifically, the mediation roles of career self-regulation was confirmed. Comparing the partial mediation model with full mediation model, the partial mediation model fits better with the data. These results have significant clinical implication that counseling practitioners need to address the possible influence of family strength on college student's perceived difficulties in career decision-making process and to assist students develop appropriate level of competencies of regulating one's emotion, thoughts, and behavior related to career problems.

It is highly required to evaluate the economic value of technology in many decision making of the technology management area, for example, technology acquisition, transfer, and investments. Also evaluating the performance of R&D objectively is very important subject in the public side. So, developing the objective technology evaluation system has much usefulness in practice. In many studies, the patent information has been suggested to the valid measurement for evaluation of technology. The purpose of this study is to explore the validity of patent information as a measurement of technology evaluation.

Data Envelopment Analysis(DEA), a non-parametric productivity analysis tool, has become an accepted approach for assessing efficiency in a wide range of fields. Despite of its extensive applications and merits, some features of DEA remain bothersome. DEA offers no guideline about to which direction relatively inefficient DMUs improve since a reference set of an inefficient DMU, several efficient DMUs, hardly provides a stepwise path for improving the efficiency of the inefficient DMU. In this paper, we aim to show that DEA can be used to evaluate the efficiency of life insurance companies while overcoming its limitation with the aids of machine learning methods.
