Leadership is a critical factor for success or failure of an organization. Project managers in construction projects are 'field CEO' so their leadership affects performance of the projects. The objectives of this study is to evaluate the leadership of project managers and to analyse its major characteristics. The LBDQ(Leader Behavior Description Questionnaire) technique was used to evaluate and identify types of leadership of project managers from 'heaven' and 'hell'. Relationships between leadership and performance of the projects were also discussed.

In this paper, we propose and design an NCS-based job matching system for individuals with disabilities. This system allows users with disabilities to access it, input basic information (personal and disability-related details), and take a simple test related to job performance. The system then provides NCS job-related information appropriate to their type and degree of disability. To effectively link various NCS-based jobs, it is essential to consider the degree of disability for each type of disability. However, most evaluation tools target specific types of disabilities or assess the vocational abilities of individuals with disabilities in a limited manner, focusing only on cognitive levels or certain physical functions. This makes it challenging to apply these tools to an NCS-based job matching system for individuals with disabilities. Therefore, in this paper, we utilize the ICF coresets for VR to assess the cognitive levels or physical functions required for performing specific jobs. Additionally, we use the NCS vocational competency evaluation tools to determine the levels of vocational competencies required for performing specific jobs. By doing so, we match NCS-based jobs according to the type and degree of disability. The proposed NCS-based job matching system relies on the user's interaction with the system, which may pose challenges for visually impaired individuals or those with intellectual and autism spectrum disabilities who have low literacy levels. Enhancing the accessibility of this system could enable individuals with disabilities to receive recommendations for NCS-based jobs that suit their vocational abilities.

Objective：This study was performed in order to develop a measuring instrument for assessing and predicting delinquent behavior of the adolescents in Korea. Methods：This study was methodological research for developing a questionnaire for measuring delinquent behavior. Through the relevant literature review and personal interview using open-ended question with 12 adolescents in schools, outpatient basis and the juvenile corrective institutions, the author developed a pre-questionnaire with 31 items for assessing delinquent behavior among delinquentprone adolescents. Statistical method employed were test-retest reliability and Cronbach's alpha coefficient for testing reliability and factor analysis for testing validity of this questionnaire, and t-test for mean difference between student adolescents and delinquent adolescents, using SAS program. Subject served for this study consisted of 2,177 adolescents including 1,206 students and 971 delinquent adolescents by proportional stratified random sampling method. Results：1) Three stable factors were emerged and these contributed 52.2% of the variance in the total score. All 31 items loaded above .40 on each factor. 2) Factor I was named as antisocial delinquent behavior(17 items), factor II was named as aggressive delinquent behavior(8 items), and factor III was named as psychopathic delinquent behavior(6 items). 3) Comparison of these 3 factors between student adolescents and delinquent adolescents showed that there was a significant difference in factor Ⅰ(t=-42.91(student), -41.71(delinquent), p=.0001), factor II(t=-34.10(student), -35.72(delinquent), p=.0001), factor III(t=-14.24(student), -14.26 (delinquent), p=.0000), and total score(t=37.02(student), -36.38(delinquent), p=.0001). 4) Internal consistency reliability was tested by Cronbach's ${\alpha}$. Cronbach's ${\alpha}$ was .952 for total 31 items and .950, .866 and .721 for each 3 factors related to delinquent behavior. Conclusions：The author confirmed that this scale can use for measuring delinquent behavior, and hope to make a contribution to screening test and prevention of juvenile delinquency in Korea.

This study assessed the risk of disaster by using QRE(Quick Risk Estimation - UNISDR Roll Model City of Basic Evaluation Tool) tools for three natural disasters and sixteen social disasters managed by the Seoul Metropolitan Government. The criteria for selecting 19 disaster types in Seoul are limited to disasters that occur frequently in the past and cause a lot of damage to people and property if they occur. We also considered disasters that are likely to occur in the future. According to the results of the QRE tools for disaster type in Seoul, the most dangerous type of disaster among the Seoul city disasters was "suicide accident" and "deterioration of air quality". Suicide risk is high and it is not easy to take measures against the economic and psychological problems of suicide. This corresponds to the Risk ratings(Likelihood ranking score & Severity rating) "M6". In contrast, disaster types with low risk during the disaster managed by the city of Seoul were analyzed as flooding, water leakage, and water pollution accidents. In the case of floods, there is a high likelihood of disaster such as localized heavy rains and typhoons. However, the city of Seoul has established a comprehensive plan to reduce floods and water every five years. This aspect is considered to be appropriate for disaster prevention preparedness and relatively low disaster risk was analyzed. This corresponds to the disaster Risk ratings(Likelihood ranking score & Severity rating) "VL1". Finally, the QRE tool provides the city's leaders and disaster managers with a quick reference to the risk of a disaster so that decisions can be made faster. In addition, the risk assessment using the QRE tool has helped many aspects such as systematic evaluation of resilience against the city's safety risks, basic data on future investment plans, and disaster response.

The study investigates the type of organizational culture, using the organizational culture assessment instrument(OCAI) developed by Cameron and Quinn based on the competing value model(CVM), and analyzed the gap between current and desirable organizational culture empirically. The analytic results show that while the organizational members prefer the relational organizational culture as a dominant organizational culture on the current level. Also they prefer the relational organizational culture as a desirable organizational culture on the future level. In addition, the diagnosis of organizational culture by the type of status reveals that while the public educational personnel and staff recognized the relational organizational culture as a strong culture, the local public service employee identified the hierarchical culture as a dominant culture on the current level. Those findings suggest the following implications. First, the sustainable management of organizational culture requires the suitable strategic tools. That is to say, they need to introduce and carry out practical strategies to sustain change and control for each type of organizational culture. Second, despite the fact that the balance among four types of organizational culture is needed the strategy to reinforce the dominant culture, considering the types of status and affiliation.

Various items were used as evaluation tools that identify the student's abilities accurately to confirm the completion of learning. Among them, the multiple choice item has the advantages of high objectivity and reliability in scoring, but it cannot remove the factor of guessing. In this paper, the multiple choice items are classified into two types according to the relationship between the questionnaire and the choices. One is the type used in the classical test theory with the probability of guessing 1/k for k choices and the other is the novel proposed type which introduces the concept of partial knowledge. In the proposed type, the probability of guessing when the number of knowledge i is (i+1)/k for k choices. Based on the assumptions of the previous theories about multiple choice items, we derive the guessing parameter about the proposed type. And we analyzed the effect of the guess on the correct answer in the existing type and the proposed type. This shows that the proposed type has more question guessing than the existing type.

건축디자인 초기단계에서 다이어그램은 아이디어 및 디자인 해결방안을 도출하기 위한 분석 도구로써 중요한 의미를 지닌다(Wang, 1999; Do, 1997). 이러한 다이어그램은 시각적 디자인 피드백을 가능하게 함으로써 건축디자인 실무 및 교육에서 필수적인 디자인 도구라고 할 수 있다 (Schon and Wiggins, 1992; Gross, 1996; Kurmann, 1998). 최근에 IT 기술이 건축분야에 적용됨에 따라, 건축가들의 전통적으로 고려되어 왔던 인간의 행동, 자연현상, 건축재료, 건축부재, 대지조건 외에 다양한 IT 기술과 관련된 정보를 분석하고 고려할 필요성을 가지게 되었다. 그러나 이러한 다양한 IT 기술은 건축적인 요소들과 접목되어 적용되기 때문에 건축가들은 디자인 초기단계부터 IT 기술의 접목이 가능한 디자인 도구를 필요로 하게 되었다. 즉, 이는 IT 정보와 공간정보와의 관계 및 적용을 건축가가 빠르게 이해하고 분석하고 이를 디자인에 반영할 수 있도록 도와주는 시각적 다이어그램 표출이 가능한 디자인 도구가 필요하게 되었다. 본 논문에서는 다양한 IT 기술과 공간 정보의 다양한 형태의 관계를 나타내는 3 차원 버블 다이어그램을 이용한 계략 디자인 방법을 제안하고, 이를 기반으로 3 차원 버블 다이어그램을 지원하면서 건축 디자인 초기단계에 이용 가능한 디자인 도구를 개발한다. 본 연구에서 개발된 디자인 도구는 정보의 유형에 따라 다양하게 형태를 변화시킬 수 있는 노드(node)와 연결선(edge)로 구성되고, 저장된 특정 건축정보는 다이어그램으로 생성된 디자인 대안을 평가하는데 사용된다. 일종의 DSS(Decision Support System)인 본 시스템은 디자인 초기단계에서 3 차원 디자인 아이디어를 제공할 뿐만 아니라 다양한 디자인 대안을 빠르게 생성하고 이를 실시간으로 평가함으로써 디자인 효율성을 증가시킬 것이다. 본 시스템은 유비쿼터스 기술이 적용된 신도시에 생성될 통관관제센터 디자인에 실험적으로 적용되었다.

The purpose of this study was to investigate the validity, reliability and practicality of a concept map as an assessment tool in the context of biology concept learning. Forty undergraduate students participated in concept mapping, and the maps were scored by preservice science teachers, using one of three different scoring methods, that is, concept map scoring methods developed by Burry-Stock, Novak & Gowin and McClure & Bell. Two scorers were assigned to each scoring method. As far as the validity of the assessment methods was concerned, two of the three methods were found to be very valid, while Burry-Stock's scoring method was shown little valid. As far as the internal consistency of the methods was concerned, considerably high consistencies were shown between every pair of scorers, judging from high correlation coefficients between the pair of scorers for each scoring method. It took from 1.13 minutes to 3.70 minutes to assess a map at the average. It showed that concept mapping could be used in school classrooms with the limited resources of time and people. These findings suggest that the concept mapping can be an appropriate tool for assessing biology concept understandings.

Traditional methods of detecting security vulnerabilities in source-code require a lot of time and effort. If there is good data, the issue could be solved by using the data with machine learning. Thus, this paper proposes a source-code vulnerability detection method based on machine learning. Our method employs the code2vec model that has been used to propose the names of methods, and uses as a data set, Juliet Test Suite that is a collection of common security vulnerabilities. The evaluation shows that our method has high precision of 97.3% and recall rates of 98.6%. And the result of detecting vulnerabilities in open source project shows hopeful potential. In addition, it is expected that further progress can be made through studies covering with vulnerabilities and languages not addressed here.
