Together with the development of space science outer space law has become one of the most rapidly developing branches of international law. This reflects a general realization that these new activities must be subject to reasonable legal regulation if they are to serve the peaceful purposes of mankind without undue confusion and disorder. The exploration and use of outer space introduces many novel opportunities and dilemmas, and inspired insights are needed in the development of this new resource. In particular, the settlement of space law disputes is a relatively new discussion in international law. However, the significance of the settlement of space law disputes was acknowledged in various colloquia organized by legal academicians and practitioners around the world. Analysis of the dispute settlement provisions in space agreements plainly reveals the degree to which States persist to be mistrustful of any impingement to their sovereignty. They are reluctant to submit disputes to adjudication and binding arbitration, particularly when these provisions are negotiated between States which have dissimilar political, economic and social interests and demography. However, there is a slow but clear shift in this attitude as States realize the contemporary political, economic and technical pressures necessitating the lifting of the veil of State sovereignty. The development of an effective mechanism for the settlement of disputes arising in relation to the development of the exploration and exploitation of outer space has been the subject of global study by highly qualified publicists and international institutions. The 1972 Liability Convention is the space treaty with the most elaborate provisions for dispute settlement. However, it fails to ensure binding decisions. In this point, the 1998 Taipei Final Draft Convention may be a useful instrument for further consideration on whether an independent sectorialized dispute settlement mechanism should be established. Considering these circumstances it seemed essential to take legislative action to implement a system as comprehensive as the relevant legal framework are in the Law of the Sea and International Criminal Law mechanisms for dispute settlement and conflict avoidance from outer space activities.

Residential Environment Improvement Project (REIP) which has started in 1989 and continued with 3rd government-supporting project in 2013 has lots of policy changes and related studies. However, the related researches have focused on residents resettlement into the project site, this paper is more interested in the residents stability than residents resettlement. So, this paper analyzes the changes of residents stability on the site of REIPs (with 3 groups of dwellers, removers and newcomers). We survey about understanding of those projects, each interior physical housing characters, housing cost, outside settlement characters. On the base of case analysis, we can conclude as follows: firstly, the residents are more young, higher educated, and higher income but not alter to household, barrier, occupation. Secondly, REIPs have some positive influences on physical conditions of housing and outside characters but negative impacts on housing cost. In case of newcomers, there are no changes of housing size and room numbers but higher housing cost, better outside settlement conditions.

The purpose of this study was to investigate the effects of teaching based on analysis of a hierarchy of the concepts associated with astronomical observation as well as each learner's status of knowledge through analytical methods of the knowledge state. A test instrument was developed to measure high school students' concepts associated with astronomical observation before instruction. The learners' psychological hierarchy associated with astronomical observation that the participants possessed showed the order of 'motion of the earth${\rightarrow}$coordinate system${\rightarrow}$astronomical observation (mechanism of the telescope${\rightarrow}$installation of the telescope${\rightarrow}$observation through the telescope)', and so was the hierarchy of teaching (70.6%). The learners' knowledge state that is supposed to be similar each other in the ability of observing celestial bodies was different even through they scored the same on the concept test. There were cases with the knowledge state well-structured and not well-structured, which suggests that differentiated instruction with appropriate teaching-learning prescriptions be prepared. An analysis of the knowledge state can play the role of both preparing individualized learning prescriptions and formative evaluation. In the unit dealing with astronomical observation of Earth ScienceI, teaching according to the psychological hierarchy of learners rather than the order in which the textbook syllabi were presented scored significantly higher (p<0.05) on the level of concept achievements. This result suggests that the teacher can help students achieve more efficient in learning by analyzing the learner's knowledge state and reordering the syllabi of the textbook in teaching the concepts associated with astronomical observation.

The road network system of major domestic urban areas such as city of Seoul was rapidly developed and regionally expanded. In addition, many kinds of life-lines such as electrical cables, telephone cables, water&sewerage lines, heat&cold conduits and gas lines were needed in order for urban residents to live comfortably. Therefore, most of the life-lines were individually buried in underground and individually managed. The utility tunnel is defined as the urban planning facilities for commonly installing life-lines in the National Land Planning Act. Expectation effectiveness of urban utility tunnels is reducing repeated excavation of roads, improvement of urban landscape; road pavement durability; driving performance and traffic flow. It can also be expected that ensuring disaster safety for earthquakes and sinkholes, smart-grind and electric vehicle supply, rapid response to changes in future living environment and etc. Therefore, necessity of urban utility tunnels has recently increased. However, all of the constructed utility tunnels are cut-and-cover tunnels domestically, which is included in development of new-town areas. Since urban areas can not accommodate all buried life-lines, it is necessary to study the feasibility assessment system for utility tunnel by urban patterns and capacity optimization for urban utility tunnels. In this study, we break away from the new-town utility tunnels and suggest a quantitative assessment model based on the evaluation index for urban areas. In addition, we also develop a program that can implement a quantitative evaluation system by subdividing the feasibility assessment system of urban patterns. Ultimately, this study can contribute to be activated the urban utility tunnel.

Biometric authentication is rising technology for the security market of the next generation. But most of biometric systems are developed using only one of various biological features. Recently, there is a vigorous research for the standardization of various biometric systems. In this paper, we propose a web-based authentication system using three other verifiers based on functional, parametric, and structural approaches for one biometrics of handwritten signature, which is conformable to a specification of BioAPI introduced by BioAPI Consortium for a standardization of biometric technology. This system is developed with a client-server structure, and clients and servers consist of three layers according to the BioAPI structure. The proposed neb-based multiple authentication system of one biometrics can be used to highly increase confidence degree of authentication without additional several biological measurements, although rejection rate is a little increased. That is, the false accept rate(FAR) decreases on the scale of about 1:40,000, although false reject rate(FRR) increases about 2.7 times in the case of combining above three signature verifiers. So the proposed approach can be used as an effective identification method on the internet of an open network. Also, it can be easily extended to a security system using multimodal biometrics.

Purpose : This study was designed to investigate normal domestic values for the diameter of the left main coronary artery (LCA), the left anterior descending coronary artery (LAD) and the right coronary artery (RCA). These data are necessary to define dilatation of coronary arteries in Kawasaki disease cases. Methods : Study subjects were 43 normal healthy children whose ages ranged from 3 months to 6 years. They children visited Konkuk University hospital for echocardiograph examination between March 2005 and November 2007. Measurements of coronary arterial diameters at each branch were done by off-line analyses of recorded images. Simple regression analysis of each the measurements were performed using the body size (body surface area, etc.) as the independent variable. Results : Body surface area was significantly related to the diameters of LCA ($r^2=0.20$, P=0.0038), of LAD ($r^2=0.41$, P<0.0001), and of RCA ($r^2=0.30$, P=0.0002). In the regression model, the estimates of the y-intercept were 1.703, 1.058, and 1.007; the estimates of the regression coefficient were 0.971, 1.175, and 1.177; and the estimates of the standard deviation were 0.315, 0.221, and 0.282 with respect to the three coronary arteries. Conclusion : A the linear regression model of the diameters of three coronary arteries adjusted for body surface area was produced. With these results, the Z-score calculation of the diameter of three coronary arteries, based on normal domestic data, will be possible.

Art. 2 Abs. 1 GG sch${\ddot{u}}$tzt umfassend die allgemeine Handlungsfreiheit. Daher bed${\ddot{u}}$rfen private Handlungen grunds${\ddot{a}}$tzlich keiner gesetzlichen Erm${\ddot{a}}$chtigungsgrundlage. Dies gilt selbstverst${\ddot{a}}$ndlich auch fur die Unternehmen der Bewachungsbranche. Allerdings ist es bei der Aus${\ddot{u}}$bung der Bewachungsaufgabe typisch, mit Strafe oder zumindest Schadensersatzpflicht sanktionierte Tatbest${\ddot{a}}$nde zum Nachteil Dritter zu verwirklichen. F${\ddot{u}}$r solche F${\ddot{a}}$lle stehen den Bewachungspersonen m${\ddot{o}}$glicherweise Rechtfertigungsgr${\ddot{u}}$nde zur Seite. Dadurch wird ein ansonsten rechtswidriges Handeln rechtm${\ddot{a}}$${\ss}$ig und so wird im Ergebnis eine Strafbarkeit (wie auch eine Schadensersatzpflicht) ausgeschlossen. Dabei wird klargestellt, dass dem Sicherheitsgewerbe au${\ss}$er in den F${\ddot{a}}$llen der gesetzlichen ${\ddot{U}}$bertragung der hoheitlichen Befugnisse nur die vom Auftraggeber vertraglich ${\ddot{u}}$bertragenen privatrechtlichen Befugnisse sowie die Jedermannsrechte zustehen Au${\ss}$erdem soll im Rahmen der Privatisierung der Gefahrenabwehraufgaben auf solche spezialgesetzlichen Regelungen hingewiesen werden, bei denen Bewachungspersonen mit der hoheitlichen Wahrnehmung bestimmter Sicherheitsaufgaben betraut, d.h. dazu befugt sind, Sicherheitsaufgaben in den Handlungsformen des ${\ddot{O}}$ffentlichen Rechts 면켜${\ddot{u}}$ben. In der koeranischen Literatur ist die Handlungsgrundlage des Bewachungspersonals bis jetzt kaum n${\ddot{a}}$her untersucht. Im allgemeinen werden strafrechtliche Rechtferigungsgr${\ddot{u}}$nde, z.B. Notwehr, Notstand und Selbsthilfe, als dabei anwendbare Normen anerkannt. In dieser Arbeit wird festgestellt, dass die privaten Sicherheitsdienstleister in beiden L${\ddot{a}}$ndern durch die Gewerbegenehmigung au${\ss}$er in den F${\ddot{a}}$llen der Beleihung keine hoheitlichen Befugnisse erhalten. Als Handlungsgrundlage kommen nur die allgemeinen Not- und Jedermannsrechte im Rahmen von Straf-Strafprozess- bzw. Zivilrecht in Betracht.

Objectives: This study aimed to evaluate the clinical efficacy of individual cognitive behavioral therapy (CBT) for Patients with Primary or Secondary Insomnia. Methods: Participants were recruited from a primary care sleep clinic from January 2008 to June 2009. The study sample included 64 outpatients with primary insomnia (n=30) and secondary insomnia (n=34) according to the criteria of DSM-IV. Participants completed sleep diaries, Dysfunctional Beliefs and Attitudes about Sleep Scale-16 (DBAS), State-Trait Anxiety Inventory (STAI) before CBT and shortly after completion of CBT. CBT was provided in 7 weekly, 40-50-minute individual therapy sessions. Results: Both groups of patients with primary and secondary insomnia showed significant improvement in the DBAS and sleep parameters including sleep onset latency, total sleep time, and sleep efficiency. Repeated-measures ANOVA of the DBAS and sleep parameters showed no significant group-by-time interactions between patients with primary and secondary insomnia, suggesting the efficacy of CBT for patients with secondary insomnia was equivalent to that of CBT for patients with primary insomnia. Conclusion: This study suggests that CBT is effective for the management of primary and secondary insomnia in a primary care setting.

In this study, we investigated the characteristics of the pedagogical content knowledge (PCK) components and their integrations in the processes of developing performance assessment tasks of pre-service chemistry teachers who participated in the constructive performance assessment workshop. Eight pre-service teachers participated in this study. After three weeks of the constructivist performance assessment workshop, they developed their own performance assessment tasks. The think-aloud method was used to investigate their developing processes. Their activities were recorded and videotaped, and semi-structured interviews were also conducted. The analysis of the results revealed that the PCK component considered in the planning step showed similar frequencies for assessment, instructional strategies, students, and subject matter components. In the embodying step, assessment component was most frequent. In the discussion step, the frequencies for assessment, instructional strategies, and students components were similar. However, curriculum component and the subcomponent of science process skill were rarely used. The integrations among the PCK components were found to be centered on the instructional strategies component in the planning step and the students component in the embodying and discussion step. However, curriculum and subject matter components were rarely integrated with other PCK components. On the basis of the results, educational implications are discussed.
