  • Oriented hand samples were collected from Gobangsan Formation and Nogam Formation in the north of Danyang and south of Yeongchun, from Bansong Group in and around Danyang, from Nampo Group in Chungnam Coalfield, from Gyeongsang Supergroup distributed from Waegwan through Daegu to Gyeongsan and from Daegu to Goryong, and from volcanic flows in Jeongog area and Jeju Island to study the paleomagnetism of southern Korea since Permian. Stepwise alternating field and thermal demagnetization experiments were carried out to determine optimum fields and temperatures. Observed mean paleomagnetic directions are as follows: $D=331.5^{\circ}$, $I=25.1^{\circ}$, $a95=12.8^{\circ}$ for Permian, $D=325.6^{\circ}$, $I=46.1^{\circ}$, $a95=11.8^{\circ}$ for Triassic, $D=313.4^{\circ}$, $I=43.1^{\circ}$, $a95=16.0^{\circ}$ for early Jurassic, $D=41.3^{\circ}$, $I=64.6^{\circ}$, $a95=4.5^{\circ}$ for early Cretaceous, $D=28.3^{\circ}$, $I=58.1^{\circ}$, $a95=2.3^{\circ}$ for late Cretaceous, $D=2.0^{\circ}$, $I=55.8^{\circ}$, $a95=6.6^{\circ}$for Quaternary. To describe the tectonic translocation of southern Korean block, northern Eurasian continental block was used as a reference frame. For each age since Permian the expected northern Eurasian field directions in terms of paleolatitude and declination were calculated. The paleolatitudes of Permian ($13.2^{\circ}N$) and early Jurassic ($25.1^{\circ}N$) obtained from the study area are quite different from those of Permian ($66.0^{\circ}N$) and early Jurassic ($68.1^{\circ}N$) which are expected for northern Eurasia. The declinations of Permian ($331.5^{\circ}$) and early Jurassic ($313.4^{\circ}$) are also quite different from those of the Permian ($56.6^{\circ}$) and the early Jurassic ($47.5^{\circ}$) expected for northern Eurasia. The Cretaceous paleolatitude is similar to the expected within error limit, but the declination for the same period is significantly different from that of the expected for the northern Eurasia. From the above evidences it is suggested that the south Korean land mass had moved from low latitude in Permian to north and sutured to northern continental block since early Jurassic. The relative rotations of early Cretaceous($27.4^{\circ}$) and late Cretaceous($10.8^{\circ}$) to northern Eurasian continent reveal that the Korean land mass might be rotated clockwise in two different times, probably in late Early Cretaceous and in Tertiary.

  • 정신과 영역의 환자를 위해 간호원의 역활을 필요로 한 이래 여러 가지 간호의 개념으로 간호원의 역할이 변화되어오고 있다. 정신과 환자의 안전만이 가장 큰 치료의 중심일 때는 병동열쇠의 위엄에 곁따라 보호관리에만 치중해 왔으며 정신의학에서 약물요법, 전기요법의 치료과정이 생기면서 간호원의 역할 변화 및 지식의 요구를 필요로 하게 되었으며, 환경과 개인의 밀접한 관계를 중시해오면서 치료적 환경속으로 환자의 인간적 치료가 강조되었을 때 의사소통과 대인관계의 인적 환경으로써 또한 간호원의 역활이 중요시 되어왔다. 이런 관점에서 치료적 환경에 대한 정확한 이해는 간호행위과정의 불완전을 제거하며 보다 활발한 정신과 환자간호에 기여하는 일 일 것이다. DR. Bartom은 병실 환경이 비생산적이고 비 치료적일때 성격의 변화는 물론 행동적 특성의 변화까지 가져올 수 있다고 말했다. 즉 무감동적이고, 무조건적 순종이 있으며 솔선하여 행하는 행위가 줄고 장래 계획에 대한 자극이 줄어들고 될대로 되어 가는 상태 그 자체에 머물러 있어 인간의 특징적 의미와 가치를 상실하게 된다는 것이다. 정신과 병실은 잠정적 체류지로 보아야 하겠고 이 체류지에서의 영향이 환자에게 보다 유익하게 끼칠려면 간호원이 지속적으로 치료적 분위기를 유지해야 할 것이다. 치료적 입장으로서의 간호의 활동 초점은 대인관계에서 환자의 의식수준과 자아관련 수준에서의 취급이 무의식 수준에서의 탐구조사보다 바람직하다. 치료적 가치로써 치료적 환경의 이론적 근거를 DR. Sullivan 은 인간의 상호관련 문제에 두고 있다. 즉 상호작용이 존재하는 환경은 어떠한 곳이든 성격에 영향이 있고 이 성격은 대인관계의 복잡성으로부터 결코 떨어질 수 없다는 얘기다. 자아구성 또한 환경의 영향을 받는데 Cumming은 병동환경과 자아구성 재동기간에 밀접성을 시사한바 있다. Visher와 O'sullivan은 정신과적 치료중에서 일상생활에서 경험되어지는 의사소통과 대인관계속에서 학습되어지는 여러 가지가 있기 때문에 매일의 활동획이 치료적 방향으로 계획되어 져야 한다고 말했다. Maxwell Jones 또한 치료적 환경의 유용한 가동은 전 직원의 기여에 있으며 이는 정신건강을 최적으로 올려 줄 것이다. 라고 말했다. 이러한 상황에서 간호원은 의미 없이 환자의 감정 욕구를 깨닫지 못하고 감정지지를 주지 못하며 정서적 긴장을 예방하지 못한 체 환자와의 관계를 유지한다면 현대간호의 개념에서 이탈되어지고 발달되어지지 못한 미숙아 현상이 유지 될 것이다. 보다 바람직한 치료적 환경 유지는 간호로써 환자에게 기여해 주는 일이다. 간호의 역활과 더불어 전문적 태도는 따뜻하고 포용성 있게 그리고 융통성 있게 대함은 물론 간호인 자신의 "자기이용"을 깊이 그리고 치료적으로 이용할 것을 깨달아야 할 것이다. 즉 정신과 병실에서의 간호원 존재 자제가 환자에게 미치는 영향도 고려해야 한다는 것이다. 덧붙여 환자를 위한 일주일 병동 행사표를 Model로 제시하였고 그 안에서의 간호원의 역활을 약술하였다.

  • This study aims to analyze the correlation of creative personality, environment, process, and product as related to scientific creativity for different levels of elementary school students. We evaluated 105 fifth graders' responses to two tests: i) the scientific creativity test for creative process and product and ii) the self-report test for creative personality and environment. In the self-report test, creative personality comprises cognitive and affective personality, and creative environment constitutes home and school environments. To attain a deeper understanding of phenomena that cannot be explained by a quantitative analysis, interviews were conducted with four students who had the highest scores in creative product and four students who had the lowest scores in creative product while having higher-than-average scores in creative process. First, correlation of creative personality and environment were not significant. Second, in the interviews, students who had the highest scores in scientific creativity had common characteristics, namely, the ability to endure current difficulties to achieve future success and the propensity to listen to other people's ideas critically. Third, students who had the highest scores in creativity hailed from families that respected their opinions, whereas students with the lowest scores belonged to families that disregarded or neglected their opinions. Finally, this study specifies the criteria that should be considered for affective and environmental aspects of scientific creativity education.

  • Purpose : Renal blood oxygen level-dependent (BOLD) MRI has been used in the evaluation of renal oxygenation. We tried to provide the normal $R2^*$ value of the human kidney with 3.0 T, and evaluated the differences in $R2^*$ values according to gender and location. Materials and Methods: Twenty-four healthy volunteers underwent BOLD MRI at 3.0 T. Multi gradient echo-echo planar imaging sequence with seventeen echoes was used. After generation of the $T2^*$ map, the $R2^*$ was calculated. The statistical differences in $R2^*$ values between the cortex and medulla, males and females, and the right and left kidney were analyzed. The regional differences of $R2^*$ within the both kidneys were evaluated respectively. Results: BOLD MRI was successful in all participants. No gross artifact interfered with $R2^*$ measurement. The mean $R2^*$ at 3.0 T was $17.1{\pm}2.60s^{-1}$ in the cortex and $27.7{\pm}4.83s^{-1}$ in the medulla (p < 0.001). The $R2^*$ value in the medulla was significantly higher in the male than female volunteers (p = 0.025). There were no statistical differences of $R2^*$ according to the side and location in the kidney (p = 0.197). Conclusion: Renal BOLD MRI can be efficiently performed with 3.0 T MRI. Renal medullary hypoxia is present in normal volunteers. Our results may be used as reference values in the evaluation of pathologic conditions using BOLD MRI.

  • In this study, which is based on the findings of the preceding studies, the researchers determined social support and Career Decision Self-efficacy as the key influencing variables for the successful Career Preparation Activities, to analyze the relationship between Career Preparation Activities and these variables, while identifying the mediating effect of Career Decision Self-efficacy in the relationship between social support and Career Preparation Activities. In addition, there is an objective to provide effective career counseling materials. For this study, a total of 174 North Korean adolescent defectors, who were in their middle and high schools, were interviewed and the resultant data were analyzed the data based on the questionnaire data of 204 copies from March 12 to 19, 2019. For the analysis of the data, SPSS and AMOS statistical suites were used to verify the hypothesis. The result of the analysis showed that, first, in the relationship between the social support, Career Decision Self-efficacy, and Career Preparation Activities of the North Korean adolescent defectors social support, Career Decision Self-efficacy, and Career Preparation Activities were all positively related. Especially, Career Decision Self-efficacy has been identified as the variable that is highly related to Career Preparation Activities. Second, rather than social support(${\beta}=.107$), Career Decision Self-efficacy(${\beta}=.388$) turned out to have more profound direct influence on Career Preparation Activities. Third, social support did not influence Career Preparation Activities directly(${\beta}=.107$, p>.05) but completely intermediated Career Decision Self-efficacy to influence Career Preparation Activities(Indirect effect=.307, p<.05, Z-value=2.924, p<.01). The findings of this study show that, in order to enhance the Career Preparation Activities of the North Korean adolescent defectors, it is necessary to examine how they perceive the emotional, informational, material, and evaluative supports from the surrounding environment are perceived and identify the abilities, values, and career desires of themselves through a behavioral planning that can establish a professional and value system in accordance with them.

  • As a result of this study only a few Korean firms have a certain management methods designed to predict the possibility of risk occurrence and establishment of systematic countermeasure. Besides, the Korean firms do not have enough data on the risk of Chinese Market. The risk management department inside the firm does not function efficiently, and when it comes to investigation of risk, it heavily depends on that of local branches. Accordingly, in order to accurately recognize and manage, the firms need to not only specialize risk management department but also outsource by using a consulting firm.

  • Individual characteristics and entrepreneurship are important factors to determine entrepreneurial intentions. Despite this, little attention has been given to external factors, which effects to venture start-up decision. This study examines the relationship between individual characteristics and entrepreneurship by moderating effect of Hofstede's cultures dimensions theory. For this, 244 copies of the questionnaire were empirically analyzed. According to the results of analysis, internal locus of control, self-efficacy were found to have positive effects on autonomy, innovativeness, pro-activeness. In addition, uncertainty avoidance of Hofstede's cultures dimensions theory were found the moderating effects on entrepreneurship and entrepreneurial intentions. Therefore, this study suggests theoretical and practical implications, as below, according to the results. Firstly, pro-activeness take a important part on venture start-up. Thus, venture start-up institution and venture managers need to develop "venture education curriculum" that fostering the pro-activeness mind of entrepreneur. Secondly, In order to anticipate entrepreneurial intentions more precisely, analyzing the interaction between environmental variables and individual variables is desirable. Lastly, in the future study of entrepreneurship, the comprehensive analysis of correlation between the factors that including three factors of entrepreneurship is need to be conducted and more effective way of readdressing the entrepreneurship is necessary.

  • This study was carried out to define the characteristics of the identified ground-dwelling invertebrate communities at Nari basin and Tonggumi area in Ulleungdo Island, designated as a nationally important agricultural heritage. The habitat types were divided into the following categories: crop land, forest, and ecotone, and the soil-dwelling invertebrates were collected according to habitat type. The ground-dwelling invertebrates were collected using a pitfall trap, and a self-organizing map (SOM) was applied to the invertebrates dataset to define the characteristics in invertebrates distribution. The SOM clearly classified the relevant information into four clusters, and extracted ecological information from the invertebrates dataset. The cluster II was composed of invertebrate communities which are collected in the Tonggumi area. The Tonggumi area is where mountainous areas were developed for agricultural purposes, which has geographical features commonly observed in Ulleungdo Island. It is noted that the cluster II has different characteristics as compared other clusters. The results of this study are expected to be used for the preservation of agricultural environment and maintenance of biodiversity by providing basic data, on the biotope of Ulleungdo Island designated as a nationally important agricultural heritage and information on the characteristics of the applicable ground-dwelling invertebrate communities.

  • This paper proposes the performance evaluation test of attitude heading reference system (AHRS) suitable for small high speed autonomous underwater vehicle(AUV). Although IMU can provides the detail attitude information, it is sometime not suitable for small AUV with short operation time in view of price and the electrical power consumption. One of alternative for tactical grade IMU is the AHRS based micro-machined electro mechanical system(MEMS) which can overcome many problems that have inhibited the adoption of inertial system for small AUV such as cost and power consumption. A cost effective and small size AHRS which incorporates measurements from 3-axis MEMS gyroscopes, accelerometers, and 3-axis magnetometers has been developed to provide a complete attitude solution for AUV and the attitude calculation algorithm is derived based the coordinate transform equation and Kalman filter. The developed AHRS was validated through various performance tests as like the magnetometer calibration, operating experiments using land mobile vehicle and flight motion simulator (FMS). The test of magnetometer calibration shows the developed MEMS AHRS is robust to the external magent field change and the test with land vehicle proves the leveling error of developed MEMS AHRS is below $0.5^{\circ}/hr$. The results of FMS test shows the fact that AHRS provides the measurement with $0.5^{\circ}/hr$ error during 5 minutes operation time. These results of performance evaluation tests showed that the developed AHRS provides attitude information which error of roll and pitch are below $1^{\circ}$ and the error of yaw is below $5^{\circ}$ and satisfies the required specification. It is expected that developed AHRS can provide the precise attitude measurement under sea trial with real AUV.
