The purpose of this study is to analyze and compare brain activation that appears in the self-regulation process of biology major and non-major college students in life science learning. The self-regulation task implemented a life science learning situation with the concept of biological classification. The brain activation of college students was measured and analyzed by fNIRS. In the assimilation process, bilateral FP and left DLPFC show significant activation, and the two groups show a difference in the left OFC activation related to motivation and reward. In the conflict process, the left DLPFC shows significantly lower activation in common, and the two groups show a difference in activation between BA 46, which is related to recent memory, and BA 47, which is related to long-term memory. In the accommodation process, a significantly high activation was found in right DLPFC in common, and the two groups show a difference in activation between right DLPFC and right FP. These areas are in the right frontal lobe area and are related to the understanding of life science knowledge. As a result of this study, it can be seen that the brain activation patterns of biology major and non-major college students are different in the self-regulation process. In addition, we will propose additional neurological studies on self-regulation and present systems and learning strategies that can be constructed in school settings.

This paper is to examine the issues of the right of portrait and to suppose practical guideline for performing arts archives. The right of portrait protects external looks of the human beings based on the constitutional human dignity, privacy of a secret and freedom. But sometimes these rights are limited in case of the right to know of the public shall have precedence to the interests of the privacy of individuals. It is hard to regard Performing Arts as a private life in two respects: first, Performing Arts is just one of societal expressions, two, performers are conducting a given role as a performing character. Producing database with the photos and videos under the reasonable agreement from the performers and making it available as a service can be disclaimers of the right of portrait. It is hard to be acknowledged, however, as disclaimers in case of being undermined sameness in the course of using the portraits of the performers.

A pulsed tracer gas technique is applied to measure distributions of local mean age and residual life time of air in a half-scale experimental chamber. The room airflow patterns are flow-visualized by a Helium bubble generator for three different exhaust locations. A supply slot is located at the top of a right wall, and an exhaust slot is either at bottom-left(Case 1), bottom-right(Case 2), or top-left(Case 3) location. Results show that the distribution of LMA and LMR are different from each other, but both of them are closely related to the airflow pattern in the space. Results on overall room ventilation effectiveness are provided depending upon ventilation airflow rates for three different supply-exhaust configurations.

This paper is to introduce the main modeling assumptions and data structures associated with right-censored data to describe the successful methodological ideas for analyzing such a field-failure-data when components operating in different environments. The Kaplan - Meier method is the most popular method used for survival analysis. Together with the log-rank test, it may provide us with an opportunity to estimate survival probabilities and to compare survival between groups. An important advantage of the Kaplan - Meier curve is that the method can take into account some types of censored data, particularly right-censoring. The above non-parametric method was used to verify the equality of parts life used in different environments. After that, we performed the life distribution analysis using the parametric method. We simulated data from three distributions: exponential, normal, and Weibull. This allowed us to compare the results of the estimates to the known true values and to quantify the reliability indices. Here we used the Akaike information criterion to find a suitable life time distribution. If the Akaike information criterion is the smallest, the best model of failure data is presented. In this paper, no-nparametrics and parametrics methods are analyzed using R program which is a popular statistical program.

Capital punishment is a system which is not finished simply as one of interim penalty but does away with one person's existence eternally. It is not only opposite to the existential humanism but also contrary to social welfare's goal like social integration. Therefore, this study tries to find out the issues related to capital punishment and further tries to draw out the rightness of capital punishment abolition by critically reviewing the capital punishment system on the basis of the value and philosophy of correctional welfare. In brief, capital punishment is possible only when we negate the inviolable fundamental right which is called life right, and deny the human life existence which surpasses space and time. As long as we can not deny the macroscopic viewpoint to search out the basis of human behavior in the social system which is called culture and society, capital punishment system is contrary to the philosophy of welfare that total society is responsible for guiding members of society to pursue self realization on the basis of value like social solidarity and human dignity. Also, it is against the objective of correctional welfare to head toward special prevention by positive correction and rehabilitation. Capital punishment system ought to be abolished properly.

The clinical findings with cardioangiography and successful surgical treatment of a 10 year old girl with double-outlet right ventricle is reported at The Dept. of Thoracic and Cardiovascular Surgery, Korea University Hospital, College of Medicine. The patient has been suffered from intermittent cyanosis, palpitation, and exertional dyspnea since 1 year after NFSD, and a holosystolic ejection murmur of grade 4 at the left 3rd intercostal space with mild cyanosis of the lips was the only physical findings at the time of this admission. Cardiac catheterization revealed ventricular septal defect with left to right shunt of 43% and right to left shunt of 10.2%. On cardioangiography from the left ventricle revealed all of the left ventricular outflow shunted into the right ventricle through the large ventricular septal defect, and the aorta originated from the infundibular chamber of the right ventricle with left, anterior sided pulmonary artery. The atria, viscera, and ventricles were normally located, and right ventricular out-flow was narrowed with infundibular hypertrophy and pulmonary valvular stenosis. Surgical correction was accomplished by closure of the ventricular septal defect in such a way that left ventricular outflow was routed via a Teflon felt prosthetic tunnel to the aorta, and pulmonary valvulotomy with infundibulectomy Was done to pass Hegar`s dilator No. 15 for reconstruction of the right ventricular outflow tract. The patient tolerated complete repair and has continued to improve over a period of three months after operation with normal school life. Details of the disease and method of repair are presented with related references.

Purpose: This study aims to determine the bioethical subjectivity of nursing students with experience volunteering in elderly care facilities, and the characteristics that comprise the types thereof. Methods: Q methodology, which analyzes the subjectivity of each type, was used. The 37 selected Q statements from 32 participants were classified into the shape of a normal distribution using a 9-point scale. The collected data were analyzed using the PC-QUANL program. Results: The survey revealed that the bioethical subjectivity of nursing students with experience volunteering in elderly care facilities can be divided into three types: a rational dignity emphasis, an autonomous right to life belief, and conflict avoidance. All three attitudes regard human beings as possessing dignity, and life and death as elements to be experienced as aspects of human life. Bioethical values are critical to treatment and care; however, it is sometimes also held that humans have the right to commit suicide. Conclusion: This study enhanced our awareness of nursing students' bioethics. The findings can be used as a basis for the design of differentiated bioethics education according to each type of bioethical subjectivity. This calls for diverse research on bioethics and the implementation of effective bioethics education.

A study on establishment of normal range of cardiothoracic ratio calculated from photofluorography film of chest by age and sex in a total of the 6,598 insureds was undertaken. The results were as follows: 1. In male group, the frequency distribution of cardiothoracic ratio was skewed weakly to the right in second decade, symmetrical in third and fourth decade, and was skewed weakly to the left in fifth and sixth decade; in female group, it was skewed weakly to the left in second, third and fourth decade, and was skewed weakly to the right in fifth and sixth decade. 2. On assumption that normal range of cardiothoracic ratio should comprise about 85% of all cardiothoracic ratios in each age group of both sexes, the sites of deviation from mean value of cardiothoracic ratio corresponding to maximum and minimum cardiothoracic ratio in the range of about 85% above mentioned were detected by statistical method on the frequency distribution of log tranformed cardiothoracic ratio, and $M{\pm}1.3$ sindicating normal range of cardiothoracic ratio was determined. In male group, normal range of cardiothoracic ratio determined by statistical method is 35-45%, 40-50%, 40-50%, 40-50% and 40-50% succesively in order from second to sixth decade; in female group, 40-50%, 40-50%, 40-50%, 45-55% and 45-55%.

Purpose : We aimed to evaluate the impact of a exercise with kinect-based mixed reality device (KMR) on physical function, upper extremity disability, fatigue, and quality of life in breast cancer survivors. We hypothesized that this exercise program would improve physical function, physical activity, fatigue, and quality of life. Methods : Thirty-nine breast cancer survivors were randomized to either the KMR exercise group (KE) or the home stretch group (HS). The KE participated in 8 weeks of exercise, exercising 3 times per week, while the HS performed 8 weeks of stretching exercises, also 3 times per week. Before and after the intervention period, participants underwent assessments of physical function, including body composition, chester step test (CST), and hand grip strength (HGS). Additionally, participants completed questionnaires including the international physical activity questionnaire (IPAQ), disabilities of the arm, shoulder and hand (DASH) questionnaire, and functional assessment of cancer therapy-breast (FACT-B) questionnaire to measure their physical activity levels, upper extremity disability, and quality of life, respectively. Results : Overall, significant improvements were observed in several shoulder movements, body weight, and physical activity, with no significant interaction effects between groups and time. Furthermore, there was a significant group by time interaction for body weight, left flexion, right flexion, right abduction, and left adduction, as well as for upper extremity disability (K-DASH) and quality of life (FACT-B). Conclusion : In conclusion, the KMR exercise program was found to be effective at improving physical function, upper extremity disability, quality of life, and overall well-being in breast cancer survivors. The significant improvements observed in multiple measures and the significant group by time interactions for various outcomes highlight the potential benefits of this KMR exercise program in promoting a better quality of life for breast cancer survivors.

Reexpansion pulmonary edema[ RPE ] with hypoxemia and hypotension is a very rare complication of the treatment of lung collapse secondary to pneumothorax and pleural effusion. We experienced two cases of RPE. One is a 29 year old male with complete right pneumothorax and the other is a 20 year old female with massive right pleural effusion. Life threatening pulmonary edema was developed soon after insertion of chest tube in both. Fortunately, RPE was detected early and intensive treatment was performed. They were discharged without complication. Although RPE with hypoxemia and hypotension is rare , it is very serious and occasionally life-threatening. So, chest surgeon treating lung collapse must be aware of the possibility of RPE and make an effort to prevent the occurence of this condition.
