The authors studied the mental health status of the 1989 freshmen of Yeungnam University using the psychotic scale of Derogatis SCL-90, Zung anxiety and depression scale and MMPI from January 1988 to February 1988. The subjects of this study were contained 3792 students(l206 female, 2586 male). 392 students(10.3%), out of all respondents were screened to fall on high score ranges. The authors performed a second test to 156(39.8% 47 female(30.1%), 109 male(69.9%)) of the high-scored in oder to clarify their mental health status and analyze various psychosocial factors; using MMPI. The MMPI results were categorized with Lachar's classification. The results were as follows. : 1. By the MMPI scores, 24 respondents(15.4%) had neurotic trends, 20(12.8%) had psychotic trends and 7(4.5%) had trends of behavior disorder. It was about 1.4% of all 3792 freshmen. 2. On the close examination of the MMPI, 8 respondents were diagnosed for affect disorder, 6 for anxiety disorder, 9 for schizophrenia and 3 for personality disorder. It was 0.7% of all freshmen. 3. On the analysis of the psychosocial factors, the schizophrenic scores were high in the case of unsatisfy infamily atmosphere, unsatisfy in marital intimacy of parents, serious in conflicts between father and I, and serious in conflicts between mother and I. 4. The hypochondriacal scores were high in the case of weak in physical condition, having hospitalization experience and physical illness.

In order to alleviate the limited resource problem and interference problem in cellular networks, the dual connectivity technology has been introduced with the cooperation of small cell base stations. In this paper, we design a new efficient and fair resource allocation scheme for the dual connectivity technology. Based on two different bargaining solutions - Generalizing Tempered Aspiration bargaining solution and Gupta and Livne bargaining solution, we develop a two-stage radio resource allocation method. At the first stage, radio resource is divided into two groups, such as real-time and non-real-time data services, by using the Generalizing Tempered Aspiration bargaining solution. At the second stage, the minimum request processing speeds for users in both groups are guaranteed by using the Gupta and Livne bargaining solution. These two-step approach can allocate the 5G radio resource sequentially while maximizing the network system performance. Finally, the performance evaluation confirms that the proposed scheme can get a better performance than other existing protocols in terms of overall system throughput, fairness, and communication failure rate according to an increase in service requests.

To establish a system for sperm swim-up separation through sucrose layer, indiscreet sperm migration should sufficiently to block but movement of sperm shouldn't inhibit. Thus, the effects of sucrose levels in sucrose layer, incubation times and types of sucrose layer on sperm separation were examined. And the results obtained were as follows; 1. Layer of 10mM sucrose inhibited sperm swim-up migration through sucrose layer. 2. Incubation for 25 minutes without sucrose layer significantly increased sperm swim-up migration. However, incubation for 10 minutes to induce swim-up through sucrose layer significantly stimulated sperm migration and maintained sperm movement. 3. There was no significant difference between Type I and Type II in barrier effect of sucrose layer. However, sucrose layer of Type II with shorter distance of barrier was efficient for sampling. To elucidate a function of follicular fluid on sperm chemotaxis using in vitro system of sucrose layer of Type II and incubation for 10 minutes, the effects of dilution, heat treatment, and protein and lipid extracts of follicular fluid on sperm swim-up separation were examined. And the results obtained were as follows; 4. Follicular fluid stimulated sperm migration and movement, and significantly-attracted capacitated-sperm at 10% level. 5. Follicular fluid heated at 55$^{\circ}C$ for 30 minutes maintained the effect of follicular fluid stimulating sperm migration and movement. 6. Follicular protein stimulated sperm movement that was reduced by filtration of the protein. 7. Follicular lipid didn't significantly stimulate sperm migration and movement. 8. Both of follicular protein and lipid reduced the effect of follicular fluid stimulating sperm migration and movement. In conclusion, sucrose layer could be used for a barrier against indiscreet sperm migration by swim-up. And follicular fluid stimulated migration and movement of sperm and attracted capacitated-sperm through sucrose layer. Especially, heat-resistant protein of follicular fluid stimulated sperm migration.

A tracheostomy tube serves as airway management for patients whose respiration is impeded due to inflammation, tumor, or traumatic events. If the patients who have tracheostomy tube, visit dental clinic for dental treatments, we should consider the underlying general condition of patients and then make treatment plans according to their state. A 22-Year old male patient, who had tracheostomy tube on his neck, came to our department for comprehensive dental treatment. Mild mental retardation was observed and he was taking anti-convulsant drugs for the prevention of epileptic seizure. Multiple advanced dental caries, hopeless teeth, and impacted third molars were also observed by clinical and radiographic examination. Due to the risk of epileptic seizure and low cooperativity to tolerate the treatment, general anesthesia was recommended by physician, and the anti-convulsant drug was administrated during procedure. In this case, we aimed to report the multidisciplinary approach for the dental treatment of patient having a tracheostomy tube.

The purpose of this study is to examine whether the national pension affects the life satisfaction of old age, using the first and third-wave data from the Korean Retirement and Income Study. The study analyzes the relationship between the national pension and life satisfaction, using several operational definitions of these two variables. This study utilizes the Difference-in-Difference(2D) models and panel data analysis. The main results are : First, the result of simple 2D shows that there is not significantly difference between the pensioner and that of non-pensioner. Second, the result of 2D regression also shows that pension is not significantly associated with life satisfaction of the old age. Lastly, the result of fixed-effect model confirms that the national pension does not have a statistically meaningful effect on the life satisfaction, controling for the unobserved characteristics of the old age. This study also conducts sensitivity analysis and discusses policy implications.

Objective : This study aimed to investigate the characteristics of the early maladaptive schemas in patients with panic disorder. Methods : Patients (n=35) included people who had met the DSM-IV-TR criteria for panic disorder. The normal control group (n=35) were those people who had no psychiatric disorder and had never experienced panic attack. The early maladaptive schemas and the severity of depression and anxiety were assessed by the Young Schema Questionnaire Short-form (YSQ-SF), the Beck Depression Inventory (BDI), and the Spielberger State-Trait Anxiety Inventory (STAI). Results : The scores on the STAI-S, STAI-T, and BDI were significantly higher in the patient group. Compared to the control group, the scores of vulnerability to harm and illness, and abandonment/instability schemas were significantly higher in the patient group. In the patient group, defectiveness/shame and subjugation schemas were found to predict BDI, dependent/incompetence, abandonment/instability schemas were found to predict STAI-S, and vulnerability to harm and illness, and abandonment/instability schemas were found to predict STAI-T. In normal controls, failure and insufficient self-control/self-discipline, failure, and emotion inhibition schemas were found to predict BDI, STAI-T, and STAI-S. Conclusions : Vulnerability to harm and illness and abandonment/instability schemas may be characteristic schema in patients with panic disorder.
