  • In this paper, the wave run-up height and depression depth around air-water interface-piercing circular cylinder have been numerically studied. The Reynolds Averaged Navier-Stokes equations (RANS) and continuity equations are solved with Reynolds Stress model (RSM) and volume of fluid (VOF) method as turbulence model and free surface modeling, respectively. A commercial Computational Fluid Dynamics (CFD) software "Star-CCM+" has been used for the current simulations. Various Froude numbers ranged from 0.2 to 1.6 are used to investigate the change of air-water interface structures around the cylinder and experimental data and theoretical values by Bernoulli are compared. The present results showed a good agreement with other studies. Kelvin waves behind the cylinder were generated and its wave lengths are longer as Froude numbers increase and they have good agreement with theoretical values. And its angles are smaller with the increase of Froude numbers.

  • The Purpose of this study was to build a substantive theory about the experience of postpartum depression. The qualitative research method used was rounded theory. The interviewees were eight others who had experienced postpartum depression. The data were collected through in-depth interviews with audiotape recording done by the investigator over a period of twelve months. he data were analyzed simultaneously by a constant comparative method in which new data were continuously coded into categories and properties according to Strauss and Corbin's methodology. Analysis the grounded data resulted in 28 concepts being identified. Eight categories emerged from the analysis. The categories were regret, loss of freedom, isolation of oneself, heartache, loss, emotional upset, avoidance, recovery. These substantive categories are consistent with precious research results. Causal conditions included : regret, loss of freedom. Phenomena : heartache, loss, emotional upset. Context : isolation oneself. Intervention condition : avoidance. Action/interaction strategies : desire for recovery. Consequences : recovery. These categories were synthesized into the core concept-The process of filling the empty loss of self. The process of the experienced postpartum depression was ① change after delivery, ② searching for a reason for depression, ③ effort to recover from postpartum depression, ④ recovery from postpartum depression and return to previous life. The process of recovery from postpartum depression was proceeded by ① support from others, especially husband, ② resolution of stressful life events, ③ reconstructing of life goals and resolution strategies, ④ acceptance of depression and seeking psychiatric treatment. Seven hypotheses were derived from the analysis. ① Mothers who experienced stressful life event and economic problem are more depressive. ② Mothers who have conflict with parents are more depressive. ③ The more somatic symptoms, the more depression. ④ Social support facilitates recovery from postpartum depression. ⑤ Mothers who have lower self-esteem are more depressive. ⑥ Mother's role overload disturbs recovery from postpartum depression. ⑦ Ideal maternal identity facilitates recovery from postpartum depression. Through this substantive theory, nurses can understand the importance of postpartum depression management.

  • 40대 이후 급증하는 중년여성의 우울증은 다양한 치료방법에도 불구하고 좀처럼 감소하지 않고 있다. 이러한 현상이 자기상실에서 오는 전체성의 몰인식에서 기인한다는 전제하에, 보다 근원적인 치료방법을 위한 질적 연구가 필요하다. 이에 본 연구는 2016년 9월부터 2018년 11월까지 우울증을 호소하는 3명의 기독교인 중년여성을 연구 참여자로 선정, 10~15회기 심층상담과 인터뷰를 실시하여 261개의 의미단위와 11개의 하위구성요소를 도출하였으며 도출한 의미단위를 2개의 주제군인 우울증 경험과 개성화과정의 현상으로 나누어 구조화하였다. 심층상담 결과를 바탕으로 우울증 경험과 개성화과정의 현상으로 구조화한 결론은 다음과 같다. 첫째, 우울증의 경험은 신체적, 인지적, 정서적, 행동적, 사회적, 영적인 면에서 고통스러운 증상으로 나타나는데 이는 삶의 의미를 찾으려는 의욕으로 변환되고 새로운 길을 모색하는 창조적 질서를 위한 과정으로 연결된다. 둘째, 중년여성의 개성화과정 현상은 페르소나, 그림자·콤플렉스, 아니무스와의 직면에서 또 다른 고통을 불러오지만, 동시에 이를 극복하기 위한 겸손과 용기의 태도 또한 가져온다. 셋째, 중년여성의 개성화과정에서 자기실현의 현상은 카타르시스 후 자기성찰을 통해 문제를 인식하고 수용하는 것으로부터 시작되고 점차 인격과 관계의 변화, 전반적인 삶에서의 변화, 종교적인 영역에서의 변화, 인지적·정서적·행동적인 영역에서의 긍정적 변화 등이 나타났다. 결론적으로 본 연구를 통해서 우울증을 경험한 중년여성이 고통의 본질적인 의미를 깨닫고 개성화과정을 통해 근원적으로 치료 받을 수 있는 계기를 마련하고, 일반 중년여성들에게도 예방적 차원의 방법을 제시하였다는 데 의의가 있다.

  • The HI features associated with HII regions and radio sources in the galactic-plane are searched in the Maryland-Green Bank Galactic 21-cm Line Survey. Among the twenty-eight such objects, twenty-five show HI depression features, two no feature, and an emission feature with excess HI brightness temperature. Most of these feature are surrounded by strong HI emissions. The depth of the HI depression is proportional to the radio continuum brightness temperature. The angular dimensions of the HI feature and radio source are comparable. The small HI depressions shown at the positions of HII region located in the outer solar circle are considered to be HI self-absorption features of very cold HI gas.

  • Purpose: Accessory tragus is a fairly common congenital malformation and usually located at pretragal area. Surgical removal is a common treatment of accessory tragus irrespective of location and morphology. Most accessory tragi do not have depression site around them, but some do. So in those cases, simple surgical excision was not enough to promote the aesthetic facial appearance. For depression site remodeling, the excess amount of skin and cartilage need to be remained partially instead of total excision. This method can achieve the symmetric contour of pretragal area. The authors excised the epidermis and cartilaginous tissue totally and remained the dermis for reconstruction of the depression site around accessory tragus. The depression site is filled with dermal turnover flap. The purpose of this report is to present new idea to promote cosmetic result in treatment of accessory tragus containing the depression site. Methods: Two patients had a pair of accessory tragi at pretragal area. One was a common featured accessory tragus, but the other was different. Depression site was found around accessory tragus. After epidermis and cartilaginous tissue were removed from it, dermis component was used as turnover flap for reconstruction of depression site. Results: After accessory tragus was removed and depression site was reconstructed, facial contour and cosmetic result was achieved. Complication such as flap necrosis and wound dehiscence was not observed. Conclusion: The accessory tragus has variant morphology and degree of invasive depth. And some has a depression site around them. In those cases, simple surgical removal results in morphological distorsion and do not promote facial symmetry. The authors suggest dermal turnover flap as reconstruction method of the depression site. This method improves both surgical outcome and cosmetic result.

  • The purpose of this research was to develop and evaluate a preventive mental health program for the depression among the elderly in community. Based on the review of literature, intervention program for preventing depression among the elderly was developed. In particular, the program focuses on enhancing the sense of control which is from social cognitive theory. The preventive mental health program consists of two parts: Tan-Hak and Social intervention program. Tan-Hak was oriented to cognitive change and activities, while social intervention program dealt with some social skills for relationship, stress management, motivation of social activities (volunteer activities), positive future designing, etc. For the evaluation of this program, we employed depression scale and medical measurement such as hormone test before and after the program, and in-depth interview of subjects. Overall, this program was successful in some points. First, through the pre and post test, this program has positive effect on strengthening the sense of control, and consequently, lowering depression level. Secondly, 18 people started this program called "smile class" at first time, and none of them turned out until the end of the program. This implies that the program was interesting to the elderly.
