        사회활동과 우울의 관계에 대한 일 연구

        김영범(KIM Young Bum) 지역사회학회 2015 지역사회학 Vol.16 No.1

        본 연구의 목적은 사회활동을 몇 가지 유형으로 분류한 후 연령 집단에 따라 우울과의 관계에 차이가 있는지 살펴보는 것이다. 본 연구에서는 노년기를 80세를 기준으로 전기 노인과 후기 노인으로 구분하였는데, 전기 노인은 여전히 바람직한 심리ㆍ사회적 특성을 유지하고 있는 시기인 반면 후기 노인은 노년기의 부정적인 특성이 부각되는 시기이다. 본 연구에서는 사회활동을 공식적 사회활동과 비공식적 사회활동으로 구분하고 각각을 몇 가지 하위 범주로 구분한 후 우울과의 관계를 분석하였다. 본 연구에서 사용한 자료는 2012년 한국고용정보원에서 조사한 고령화연구패널(KLOSA) 4차 자료이며, 분석에 포함된 사례는 3,664명이다. 주요 결과는 다음과 같다. 공식적 사회활동은 우울 수준과 관련이 없는 것으로 나타난 반면, 비공식적 사회활동은 그 하위 범주에 따라 우울과 상이한 관계를 보이고 있다. 자녀전화는 두 집단 모두에서 우울과 부적 관계를 나타낸 반면, 자녀만남은 전기 노인집단에서 우울을 증가시키는 것으로 나타났다. 이와는 달리 친구만남은 전기 노인에서만 우울을 완화시키는 것으로 나타났다. 이러한 결과는 노인이 하나의 집단이 아니라 내적으로 다양한 집단이라는 점을 보여준다. The objective of the study was to analyze the relationship between the depressive symptom and the types of social activity elderly participated. The study postulated that the relationship between two would be different depending on age groups. For the analysis, the author divided age groups into two-young-old (65-79 age old) and old-old (80 or over aged) and the social activities into two-formal and informal activities. The number of the sample for the study was 3,664 persons and the age of sample was 65 or over. The results of the study were as follows. First, formal activities showed no significant relationships with depressive symptom in any age groups. Second, the level of contacting children by phone call showed negative relationship with depressive symptom in all age groups. Third, the level of face to face contact with children showed positive relationship with depressive symptom in young-old group. Fourth, the level of face to face contact with friends showed negative relationship with depressive symptom in young-old group.

      • 전자선 조사야 결합부분의 선량분포 개선을 위한 Acrylic Electron Wedge의 제작 및 사용

        김영범,권영호,황웅구,김유현,Kim Young Bum,Kwon Young Ho,Whang Woong Ku,Kim You Hyun 대한방사선치료학회 1998 大韓放射線治療技術學會誌 Vol.10 No.1

        Treatment of a large diseased area with electron often requires the use of two or more adjoining fields. In such cases, not only electron beam divergence and lateral scattering but also fields overlapping and separation may lead to significant dose inhomogeneities(${\pm}20\%$) at the field junction area. In this study, we made Acrylic Electron Wedges to improve dose homogeneities(${\pm}5\%$) in these junction areas and considered application it to clinical practices. All measurements were made using 6, 9, 12, 16, 20MeV Electron beams from a linear accelerator for a $10{\times}10cm$ field at 100cm SSD. Adding a 1 mm sheet of acryl gradually from 1 mm to 15 mm, We acquired central axis depth dose beam profile and isodose curves in water phantom. As a result, for all energies, the practical range was reduced by approximately the same distance as the thickness of the acryl insert, e.g. a 1 mm thick acryl insert reduce the practical range by approximately 1 mm. For every mm thickness of acryl inserted, the beam energy was reduced by approximately 0.2MeV. These effects were almost independent of beam energy and field size. The use of Acrylic Electron Wedges produced a small increase $(less\;than\;3\%)\;in\;the\;surface\;dose\;and\;a\;small\;Increase(less\;than\;1\%)$ in X-ray contamination. For acryl inserts, thickness of 3 mm or greater, the penumbra width increased nearly linear for all energies and isodose curves near the beam edge were nearly parallel with the incident beam direction, and penumbra width was $35\;mm{\sim}40\;mm$. We decide heel thickness and angle of the wedge at this point. These data provide the information necessary to design Acrylic Electron Wedge which can be use to improve dose uniformity at electron field junctions and it will be effectively applicated in clinical practices.

      • 유방암 방사선치료 시 최적의 방사선치료계획기법에 대한 고찰

        김영범,이상록,정세영,권영호,Kim, Young-Bum,Lee, Sang-Rok,Chung, Se-Young,Kwon, Young-Ho 대한방사선치료학회 2006 대한방사선치료학회지 Vol.18 No.1

        Purpose: A various find of radiotherapy treatment plans have been made to determine appropriate doses for breasts, chest walls and loco-regional lymphatics in the radiotherapy of breast cancers. The aim of this study was to evaluate the optimum radiotherapy plan technique method by analyzing dose distributions qualitatively and quantitatively. Materials and Methods: To evaluate the optimum breast cancer radiotherapy plan technique, the traditional method(two dimensional method) and computed tomography image are adopted to get breast volume, and they are compared with the three-dimensional conformal radiography (3DCRT) and the intensity modulated radiotherapy (IMRT). For this, the regions of interest (ROI) such as breasts, chest walls, loco-regional lymphatics and lungs were marked on the humanoid phantom, and the computed tomography(Volume, Siemens, USA) was conducted. Using the computed tomography image obtained, radiotherapy treatment plans (XiO 5.2.1, FOCUS, USA) were made and compared with the traditional methods by applying 3DCRT and IMRT. The comparison and analysis were made by analyzing and conducting radiation dose distribution and dose-volume histogram (DVH) based upon radiotherapy techniques (2D, 3DCRT, IMRT) and point doses for the regions of interest. Again, treatment efficiency was evaluated based upon time-labor. Results: It was found that the case of using 3DCRT plan techniques by getting breast volume is more useful than the traditional methods in terms of tumor delineation, beam direction and confirmation of field boundary. Conclusion: It was possible to present the optimum radiotherapy plan techniques through qualitative and quantitative analyses based upon radiotherapy plan techniques in case of breast cancer radiotherapy. However, further studies are required for the problems with patient setup reproducibility arising from the difficulties of planning target volume (PVT) and breast immobilization in case of three-dimensional radiotherapy planning.

        비공식 사회지원망 종류와 삶의 만족도 : 전기 노인과 후기 노인의 차이를 중심으로

        김영범(Kim, young Bum),윤혜경(Yoon, Hye-Gyung),윤현숙(Yoon, Hyun Sook) 지역사회학회 2019 지역사회학 Vol.20 No.3

        본 연구의 목적은 비공식 사회지원망과 노인이 인식하는 삶의 만족도 사이의 관계가 전기 노인과 후기 노인에게서 차이를 보이는지 분석하는데 있다. 본 연구는 비공식 사회지원망을 가족·혈연지원망과 친구·이웃지원망으로 구분한 후 각각의 크기가 삶의 만족과 유의미한 관계를 보이는지 전기 노인과 후기 노인으로 나누어 분석하였다. 본 연구에서는 춘천 지역 거주 65세 이상 노인 1,000명에 대한 조사 결과를 활용하여 분석을 실시하였다. 본 연구의 주요한 결과는 다음과 같다. 첫째, 나이가 들수록 삶의 만족도는 증가하지만 후기 노년기에는 나이와 유의미한 관계를 보이지 않는 것으로 나타났다. 건강관련 요인 중 외로움, 우울이, 사회경제적 요인 중 소득은 노인의 삶의 만족도에 영향을 주는 것으로 나타났다. 둘째, 지원망 전체 크기는 노인의 삶의 만족과 유의미한 관계를 보이는 것으로 나타났다. 셋째, 전기 노인의 경우 가족·혈연이나 친구·이웃지원망의 크기가 삶의 만족과 유의미한 관계를 보이지 않는 반면 후기 노인의 경우 가족 지원망의 크기는 삶의 만족도와 유의미한 관계를 보이는 것으로 나타났다. The purpose of the study was to analyze the relationship between the types of informal social support networks and level of life satisfaction perceived by the elderly. The study focused on the difference of the relationship between the young old and old-old elderly group. This study divided informal social support network into family support network and non-family support network, and analyzed the relationship of each social support network size and life satisfaction in young old and old-old groups. In this study, we analyzed the survey results of 1,000 elderly people over 65 years of age living in Chuncheon. The main results of this study were as follows. First, life satisfaction increased with age, but there was no significant relationship with age in later age. Income among socioeconomic factors and loneliness and depression among health-related factors were found to affect the life satisfaction of the elderly. Second, the overall size of the support network was found to have a significant relationship with the life satisfaction of the elderly. Third, the size of family or non-family support network showed no significant relationship with life satisfaction in the young old elderly group, while the size of family support network had a significant relationship with life satisfaction in the old-old elderly group.

      • 4MV X-선을 이용한 조직보상체 두께비 연구 및 응용

        김영범,정희영,권영호,김유현,Kim Young-Bum,Jung Hee-Young,Kweon Young-Ho,Kim You-Hyun 대한방사선치료학회 1996 大韓放射線治療技術學會誌 Vol.8 No.1

        A radiation beam incident on irregular or sloping surface produces an inhomogeneity of absorbed dose. The use of a tissue compensator can partially correct this dose inhomogeneity. The tissue compensator should be made based on experimentally measured thickness ratio. The thickness ratio depends on beam energy, distance from the tissue compensator to the surface of patient, field size, treatment depth, tissue deficit and other factors. In this study, the thickness ratio was measured for various field size of $5cm{\times}5cm,\;10cm{\times}10cm,\;15cm{\times}15cm,\;20cm{\times}20cm$ for 4MV X-ray beams. The distance to the compensator from the X-ray target was fixed, 49cm, and measurement depth was 3, 5, 7, 9 cm. For each measurement depth, the tissue deficit was changed from 0 to(measurement depth-1)cm by 1cm increment. As a result, thickness ratio was decreased according to field size and tissue deficit was increased. Use of a representative thickness ratio for tissue compensator, there was $10\%$ difference of absorbed dose but use of a experimentally measured thickness ratio for tissue compensator, there was $2\%$ difference of absorbed dose. Therefore, it can be concluded that the tissue compensator made by experimentally measured thickness ratio can produce good distribution with acceptable inhomogeneity and such tissue compensator can be effectively applied to clinical radiotherapy.

      • 방사선치료시 물리학적 반음영의 검토

        김영범,황웅구,김유현,Kim, Young-Bum,Whang, Woong-Ku,Kim, You-Hyun 대한방사선치료학회 1994 大韓放射線治療技術學會誌 Vol.6 No.1

        Proper evaluation about the penumbra is very important to improve the efficacy of radiation theraphy. There are two kinds of physical penumbra, geometric penumbra and transmission penumbra. In this study, we evaluated the variation of physical penumbra according to the varing enery level, changing the field size and depth. Physical penumbra width was decreased as the source size decreased, and as the SDD increased, but the consideration about the scatter radiation and mechanical stability is an important factor. For the two adjacent beams, upper collimator should be used and especially for Co-60 unit, it is efficient to use the extended collimator.

        해상 환경에서의 무선 이동 통신을 위한 선박용 Ad-hoc 네트워크 운용 시나리오

        김영범,장경희,윤창호,박종원,임용곤,Kim, Young-Bum,Chang, Kyung-Hi,Yun, Chang-Ho,Park, Jong-Won,Lim, Yong-Kon 한국정보통신학회 2009 한국정보통신학회논문지 Vol.13 No.10

        육상에서는 기지국을 통해 고속의 무선 통신 시스템을 사용하고 없는 반면, 해상의 경우 기지국을 설치하는데 제약이 따르고, 이로 인해 긴 전송거리를 갖는 저속의 MF/HF 대역 모뎀을 주로 사용 하고 있다. 고속 전송을 위해 해상위성통신이 사용되기도 하지만, 비용이 비싸다는 단점을 가지고 있다. 낮은 비용으로 전송속도를 증가시키기 위해서는 Vehicular Ad-hoc Network (VANET)과 같은 기지국이 없는 상황에서 단말간의 통신이 가능한 네트워크의 구성이 필요한데, 해상의 경우 육상과는 다른 환경적인 특징들을 갖기 때문에 본 논문에서는 해상에서의 Ad-hoc 네트워크를 Nautical Ad-hoc Network (NANET) 이라 칭하며 NANET을 위한 시나리오를 설정하고, 시나리오 별 Multiple Access 및 Duplex 방식을 분석한 후, NANET을 구축하기 위한 주요 후속 연구 주제들을 정리하여 해상 무선 통신 연구를 위한 기본적인 Guide Line을 제시한다. In terrestrial communications, high data rate transmission can be achieved by splitting the coverage area into small cells through base stations and reusing the resource efficiently. However, the geographical features of maritime communications require the long transmission range, and it is not practical to install base station on the sea to set up the similar deployment as the terrestrial communications, so MF/HF band modem with low data rate are currently utilized for maritime communications. And the expensive satellite communication via Inmarsat is the conventional solution for the high data rate transmission on the sea. To reduce the cost, Ad-hoc network is proposed to apply on the sea, which requires no base station for the peer-to-peer communications. In this paper, we denominate this maritime environment specific Ad-hoc network as Nautical Ad-hoc Network (NANET). Furthermore, the deployment scenario for the NANET, and the analysis on multiple access and duplexing schemes for the NANET are discussed in this paper, which serves as the cornerstone for the further NANET research and development.

        자녀와의 지원교환과 노인의 부양책임감에 대한 인식이 노인의 주관적 안녕감에 미치는 영향

        김영범(Young Bum Kim),박준식(Park Joon Shik),이기원(Kee Won Lee) 연세대학교 사회복지연구소 2008 한국사회복지조사연구 Vol.18 No.-

        본 연구의 목적은 자녀와 노부모와의 지원교환과 노인이 느끼는 부양책임감이 노부모의 주관적 안녕감에 미치는 영향을 분석하는 것이다. 본 연구는 독립성을 강조하는 서구의 가치관과는 달리 자녀로부터의 적절한 지원을 바람직한 것으로 여기는 한국의 문화에 주목하여 자녀에 대한 지원 보다는 자녀로부터의 지원이 주관적 안녕감에 긍정적 영향을 줄 것으로 예상하였다. 이와 함께 노인의 부양책임감이 높을수록 기대와 현실의 차이가 증가하기 때문에 부양책임감이 클수록 주관적 안녕감은 낮을 것으로 예상하였다. 본 연구에서는 이를 분석하기 위해 서울 및 춘천지역 거주 65세 이상 노인 1022명의 조사 자료를 활용하였다. 분석 결과는 다음과 같다. 첫째, 자녀에 대한 노부모의 지원은 노부모의 주관적 안녕감에 유의미한 영향을 주지 못하지만 자녀로부터의 지원은 주관적 안녕감을 증가시키는 영향을 주는 것으로 나타나고 있다. 둘째, 노인이 느끼는 부양책임감이 클수록 주관적 안녕감은 낮은 것으로 나타나, 기대와 현실 사이의 괴리가 주관적 안녕감에 부정적 영향을 주고 있음을 확인하였다. The objective of the study is to analyze the effect of Intergenerational exchange and filial responsibility on subjective wellbeing of elderly in South Korea. The study has two hypotheses. First, according to the studies on elderly in West, because of the value stressed the independence in life, subjective wellbeing of elderly shows positive relationship with support to children, not with support from children. However, in South Korea, people think it normal to have appropriate support from their children. Thus the support from children may show positive relationship with subjective wellbeing of elderly. Second, because of the difference between filial responsibility and reality, level of the filial responsibility may show negative relationship with subjective wellbeing of elderly. For the analysis, the study use data from Hallym Aging Study. The data were collected from elderly over 65years old in Seoul and Chuncheon area. The number of sample was 1022. The results of analysis are in following. First, as hypothesized, subjective wellbeing of elderly shows positive relationship with supports from children. Second, filial responsibility shows negative relationship with subjective wellbeing of elderly.
