This study has been performed to analyse behavioral aspects of the aged living in welfare facilities. In this study, college seniors and social workers were interviewed for their experiences on unforeseen disruptive situations in counselling the aged in the facilities. The results of the interview are as follows: 1.The residents generally welcome visitors but this atmosphere may abruptly turn out to be disinterests once they realize that the visitors are not beneficial. 2. Their conscientiousness is generally higher, but they are more conservative and passive than community residents. 3. They show somewhat abrupt manner when talking to unfamiliar visitors, but expect sudden visits from children and relatives. Overall in this study, it is proposed that one-to-one and face-to-face relationship between residents and visitors be formed so that hospitable communication environment are stabilized.

This study was conducted to evaluate degree of satisfactions for space functions and near environment of Community Elderly Centers among elderly users in Korea. The project was purposed to give the elderly club appropriate functions, so that could solve the deficiency of elderly welfare resources. Korea enters the aging society since 2000, as defined by U.N., i.e. over than 7% of the elderly among total population. Korea is expected that present capability of welfare resources are not enough to cope with such a dramatic increase on elderly population. In addition, economic crisis and deficient health resources also provide negative explanations on why the government could not expand health and welfare resources for solving the elderly needs and why should have find substitutive mechanism. Thus, as a way of securing the elderly care resources, this study tested a question as that if the elderly clubs could be utilized as health and welfare community centers for solving care needs of the elderly. The elderly clubs shows the highest number of facilities, 36,340 in nation-wide, which is almost equivalent to the number of villages in Korea Every village has at least more than one of the elderly club, and about 5% of the elderly users stay in the welfare centers all day long as if it were their home. Therefore, it is very imperative that the space functions be evaluated as a second home. In this study, 252 elderly users were interviewed about how satisfied with the space functions and near environment of the welfare centers, and certainly it was observed that there are some gender and marital status differences on the perceptions of management and community welfare facilities of the center. Finally in this study, it is proposed that the welfare centers be separated for the users on the basis of gender and marital status.

This study has been performed to investigate life attitudes and satisfaction on welfare services of the low income elderly. In this study, 101 subjects aged 60 or more were selected in small cities in rural counties, and asked about how they feel with general life, neighboring environment they, and welfare services delivered by social workers in their residential communities. In general, eventhough they were aware of their low socioeconomic status and therefore unqualified life quality, they were seen to maintain positive attitudes on daily family lives and welfare supports. However, it was also observed that the quality of service delivered to their door was not commensurate with their patience and cooperation for waiting at service centers. Therefore in this study, it is mainly proposed that process for accepting client request and deliver a proper service be more exepedited and efficiency oriented.

최영세,박효국,김세영,김주호,이상규,윤종원,조정희,Choi, Young Se,Park, Hyo Kuk,Kim, Se Young,Kim, Joo Ho,Lee, Sang Kyoo,Yoon, Jong Won,Cho, Jung Heui 대한방사선치료학회 2017 대한방사선치료학회지 Vol.29 No.2

목 적: 표적의 길이가 긴(length) 환자의 용적회전변조 방사선치료(V-MAT) 시 회전방향 오차의 크기에 따른 선량차이 경향을 $HexaPOD^{TM}$ evo RT system(6DoF couch)을 통해 알아보고 그 유용성을 평가하고자 하며, 이에 따른 회전오차 보정의 필요성을 제안하고자 한다. 대상 및 방법: 본원에서 치료를 받은 Esophagus cancer와 SCL을 포함한 Breast cancer 환자 중 HexaPOD 6DoF(Six-Degree of Freedom) couch를 사용한 10명을 대상으로 하였다. 6DoF couch를 이용하여 Rx(pitch), Ry(roll), Rz(yaw) 방향의 회전오차의 적용여부에 따른 선량차이를 알아보기 위하여 x, y, z축에 대한 자세오차를 확인하고, 자세 회전오차 값을 6DoF couch에 부여 임의의 오차를 발생시켜 변형된 선량계측 품질보증(Delivery Quality Assurance, DQA)을 시행, 점 선량과 감마값을 비교 분석하였다. 추가적으로 3cm의 직경에 5, 10, 15, 20 cm의 길이를 가진 각각의 표적의 치료계획에 회전오차의 크기를 $1^{\circ}$ 간격으로 적용한 후, 표적의 길이와 회전오차의 종류 및 크기에 따른 감마통과율의 변화양상을 확인했다. 결 과: 자세 회전오차가 적용된 경우의 점 선량과 감마통과율의 평균오차는 각각 Rx 방향에서 $2.50{\pm}1.11%$, $84.1{\pm}7.39%$, Ry 방향에서 $2.36{\pm}1.16%$, $81.0{\pm}8.49%$, Rz 방향에서 $2.35{\pm}1.10%$, $84.4{\pm}6.99%$를 나타냈다. 또한, 표적의 길이와 회전오차의 종류 및 크기에 따른 감마통과율 분석 결과 Ry 방향을 제외한 Rx와 Rz 방향에서 회전오차가 커질수록 감마통과율은 전반적으로 감소하는 경향을 보였으며, 특히 10 cm의 표적, Rz 방향으로 $2.5^{\circ}$ 회전오차가 부여된 경우에서 가장 낮은 감마통과율인 74.2 %를 나타냈다. 결 론: 표적의 길이가 긴 치료부위의 용적회전변조 방사선치료 시 회전오차의 보정은 필요하며, 6DoF couch의 사용은 환자자세의 재현성과 치료의 질적 효율을 높일 것으로 사료된다. Purpose: To evaluate the usefulness of the $HexaPOD^{TM}$ evo RT system(6DoF couch) and the tendency of dose difference according to size of rotational direction error for volumetric rotational modulated radiotherapy(V-MAT) in patients with long target lengths. Therefore, it is suggested to recommend the need for rotational error correction. Materials and Methods: Ten patients with Esophagus cancer or Breast cancer including SCL treated with HexaPOD 6DoF(Six-Degree of Freedom) couch were included in this study. 6DoF couch was used to measure the difference in dose according to the rotation error in the directions of Rx(pitch), Ry(roll), and Rz(yaw). Each rotation error was applied. Positioning variation on x, y and z axis was verified and random variations were made by 6DoF couch with positioning variation. Modified DQA is conducted and point dose and gamma value are analyzed and compared. In addition, after applying the rotation error every $1^{\circ}$ to treatment plans of each target with a diameter of 3 cm, 5, 10, 15, and 20 cm respectively, gamma passing rate is being monitored by its aspect of change according to types and sizes of the target length and rotation error. Results: Mean error of the point dose and Gamma passing rate when the position variation was applied were $2.50{\pm}1.11%$ and $84.1{\pm}7.39%$ in the Rx direction, $2.36{\pm}1.16%$, and $81.0{\pm}8.49%$ in the Ry, $2.35{\pm}1.10%$ and $84.4{\pm}6.99%$ in the Rz direction, respectively. As a result of analysis on gamma passing rate according to types and sizes of the target length and rotation error, the gamma passing rate tended to decrease with increasing rotation error in the Rx and Rz directions except Ry direction. In particular, the lowest gamma passing rate (74.2 %) was in the case of $2.5^{\circ}$ rotation error in Rz direction of the target of 10 cm. Conclusion: The correction of the rotational error is needed for volumetric modulated radiotherapy of the treatment area with a long target length, and the use of 6DoF couch will improve the reproducibility of the patient position and the quality of the treatment.

본 연구는 광양제철소 임해준설매립지에 자생하는 식물분포와 토양환경요인의 특성을 규명하고, 식물분포와 토양과의 상관관계를 밝힘으로써 향후 생태적 조경의 활용방안을 제시하고자 한다. 연구대상지는 해수변으로부터 시작하여 표고 15m에 이르는 지역으로 임해준설매립지내 조사지역 1,2,3 및 4는 전형적인 염습지의 특정을 나타내었다. 조사지역의 총 출현종수는 1, 2, 3, 4, 5지역별로 각각 13, 15, 22, 27, 35종으로 증가하는 것으로 나타났으며, 염생식물은 감소하고 중성식물은 증가하는 경향을 나타내었다. 각 조사지역별 표층토양(O ~2Ocm)의 물리, 화학적 특성을 분석한 결과, 조사지역 1 에 서 조사지역 4로 이동함에 따라 탈염이 진행되면서 토양산도 및 전기전도도는 낮아지고, 영분, 유효인산, 칼륨, 염소, 칼숨, 마그네숨 등은 함량이 감소된 반면, 전 질소, 미사, 점토함량은 증가하는 경향을 보여주었다. 이는 임해준설매립지에서 자연강우에 토양이 장기간 노출되면서 염분과 관련된 토양환경인자들이 변화하는 것을 잘 나타내는 것이다. 이러한 분석 결과, 염분과 관련된 인자들이 연구대상지의 식물분포의 변화를 유도한 주요한 영향요인으로 밝혀졌다. By analyzing specific plant distributions and physicochemical characteristics of topsoil in a reclaimed dredging area, baseline data was found of natural landscape planting sites, and developing dredged fill ground. The reclaimed dredging area is five different stands (1, 2, 3, 4 and 5) which were examined in this research. They are located from sea level to 15 meters in altitude and exhibited typical characteristics of the salt marsh in Gwangyang Bay. Species with high constancy in the vegetation on the reclaimed soil were classified into four stages. A total of 12, 15, 22, 27 and 35 different plant species were found and also increased in stands 1, 2, 3, 4 and 5, respectively. Moving from stand 1 to 5, halophytes decreased and non-halophytes increased. Desalination at each stage of the reclaimed dredging area was a driving force affecting the performance and distribution of halophytes and non-halophytes. Overall, 35 quadrats of soil were selected and analyzed for specific physicochemical characteristics of topsoil between O${\sim}$20cm. Results of the physicochemical analysis such as altitude, slope, vegetation and kind of reclaimed dredging soil, exhibited irregular increases or decreases. As survey areas moved from stand 1 to 4, desalination areas, soil acidity, electric conductions, content of salinity, available phosphorus, potassium, chlorine, calcium, and magnesium indicated decreasing patterns; however, total nitrogen, silt, and clay content increased. Cluster analysis and PCA by environmental data within the stands clearly showed five distinct vegetation patterns on the tested reclaimed area. These results indicate that the differences of performance and distribution of vegetation are due to the SAR in the reclaimed soil and related to the natural survival strategy at the given hostile habitat.
