The purpose of this study was to develop the Post-bereavement Growth Inventory(PBGI) for the elderly and to evaluate its validity. The items for developing PBGI were compiled from a literature search, content validity review, and a preliminary survey. A main survey of 308 widowed persons(aged 60+) was conducted. The results were as follows. First, an exploratory factor analysis revealed six factors of the PBGI. The results of the confirmatory factor analysis supported a five-factor structure for the final 24 scale items of scale. Second, in terms of concurrent validity, the PGBI compared favorably with the "Personal Growth" scale from The Hogan Grief Reaction Checklist (HGRC: Hogan and Schimdt, 2001). Third, the results of contrast group validity tests demonstrated that the group scoring in the upper 30% on the scales of Psychological Well-being (PWB, Ryff and Keyes, 1995) and the Grief Reaction Inventory (GRI: Remondet and Hansson, 1987) showed a significantly higher degree of post-bereavement growth (PBG) than the group scoring in the lower 30%. Fourth, Cronbach's ${\alpha}$ values for the five factors were between .649-.856 and .907 overall, indicating high internal consistency. Finally, education had the most significant influence on PBG. All results indicated the high validity of the PBGI. The findings from this study could provide the rationale for practical interventions from a growth-oriented perspective for widowed persons, as well as an objective assessment tool for practitioners in clinical areas.

This study purposes to explore the growing process through spousal bereavement in later life, and to develop the theory. A qualitative research was conducted, and the participants were 17 seniors. The analysis according to Strauss and Corbin's grounded theory(1998), resulted in 143 concepts, 43 subcategories, and 19 categories. Range analysis according to paradigm showed that the causal conditions were 'marital relationships', 'independent/dependent tendencies', and 'emotional readiness for the death of a spouse', and the phenomena were 'depression', 'hopelessness', 'daily stress', 'psychological intimidation', 'regret', and 'sense of being freed'. The contextual conditions that affect these phenomena were 'desire for intimate personal relationships' and 'desire to maintain independence'; the action/interaction strategies to manage the phenomena were 'facing reality' and 'efforts for construction of the new life'; and the mediating conditions that promote or suppress these action/interaction strategies were 'social support' and 'spirituality'. The results were 'reconstruction of the meaning in life', 'increase in self-esteem', 'reinforcement of social network' and 'embrace and acceptance'. Furthermore, when personal growth after bereavement of a spouse was analyzed focusing on changes over time, the growth process consisted of three steps: 'sadness and despair', 'embracing and moving forward', and 'personal growth'. The pattern analyses were performed to typify recurring relations by category, and 5 types were derived. The results of our study show that personal growth after spousal loss is an integrative process in life after crisis, and can be conceptualized as the process of overcoming the despair that immediately follows the death of a spouse, seeking a new life by actively taking control, and discovering a strengthened self.

The present study aimed at examining the factor structure, reliability and validity of the Korean version of the Continuing Bonds Scale (K-CBS). In study 1, exploratory factor analysis was administered to 293 bereaved adults who had experienced the death of a loved one, and it revealed a single factor structure with 10 items that explained 52.59% of the total variance. The K-CBS showed good internal consistency with Cronbach's alpha of .92. In study 2, confirmatory factor analysis in a different sample of 200 bereaved adults indicated satisfactory standardized regression weights of all items. However, one item had a squared multiple correlation less than .40, hence, this item was discarded, and 9 items remained for the final scale. The single factor model with 9 items displayed a good fit. The K-CBS had strong positive correlation with grief symptoms, and weak positive correlation with depression. After controlling for grief, however, the K-CBS was predictive of a decrease in depression. The K-CBS was positively associated with posttraumatic growth. In addition, significant differences in scores of the K-CBS were shown among groups based on the deceased's relation to the bereaved and expectedness of loss. These results suggest that the K-CBS is a reliable and valid instrument to measure continuing bonds. Finally, implications, limitations, and directions for future research were discussed.

ADCP(Acoustic Doppler Current Profiler)는 유수의 흐름을 방해하지 않으면서 수중에 발사된 음파의 도플러 효과를 이용하여 3차원 유속 측정이 가능한 초음파 유량측정장비이다. 2009년부터 다양한 하천에서 ADCP 사용량이 증가하면서 ADCP를 이용한 유량측정 기법과 현장 적용상의 문제, 자료처리 과정에서의 문제점들이 발생하고 있다. 이런 문제점들을 분석한 결과 다음과 같은 사례들이 나타났다. 첫 번째 하상이 매우 불규칙한 단면의 부적절한 측정 사례, 두 번째 하안 수직벽 존재에 따른 단면의 부적절한 측정 사례, 세 번째 수심 오측이 다수 발생한 측정 사례, 네 번째 유속 프로파일 결측이 다수 발생한 측정 사례, 다섯 번째 통신문제로 인한 주기적인 결측이 발생한 측정 사례, 여섯 번째 홍수기 고농도 유사로 인해 결측이 발생한 사례, 일곱 번째 수중식생의 영향으로 수심 및 유속 프로파일 오측이 발생한 측정 사례, 여덟 번째 이동상 조건이 발생한 측정 사례 등 많은 문제들이 발생하였다. 본 연구에서는 수중식생의 영향으로 수심 및 유속 프로파일 오측이 발생하는 사례에 대해 개선할 수 있는 방안을 연구하였다. ADCP에서 수중에 발사한 음파 중 식생에 부딪친 강한 반사파의 노이즈로 side-lobe현상에 의한 오측 및 결측이 발생한다. 현재 오측 및 결측 자료는 ADCP 제조사별 자료 취득 소프트웨어의 기능에 의존 하거나, USGS의 OSW(Office of Surface Water) Hydroacoustics의 QRev를 이용하여 후처리 과정을 거쳐 측정 자료로 정리하고 있다. 이에 본 연구에서는 노이즈로 인한 side-lobe 현상을 물리적인 방법으로 제거하기 위해 음향 녹음 과정에서 노이즈를 물리적인 방법으로 제거하는 윈드실드와 팝 필터를 고려한 ADCP필터를 개발하여 적용하였다. 이번 연구의 대상지점은 원주시(지정대교)수위관측소로 5월 이후 수중에 식생이 성장하는 지점이다. 먼저 ADCP필터를 제거한 상태에서 측정을 실시하고, 이후 ADCP필터를 장착하여 측정을 실시하였다. ADCP필터 적용의 측정성과에서는 노이즈에 의한 오측 및 결측이 다수 발생하는 것을 볼 수 있고, ADCP필터를 적용한 측정성과에서는 노이즈가 제거되어 오측 및 결측이 개선되는 결과를 볼 수 있었다. 본 연구에서는 수중식생 영향으로 강한 반사파에 의한 노이즈로 side-lobe현상에 의한 ADCP측 정성과의 오측 및 결측을 ADCP필터를 적용하여 물리적인 방법으로 노이즈를 제거 할 수 있다는 결과를 얻었다.
