This study of the Wholeness Program relevant to dementia behavior and verification of buffering effects. For the purpose of this, among those who were attending Day Care Centers belonging to Seniors Welfare Center of M1 and M2 located in Seoul. Among those who met all these requirements, 40 senior citizens were finally selected. After carrying out a preliminary test to the selected subjects, 20 elderly of Seniors Welfare Center of M1 were randomly placed as an experimental group, while other 20 people of Seniors Welfare Center of M2, as a control group. The Wholeness Program relevant to dementia behavior was carried out from March 14 to May 30 of 2016, for 12 weeks, twice a week. As for the measurement tool, this study depended on the Korean version of Mini Mental State Examination (MMSE-K), the Korean version of Modified Barthel Index (K-MBI) and the Korean version of Geriatric Depression Scale (GDS-K). While the elderly were participating in the Wholeness Program relevant to dementia behavior, they were measured two times in total, before and after the participation in dementia behavior. Based on SPSS-PC (version 21.0), firstly, independent t-test was carried out to understand the homogeneity between the experimental group and the control group. Secondly, matched-pair t-test was carried out between preliminary test and post-test to inquire into the effects of MMSE-K, K-MBI and GDS-K. Thirdly, ANOVA was conducted to confirm the variation (change amount) between preliminary test and post-test. According to the survey results, the Wholeness Program relevant to dementia behavior of the elderly shows overall effects in all spheres of changes of cognitive ability (MMSE-K), changes of physical capacity (K-MBI) and changes of depression level (GDS-K).

The purpose of this study is to shed light on buffering effects of leisure experience on middle-aged women`s marital conflicts and negative emotions. In order to achieve the aim, the study uses questionaries as the quantitative method. 378 valid questionnaires out of 400, targeting middle-aged women who live in Daegu, Gyenonguk, Busan, Gyeongnam, Seoul and Gyeonggi were taken for analysis. The survey was taken between September and November of 2012. There appear to be three distinctive outcomes. First, the subfactors of marital conflicts attribute mostly to depression as significant. The interaction between personal conflict and leisure experience as a subfactor of marital conflicts is statistically demonstrated to be a meaningful explanation of depression. Derived from these outcomes, women`s leisure experience appears to be moderating variable as a buffering effect to the marital conflicts of middle-aged women which influences their depressions. Lastly, the final subfactor of marital conflict is the communal life conflict, however, leisure experiences act as a game changing factor for women`s depression. Thus, a community with high level of leisure experience has a lower relation between communal life and depression. The major contribution of this study is to vindicate the importance of leisure experiences for middle-aged women who bear psychological depression due to marital conflicts. It also leads to a new alternative th help the field of psychological therapy.

사회적 지원 인식과 직무스트레스 및 조직에 대한 태도의 관계 -항공 서비스 산업에의 시사점-

본 연구는 조직 구성원들의 직무태도에 영향을 미치는 중요한 요소 중 하나인 직무스트레스(역할갈등, 역할모호)가 직무만족, 정서적 조직몰입에 어떤 영향을 미치는지에 관하여 검증하고자 하였다. 특히, 상사, 동료의 지원을 포함하는 조직 내부의 사회적 지원이 이들 변수들과 어떤 영향을 미칠 것인가를 살펴보았다. 즉, 사회적 지원이 완충효과, 예방효과, 그리고 대처 효과 중 어떤 효과가 있는지를 검증하였다. 총 102명의 다양한 산업의 직장인들을 대상으로 설문 조사한 실증 결과를 토대로 결과를 도출 하였다. 연구 결과, 조직 내부의 사회적 지원에 대한 인식은 직무스트레스 자체를 줄여주거나(예방효과), 직무스트레스가 존재하더라도 직무만족과 정서적 조직몰입을 높이는 역할(대처효과)을 하는 것으로 나타났다. 한편, 조직 내부의 사회적 지원 인식이 직무스트레스와 직무태도 사이의 부정적 관계를 조절하지는 못 하였기 때문에 완충효과는 없는 것으로 밝혀졌다. 본 연구 결과가 항공 서비스 산업에 줄 수 있는 실무적 시사점과 한계점 및 향후 연구방향에 대하여 논의하였다. This study investigated the relationship between job stresses (role conflict and role ambiguity) and employee`s job attitudes (job satisfaction and affective organizational commitment) concerning the function of social supports from supervisors and co-workers in companies. We hypothesized the effects of internal organizational social supports into three ways: Buffering, preventing, and coping effects. As we expected, the perception of internal organizational social supports negatively related to job stresses (preventing effects) and job attitudes (coping effects). However, it did have buffering effect in that it did not moderate the relationship between job stress and job attitudes. Practical implications, limitations, and future research for aviation service industry suggestions were discussed.

N-benzoyl-4-bromoimidazole의 가수분해반응에 미치는 촉매효과

김혜경,이종팔 東亞大學校 環境問題硏究所 2005 硏究報告 Vol.27 No.1

The hydrolysis reaction of N-benzoyl-4-bromoimidazole was investigated by means of spectrophotometrically in water containing 0.5M KCl at 25℃. The pH-rate profile has been observed H_(3)O^(+)catalyzed reaction below pH 4.0, OH^(-) catalyzed reaction above pH 8.0 and pH independent reaction between pH 4.0 and pH 8.0 The rate accelerating effect by the substituent of the leaving group in the OH^(-) catalyzed reaction shows small in comparison with the substrate having the unsubstituted same leaving group. The D_(2)O solvent isotope effect is observed in the pH independent reaction. This result could be explained that nuclcophilic attack of water might be assisted by general base catalysis involving a second water molecule. This explanation is in accord with the calculated values of activation parameters, that is, the value of the activation entropy shows much larger than that of the activation enthalpy. The most sensitive buffer in the hydrolysis reaction is the cacodylate buffer.

The Study on Precautionary Motivation to Bank Risk Increment based on the Capital Buffer Theory: Evidence from Banks in OECD Countries

서지용 한국자료분석학회 2015 Journal of the Korean Data Analysis Society Vol.17 No.5

This study is aiming at examining the capital buffer theory by testing the relationship between the level or the change of capital buffer and risk level with time lag. Based on the bank data in 12 Organization for Economic Cooperation and Development (OECD) countries, the empirical estimation with generalized method of moment is applied to 3-type specification model. The main results from the empirical test are as follows. First, this study shows that there exists pivotal evidence supporting the capital buffer theory suggested by Peura, Keppo (2006) and Jokipii, Milne (2011) against the moral hazard theory. Second, the profitability of banks contributes to expansion of capital buffer. Third, provision plays a role in insurance function by lowering the level of capital buffer. Fourth, as far as the asset size effect is concerned, the bigger the bank is, the lower the capital buffer is because of recapitalization option. As a result, the mechanism of precautionary motivation is available for OECD banks, and the evidence supports Konishi, Yasuda (2004) arguing that banks show the risk avert behavior if capital regulation pressure is strong.

Control of Threshold Voltage for Top-Gated Ambipolar Field-Effect Transistor by Gate Buffer Layer

Khim, Dongyoon,Shin, Eul-Yong,Xu, Yong,Park, Won-Tae,Jin, Sung-Ho,Noh, Yong-Young American Chemical Society 2016 ACS APPLIED MATERIALS & INTERFACES Vol.8 No.27

<P>The threshold voltage and onset voltage for p-channel and n-channel regimes of solution-processed ambipolar organic transistors with top-gate/bottom-contact (TG/BC) geometry were effectively tuned by gate buffer layers in between the gate electrode and the dielectric. The work function of a pristine Al gate electrode (-4.1 eV) was modified by cesium carbonate and vanadium oxide to 2.1 and 5.1 eV, respectively, which could control the flat -band voltage, leading to a remarkable shift of transfer curves in both negative and positive gate voltage directions without any side effects. One important feature is that the mobility of transistors is not very sensitive to the gate buffer layer. This method is simple but useful for electronic devices where the threshold voltage should be precisely controlled, such as ambipolar circuits, memory devices, and light -emitting device applications.</P>

A Study on Competition Analysis in Retail Distribution Industry Using GIS in Seoul

YOO, Byong-Kook,KIM, Soon-Hong Korea Distribution Science Association 2021 유통과학연구 Vol.19 No.3

Purpose: This study aims to utilize geographic data to analyze how various retail formats of large-scale stores around the traditional market affect the performance of the traditional market in Seoul, Korea. Research design, data, and methodology: The two types of catchment areas were demarcated (circle of 1km radius and Thiessen polygon) for each traditional market, and the large-scale stores located within each catchment area were identified for 153 traditional markets in Seoul, Korea. Additionally, multiple regression analysis was utilized. Results: The results revealed that the influence on the performance of the traditional markets were different depending on the retail format of the large-scale stores. Large discount stores were found to have a negative effect on the sales and the visitors of traditional markets, whereas complex shopping malls and department stores had a positive effect on the traditional markets. Conclusions: As a result of the differences in the retail format such as product categories and leisure functions, the impact of some large-scale stores on the traditional market may have a greater agglomeration effect than the consumer churn effect. Therefore, it is suggested that in the regulation of these large-scale stores, the differences in retail format should be considered for the future.

대학생의 암묵적/외현적 자존감이 시험 후의 감정에 미치는 영향 : 특히 암묵적 자존감의 완충 효과에 착안하여

후지이쓰토무 성신여자대학교 인문과학연구소 2016 人文科學硏究 Vol.34 No.-

본 연구의 목적은 간접적인 방법으로 측정되는 암묵적 자존감이 부정적인 감정을 억제하는 암묵적 자존감의 완충 효과(buffering effect; Greenwald & Farnham, 2000)가 한국에서도 관찰되는지 그 여부를 살펴보는 것이다. 117명의 대학생 (평균 연령21.33세, 표준 편차2.03) 을 대상으로 외현적·암묵적 자존감이 중간 시험과 기말 시험 후의 감정에 미치는 영향을 경로 분석을 통하여 검증하였다. 그 결과, 기말 시험 후의 부정적인 감정에 대해 암묵적 자존감의 유의한 부적 영향이 관찰되었으며 (b*=-.36. p<.05), 암묵적 자존감의 완충 효과가 나타났다. 또한 본연구에서 암묵적 자존감의 지표로 사용한 “이름의 취향 (Gebauer, Riketta, Broemer, & Maio, 2008)” 을 측정하는 방법은 종래부터 사용되어 온 Name Letter Task (Nuttin, 1985) 와 유의한 긍정적 상관을 보였으며 (r = .28, p<.05), 3개월의 간격을 둔 재검사 신뢰도도 적절한 수준으로 나타났다 (r = .73, p<.01). 따라서 이는 향후 연구에서도 활용가능한 신뢰롭고 타당한 측정 방식임이 입증되었다. 마지막으로, 본 연구의 과제와 전망을 논의하였다.

Study of CO₂⁺(CO₂)_n Cluster in a Paul Ion Trap

Karimi, L.,Sadat Kiai, S.M.,babazaheh, A.R.,Elahi, M.,Shafaei, S.R. Korean Society for Mass Spectrometry 2019 Mass spectrometry letters Vol.10 No.1

In this article, the properties of ${CO_2}^+(CO_2)_n$ clusters in a Paul ion trap have been investigated using mass-selective instability mode which conducted by chosen precursor ions, mainly $Ar^+$ and ${CO_2}^+$ produced by a mixture of Ar and $CO_2$. Exposure of ${CO_2}^+$ ions to $CO_2$ molecules, lead to the formation of ${CO_2}^+(CO_2)_n$ clusters. Here, Ar gas react as a buffer gas and lead to form ${CO_2}^+(CO_2)_n$ cluster by collisional effect.
