본 연구는 이선선택법의 일반형인 선택실험법을 적용해 행정중심복합도시 내에 제공될 국립수목원의 중요 속성과 수준을 확인하고, 이들이 조합되어 실제 반영될 경우 각 대안들에 한 경제적 가치를 추정하였다. '자원보전', '교육', '레크리에이션', '시설', '접근성'과 입장료를 속성으로 사용해 주 효과 모델을 정산하기 위한 가상대안을 작성한 후 컨조인트 선택 을 정산한 결과 '자원보전'의 '습지식물'과 '레크리에이션'의 '숲 산책로'가 유의성 있는 수준이었다. 만약 이 수준들이 수목원에 반영될 경우, 응답자들은 각각 약 1,330원과 약 1,507 의 입장료를 더 낼 용의가 있었다. 또한 '자극추구' 성향이 높을수록, 나이가 어릴수록, 소득이 높을수록 수목원 조성에 호의적이 었지만 자연보호에 대한 관여도가 높은 사람들은 부정적이었다. 도시 내 수목원의 경제가치를 실험선택법으로 평가할 후속연구를 위해 중요 속성별 수준과 기준수준에 대한 여러가지의 제언을 추가하였다. The purpose of this research is to identify satisfaction levels of the arboretum which will be provided in the Multifunctional Administrative City and to estimate the economic value of using choice experiments. The attributes were "Preservation", "Education", "Recreation", "Facility", "Accessibility" and the entrance fee. The main effects model was utilized to construct hypothetical alternatives. Calibration of the conjoint choice model revealed that 'wetlands' and 'forest trails' in "Preservation" and the "Recreation", respectively, were significant variables. This result indicates that respondents are willing to pay more for these if they are provided in the arboretum. Also, 'variety seeking' tendency, age, and income level positively influenced the provision of the arboretum. Involvement in preservation of natural environment, however, had a negative influence on the establishment of the arboretum. Because this study is the first attempt to estimate the economic valuation of an urban arboretum using choice experiment, there are several suggestions for future research in terms of determining the base level and inclusion of salient attribute levels.

본 연구는 여행참여와 외상적 사건이 주관적 웰빙에 미치는 영향을 검증하였다. 이를 위하여, 긍정적 감정, 부정적 감정 그리고 삶의 만족도를 종속변수로, 여행참여 여부와 외상적 사건의 회상정도를 독립변수로 하여 유사실험을 설계하였다. 2~3주 간격으로 4번 수집한 종단자료를 반복측정 분산분석으로 분석한 결과, 여행참여는 긍정적 감정과 삶의 만족도를 향상시켰으며, 그 효과는 4주 이상 지속되어 여행은 사람들의 주관적 웰빙을 향상시키는 수단이라는 것을 밝혔다. 외상적 사건을 많이 회상한 집단은 부정적 감정이 사고 직후부터 높아졌으며, 그 영향은 7주 이상 지속되었다. 부정적 사건은 긍정적 사건보다 주관적 웰빙에 미치는 영향력이 강하며, 오래 가는 경향이 있기 때문이었다. 여행과 마찬가지로 도시공원 방문도는 즐거운 여가경험이기 때문에 본 연구의 결과를 적용해 도시공원이 중장기적으로 도시민의 주관적 웰빙을 증가 또는 유지시키며, 스트레스를 완화시킬 수 있는 수단이라는 점을 고찰하였다. This study used a quasi-experimental method to investigate if both travel involvement and the degree of recall of a traumatic event affect subjective well-being. For this, independent variables such as positive affect, negative affect, and life satisfaction were established. Four waves of data collection were performed with two to three weeks intervals, then the collected longitudinal data were analysed by repeated measure ANOVA. The study results indicated that travel involvement increases positive affect and life satisfaction, with the effect lasting four weeks or more, which means that travel is an effective tool to boost subjective well-being. Respondents who thought about a traumatic event more frequently had a much higher negative affect following the disaster, and such increased negative affect was maintained over seven weeks or longer. Therefore, this study finds that negative events produce larger, more consistent, or more lasting effects than positive events. As well as travel participation, visiting an urban park is a pleasurable experience. Therefore, the study also finds that urban parks could be utilized for increasing and maintaining subjective well-being in the middle and long term as well as lessening personal stress.

홍성권,최민규,백용해,노재형,손태성,김성,Hong, Seong-Kweon,Choi, Min-Gew,Baik, Yong-Hae,Noh, Jae-Hyung,Sohn, Tae-Sung,Kim, Sung 대한위암학회 2005 대한위암학회지 Vol.5 No.4

목적: UICC 분류에 의한 2기 위암환자의 임상병리학적 특징에 대하여 알아보고 수술 후 보조요법으로서의 항암, 방사선 치료가 5년 생존율에 미치는 효과에 대하여 알아보고자 하였다. 대상 및 방법: UICC에 의한 병리학적 분류로 병기2기로 판정된 954명을 대상으로 하였다. 항암치료는 수술 후 3주째부터 5-Fluorouracil $400mg/m^2/day$와 Leucovorin $20mg/m^2/day$를 사용하였으며 방사선 치료는 총 4,500 cGy를 25회로 나누어 시행하였다. 결과: 임상병리학적 인자들의 생존율분석에서 환자의 나이, 수술방법, 종양의 크기와 항암 및 방사선 치료가 의미 있는 예후 인자로 분석되었다. 수술 후 항암 방사선 치료에 따른 생존율 분석에서 보조요법을 시행하지 않은 425예의 5년 생존율은 67.9%, 항암 치료 군 187예는 79.8%, 항암방사선 치료 군 342예는 83.6%로 조사되어 통계적으로 유의한 차이를 보였으며(P<0.0001) 항암치료 군과 항암방사선 치료 군과의 생존율 비교에서는 항암방사선 치료 군에서 생존율의 향상을 보여주기는 하였으나 통계적으로 유의하지는 않았다(P=0.1264). 결론: 2기 위암환자에서 환자의 나이, 수술방법, 종양의 크기 및 수술 후 보조적인 항암 및 방사선 치료가 5년 생존율에 영향을 주는 의미 있는 예후인자로 조사되었다. 수술 후 보조요법의 시행이 통계적으로 의미 있는 생존율을 보였으나 임상병리학적 인자들을 고려한 무작위 연구를 통해 그 의미를 검증해야 할 것으로 생각된다. Purpose: This study was conducted to evaluate the effectiveness and the role of post-operative adjuvant chemoradiation therapy in a stage-II (UICC, 1997) primary gastric cancer. Materials and Methods: From September 1994 to December 2004, 954 stage-II gastric-cancer patients were seen, and all of them underwent a curative resection with extensive (D2) lymph-node dissection. The chemotherapy consisted of fluorouracil $(400mg/m^2)$ plus leucovorin $(20mg/m^2)$ for 5 days, followed by 4,500 cGy of radiotherapy for 5 weeks with fluorourcil and leucovorin on the first 4 days and the last 3 days of radiotherapy. Two five-day cycles of chemotherapy were given four weeks after the completion of radiotherapy. The Kaplan-Meier method was used to estimate the survival rates. To assess the importance of potential prognostic factors, we performed univariate and multivariate analyses using a log-rank test and Cox's proportional hazards regression model. A P value <0.05 was considered significant. Results: Univariate analysis revealed that age, tumor size, gross type, surgical method, and postoperative adjuvant therapy had statistical significance. Among these factors, age, surgical method, tumor size, surgical method, and postoperative adjuvant therapy were found to be independent prognostic factors by using a multivariate analysis. The postoperative adjuvant chemotherapy group and the chemoradiation therapy group had survival benefit compared to the surgery-only group. However the chemoradiation therapy group had no significant survival benefit compared to the chemotherapy group. Conclusion: The postoperative adjuvant therapy in stage-II gastric-cancer patients had significant benefit. Therefore, postoperative adjuvant chemoradiation therapy has an acceptable effect. A large-scale, randomized study is needed to evaluate the effectiveness and the role of postoperative radiation therapy.

홍성권,이민우,이상민,안명준,Hong, Sung-Kwon,Lee, Min-Woo,Lee, Sang-Min,Ahn, Myung-June 한국조경학회 2007 韓國造景學會誌 Vol.35 No.5

The new Urban Park Regulation encourages local governments to introduce new types of urban parte such as historic parte, cultural parks and neighborhood parte. However ambiguity among those parks in terms of main facilities and providing recreational programs makes it difficult for local governments, as well as landscape designers and planners, to adopt this new regulations. In this light, the present study aims to search for park facilities and programs defined by the new regulations, in order to satisfy users' demands for those parks with consideration to parks' unique characteristics. For these purposes, a conjoint analysis was carried out with three hundreds participants. Sampled participants include the citizens of Seoul as well as current residents of Paju. The study results indicate that participants would like to have distinctive programs and facilities at these three new types of parks. However, no considerable differences were observed among the levels of programs and facilities participants wish to have, due to unfamiliarity with, in particular, cultural and historic parks. Despite this insignificant difference among attribute levels, study results clearly suggest that residents wold like to have new types of facilities and recreational programs.

This study applied the leisure constraints and negotiation concept to the travel context, especially for traveling in national parks. More specifically, it tries to identify how constraints and negotiation impact a person's travel behavior. The population of this study is the people who intend to visit the national parks for their summer vacations. The data was collected through the panel study, which surveyed the same set of people before and after their trip. Among 527 samples, 39.7% traveled what they planned without any changes. 24.7% did not travel or postponed their trip, and 35.7% enjoyed their vacation but with changes of destination, time or travel periods. These results support that people may use negotiation strategies to overcome their constraints in a travel context. However, there were no statistically significant differences in the impact of constraints on travel behavior among the three groups. The results also confirm that people have to overcome intra-, inter-, and structural constraints for visiting the national parks. Thus, the findings of the study suggest that the concepts of leisure constraints and negotiation is applicable to the travel contexts. Because of its exploratory characteristics, several limitations and cautions were raised.

스키장 방문자들의 가치, 만족, 자아일치성이 재방문의도와 구전의도에 미치는 영향

홍성권,김재현,장호찬,Hong, Sung-Kwon,Kim, Jae-Hyun,Jang, Ho-Chan 한국조경학회 2012 韓國造景學會誌 Vol.40 No.2

우리나라의 스키장들도 경쟁이 심해져 재방문비율을 높이거나 긍정적 구전을 통해 새로운 방문자를 유치해야 하는 상황이 되었다. 본 연구는 스키리조트 방문자들을 대상으로, 가치, 만족 및 자아일치성이 재방문의도와 구전의도에 미치는 영향력을 파악하며, 자기조절초점으로 집단을 세분해 집단 간에 독립변수들의 영향력에 차이가 있음을 확인함으로써 스키장들이 경쟁력 강화할 수 있는 실행방향을 제시하고자 하였다. 현지에서 수집한 자료를 회귀분석한 결과, 사용한 독립변수들은 모두 재방문의도와 구전의도에 영향을 주었다. 만족은 가장 영향력이 큰 변수이었다. 자기조절초점으로 구분한 집단 간에는 재방문의도와 구전의도에 영향을 미치는 변수의 종류가 달라 이 변수가 효과적인 시장세분변수라는 것이 확인되었다. 재방문의도의 경우, 향상초점 집단은 만족만이 영향을 주었으나 예방초점 집단에서는 만족과 함께 자아일치성도 영향을 주었다. 구전의도의 경우에는 향상초점집단에서 자아일치성을 제외하고는 두 집단에서 모든 독립변수들이 영향을 주었다. 분석결과를 바탕으로 방문자들을 유지 또는 유치할 수 있는 실행가능한 몇 가지 대안을 제시하였다. As competition increases, ski resort managers need to search for ways to attract previous visitors or to gain new visitors through word-of-mouth. This study examined the impact of skiers' perceived value, satisfaction and self-congruity on the revisit intention and the positive word-af-mouth intention. Total respondents were also segmented into a promotion-focus and prevention-focus individuals then later examined the differences in the effect of independent variables between groups in order to suggest a managerial direction that will enhance business competency of ski resorts. Results from regression analysis showed that all independent variables utilized in this study were good predictors of two dependent variables. Specially, satisfaction was a highly significant predictor. Promotion and prevention-focused individuals were also differed in evaluating the importance of independent variables for their revisit and word-of-mouth intention. It means that self-regulatory focus is an effective variable for segmentation. More specifically, satisfaction was the only variable influencing the revisit intention for promotion-focused individuals; whereas both satisfaction and self-congruity had significant effects on the revisit intention for prevention-focused individuals. All independent variables had significant effects on the word-of-mouth intention, except self-congruity for promotion-focused individuals. This research suggests several managerial implications on the findings based on the analysis and the characteristics of the visitors.

홍성권,안경진,김종진,Hong, Sung-Kwon,An, Kyoung Jin,Kim, Jong-Jin 한국조경학회 2014 韓國造景學會誌 Vol.42 No.3

본 연구의 목적은 (a) 관광참여가 주관적 안녕감에 미치는 영향력을 검증하고, (b) 관광 참여자와 비참여자 간의 동기, 제한요소 및 개인적 가치의 차이가 주관적 안녕감에 미치는 영향을 이론적으로 설명하기 위함이다. 자료는 여론조사 조사기관이 전국의 주요 도시민들을 대상으로 쿼터샘플링한 후 온라인 조사로 수집하였다. 분산분석과 회귀분석 결과, (a) 참여자들은 자기주도적인 성향이 높아 주관적 안녕감을 높일 수 있는 수단으로 관광을 선택하였으며, (b) 비참여자들보다 관광 동기가 높아 이것을 실천할 수 있는 여행목표를 세웠고, (c) 제한요소가 적어 관광을 쉽게 실행할 수 있어, 관광후의 경험이 전체적인 주관적 안녕감의 향상으로 이어졌다. 또한, 관광 참여 여부와 응답자 자신이 평가한 주관적 경제상태는 주관적 안녕감을 설명하는 주요 변수이었으며, 전체 분산의 21.1%를 설명하였다. 관광을 통해 주관적 안녕감을 향상시킬 수 있는 관리측면에서의 제언과 추후연구를 위한 본 연구의 한계점을 기술하였다. The purposes of this study are two folds: (a) to identify the influences of tourism on subjective well-being, and (b) to understand the roles of travel motivation, constraint and personal value in subjective well-being. A polling agency was employed to select 500 respondents by quota sampling, and data was collected by online survey. ANOVA and regression results showed that tourism participants, compared to the non-participants, have a tendency to select tourism as a mean to enhance their subjective well-being because they are more self-motivated people. Their high motivation to take a trip lead to set up their feasible goals to achieve by the tourism experience and their relatively few constraints help them to have trip easily. The people's satisfaction in tourism contributes to the satisfaction in his/her leisure life, which in turn contributes to his/her subjective well-being. It is also revealed that tourism participation and subjective income level are significant variables affecting subjective well-being, which explain 21.1 percent of the variance. The research suggests various managerial implications to reduce constraints and several ideas for future researches.
