Purpose. Despite many smoking cessation programs, many patients with CAD continue to smoke or re-smoke. The processes of change and self-change for smoking cessation is emphasized. The purpose of present study was to investigate decisional balances and processes of change according to stages of change for smoking cessation in the patients with CAD. Methods. This descriptive study was performed using the self-reported questionnaires from 157 male patients with CAD who have smoking experiences. The questionnaires consisted of decisional balances toward smoking (pros/cons) and processes of change including 7 factors. Results. 45.2% of the subjects had myocardial infarction and 54.8% for angina pectoris. Major stages of change were maintenance, contemplation, and precontemplation in 62%, 14%, and 18% respectively. The mean score of pros smoking was 31.07 and cons smoking was 32.52. The mean scores of processes of change were high in all 7 factors, especially in self determination. The pros smoking in precontemplation stage was significantly higher than those in other stages. Between contemplation and precontemplation stages, processes of change showed significant differences in stimulus control, self determination, information management, and dramatic relief. Conclusion. This study suggests that decisional balances and processes of change are stage-specific. As this study, smoking cessation program in the patients with CAD must put priority on the patients group in pre-contemplation and contemplation stages, and stress self determination and dramatic relief.

Traditional business process management systems provide verification tools of process models to deploy and automate the models. However, there are not so many studies on how to maintain systematically collaborative process models such as supply chain processes when companies are willing to change and update the collaborative process models. In this paper, we analyze change patterns of collaborative processes and declare 19 change patterns. In addition, we apply the change patterns to the process interoperability patterns in order to identify the change problems in case of independent process changes of collaborative processes. As a result, we devise an independency checking algorithm of process changes in collaborative processes.

Purpose: The purpose of this study was to investigate smoking cessation behavior of male taxi drivers in Korea on the basis of the Transtheoretical model(TTM), and to validate the usefulness of TTM. Method: Data were collected using a self-reported questionnaire including smoking history and major factors of TTM from 208 subjects who were current smokers or ex-smokers. Data were analyzed by descriptive statistics and ANOVA. Result: Most subjects ($85.1\%$) were current smokers. Stages of change were precontemplation ($44.7\%$) and contemplation ($27.4\%$). Subjects in precontemplation stages had the lowest mean score in processes of change and the highest mean scores in decisional balance(pros) and temptation(positive affective, habitual/craving). According to stages of change, there were statistically significant differences in processes of change, decisional balance, and temptation. Conclusion: This study supported the generalization of TTM. As this study showed that the subjects didn't have motivation in smoking cessation, applying tailored smoking cessation programs for taxi drivers is needed.

Purpose: The purpose of this study was to compare variables related to weight control between normal weight and overweight/obese female adolescents. Methods: This study is a supplementary analysis using a total of 293 female adolescents in Seoul. Data were collected through self-report questionnaires on the topics of stages of change, processes of change, and the decisional balance pertaining to weight control. Body weight and height were also measured. Results: There was a significant difference in the stages of change between the normal weight and overweight/obese groups. Of 12 processes of change, 9 processes were significantly higher in the overweight/obese group than in the normal weight groups. Also, female adolescents who were overweight or obese had significantly higher pros and eating efficacy scores comparing to those in the normal weight group. Conclusion: The findings of this study suggest that overweight/obese female adolescents, especially those in the action stage need supports to continue their weight control behaviors. In addition, a weight control program for female adolescents should emphasize their participation in physical activities in addition to their dietary control efforts.

Purpose: The purpose of this study was to identify the effects of a smoking cessation program on processes of change, situational temptation, and decisional balance in male university student smokers. Method: Utilizing a quasi-experimental design, 78 male university students consisted of an experimental group (n=48) and a control group (n=30). A smoking cessation program was applied to the experimental group for a period of 6 months while no program was given to the control group. Study questionnaires were used to measure outcome variables before and after the program. Descriptive analysis, $\chi^2$-test, t-test, and ANCOVA were used with SPSS 18.0 program for data analysis. Results: After treatment with this program, the experimental group showed significantly higher scores for processes of change (experiential and behavioral processes of change) than the control group. The experimental group also showed significantly lower scores for situational temptation (positive social, negative affect, and habit strength). Conclusion: The smoking cessation program may have positive effects on process of change and smoking temptation for male university student smokers.

본 연구는 2D 기반의 동적 공간모형(dynamic spatial landscape models)을 통해 지표 변화 과정을 이해하고 예측할 수 있는 방법론을 제시하는데 그 초점을 두고 있다. 동적 공간모형 에 기반한 연구는 크게 지표의 공간 패턴에 대한 모형화와 변화 과정에 관한 모형화 및 모의로 구성되어 있는데 지표 변화와 관련된 규칙은 변화 원인과 그 과정에 따라 다르게 정의될 수 있다. 이때 지표 패턴의 이질성은 변화와 밀접한 관계를 가지고 있기 때문에 연구 지역의 GIS 맵으로부터 공간 패턴의 특성을 모형화 하여 이를 기반으로 변화에 관한 동적 공간 모형이 적용되어야 한다. 본 논문에서는 이를 위한 모형기반 접근법이 설명되어 있고 자연 화재로 인한 지표 변화 과정에 적용되어 동적 공간 모형이 개발되었다.

Numerical model introduced in this study combines wave refraction-diffraction, breaking, bottom friction, lateral mixing, and critical shear stress and three sub-models for simulating waves, currents, and bottom change were briefly discussed. Simulations of beach processes and harbor sedimentation were also described at the coast neighboring Bangpo Harbor, Anmyundo, Chungnam, where the area has suffered from accumulation of drifting sand in a small fishing harbor with a wide tidal range. We also made model test for the case of a narrow tidal range at Nakdong river's estuary area to understand the effect of water level variation on the littoral drift. Simulations are conducted in terms of incident wave direction and tidal level. Characteristics of wave transformation, nearshore current, sediment transport, and bottom change are shown and analyzed. We found from the simulation that the tidal level impact to the sediment transport is very important and we should apply the numerical model with different water level to analyze sediment transport mechanism correctly. Although the model study gave reasonable description of beach processes and harbor sedimentation mechanism, it is necessary to collect lots of field observation data, including waves, tides and bottom materials, etc. for better prediction.

In the past, the predictions of beach processes and harbor sedimentation were mainly relied on the hydraulic model tests and empirical methods. In recent years, however, as computers have come into wide use, more accurate models have gradually been developed and thus replaced those conventional methods. For prediction of topographical change near the coastal area, we need informations of wave and current conditions in the numerical model which should be calculated in advance. Numerical model introduced in this study combines wave refraction-diffraction, breaking, bottom friction, lateral mixing, and critical shear stress and three sub-models for simulating waves, currents, and bottom change were briefly discussed. Simulations of beach processes and harbor sedimentation were also described at the coast neighboring Bangpo Harbor, Anmyundo, Chungnam, where the area has suffered accumulation of drifting sand in a small fishing harbor with a wide tidal range. We also made model test for the new layout of the harbor and planned south breakwater for preventing intrusion of sand. Although the model study gave reasonable description of beach processes and harbor sedimentation mechanism, it is necessary to collect lots of field observation data, including waves, tides and bottom materials, etc. for better prediction.

Purpose. The purpose of this study was to differentiate the change in exercise behavior into different stages and to investigate differences in the process of change, self efficacy, decisional balances and depression according to the stages of exercise behavior change among middle aged women in Korea by using the transtheoretical Model. Methods. A convenience sample of 434 middle aged women (40-64 years) completed measures of all transtheoretical model constructs involved in exercise behaviors (stages and processes of exercise behaviors change, self efficacy and decisional balance) and depression. The data were analyzed by using the SPSS 10.0 program including descriptive statistics, and one-way ANOVA. Results. The subjects were distributed in each stage of change in exercise behaviors: pre-contemplation (n = 106; 24.4%), contemplation (n = 126; 29%), preparation (n = 88; 20.3%), action (n = 51; 11.8%), and maintenance (n = 63; 14.5%). The processes of change, pros (advantages of behaviors), self-efficacy and depression were significantly differentiated across the stages of exercise behavior change. Cons(disadvantage of behaviors) was not significantly differentiated across the stages of exercise behavior change. Conclusions. Results of this study suggested that discriminating of processes of change, self-efficacy, decisional balance, and depression could provide positive information to people about the stages of change in exercise behavior. Therefore, in designing interventions, the stage of a client's exercise behaviors change needs to be assessed prior to application of intervention programs in order to increase and maintain exercise behavior in middle aged women.
