Steam flooding is widely used in heavy oil reservoir with coupling effects among the formation temperature change, fluid flow and solid deformation. The effective stress, porosity and permeability in this process can be affected by the multi-physical coupling of thermal, hydraulic and mechanical processes (THM), resulting in a complex interaction of geomechanical effects and multiphase flow in the porous media. Quantification of the state of deformation and stress in the reservoir is therefore essential for the correct prediction of reservoir efficiency and productivity. This paper presents a coupled fluid flow, thermal and geomechanical model employing a program (MATLAB interface code), which was developed to couple conventional reservoir (ECLIPSE) and geomechanical (ABAQUS) simulators for coupled THM processes in multiphase reservoir modeling. In each simulation cycle, time dependent reservoir pressure and temperature fields obtained from three dimensional compositional reservoir models were transferred into finite element reservoir geomechanical models in ABAQUS as multi-phase flow in deforming reservoirs cannot be performed within ABAQUS and new porosity and permeability are obtained using volumetric strains for the next analysis step. Finally, the proposed approach is illustrated on a complex coupled problem related to steam flooding in an oil reservoir. The reservoir coupled study showed that permeability and porosity increase during the injection scenario and increasing rate around injection wells exceed those of other similar comparable cases. Also, during injection, the uplift occurred very fast just above the injection wells resulting in plastic deformation.

본 연구는 남편과 아내의 은퇴가 상호의존적임을 파악한 연구로, 대다수가 비자발적으로 은퇴하는 경향을 고려하여 배우자의 자발적 은퇴와 비자발적 은퇴가 어떻게 영향을 미치는지 살펴보았다. 이를 위해 한국고령화연구패널 4차년도 응답자 중 노동경험이 있는 75세 이하의 부부 1,038쌍(2,076명)을 대상으로 프로빗분석과 다변량프로빗분석을 실시하였다. 분석 결과, 아내의 은퇴는 남편의 은퇴 결정에 유의미한 영향을 미치는 것으로 드러났다. 배우자의 비자발적 은퇴 역시 유의미한 영향요인으로 나타났는데, 60세 미만 집단에서 남편의 비자발적인 은퇴는 아내의 은퇴에 정적 영향을 미치나, 아내의 비자발적인 은퇴는 남편의 은퇴에 부적 영향을 미치는 것으로 나타났다. 이는 아내의 노동시장 지위가 남편에 종속되는 비율이 높고, 아내가 남편에 비하여 배우자의 건강문제로 은퇴하는 비율이 더 높은 기술통계와 맥을 같이 한다. 본 연구는 기존연구에서 다뤄지지 않은 부부의 상호의존적 영향을 확인하여, 향후 은퇴 연구와 고령자 노동정책에 시사점을 제공할 수 있을 것이다.

본 논문에서는 많은 가스터빈 산업체 및 연구기관에서 연소불안정 현상과 관련된 변수들을 예측하기 위해 가장 보편적으로 이루어지고 있는 열음향 해석 모델에 대한 기술 소개 및 최근의 연구 동향을 분석하였다. 선형 시스템 해석을 통하여 연소 불안정이 발생하는 고유 주파수 및 불안정 초기 성장률의 예측이 가능하다. 이를 위하여 정의된 시스템에서의 음향파와 열발생율 섭동간의 선형 관계식을 선형 음향 이론으로부터 유도할 수 있고, 이 관계식의 해를 구하기 위해서 가장 중요한 부분은 화염 전달 함수로부터 n-${\tau}$ 함수를 구하여 열발생율 섭동 결과에 대한 정보를 얻는 것이다. 현재까지의 연구 결과로부터 선형 특성 해석에는 상당한 진보가 이루어져 왔고, 실제 가스터빈 연소기에 적용하는 노력이 있었으나, 한계 진폭과 과도기 현상 예측을 위해서 요구되는 비선형 동적 특성 모델링 기술 개발은 현재 간단한 연소기와 버너의 적용에 머물러 있는 실정이다. 실제 복잡한 가스터빈과 같은 연소 시스템에 적용되기 위해서는 비선형 경계 조건을 고려한 시스템 동적 특성 연구와 화염의 비선형 거동을 더욱 정확히 설명할 수 있는 전달 함수에 대한 예측 기술이 선행되어야 한다.

This study is concerned about the process capability index in single process. Previous process capability indices have been developed for the consistency with the nonconforming rate due to the process target value and skewness. These indices calculate the process capability by measuring one spot in an item. But the only one datum in an item reduces the representativeness of the item. In addition to the lack of representativeness, there are many cases that the uniformity of the item such as flatness of panel is absolutely important. In these cases, we have to measure several spots in an item. Also the nonconforming judgment to an item is mainly due to the range not due to the standard variation or the shift from the specifications. To imply the uniformity concept to the process capability index, we should consider only the variation in an item. It is the within subgroup variation. When the universe is composed of several subgroups, the sample standard deviation is the sum of the within subgroup variation and the between subgroup variation. So the range R which represents only the within subgroup variation is the much better measure than that of the sample standard deviation. In general, a subgroup contains a couple of individual items. But in our cases, a subgroup is an item and R is the difference between the maximum and the minimum among the measured data in an item. Even though our object is a single process index, causing by the subgroups, its analytic structure looks like a system process capability index. In this paper we propose a new process capability index considering the representativeness and uniformity.

Purpose: The purpose of this study was to identify factors influencing depression of participants in the National Supporting Program for Infertile Couples (NSPI) who received a treatment of IVF (in vitro fertilization) or IUI (intra-uterine insemination). Methods: Using the 2013 NSPI Satisfaction On-line Survey data, secondary data analyses were conducted on 830 cases of IVF and 706 cases of IUI. Descriptive statistics, independent t-test, ${\chi}^2$ test, and logistic regression were performed using SPSS/WIN 21.0. Results: Logistic regression analysis showed that non-pregnancy status (OR=3.05), unexplained infertility (OR=4.29), relationship trouble with spouse (OR=3.57), and relationship trouble with the in-law family (OR=2.78) were significant factors predicting the depression level in the IUI treatment group. Non-pregnancy status (OR=5.28), childlessness (OR=1.92), financial support helpful hardly or not at all (OR=2.63), relationship trouble with spouse (OR=3.28), relationship trouble with the in-law family (OR=2.83), and unemployment (OR=1.60) were significant factors in the IVF treatment group. Conclusion: To reduce infertile women's depression, adequate attention and care need to be paid to these psychological symptoms. It is suggested to develop counseling and couple-therapy along with methods to enhance social support (including that from the in-law's family).

Purpose: This research was conducted to explore the experience of middle-aged women parting with their children and to develop a grounded theory. Method: The participants were 11 women in their 50's who had experienced parting with their children due to schooling, military service and marriage. The grounded theory methodology based on symbolic interactionism was used. Results: 106 concepts, 30 subcategories and 14 categories were derived from the analysis through processes of open coding, axial coding and selective coding. The central phenomenon was 'happy but sad' and the core category was a process of 'independence that is sorrowful yet delightful'. Four types were identified; the independent-type; submissive -type; family-reliant-type ; and fragile-type; based on the attachment to the child, state of mind, satisfaction of the situation, family support system and self-achievement. Conclusion: This research identified that the modern Korean middle-aged women who are considered to be the 'sandwich generation' since they have experienced a turbulent history and the change from a confucian parent-child lifestyle to a couple-oriented one, moved away from an attitude dependent on children in parting with them and started preparing for an independent late life. Based on the results, the verification research is advised on the variables that affect the experience of parting with children.

Purpose: This study was conducted to evaluate the effect of a one-session spouse-support enhancement childbirth education on childbirth selfcefficacy and perception of childbirth experience. Methods: The design of this study was a nonequivalent control group pretest-posttest experiment. The participants in the study were 31 couples in the experimental group and 30 in the control group. The experimental couples were provided with one session on spouse-support enhancement childbirth education the night before delivery. Data were collected at two hours after delivery using the Childbirth Self-Efficacy Inventory (CBSEI) and perception of childbirth experience scale. Data were analyzed using PASW statistics 18 program. Frequencies, percentage, mean, $x^2test$, t-test were used for data analysis. Results: Childbirth self-efficacy significantly increased in the experimental group as compared to the control group, but there was no significant difference in perception of childbirth experience in the experimental group compared to the control group. Conclusion: The results suggest that a one-session childbirth education has beneficial effects on enhancing childbirth self-efficacy in pregnant couples. A one-session spouse-support enhancement childbirth education is recommended as an effective nursing intervention to promote couple's childbirth self-efficacy and it is also recommended that modifications of program to promote women's childbirth experience should be considered.

Purpose: This study was done to examine actor and partner effect of dementia knowledge, self-efficacy and depression on dementia preventive behavior in elderly couples. Methods: Participants were 115 couples aged 60 years or over who met eligibility criteria. All measures were self-administered. Data were analyzed using SPSS 18.0 and AMOS 18.0 program. Results: Dementia knowledge in elderly couples showed actor and partner effect on dementia preventive behavior. Self-efficacy in the wife did not have direct effects on dementia preventive behavior, but showed indirect effects through dementia knowledge. Self-efficacy in the husband showed direct effects on dementia preventive behavior and indirect effects through dementia knowledge. Wife's depression had direct actor effect on dementia preventive behavior and indirect effect through self-efficacy and dementia knowledge. Husband's depression did not have direct actor effect on dementia preventive behavior, but indirect effect through self-efficacy and dementia knowledge. Effect size of wives' dementia knowledge, self-efficacy and depression on dementia preventive behavior was larger than that of husbands'. Dementia preventive behavior, dementia knowledge and depression had a mutual effect. Conclusion: Results indicate that to promote dementia preventive activity in elderly couples, programs should be conducted for both of the couple, but focused differently for wife and husband.
