Purpose: The purpose of this study was to construct and test a structural equation model for Diabetes self-management (DSM) behavior and Quality of life (QoL) in older adults with diabetes who use Citizen Health Promotion Centers. The theory used this study was a combination of the Information-Motivation-Behavioral Model (IMB) and Self-Determination Theory (SDT) to reflect autonomous characteristics of participants. Methods: Data were collected from April 20 to August 31, 2015 using a self-report questionnaire. The sample was 205 patients with type 2 Diabetes who regularly visited a Citizen Health Promotion Center. SPSS 22.0 and AMOS 22.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factor affecting the participants' DSM behavior and QoL. Results: The supported hypotheses were as follows; 1) The variable that had a direct effect on QoL was health behavior adherence (${\gamma}=.55$, p=.007). 2) The variables that had a direct effect on DSM behavior were DSM information (${\gamma}=.15$, p=.023), DSM confidence (${\gamma}=.25$, p<.001), and autonomous motivation (${\gamma}=.13$, p=.048). 3) The variable that had a direct effect on DSM confidence was autonomy support (${\gamma}=.33$, p<.001). Conclusion: The major findings of this study are that supporting patient's autonomous motivation is an influential predictor for adherence to DSM behavior, and integrative intervention strategies which include knowledge, experience and psychosocial support are essential for older adults with diabetes to continue DSM behavior and improve QoL.

In case that pile cap is in direct contact with underlying soil, the bearing mechanism for pile groups, including direct bearing effect of cap and its induced influence on pile-soil-cap interaction, should be properly considered. In this paper, the effects of pile caps on behaviors of pile groups in sandy soils were investigated by model tests, which consist of tests on 3 by 3 pile groups with/without contact on subsoil, single pile with/without contact and cap as a shallow foundation. Also, the influences of pile spacing in group piles on contact effects were investigated. The test results showed that the load carrying capacity of pile cap was large enough not to be ignored. However, the interaction effects due to contact between cap and subsoils were not revealed obviously in working load range. And in the design of pile groups, the bearing effect of pile cap when contacted with subsoils, can be reflected by simply summing up load settlement behaviors of each cap and group piles without contact.

The main purpose of this study was to investigate the relationship between financial management behavior and subjective level of consumption of rural households. In this study, financial management behavior was defined to include 'budgeting' and 'expenditure management'. Data were collected from the 215 rural households in 13 different provinces of Chungnam, and 203 households were used for the analysis. Frequency distribution, means, and path analysis were employed for the statistical analysis. Major findings were as follows. Budgeting behavior had a significant positive effect on rural households' subjective level of consumption, while expenditure management behavior didn't have any significant effect. This implies that active and systematic financial management behavior such as budgeting is more effective than relatively passive financial management behavior like expenditure management on the enhancement of economic well-being of rural households. Age, education, and number of non-farm earners had indirect effects on the subjective level of consumption through budgeting behavior. Income stability had a direct effect and income had both direct and indirect effects on the subjective level of consumption.

In this paper, we investigated the factors affecting the intention to use smartphone banking with a research model based on the Technology Acceptance Model (TAM) extended to include security risk, trust, and self-efficacy. With analysis after controlling factors such as age, gender, and previous experience of smartphone banking that may have effects, we conclude that perceived usefulness, perceived ease of use, security risk, and trust have direct effect on the intention to use smartphone banking, and self-efficacy has indirect effect on the intention to use through mediation of perceived ease of use. We performed a study to check the validity of TAM in the context of smartphone banking, and confirmed that perceived ease of use has both direct and indirect effect on the intention to use.

The effect of the intake flow on the spray structure of a high pressure 11-hole fuel injector were examined in a single cylinder optical direct injection spark ignition (DISI) engine. The effects of injection timing and in-cylinder charge motion were investigated using the 2-dimensional Mie scattering technique. It was confirmed that in the homogeneous charge mode, the in-cylinder swirl charge motion played a major role in the fuel spray distribution during the induction stroke rather than the tumble flow. But, in the stratified charge mode, the effect of the in-cylinder charge was not so large that the injected spray pattern was nearly maintained and the increase of in-cylinder pressure by the upward moving piston reduced the fuel spray penetration.

New elderly consumer market composed of consumers 50 years or older has both resemblance and difference with younger fashion market. This study aimed to examine the effect of socio-demographic and psychological factors on fashion innovativeness and monthly spending on clothing of new aged elderly consumers with the moderating role of materialism. The study found that socio-demographic factors tended to have direct effects on clothing spending, while psychographic factors have both direct effect and indirect effect through fashion innovativeness. The mediating role of fashion innovativeness in predicting clothing spending was found to be moderated by materialism of new elderly consumers. Marketing implications and limitations were discussed.

The purpose of this study was to investigate the effect of couples' self-differentiation by marital satisfaction according to couple's gender. The participants of the present study were 728 couples who lived in Chonbuk province. The data were collected by self-administered questionnaire method. Self-differentiation scale was consisted of such factors as emotional reactivity, I-position, emotional cut-off and fusion with others. The results of this research were as follows: First, there was significant difference in the level of total self-differentiation between husbands and wives. Second, there was significant difference in the levels of marital conflict and of marital satisfaction to levels of self differentiation. Third, self differentiation in both husbands and wives had an direct effect on marital satisfaction and stability through marital conflict. Fourth, marital conflict in both husbands and wives had a direct effect on marital satisfaction.

In this paper, we present a novel approach to analyze the throughput of direct-sequence spread spectrum multiple access (DS/SSMA) unslotted ALOHA system. In the unslotted system, the departure rate of interfering transmissions is proportional to the number of current interferers that can be regarded as the system state. In order to model this state-dependency, we introduce a two-dimensional state transition model that describes the state transition of the system. This model provides a more rigorous analysis tool for the DS/SSMA unslotted ALOHA systems with both fixed and variable packet lengths. Numerical results reveal that this analysis yields an accurate system performance that coincides with the simulation results. Throughout the analysis we have discovered that the state-dependency of the departure rate causes interference averaging effect in the unslotted system and that this effect yields a higher throughput for the unslotted system than for the slotted system when supported by a strong channel coding.

Purpose: This study aimed to develop a model that describes factors influencing meaning in life among the middle-aged in Korea, and to verify the appropriateness of the model. Methods: The participants were 424 middle-aged residents of Daegu city, Korea. The data were collected through a structured questionnaire from October 4 to 30, 2010 and analyzed using SPSS/WIN 18.0 and LISREL 8.30. Results: Reported life satisfaction and religion had observed to have a significant direct effect on meaning in life, and coping behavior and self-esteem exhibited significant direct and indirect effect. In addition, depression, economic status, and life stress had a significant indirect effect on meaning in life. Life satisfaction was the most influential factor, and all of these variables explained 53% of the variances in meaning in life among the middle-aged. Conclusion: The findings from this study add to the body of knowledge about the factors that influence meaning in life and need further study. The variables in this study could be used as part of the assessment of the middle-aged.
