The condition of nutrition during infancy will greatly affect infants' physical, emotional growth, especially breast feeding is important in their growth and development, and emotional stability, too. Despite such advantages of breast-feeding, its rate has continued to fall year after year in Korea : the 95% rate in 1960's has fallen to 25.4% in 1990. It is known that such a downfall of breast-feeding rate is associated with various factors. The purpose of the study is to examine mother's and nurses' in nursery perception of the impediment factors of breast-feeding : to compare those between of breast-feeding : to compare those between two groups : to provide fundamental data for developing strategies for increasing breast-feeding. The subjects were 45 new mothers from one hospital and the same number of nurses sampled from 3 university hospitals, in Seoul. The data were collected for 11 days from April 12 to April 23, 1994 and a questionnaire was developed based on the interview with 14 nurses and 10 mothers and the literature reviews. Liker's Five-Point Scale was used as measurement. The Data were analyzed using SPSS / PC and descriptive statistics, t-test, ANOVA. The results of study are as follows : 1) Most new mothers get the information about breast-feeding from their mothers, books or newspaper, and relatives in rank than professionals(nurses or doctors). 2) The impediment factors the breast-feeding are categorized as mothers, hospital system, medical personnels and social factors. The most frequently mentioned impediment factors from mothers are 'Difficulty by operational wounds'(3.13), 'Lack of will for breast-feeding'(3.47), 'Insufficient rest and sleep'(3.52) and 'Opposition from husband or his family members'(4.77)in rank. On the other hand those factors from nurses are 'Inadequate nipple condition'(2.37), 'Decreasing milk secretion given medicine after operation'(2.63), 'Mothers knowledge deficit by poorly prepared education'(2.79) and 'Mothers abhorance of breast-feeing'(3.87) in rank. 3) As for the hospital system, the highly perceived impediment factors by mothers are 'Seperation of baby from mother after birth'(2.78), 'Lack of space for breast-feeding in the hospital'(2.93), 'Lack of facility for informing the time for breast-feeding'(3.18) and 'Because of babys' preference artificial nipple by being accustomed to it in hospital(3.97), in rank. Meanwhile, those from nurses are "Seperation of baby from mother after birth",(1.92), "Inconsistency between hospital's nursing time and mother's breast secretion time" scretion time(2.97), "Lack of space for breast-feeding in the hospital"(3.39), and "Lack of facility for informing the time for breast-feeding"(3.74) 4) As for the medical personnels, the highestly perceived Impediment factor from mothers in "Lack of professional nurses for breast-feeding"(2.96), and the lowestly perceived one is "Doctors' reluctance"(4.75). Nurses perceived same as mothers, too. 5) As for the social factors, the highestly perceived impediment factor by mothers and nurses is "Inconvience of social activities"(2.83) and the lowestly ones are "The sense of self-sacrifice"(4.22) by mothers, and "The sense of old fashioned"(4.13) by nurses. 6) The difference of the perception of impediment factors between mothers and nurses is statistically significant only in mother factor.

This study evaluates the impact of an information security policy sanction, a perceived threat, and the perception of the information security climate on a compliance behavioral intention. The research method was structured with a cross-sectional study design for the prospect and goal orientation. The variables used in the analysis are information security policy sanction, perceived threat, perception of information security climate, and compliance behavioral intention. Progress in this research consists of measuring the prospect and goal orientation, and then measuring the four variables. As a result, the prospect had a significant effect on the perception of the information security climate, and it was found that the influence of the gain-based condition was greater than the loss-based condition. Goal orientation had a significant effect on the information security policy sanction, the perceived threat, and the compliance behavioral intention, and the influence of the development-based condition was greater than the stability-based condition. Both prospect and goal orientation had an interactive effect on the compliance behavioral intention. The exploration model was verified as a mediation model. In addition, the discussion includes the appropriate implications for information security based on these research results.

In this study, self-supporting roofing elements especially convenient for large-span structures such as stadium, airport terminal, mall, coliseum, etc. were examined with respect to critical buckling load. These elements were assumed as laminated composite plates and, variation of free-edge forms, cutout types and lamination configurations were used as design parameters. Based on the architectural feature and structural requirements, the effects of curvilinear free-edge form on critical buckling load were focused on in this research. Within this scope, 14 types of lamination configuration were specified according to various orientation angle, number and thickness of plies with a constant value of total plate thickness. Besides that, 6 different types of cutout and 3 different free-edge forms were determined. By combining all these parameters 294 different critical buckling load analyses were performed by using ANSYS Mechanical software based on finite element method. Effects of those parameters on critical buckling load were evaluated referring to the obtained results. According to the results presented here, it may be concluded that lamination conditions have more significant influence on the critical buckling load values than the other parameters. On the other hand, it is perceived that curvilinear free-edge forms explicitly undergo changings depending on lamination conditions. For future work, existence of delamination might be considered and progression of the defect could be investigated by using non-linear analysis.

Users quite often experience volatile channel conditions which negatively influence multimedia transmission. HTTP adaptive streaming has emerged as a new promising technology where the video quality can be adjusted to variable network conditions. Nevertheless, the new technology does not remain without drawbacks. As it has been observed, multiple video players sharing the same network link have often problems with achieving good efficiency and stability of play-out due to a mutual interference and competition among video players. Our investigation indicates that there may be another cause for under-performance of the streamed video. In an emulated environment, we implemented three algorithms of adaptive video play-out based on bandwidth or buffer assessment. As we show, traffic generated by players employing the same or similar play-out strategies is positively correlated and synchronised (clustered), whereas traffic originated from different play-out strategies shows negative or no correlations. However, when some of the parameters of the play-out strategies are randomised, the correlation and synchronisation diminish what has a positive impact on the smoothness of the traffic and on the video quality perceived by end users. Our research shows that non-correlated traffic flows generated by play-out strategies improve efficiency and stability of streamed adaptive video.

This study attempted to examine the changing patterns of marital love constructs among married men and women in Korea. It is based on our prior research that showed each of the 3 dimensions of marital love(intimacy, passion, and commitment derived from Stermberg’s Triangular Theory of Love) shaped U pattern as the marriage continued. We analyzed 1687 respondents’answers by principal axis factoring with contextual point of view including individual, familial, and socio-cultural development. The results are as follows. First, the love constructs of Korean men and women in their marriage show different qualitative patterns as the marriage continued. Second, intimacy is the most powerful indicator of love, coming out the first factor in all the stages of marital relationships. Third we can see marital stability from the locus of commitment with other components of love and it could be apply to marital educational program for promoting marital stability. Forth, passion is found separated behavioral from perceived dimension except the first marital stage. As conclusion, it need to analyze with family life cycle. birth and marriage cohort groups for examining closely the causes of this qualitative changes in marital relationships.

A standard on talker echo for ISDN telophone, mainly consisting of those on sending and receiving loudness ratings and terminal coupling loss(TCL), is necessary. Accordingly, if sending and receiving loudness ratings are pre-determined, we need a standard on TCL providing echo-free telephone communications to telephone users, and the standard can be classified into that weighted TCL($TCL_w$) and that on stability loss. In this paper, in order to make a national standard on TCL, based on users' perceived quality on a talker echo, we conducted user opinion tests on talker echo. From the results of correlation between echo and user opinion on quality and measurement on TCL of telephones, we proposed the standard as follows; we must preserve TCL_w of at least 40dB and stability loss of at least 10dB when overall loudness rating for ISDN telephone, sum of sending and receiving loudness ratings, is normalized to 10dB.

This study aimed to identify elementary school teachers' perceptions of various aspects of physical environments of a classroom. For the purpose, a survey questionnaire was administered to 982 classroom teachers(female 82.2%) working at 67 elementary schools(Seoul 55%) located in Seoul and Busan. According to the analyses of the survey data, 50.8% of the respondent teachers suggested 20-25 as an optimum class size. Also, 57% of the teachers were positive about the current size of a classroom($67.5m^2$), but evaluations of a classroom size were divided between the teachers who had more and less than 30 students in class. Furthermore, three factors, labelled as 'uniqueness', 'residential stability' and 'visually pleasing', were extracted from a factor analysis of the Semantic Differential Scale consisting of 24 adjectives evaluating a classroom environment. Teachers from Busan tended to rate higher in the uniqueness domain while female teachers scored higher in the domain of residential stability, respectively, compared to their counterparts. Overall, the teachers perceived their classrooms having no particular characteristics, but rated highly in terms of stability. In addition, it was found out that the teachers' requests for the improvement of a classroom environment were not so much as the increased size of a classroom as a reduced class size as well as educational facilities that are corresponding to a variety of instructional methods. In summary, this study confirmed that elementary school teachers' perceptions of a classroom environment varied according to such factors as sex, teaching career, grade of their concerned class, and class size.

In this study, a research model was established and analyzed in order to examine how the characteristics of organizational culture affect the innovation behavior of employees. This study divided the characteristics of organizational culture into development, stability, and rationality as sub-factors, and conducted a study on the relationship between characteristics of organizational culture and innovation behavior. This study also attempted to confirm whether creative efficacy mediates between the characteristics of organizational culture and innovation behavior. To this end, the data collection was targeted to 80 members of the organization in the company, and the SPSS and PLS programs were used to analyze the collected data. As a result of hypothesis testing, only stability among the characteristics of organizational culture had a significant direct effect on innovation behavior. These results can be interpreted as meaningful results in a study between the characteristics of organizational culture and the innovation behavior of employees. In addition, creative efficacy was found to significantly mediate the influence of organizational cultural characteristics (development, stability, and rationality) on employees' innovation behavior. We suggest that companies should focus on forming an organizational culture in terms of internal stability perceived by employees, and lead employees' innovation behavior to create organizational performance. We propose that companies should create an organizational culture so that the characteristics of the organizational culture (development, stability, rationality) increase the creative efficacy of the employees and lead to the innovation behavior of the employees.

This study verified the effect of occupational value, as felt by new employees working in the food service industry, on turnover intent and also the moderating effect of perceived organizational support between occupational value and turnover intent. The analysis drew out the following results. First, the study verified that, among inherent values, only social commitment had a positive(+) direction of influence on turnover intent, and second, among extrinsic values, only face-saving and stability seeking had a positive(+) direction of influence on turnover intent. Third, as a result of verifying the effect of inherent values on turnover intent according to emotional support, the study revealed that turnover intent increased, as the perception of emotional support increased, on condition that the item, value of knowledge seeking, among inherent values, was perceived highly, On the other hand, if the item, relationship-centered, scored highly among inherent values, then the higher the perception of emotional support, the lower the turnover intent. Fourth, as a result of verifying the effect of extrinsic values on turnover intent according to emotional support, the study revealed that turnover intent decreased, as the perception of emotional support increased, on condition that the value of economic priority, among extrinsic values, was perceived highly. On the other hand, if the item, face-saving, scored highly among extrinsic values, then the higher the perception of emotional support, the higher the turnover intent. Fifth, as a result of verifying the differing effect of inherent values according to methodical support, the study revealed that turnover intent increased as the perception of methodical support increased, if the item, knowledge-seeking among inherent values was perceived highly. Sixth, as a result of verifying the differing effect of extrinsic values according to methodical support, the study revealed that turnover intent decreased as the perception of methodical support increased, if the item, economic priority among extrinsic values was perceived highly. On the other hand, if the item, face-saving, among extrinsic values, was perceived highly, the higher the perception of methodical support, the higher the turnover intent.
