Purpose: The purpose of this study was to develop an antepartum-postpartum breast-feeding program titled "Breastfeeding Empowerment Program" and to measure the effects of this program on breast-feeding empowerment and the rate of exclusive breast-feeding. Methods: The study design was a nonequivalent control group design with repeated measures. Results: The scores for breast-feeding empowerment of the experimental group (EG) were higher than those of the control group (CG) at week 1, 4, 8, 12. The rates for exclusive breast-feeding of the experimental group were also higher than those of the control group: 86.4% in the EG and 40.9% in the CG at week 1; 100% vs 42.9% at week 4; 86.4% vs 38.1% at week 8; 95.5% vs 38.1% at week 12; 94.7% vs 31.6% at 6 months; 89.5% vs 26.3% at 12 months. Conclusion: The study provided evidence that raising consciousness and strengthening mother's will and skills for exclusive breast-feeding helps them to achieve successful breast-feeding by themselves. In addition mothers need to be empowered to breastfeed starting before delivery and continuing after delivery. This approach could make long-term exclusive breast-feeding successful.

Purpose: The purpose of this study was to investigate the effects of a breastfeeding support program (BSP) on the prevalence of exclusive breastfeeding and growth in late-preterm infants. Methods: A quasi-experimental study was conducted. The participants were 40 late preterm infants (LPIs), of whom 20 were assigned to the experimental group and 20 to the control group. For the mothers in the experimental group, a BSP was provided prior to the LPIs' discharge and reinforced once a week for 4 weeks. Information on the feeding type was collected by observation and the LPIs' body weight was measured. Results: There were significant differences in feeding type by group and time. Exclusive breastfeeding was 5.18 times more common in the experimental group than in the control group (odds ratio=5.18, 95% confidence interval=1.11~16.70). However, weekly weight gain did not show a significant relationship with group and time (F=0.40, p=.712). Conclusion: The BSP was helpful for increasing the rate of exclusive breastfeeding in LPIs. Furthermore, the LPIs in the experimental group, which had a higher likelihood of being exclusively breastfed, showed an equivalent amount of weight gain as the LPIs in the control group, in which infants were more likely to be formula-fed.

The purpose of the study is to examine various conditions, which are recognized by teachers in the allocation of subject-specialized teachers at elementary schools, into five types of conflicts, in order to offer implications for the operation and allocation of the subject exclusive system henceforth. The study, therefore, categorized the actual allocation process experienced by subject-specialized teachers at elementary schools into five aspects the first is, understanding of students, the second, the ability to teach exclusive subjects, the third, a relationship with students, the fourth, workplace environment at schools, and the fifth, the continuity of subject specialist teachers. Conditions demonstrated in each category are classified into the types that occurred by individual and mutual roles demonstrated through in-depth, where keywords are selected by aspects to suggest conflict conditions. In order to operate the subject exclusive system more efficiently and to boost the effects of positive education, the workplace environment at schools need to be improved urgently, including a variety of training, program development, and financial support. The most vital requirement is to prepare groundwork through mutual understanding and collection of extensive opinions from field teachers based on a consensus that a school is an educational community. The study anticipates that the result could provide a foundation for the preparation of qualitative improvement and development measures for the subject exclusive system at elementary schools.

광역 조건식의 계산은 분산 프로그램의 수행을 테스트 또는 디버깅하기 위한 방법으로 활 발히 연구되고 있다. 이제까지 주로 연구된 광역조건식은 AND 또는 OR 광역 조건식 등이 있는데, 특히 AND 광역 조건식은 분산 프로그램의 동시적 조건을 표현하는데 유용하여 효율적인 검색 알고리즘이 활발히 연구되었다. 분산프로그램의 수행오류로서 공유자원의 배타적 접근조건은 가장 중요하고 일반적인 경우라 할 수 있다. 본 논문에서는 XOR 연산을 이용하여 공유자원 프로그램의 오류 검색을 위한 광역조건식을 기술하는 방식에 대해 제안하였다. XOR 연산을 이용한 광역 조건식은 연산자 중 많아야 하나의 지역조건식만이 참일 때 전체 조건식이 참이 되는데 이러한 성질은 여러 프로세스 중 한번에 하나만이 공유자원에 배타적으로 접근할 수 있는 조건을 표현하는데 매우 유용하다. n 개의 프로세스로 이루어진 분산프로그램에서 한개의 공유자원에 대한 배타적 접근 조건을 기술하기 위해서 AND로 연결된 광역조건식을 이용하면 O(n2)개의 광역 조건식이 필요한데 반해 XOR 연산으로는 하나의 조건식으로 나타낼 수 있다. 더구나 XOR 연산을 이용한 광역조건식은 최근 소개된 겹치는 구간의 개념을 활용하면 매우 간단하게 검색할 수 있다. 본 논문에서는 겹치는 구간을 찾는 검색 알고리즘을 소개하고 증명하였다.Abstract Detecting global predicates is an useful tool for debugging and testing a distributed program. Past research has considered several restricted forms of predicates, including conjunctive or disjunctive form of predicates. Especially, conjunctive predicates have attracted main attention not only because they are useful to describe simultaneous conditions in a distributed program, but also because it is possible to find algorithms to evaluate them within reasonable time bound. Detecting errors in accessing shared resources are the most popular and important constraints of distributed programs. In this paper, we introduced an exclusive OR predicates as a model of global predicates to describe shared resource conditions in distributed programs. An exclusive OR predicate holds only when at most one operand is true, which is useful to describe mutual exclusion conditions of distributed programs where only one process should be allowed to access the shared resource at a time. One exclusive OR predicate is enough to describe mutual exclusion condition of n processes with one shared resource, while it takes O(n2) conjunctive predicates. Moreover, exclusive OR condition is easily detectable using the concept of overlapping intervals introduced by Venkatesan and Dathan. An off-line algorithm for evaluating exclusive OR global predicates is presented with a correctness proof.

The manufacture of an impeller typically requires the 5-axis CNC machining, since the impeller is usually under working conditions such as high speed, high temperature, and high pressure. Thus, this study contributes to development of an exclusive CAM system for effective 5-axis CNC machining of a ruled surface type impeller. In this study, the sampled impeller is made of blades and a body and the blade consists of ruled surfaces between hub curve and shroud curve. In the post processing for 5-axis NC part program, the cutter axis direction vector is the straighten vector on ruled surface. The position of ball center in ball end mill cutter is decided on the interference check between the cutter and body surface of impeller using with the modified z-map method that z-axis is the same of cutter axis direction vector. The exclusive CAM system for an impeller developed in this study was very effective for designs and 50-axis machining of a ruled surface type impeller.

Purpose: A mother's working environment is believed to be a major determinant of exclusive breastfeeding (EBF) practice. We aimed to define the influence of a facility dedicated to breastfeeding and a breastfeeding support program at the workplace on breastfeeding practice. Methods: A cross-sectional study was performed in five workplaces. The inclusion criteria were female workers whose last child was between 6 and 36 months old. Observational data were obtained and a questionnaire was filled out. The World Health Organization definition for EBF was used. Results: Data from 186 subjects (74 office workers and 112 factory workers) were collected. Just over half (52%) of the mothers were between 20 and 46 years old, 75.3% had graduated from high school and university, 12.9% had more than two children and 36.0% owned a house. The prevalence of EBF during the last 6 months was 32.3%. A proper dedicated breastfeeding facility was available for 21.5% of the mothers, but only 7.5% had been in contact with a breastfeeding support program. The presence of a dedicated breastfeeding facility increased EBF practice almost threefold, by an odds ratio (OR) of 2.74 and a 95% confidence interval (CI) of 1.34-5.64 (p<0.05). Knowledge of the breastfeeding support program increased EBF practice by almost six times (OR, 5.93; 95% CI, 1.78-19.79) (p<0.05). Conclusion: Our findings suggest that Governments should make it obligatory for employers to offer a breastfeeding support program and a dedicated breastfeeding facility at the workplace as these simple measures significantly increase EBF.

All steps of the curing process are automatically controlled by preseted program according to stalk positions in flue-cured tobacco. The bulk curing experiment was carried out to evaluate the effect of the basic and modified curing program in curing time schedule of two bulk models in physical properties of cured leaves in a new flue-cured tobacco variety KF 114(Wicotiano tabacum L.). The curing process of KF 114 was prolonged in yellowing and quicker in browning stage than those of NC 82. There was no significant difference in physical properties and chromatic characteristics of the cured leaves between basic and modified program at two bulk models. The ratio of normal leaf color tended to increase and the greenish leaf decreased in the modified curing program of two models, but no difference in the brownish leaf ratio was olserved between two programs.

Background and objective: This study conducted a conjoint analysis on early childhood teachers to find out their preferences in horticultural activities that are used as a means of education in early childhood education. Methods: For the conjoint analysis, five attributes of horticultural activities were selected. Attribute 1 was method of horticultural activities, divided into two levels: exclusive and integrated horticultural activities. Attribute 2 was object of horticultural activities, divided into three levels: fruit crops, vegetable crops, and floricultural crops. Attribute 3 was activity type, divided into three levels: big and small group, free choice, and outdoor play. Attribute 4 was place for horticultural activities, and divided into two levels: indoors and outdoors. Attribute 5 was time for horticultural activities, divided into two levels: 30 minutes and 30-60 minutes. The orthogonal design was used to extract 20 profiles, after which we conducted a survey on 320 early childhood teachers and analyzed the valid responses from 257 teachers. Results: The preference of early childhood teachers showed highest importance in object (29.1%), followed by activity type (23.2%), activity method (17.4%), time (16.1%), and place (14.2%) (Pearson's R = .591, p = .008). By level of each attribute, the importance was high in exclusive horticultural activities for activity method, big and small group for activity type, vegetable and floricultural crops for object, indoors for place, and 30 minutes for time. Conclusion: The horticultural program preferred by early childhood teachers is comprised of big and small group activities using vegetable and floricultural crops, carried out indoors for 30 minutes as an exclusive class.
