This study uses qualitative data to examine the dynamics and barriers of the delayed family formation phenomenon among the never-married professionals in Korea. The data was drawn from focus groups of 14 never-married professionals aged 28 through 40. The investigation depicts several dimensions of the circumstances of never-married professionals that have not garnered much attention in the literature. This research provides initial evidence of critical influences within the socio-cultural contexts of the participants' dating behaviors as well as the willingness to many. Two different realities, based on gender, were discovered: both male and female voluntarily delayed marriage to pursue their career, education and success. As both reached their career goals, however, male participants experienced a rise in their value as a marriage prospect whereas females experienced decreased value as a marriage prospect. Hence, neo-traditional familism was the dominant value among the participants, but it also functioned as a major barrier to family formation because in the present value system, female professionals, must still struggle with the dual burdens of work and family management.

The study was done to better understand problem behavior in high school students as described in family system theory, which explains the individual’s problem within the family interactions. The purpose of the study 1. To analyze the difference in the parents’ relationship as a couple between the two groups. 2. To analyze the difference in the parent-adolecent relationship between the two groups. 3. To analyze the difference in the family function (cohesion adaptability) between the two groups. The method of the study The staudy subjects consisted of a total of 176 families (528 persons), 109 high school students (End grade) with problem behavior and their parents (problem family group) ,and 69 high school students (same grade) with normal behavior and their parents (normal family group) residing in the Seoul area. Data were gathered from structured, self-reporting qestionaires which included a Couple Relation measurement (95 items) , Parent-Adolescent communication measurement (20 items), Family Cohesion Adaptability Scale (20 items) by DavidH. Olson et al., and a behavior evaluation tool. The results of the study 1. The results as related to the hypothesis were as follows. Hypothesis 1 : “satisfaction within The couple's relationship of the parents of problem family group will be lower than the normal family group was supported significantly(t=3.07, p=.005). Hypothesis 2: “The parent-adolescent relationship of the problem family group will be more negative and problematic than the normal family group” was supported significantly(t=4.06, p=.000). Hypothesis 3: “The family function (cohesion adaptability) of the problem family group will be lower than the normal family group" was supported significantly(t=2.20, p=.022) 2. The results of related analysis were as follows 1) Analysis of a causal relation between the couple’s relationship, the parent-adolescent relationship, family function and adolescent behavior showed that the Above 3 variables influenced adolescent behavior.. In cases where couple’s relation-ship, the parent-adolescent’s relationship, the family function are the better, their adolescent’s behavior is better. 2) Discriminant analysis of the research tool showed The discriminant ability of couple’s relationship tool was 75.57%, the Parent-Adolescent communication tool, 67.05, the family adaptability cohesion tool.67. 61%. In summary, interpersonal relationships in the family subsystems are interactive and their relation influences the behaviors. of adolescents in the family. Therefore, family therapy would be a more effective method than individual therapy, to resolve negative problem for adolscents, and the research tool used in this study are very useful for family system diagnosis and nursing intervention.

This paper presents an effective construction method of adaptive multiple control systems utilizing some knowledge upon the plants. The adaptive multiple control system operates plants un-der widely changing environmental conditions. The adaptive multiple control system is composed of a family of candidate controllers together with a supervisor. The system does not require any identification schemes of environmental conditions. Monitoring outputs of the plant, the supervisor switches from one candidate controller to another, The basic ideas of adaptation are as follows: (1)each candidate controller is prepared for each environmental condition in advance; (2)the supervise. applies a sequence of speculative controls to the plant with candidate controllers just after the start of control or just after the detection of a change in the environmental condition. Each candidate controller can keep the system stable during one-step period of the speculative control and the most appropriate candidate controller for the environmental condition to which the system is exposed can be selected before the last trial of speculative control step comes to an end. We proposed a construction method of adaptive multiple control system without any knowledge of plant dynamics and applied the method to a cart-pole balancing problem and a vehicle anti skid braking system. In real applications, as we can often easily obtain a piece of knowledge upon plant dynamics beforehand, we intend to extend the method such that multiple control systems can be efficiently designed using the knowledge. We apply the new idea to the cart-pole balancing problem with variable length of the pole. The simulation experiments lead us to the conclusion that the new attempt can reduce the manpower to design the candidate controllers for adaptive multiple control systems.

Purpose: This study used a system dynamics methodology to identify correlation and nonlinear feedback structures among factors affecting adolescent cyberbullying victims (CV) in Korea and to construct and verify a simulation model. Methods: Factors affecting CV were identified by reviewing a theoretical background in existing literature and referencing various statistical data. Related variables were identified through content validity verification by an expert group, after which a causal loop diagram (CLD) was constructed based on the variables. A stock-flow diagram (SFD) using Vensim Professional 7.3 was used to establish a CV model. Results: Based on the literature review and expert verification, 22 variables associated with CV were identified and the CLD was prepared. Next, a model was developed by converting the CLD to an SFD. The simulation results showed that the variables such as negative emotions, stress levels, high levels of conflict in schools, parental monitoring, and time spent using new media had the strongest effects on CV. The model's validity was verified using equation check, sensitivity analysis for timestep and simulation with 4 CV adolescent. Conclusion: The system dynamics model constructed in this study can be used to develop intervention strategies in schools that are focused on counseling that can prevent cyberbullying and assist in the victims' recovery by formulating a feedback structure and capturing the dynamic changes observed in CV. To prevent cyberbullying, it is necessary to develop more effective strategies such as prevention education, counseling and treatment that considers factors pertaining to the individual, family, school, and media.
