This study investigated the changes in representation on analogies that elementary science-gifted students generated by using Algodoo program to explain the electric current. After the students were taught about the 'components in circuit and their function' and 'electric current' with teacher centered analogy and PhET program for 4 class hours, they generated analogies to the electric circuit. Then they compared the similarity between generated analogy and target concept and matched it to the target concept. The result revealed that the battery, light bulb, and electric wire were changed according to the change of representations on free electrons. And they generated more proper analogies reflected the target concept when represented the free electrons by the circular particles than the water. From these results, we can say that generating analogy using Algodoo program is the effective education activity to help students understand abstract concept by visualizing it more easily and simply.

This study examined the effectiveness of a social competence program for mentally challenged(IQ 58-74) and/or somewhat autistic 6- and 7-year old children with peer relationship difficulties. The Hierarchical Model of Social Competence by Guralnick(1992) provided the framework of the experimental program. The intervention consisted of 16 sessions: 2 intervention teachers implemented each session for 90 minutes once a week. Target behaviors were to initiate interactions with others, to respond to behaviors of teachers and peers, to participate in group activities, and to express their needs to others with speech. Data on the frequencies of target behaviors, the behavior episodes and parent reports were analyzed. Most of children became to be more sociable, although there were individual differences in the changes in target behaviors.

Crime prevention strategies are introduced to reduce the loss caused by crimes, and Target hardening against domestic burglary attacks is broadly accepted as one of such physical security strategies. In terms of business and home security, target hardening is one of the suite of protective measures that are included in crime prevention through environmental design(CPTED). This can include ensuring all doors and windows are sourced and fitted in such a way that they can resist forcible and surreptitious from the attack of intruder. Target hardening with certified security doors, security windows and secure locks are revealed to be much more effective to deter burglary attacks than other security devices, such as CCTV, lightings and alarms which have largely psychological and indirect impact. A pilot program of target hardening utilizing certified security window and locks was carried out in Ansan city, South Korea in 2016. This study is based on the quasi-experimental design of this program for a residential area. The researchers tried to verify the crime displacement effect of the target hardening program and the diffusion effects of crime prevention benefits by analysing the crime statistics. The evaluation utilized WDQ(Weighted Displacement Quotient) technique to analyze whether the crime displacement occurred, compared the crime statistics of the experimental area with that of buffer zone and controlled areas. The result showed that the target hardening program was significantly effective in crime prevention. The number of burglary in the experimental site with target hardening intervention reduced by 100%, although the areas without the intervention showed reduction in the burglary. The crime displacement was not found at all, and the number of burlary at the buffer zone also reduced significantly.

This paper presents the design and the implementation of CRESTIVE-DX, a concolic testing tool that distribute the concolic testing process over the embedded target system and the host system for efficient test generation of a target embedded program. CRESTIVE-DX conducts the execution of a target program on the target embedded system to consider possible machine-dependent behaviors of a target program execution, and conducts machine-independent parts, such as search-strategy heuristics, constraint solving, on host systems with high-speed computation unit, and coordinates their concurrent executions. CRESTIVE-DX is implemented by extending an existing concolic testing tool for C programs CREST. We conducted experiments with a test bed that consists of an embedded target system in the Arm Cortex A54 architecture and host systems in the x86-64 architecture. The results of experiments with Unix utility programs Grep, Busybox Awk, and Busybox Ed show that test input generation of CRESTIVE-DX is 1.59 to 2.64 times faster than that of CREST.

The purpose of this study was to suggest directions for developing a Health Promotion Program for the elderly in Korea for the future. For this, twenty previously developed & implemented health promotion programs were reviewed and analyzed in terms of target population of the program, components of the program, measurement variables for effects of program, the effects of the program. The results were as follows. 1. Most of the target populations were older adults living independently in the community. 2. Components of the program were health education, health assessment and counseling and exercise program. - Health education was done in most of programs. The topics of health education that were often included in the programs were life style changes, medical knowledge, independent living, the concept of health promotion and changes related to aging. - In health assessment and counseling, health professionals discovered their health problems through health assessment or health risk appraisal. Then they developed health recommendations on each health problem and encouraged the elderly to implement the recommendations. 3. Variables measuring the direct effects of the program were health behavior, knowledge, attitude, skill, use of medical/health reference book. Variables measuring the indirect effects, biometric outcome, health status, functional status, medical service utilization, medical cost and wellbeing. 4. The analysis showed that health education was effective for changing health behaviors, improving knowledge, skill and attitude in the elderly. Those results were suggested to be used as guidelines for developing a health promotion program for the elderly in Korea for the future.

Objective: The purpose of this study was to contribute to the prevention of occupational diseases through the development of an automatic analysis program for evaluating workers' exposure to hazardous chemical substances. Methods: The authors selected chemical substances that caused occupational disease in Korea and chemical substances that are frequently used in industrial sites as target substances for a GC-MS automatic analysis program. The target substances are organic compounds which can be measured by a passive sampler. The automatic analysis program was studied using various raw data obtained from GC-MS analysis for the target substances. Results: A total of 48 organic compounds that can be measured with a passive sampler were selected as target substances for the GC-MS automatic analysis program. The selected compounds included substances that caused occupational disease, substances related to C1 and D1 in special health examinations, and substances for which work environment measurements have been frequently conducted. The GC-MS automatic analysis program was developed by combining information mainly on retention time and mass spectrum. The GC-MS automatic analysis program is designed to analyze unknown samples by comparing the mass spectrum and retention time of the samples to those of reference materials. To evaluate the stability of the program, samples at about the 30-50% level of OELs were prepared and analyzed with the GC-MS automatic analysis program, resulting in stable results for all 48 organic compounds. Conclusion: An automatic analysis program for a total of 48 organic compounds was developed using a GC-MS system that can analyze organic compounds. Unknown samples that contain the 48 organic compounds can be automatically analyzed by the developed program. It is anticipated that it can contribute to the prevention of occupational diseases through an GC-MS automatic analysis program that can quickly provide workers with information on exposure to chemical substances.

The acoustic target strength (TS) is one of the most important parameters for a submarine's stealth design. Because modem submarines are larger than their predecessors, TS must be managed at each design stage in order to reduce it. To predict the TS of a submarine, TASTRAN R1 was developed based on a Kirchhoff approximation in a high-frequency range. This program can present TS values that include multi-bounce effect in the exterior and interior of the structure by combining geometric optics (GO) and physical optics (PO) methods, anechoic coating effect by using the reflection coefficient, and response time pattern for a detected target. In this paper, TS calculations for a submarine model with the above effects are simulated by using this developed program, and the TS results are discussed.

The Government bean implementing the National Cancer Screening Program(NCSP) in 1999 and expanded its target population and target cancers. The target cancers of NCSP since 2004 are the five most common cancers in Korea: stomachm liver colorectal, breast, cervical cancer. One goal of the NCSP in 2005 is to include in its target population up to lower 50% of premiu of National Health Insurance. The Government and National Cancer Center have bee developing the protocol for the NCSP with associated related academic societies Health Centers operate the NCSP with National Health Insurance Cooperation. The Particioants of NCSP in 2004 are 1.34million, 14% of target population and the detection rate 2004 is 0.07%. NCSP has three challenges. Firstly, NCSP improves the participant rate through educating cancer screening increasing the access of screening(e.g. mobile screening unit), and increasing reimbursement fee Secondly NCSP assesses the quality of screening with related academic societies and implement the intervention for quality improvement. Thirdly, NCSP continues to increase the cost-effectiveness through modification of target population, screening interval, method, and information system.
