  • In this paper, an inspection system has been developed where pneumatic instruments are used to stretch the film using compressed air, thus the curl problem can be overcome. When the pneumatic system is applied, a line scan camera should be used instead of an area camera because the COF surface makes an arc by the air pressure. The distance between the COF and the inspection camera should be kept constant to get a clear image, thus the position of COF is to be monitored on real-time. An operating software has been also developed which is switching on/off the pneumatic system, determining the COF position using a camera vision, displaying the contour of the COF side view, sending self-diagnosis result and etc. The developed system has been examined using the actual roll of COF, which convince that the system can be an effective device to inspect the COF rolls in process.

  • This study was conducted to develop self-repairing ability for concrete so that inspection could be available even in the event of minute cracks, for more economic concrete structure maintenance and longevity. This is a basic attempt to develop self-repairing concrete using the biochemical reaction of bacteria through an innovative method. In this study, the characteristics and problems posed by self-repairing concrete as proposed in international scientific journals were examined, and the potential of new concrete reformation and performance improvement using bio-mineralization was explored. Bio-mineralization, which is an action of creating bio-minerals using an organism, was proposed. A new concept of bacteria such as bacillus pasteurii using bio-mineralization that precipitates calcium carbonate, as well as the possibility of mechanical performance and durability of concrete and repair of cracks, was introduced. Directions for further study through basic experiments and developmental feasibility of self-repairing concrete were also presented.

  • In this sutdy, a new class ACA(Anisotropic Conductive Adhesive) with low-melting-point alloy(LMPA) and self-organized interconnection method were developed. This developed self-organized interconnection method are achieved by the flow, melting, coalescence and wetting characteristics of the LMPA fillers in ACA. In order to observe self-interconnection characteristic, the QFP($14{\times}14{\times}2.7mm$ size and 1mm lead pitch) was used. Thermal characteristic of the ACA and temperature-dependant viscosity characteristics of the polymer were observed by differential scanning calorimetry(DSC) and torsional parallel rheometer, respectively. A electrical and mechanical characteristics of QFP bonding were measured using multimeter and pull tester, respectively. Wetting and coalescence characteristics of LMPA filler particles and morphology of conduction path were observed by microfocus X-ray inspection systems and cross-sectional optical microscope. As a result, the developed self-organized interconnection method has a good electrical characteristic($2.41m{\Omega}$) and bonding strength(17.19N) by metallurgical interconnection of molten solder particles in ACA.

  • Objectives: This study was conducted to explore the effect of the sexuality education in elementary school in regard to students' knowledge, attitude, and role identity about sex. Methods: We classified students into experimental group and control group, and carries out the planned sexuality education to the experimental group. Study subjects were 200 students in one elementary school. Experimental group compromised of 50 boys and 50 girls, and control group so did. Self-administered questionnaire was used for preliminary investigation from 15th to 16th, October in 2009. The post investigation was carried out to the control group 5 weeks later, and to the experimental group for 5 weeks (total 10 hours, 2hours each a week) after the sexuality education from 23th of November to 25th of November, 2009. Results: Experimental group had significantly higher post-inspection scores of sex-related knowledge, attitude against sex, sex-related role identity (excluding leadership dominance, concession, cheerfulness gentleness and sympathy shyness) than pre-inspection scores. Conversely, control group had insignificantly higher post-inspection scores (excluding all scores of sex-related knowledge and scores of atttitude against sex including psychological development and pregnancy). Conclusions: Our study suggested that sexuality education in elementary school have an impact on forming knowledge, attitude, and role identity regarding the sex.

  • We analyze the HACCP Prerequisites of National Veterinary Research and Quarantine Service (NVRQS), Korea Food and Drug Administration(KFDA), and US Food Safety and Inspection Service (FSIS) and recommend contents and ranges to be complemented and used for the preparation of guidelines. We used the HACCP Notice of the Processing Livestock Act, the HACCP Application Manual for Livestock Processing Plants, the HACCP Notice of the Food Sanitation Act, US GPO 9 CFR and 21 CFR, US FSIS Directive 11,000.1, and HACCP-based Inspection reference guide of Consumer Services, North Carolina Department of Agriculture. The Prerequisites of NVRQS and KFDA are composed of 66 and 84 items respectively, without detailed guidelines for their application. This may decisively affect the application in the field and the evaluation activities. Water supplies, washing and disinfection monitoring tools, and examining and correcting plan are required to be improved. If the standards of compliance of each Prerequisite item as well as performance guidelines are given, the application and evaluation will be performed more effectively. The evaluation items should be associated with Prerequisite operations such as non-compliance complement, self-evaluation, and record keeping. Hazards found during official inspection should be promptly controlled not to contaminate the work places and processing items. As the HACCP is expected to spread from farms to tables, the standardized Prerequisite program among the official governments should be prepared.

  • To survive in the trend of the fourth industrial revolution, companies are putting a lot of attention and effort into personalization services using the latest technologies such as big data, artificial intelligence and the Internet of Things, while entrusting third parties to handle personal information on the grounds of work efficiency, expertise and cost reduction. In such an environment, consignors need to check trustees on a more effective and reasonable basis to ensure personal information safety for trustees. This study used AHP techniques to derive the importance and priority of each item of "Personal Information Safety Assurance Measures" for financial companies and trustees, and objectively compared and analyzed differences in perceptions of importance between financial institutions and trustees. Based on this, the company recognizes the difference between self-inspection of financial institutions and inspection of trustees and presents policy grounds and implications for applying differentiated inspection standards that reflect the weights appropriate for the purpose.

  • Under the Act amended on August 4, 2011, a special fire-fighting investigation was conducted by the relevant person (owner, manager, oil refineries), and the responsibility was also given to the relevant person. Instead of directly entering all existing fire-fighting targets and investigating the maintenance and management status of fire-fighting facilities, the fire-fighting agency selects and visits some targets every year, checks the maintenance and management status of fire-fighting facilities, corrects them, and imposes fines, etc. Reasons for the introduction of the system were the establishment of a private autonomous correction system by strengthening the responsibility of officials, lack of firefighting professionals, possible corruption due to frequent public contact, and responsibility of fire agencies. However, many problems arose even after the introduction of a special fire investigation system. A special fire investigation, one of the fire safety systems, checks whether related public officials and especially fire officials are properly installed, maintained and managed in accordance with relevant laws. Special firefighting investigations were introduced as firefighting inspections at the time the firefighting law was enacted in 1958, and have undergone a revised process more than 30 times until recently. Firefighting Facility Installation, Maintenance and Safety Management Act", the existing firefighting inspection was changed to a special firefighting investigation and accepted. At the time of enactment of the Fire Service Act in 1958, a special firefighting investigation was introduced as a firefighting inspection, and until recently, more than 30 revisions have been made. In 2003, as the existing fire fighting system was divided into four laws, it was approved by changing the existing fire fighting inspection to a special fire fighting investigation in the "Fire Fighting Facility Installation, Maintenance and Safety Management Act".

  • To provide data necessary for effectively applying the HACCP system by understanding the current application condition of HACCP system and satisfaction level of the dietician in elementary schools, a mail-in survey was conducted on dieticians serving for 227 elementary schools applying HACCP system in Kyungsangbuk-Do since November 1, 2001 to December 20, 2001. 83.5% of the subjected schools were conducting more than 50% of HACCP cooking process management, and the level of cooking process management displayed significant relevance according to the number of dieticians serving the school meals. The area that was not well conducted in the field of HACCP system was proven to be water examination(94.0%), inspection on self-sanitation of cooks prior to cooking(90.6%), and maintenance of dry kitchen floor(l4.8%). The reason why the above areas are not well conducted was because of lack of time due to over workloads. Subjective dieticians had pointed out improvement of sanitary concept(58.1%) and improvement of self-sanitation (28.8%) as benefits of applying HACCP. 21.2% of the subjective dieticians were satisfied with application HACCP and 35.2% were dissatisfied with applying HACCP. In case of which the duration of applying the HACCP was longer than one year and in case of higher rate of HACCP cooking process management and longer work experience of the dieticians, the level of satisfaction was proven to be significantly higher. The most difficult things to follow in important management categories according to the features of dietitian work and work experience were food distribution of CCP7 step and maintenance of optimum temperature(70.7%). Subjective dieticians had pointed out insufficient facility or environment and lack of inspection equipments in order regarding problems of applying HACCP. Also in the level of necessity of improvement categories in applying HACCP, dieticians had replied that facility and equipment improvement was mostly needed. Due to the induction of HACCP system in school meals, comparatively well cooking process management is being conducted, and I believe it could contribute in securing safety and quality improvement of school meal by improving the sanitation concept of the dieticians. However, the satisfaction level of dieticians are rather low and there are many difficulties in maintaining optimum temperature in the process of food distribution and transportation process. Also, lack of facilities and environment, lack of inspection equipments and etc are pointed out as problems of inducing HACCP. Thus, to settle HACCP system, it is believed that brave investment must be preceded.

  • Although everyone grows old, perception about the aging process and aging as measured physiologically vary widely. Perecptions of aging have psychologically influence on physical aging. This study was to examine the relationships between, self-concept, perception of aging, and physical aging in the elderly and to contribute to the theory development which may direct nursing intervention to promote well-being of the aged. Subjects were 70 women residents of a nursing home for the elderly in Seoul. Data collection was done from May 15 to June 15, 1988 using interview schedules and mechanical instruments. The instruments were selected items from the Health Self Concept Scale developed by Jacox and Stewart for self concept, and Secord and Jourad's Body Cathexis Scale and Osgood's Semantic Differential Scale for perception of aging. Physical aging was measured by mechanical instruments, inspection, questions, and palpation. The data were analysed for mean, 1-test, ANOVA, and Pearson Correlation Coefficient using an S.P.S.S computerized program. The results of the analysis were as follows. 1. The mean level of self concept for the subject group was 16.97(SD=$\pm$6.17)in a range from 6-30. The mean level of perception of aging was 39.6. (SD=$\pm$6.51) in a range from 13-65. The mean level of physical aging was 14.09(SD=$\pm$2.05)in a range from 8-40. 2. Relationships among self - concept, perception of aging, and physical aging. 1) There was a positive relationship between self-concept and perception of aging(r=0.4461, p=0.000). 2) There was a negative relationship between physical aging and perception of aging(r=-0.2975, p=0.006). 3) There was a tendancy toward a negative relationship between physical aging and self -concept, but not a significant relationship (r=-0.1033, p=0.197). 3. 1) No general charcteristic variables were related to self concept. 2) The general characteristic variable related to the level of perception of aging was religion (t=4. 17, p=0.001). 3) The general characteristic variable related to the level of physical aging was age (F=12.008, p=0.000). There was a significant relationship between self - cencept and perception of aging, and between physical aging and perception of aging. Therefore nursing intervention should focus on promoting a positive perception of aging and strengthening self- concept during the physical aging process.
