The purpose of this study was to develop the Parent Satisfaction Scale(PSS) to measure the various components of satisfaction related to parenting. The subjects were 1210 parents(249 fathers and 961 mothers) selected nation widely from 7 cities and several rural area in Korea. the statistics used for data analysis were Fisher's Exact Test, Cramer's V, factor analysis multiple regression, Cronbach's α,and Pearson's correlation. To begin with eighty of 100-item scale were selected through the item analysis and from that 48 items were abstracted through the multiple regression analysis conducted to reduce the length of the scale. Results of factor analysis indicated that the PSS comprised of five factors: general satisfaction parent-child relationship spouse support parent's role conflict support of children. Reliabilities for the domains ranged from 79 to 91. To determine the construct validity of this instrument the Marital Satisfaction Scale and the Proverb about child rearing were administered. The two creterion measures showed significant relationships with the PSS. The final 48 items scale from the current analysis were considered to be critical steps in the development of this assessment device.

For the development of a short form of the Korean Wechsler Preschool and Primary Scale of Intelligence (K-WPPSI), 360 preschool and primary school children were tested with 4 subtests: Object Assembly, Arithmetic, Block Design, and Comprehension. Transformed scores were derived according to K-WPPSI norms. Interscorer reliability coefficients measured by two independent scorers with the data of 16 children were satisfactory: Comprehension, .92; Arithmetic, .94; Block Design, .97; Object Assembly, .97 Cronbach alpha reliability coefficient for the 4 subtests were very similar to those for the original K-WPPSI, ranging between .71 and .92. Factor analyses revealed 2 factors corresponding to Wechsler's 2 factor theory of intelligence. Discriminant validity was obtained with a Picture-Vocabulary test. Boys performed slightly better than girls on all subtests except for Comprehension. Boys significantly out-performed girls in Arithmetic.

We have development the dimming controller using the ac chopper technique. The ac chopper change the amplitude of the input source voltage with the unchanged its frequency. The conventional dimming controller is operated by controlling voltage phase and is consist of the triac. It has a bad characteristic about a current THD and a power factor. But the dimming controller using the at chopper technique has a low current THD and a good power factor. The developed dimming controller is consist of the MOSFET and the low pass filter. The system is operated by the variation circuit of the input source voltage and the microprocessor.

Regarding the implementation of ROMM project (Rehabilitation, Operation, Maintenance & Management), which is one of overseas development projects, it is very important to diagnose the exact current status of aged thermal power plant. However, when people visit the power plant for the purpose of prediagnosis to implement the ROMM project, most target power plants for diagnosis, in general, are under operation. This can be a big interference factor to diagnose the exact current status of power plants. Therefore, in order to solve such interference factor, based on the 30 years of know-how in the field, the present study has developed a regression curve for a simple life time assessment and the calculation of rehabilitation cost that may be used as a reference relatively for the quantitative diagnosis on the status of a relevant power plant even during the operation of the power plant.

Kawasaki disease (KD) is an acute systemic vasculitis that predominantly affects children, and can result in coronary artery lesions (CAL). A patient with KD who is resistant to treatment with intravenous immunoglobulin (IVIG) has a higher risk of developing CAL. Incomplete KD has increased in prevalence in recent years, and is another risk factor for the development of CAL. Although the pathogenesis of KD remains unclear, there has been increasing evidence for the role of genetic susceptibility to the disease since it was discovered in 1967. We retrospectively reviewed previous genetic research for known susceptibility genes in the pathogenesis of KD, IVIG resistance, and the development of CAL. This review revealed numerous potential susceptibility genes including genetic polymorphisms of ITPKC, CASP3, the transforming growth factor-${\beta}$ signaling pathway, B lymphoid tyrosine kinase, FCGR2A, KCNN2, and other genes, an imbalance of Th17/Treg, and a range of suggested future treatment options. The results of genetic research may improve our understanding of the pathogenesis of KD, and aid in the discovery of new treatment modalities for high-risk patients with KD.

Anthrax is a zoonotic disease caused by Bacillus anthracis, and well recognized as a potential agent for bioterrorism. B. anthracis can be identified by detecting the virulence factors genes located on two plasmids, pXO1 and pXO2. The aim of the present study was to determine the presence of virulence genes in 27 isolates of B. anthracis isolated from clinical and environmental samples. For this purpose, multiplex PCR and DNA probes were designed to detect protective antigen (pag), edema factor (cya), lethal factor (lef), and capsule (cap) genes. Our results indicated that all the isolates contained all the above virulence genes, suggesting that the isolates were virulent. To the best our knowledge, this is the first study about the determination of virulence marker genes in clinical and environmental isolates of B. anthracis using multiplex PCR and DNA probes in India. We suggest that the above methods can be useful in specific identification of virulent B. anthracis in clinical and environmental samples.

A fracture mechanics analysis methodology for stress corrosion cracks (SCCs) existing in the Alloy 600 nozzle weld joint for control rod drive mechanisms (CRDMs) of pressurized water reactor is studied. Effects of weld residual stresses on the sub-critical crack behavior during the reactor operation are investigated by a fracture mechanics analysis, which is combined with the finite element alternating method. It is found that effects f the residual stresses on the stress intensity factor (SIF) and crack growth rate (CGR) are dominant and values of SIF and CGR of cracks in the region of weld joint are increased by a factor of three or more on an average.

This study intends to add a factor to the discussion on the sectoral systems of innovation through Korea's response to the COVID-19 pandemic. The Korean approach is summarized as follows: the first response centers on technology and innovation. These include the development of diagnostic test methods and accurate test kits, first in the world, the use of ICT technology in epidemiological investigations, the technical response in the field, and the competitive edge in the development of medicine and vaccines that were behind the developed countries. The second response is an aggressive effort implemented just after the Chinese announcement, before the domestic outbreak; the third response is the open policy that induces voluntary participation of all subjects and people by opening all information. More important is the leadership at the national level shown in the past Korean experience and most advanced countries. National leadership must be the missing factor.
