This study investigates cognitive sex differences in child and adolescent intelligence as measured by the Korean WISC-Ⅳ. It was hypothesized that there would be no differences attributable to sex in Full Scale IQ (FSIQ), but on various composite score levels. Sex effects were expected to be more pronounced during/after puberty than before. Some of the standardization sample of the Korean WISC-Ⅳ (N=508) was used to assess and evaluate sex differences in test performance across defined age groups (6-9, 10-12, and 13-16 years). At all ages, there were no gender effects in the Full-Scale IQ, Verbal Comprehension Index and Working Memory Index. Age-specific effect with 10-12-year-old children was found in the Perceptual Reasoning Index. In the Processing Speed Index, girls scored higher than boys and this finding was the most prominent in our data. No significant sex-by-age interaction effect was found in Full-Scale IQ, Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index and Processing Speed Index using two-way ANOVA. The limitations of this study and suggested directions for future research were discussed.

Underwater pressure vessel is generally designed and manufactured to resist the water pressure of operating depth. But on account of various unexpected errors in the process of design, manufacture and integration, the pressure vessel can be deformed and water can leak into it at the operating depth. Because there is various equipment taking the roles of control, communication, instrumentation and power source inside the pressure vessel, leakage can occur a fatal influence to the total system. So the leakage detection and notice are very important functions on the underwater pressure vessel. This paper deals with the development of water leakage detector which consists of the conductive adhesive film as a sensing electrode and the ohmmeter as a sensing instrument. To figure out and standardize the shape of water leakage, the underwater pressure vessel having the loose bolts is simulated in the tests at the case of vertical and horizontal position. To find out the effective material of electrode, through the experiment, various kinds of material (aluminum, copper and conductive fabric) as an electrodes are compared to improve sensitivity. Also, to find out the relation between electrode's gap and sensitivity, the experiment was performed and the optimal size of electrode is derived. Though these experiments, small leakage droplet up to 0.1 ㎖ can be detected by optimal design of sensor and these results will be reflected in the development of complete leakage sensing system as a future work.

Hospital, Goyang, Korea Purpose: Metabolic Syndrome (MetS) is defined as the coexistence of several metabolic risk factors. Diet is thought to play a major role in development of MetS. We attempted to determine whether the Korean diet is related to a reduced risk for development of MetS. Methods: A total of 425 healthy Korean adults were recruited by advertisement to Bundang Jesaeng Hospital from January 1 to June 30, 2009; those not taking regular medications and without diagnosis of disease were included. Data were collected on three-day dietary intake, anthropometric measurements, and diagnostic parameters, including levels of lipid panel, glucose, adiponectin, and inflammatory cytokines (interleukin-6 [IL-6], tumor necrosis factor-α [TNF-α]) for MetS from individuals enrolled in the study. The National Cholesterol Education Program (NCEP) scoring system was used for diagnosis of MetS. Results: Out of 425 (11.8%) subjects, 50 were diagnosed as having MetS. As NCEP scores increased, the levels of inflammatory cytokines (IL-6, TNF-α) showed an increasing tendency, however, the adiponectin level had decreased (P<0.0001). A greater amount of total vegetable consumption appeared to be associated with decreased risk for MetS. A higher carbohydrate consumption represented by the amount of rice intake (refined starch) appeared to be associated with higher risk of MetS. However, increasing consumption of rice combined with Kimchi showed an association with increased high-density lipoprotein cholesterol (56.7±1.6 vs. 62.8±2.2, P for trend: 0.0321) and decreased adiponectin level (9.0±0.8 vs. 11.4±1.2, P for tend: 0.0255). Conclusion: Among healthy Korean volunteers consuming an ordinary Korean diet, the prevalence of MetS was found to be 11.8%. Greater consumption of rice showed an association with greater risk of MetS, while greater consumption of rice combined with Kimchi, the main staple of the Korean diet, showed an association with lower risk of MetS.
