  • The purposes of this study were to investigate 1) the difference of cognitive evaluation on body exposure of female clothing, ann 2) purchase frequency and intention of wearing according to demographic variables. The instrument of this study consisted of response scale and stimuli. Thirty three items of 7.point Likert scale were developed to measure cognitive evaluation of the people who responded. The stimuli were 7 types of clothing, differing exposure parts and style on line drawing. The sample included 450 subjects, consisting of 231 in Seoul and 219 in Chun-nam Province. Statistics applied for analysis were frequency, percentage, mean, standard deviation, correlation, t-test, F-test, Duncan's multiple range test, factor analysis. The Results were: 1. Constructing factors of cognitive evaluation consisted of elegance, sensuality, attraction, individuality. There were significant differences in every factor on each types of clothing. 2. The evaluation toward each types of clothing was influenced by the subjects' sex, age, and residence. 3. Purchase frequency and intention of female subjects' wearing were very low, and there were significant differences on demographic variables.

  • The impact sound of the golf club is one of the major factors to purchase it. Sound qualify evaluation techniques are mostly developed for harmonic sounds. Sound quality metrics for the impact sound is proposed in this study. Jury test, one of the typical subjective evaluation scheme, is carried out for evaluating the sound quality of 11 different golf drivers. Above subjective classification results are assumed to be the right answers. Conventional objective evaluation methods such as Zwicker loudness sensory pleasantness are calculated. Wavelet analysis and instantaneous loudness are applied in order to evaluate the transient sounds, which shows better correlation with the results from those by jury test.

  • 본 연구는 국내와 외국의 건물 내장재 화재성능평가방법을 고찰하고 국내에는 도입되지 않은 실대 화재실험인 Room Corner Test를 국내 내장재중 석고보드와 합판을 대상으로 그 적용성을 위한 실험을 진행하였다. 현재 국내 내장재의 평가규정은 Bench-Scale Test에 의존하고 있으나, 미국, 일본 유럽등에서는 Room Corner Test를 적용한 실질적인 재료의 화재성능평가를 시행하고 있다. 실험 결과, NFPA 265에 의한 석고보드 및 ISO 9705에 의한 합판의 성능은 양호한 것으로 판단되었다. 현재 국내 내장재에 적용되는 등급분류의 평가방법은 재료의 실제 화재성능 평가에 한계가 있으므로 향후 Room Corner Test의 적용과 더불어 Bench-Scale Test 결과를 토대로 화재성능을 예측하는 화재모델을 이용하는 평가 방법의 도입이 필요하다.

  • Crickets have been attracting considerable interest in the field of nutrition and toxicology due to the global exhaustion of food resulting from a growing population. The cricket is normally eaten in several countries after roasting, similar to the grasshopper; however, safety evaluation data on cricket powder is limited. Here, we performed general toxicity studies of cricket powder including a single, 2-week repeated dose range evaluation test, a 13-week repeated oral dose toxicity test in Sprague-Dawley rats, a single oral dose toxicity test in Beagle dogs, and a skin sensitization test in guinea pigs following the Organization for Economic Cooperation and Development test guidelines 406 and 408 in addition to Good Laboratory Practice. To investigate the NOAEL and target organs of cricket powder, Sprague-Dawley rats were allocated to 4 groups: vehicle control, 1,250 mg/kg, 2,500 mg/kg, 5,000 mg/kg dose test groups and cricket powder was administered over 13 weeks after single dose and dose range finding studies in rats based on the results of the single oral administration toxicity study in rats and Beagle dogs. The results of the study showed that the NOAEL of cricket powder was over 5,000 mg/kg for both sexes of rats without adverse effects in a 13-week repeated oral toxicity study and there was no skin hypersensitivity reaction. Therefore, our results reveal that crickets can be widely used as a new substitute food or nutrient resource.

  • This study was to secure the safety of poor appearance distribution concrete poles effectively and to reduce the replacement costs of them by developing a soundness evaluation index. The researcher of this study investigated poor appearance types of concrete pole, collected 53 of test samples, and tested pole strength. As a result of strength test, only 17 percent of poor appearance concrete poles were below 2.0 of safety factor spec. As results of multiple regression analysis, it is verified that surface air void, horizontal crack, net-shaped crack, elapsed year, vertical crack, and deterioration in concrete compressive strength have statistically negative effects on safety factor of concrete poles in a significant level. The researcher set up a soundness evaluation index by using multiple regression equation, and suggested that poor appearance concrete poles should be replaced or reinforced only in case of soundness evaluation score of 150 or above.

  • Unlike most bacteria, Treponema pallidum subspecies cannot be readily isolated or sustained in cell culture for numerous generations. In korea, two non treponemal tests are currently considered as standard; the VDRL slide test and RPR card test. These tests are based on an antigen composed of an alcoholic solution containing measured amount of cardiolipin, cholesterol, and sufficient purified lecithin to produce reactivity. The nontreponemal reagin tests measure immunoglobulin M (IgM) and IgG to lipoidal material released from damaged host cells as well as to lipoprotein-like material and possibly by cardiolipin released from the treponemes. The object of the evaluation was to evaluate the performance of the Mediace RPR kit on the automated biochemistry analyzer system as a method for screen method of syphilis as well as to identify BFP possibility. For evaluation of routine screening test, a total 2,380 specimens tested by Mediace RPR from 28th Oct, 2007 to 22th Feb, 2008. For evaluation of BFP possiblility, we measured samples which have potential BFP reaction in Syphilis test such as ANA (anti-nuclear antibody) positive (135 samples), CRP (C-reactive protein) positive (100 samples), RF (Rheumatoid factor) positive (26 samples), and other potential BFP cases (17 samples) including total 278 samples. These samples were tested quantitative test Mediace RPR with Hitachi 7600 P module. For comparison with current manual test, VDRL slide test were performed. Of these 2380 specimens, 2350 were negative, 30 were positive, and one were positive with TPHA. Both methods agreed for 2356 (98.9%) samples. Of the 30 samples showed positive results over 1.0 R.U, 6 samples showed positive results with VDRL test. Of these 6 samples, 1 samples showed positive with TPHA test. The combination of the Automated Biochemistry analyzer and VDRL test for retest can be increase efficiency of syphilis screening test.
