The effects of water flow rate and phytoplankton concentration on the growth of the sandy shore clam Gafrarium tumidum was investigated in a laboratory flume study using a $3{\times}3$ factorial design. After 60 days, shell length, shell weight and tissue dry weight increased significantly with phytoplankton concentration. For the effect of flow rate, growth was faster when flow rate increased from low to medium level; further increases in flow rate, however, either did not sustain faster growth or resulted in a reduction in growth. The condition index (CI) of a standard-sized clam was significantly higher at low flow rate than at medium and high flow rates and was negatively correlated with phytoplankton concentration. The uncoupled growth of shell and tissue in response to flow rate and phytoplankton concentration may be adaptations to low food environments, so that energy can either be stored to sustain life or reserved for gametogenesis during the reproductive period.

The objectives of this study were to investigate the images in men's hairstyle by hair color, tone, texture, and perceiver's gender, and to examine the characteristics of hairstyle appropriate to seasons. A quasi-experimental method by questionnaire was used, and the experimental design was $4{\times}3{\times}2{\times}2$(hair color$\times$tone$\times$texture$\times$perceiver's$\times$gender) factorial design. The subjects were 372 men and women in their 20s through 50s. five factors of men's hairstyle image were derived by factor analysis: individuality, dignity, romanticism, refinement, and activity. Black hair was perceived to be high in dignity and activity. Bright tone was perceived to be high in individuality, but low in dignity. Men's wave hair was perceived to be higher in individuality than straight hair, but lower in dignity. Perceiver's gender did not give significant influence on evaluation of all image factors. In brown, neutral tone was perceived to be higher in dignity. romanticism, and activity than dark or bright tone. In black, wave hair was perceived to be more refined than straight hair. Black hair matches with winter the most, and yellow matches with spring the most. In terms of tone, dark tone matches with winter; neutral tone matches with autumn; bright tone matches with summer. The results of this study verified that hair color and texture affect men's image perception, and matching hair colors are associated with seasons.

콘크리트의 일축압축실험에서 축하중이 발생함에 따라 새로운 균열이 발생하고 이 균열의 확장이 파괴의 주된 원인이 되는 경우가 대부분인데 이는 입자 결합 모델에서 입자간의 결합이 파괴되어 해석 대상체의 균열 모사와 유사하게 해석될 수 있어 콘크리트의 표준 공시체에 대하여 일축압축실험의 모사 가능성을 연구하였다. 그러나 입자 결합 모델은 해석 대상체를 입자간의 집합체로 모사하기 때문에 입자간의 결합을 결정하는 미시변수에 의해서 해석 대상의 거시물성이 변하게 되어 이들 변수간의 정량적인 관계를 파악하는 것이 중요하다. 본 연구에서 사용된 접촉 결합 모델에서는 총 8개의 미시변수가 있어 이들 변수와 일축압축실험결과 나오는 거시물성-탄성계수, 일축압축강도, 포아송비-와 콘크리트의 압축파괴거동에 관련이 있는 균열 개시 응력과 일축압축강도와의 비로서 5개의 거시물성에 대하여 부분배치법 및 회귀분석을 통하여 이들 간의 정량적인 관계를 도출하였고 그 결과 일축압축강도를 가정한 가상시료 및 조사 자료로부터 얻은 일축압축강도를 비교적 잘 모사할 수 있었다. 또한 해석을 수행한 공시체의 응력-변형률 곡선이나 응력 수준별 균열 발생의 빈도 및 파괴거동을 관찰한 결과 일반적인 콘크리트의 일축압축하중 하에서의 파괴거동과 상당부분 유사함을 보여 입자 결합 모델을 이용하여 콘크리트 공시체에 대한 일축압축실험을 잘 모사할 수 있다고 본다.

This study investigated the effect of different dietary fats and fibers on colon tumor incidence and cell proliferation, the levels of eicosanoids and polyamines in colonic mucosa of DMH-treated rats. The experiment was conducted on male Sprague Dawley rats using a 2 $\times$3 factorial design with two fats (corn oil and DHA-rich fish oil) and two fibers (cellulose and pectin) and a fiber-free control. The rats were find an experimental diet containing 15% (w/w) dietary fat and 6% (w/w) fiber for 25 weeks. Tumor incidence was Bower in rats fed fish oil as opposed to corn oil. The levels of arachidonic acid (AA) and eicosanoids ($PGE_2, and TXB_2$) in normal colonic mucosa were significantly lower in rats fed fish oil and there was a concomitant increase of docosahexaenoic acid (DHA). The levels of eicosanoids and AA in tumor tissues were significantly higher than those of normal colonic mucosa. The level of polyamines in normal colonic mucosa was not affected by dietary fats but was significantly lower than that in rumor tissues. Dietary fiber did not have a significant effect on rumor incidence and the levels of AA, eicosanoids and polyamines. Overall, fish oil rich in DHA reduced cell prolifiration and thus inhibited colon carcinogenesis through its effect on the distribution of AA and production of eicosanoids in normal colonic mucosa. However, its effect on colon carcinogenesis revealed a lack of consistency depending on the type of dietary fiber in diet.

Twenty-four multiparous crossbred Friesian dairy cows (60-90 days in lactation) were randomly assigned into a $2{\times}2$ factorial arrangement in a randomized complete block design. Factors were two levels of concentrate supplementation (1:2, high vs 1:1.2, very high; concentrate:milk yield) and two levels of high-quality feed block (HQFB) supplementation (non vs ad libitum block licking). Ruzi grass (Brachiaria ruziziensis) was fed as a roughage throughout the 70 day feeding trial. High level of concentrate fed group resulted in higher roughage and HQFB intakes, compared with very high concentrate supplemented group. HQFB supplementation tended to increase roughage intake and significantly improved milk yield (2 kg/hd/d in high concentrate supplementation) and quality (% fat) which resulted in higher economical return. HQFB was recommended to be used as a strategic supplement in lactating dairy cows especially when fed on low-quality roughages or crop residues.
