The study was to investigate the functional properties of soy protein isolate hydrolyzed by immobilized α-chymotrypsin and the quality characteristics of soy ice cream made by the soy protein isolate treated with immobilized α-chymotrypsin. Up to the hydrolysis rate of 22.9%, treatement by immobilized α-chymotrypsin costed more time than that of α-chymotrypsin. Foam and emulsion capacity were decreased by the number of repetitive usage. Apparent viscosity and overrun of soy ice cream treated with immobilized α-chymotrypsin and α-chymotrypsin were shown similar tendency. In the sensory characteristics, soy ice cream by enzyme treatment was evaluated as much acceptable than untreacted soy ice cream in the item of beany flavor, icy feel and overall quality. For efficient use of immobilized α-chymotrypsin industrially, α-chymotrypsin immobilized on glass beads can be reused for about 11 times more than α-chymotrypsin.

The survey study was conducted to investigate the rice cake consumption pattern including the frequency of intake and the degree of preference and the area of improvement for Korean rice cake among college students. About the motive for purchases of rice cake, 'taste is good(43.3%)' was the highest, and 'eat as a snack' the next (42.9%). The reason which does not eat the rice cake frequently was uncomfortable to eat (24.1%), insipid(21.4%), not variously assorted(17.9%) in the order named. The college students surveyed were eating rice cake as a snack mainly. They wanted the rice cake to be charmed and be in pretty shape, and fusion style for gift. And they wanted to be rice cake more sweetened and cool taste like ice cream. Therefore, traditional rice cake is required for further research for the development of product which is more acceptable for the young adults.

<P><B>Abstract</B></P> <P><B>Background</B></P> <P>Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by intense pruritus and eczematous lesion. Substance P (SP) is an 11-amino-acid endogenous neuropeptide that belongs to the tachykinin family and several reports recently have supported the anti-inflammatory and tissue repairing roles of SP.</P> <P><B>Objective</B></P> <P>In this study, we investigated whether SP can improve AD symptoms, especially the impaired skin barrier function, in 2, 4, 6-trinitrochlorobenzene (TNCB)-induced chronic dermatitis of NC/Nga mice or not.</P> <P><B>Method</B></P> <P>AD-like dermatitis was induced in NC/Nga mice by repeated sensitization with TNCB for 5 weeks. The experimental group designations and topical treatments were as follows: vehicle group (AD-VE); SP group (AD-SP); and SP with NK1R antagonist CP99994 (AD-SP-A) group. Histological analysis was performed to evaluate epidermal differentiation, dermal integrity, and epidermal nerve innervation in AD-like lesions. The skin barrier functions and pruritus of NC/Nga mice were evaluated by measuring transepidermal water loss (TEWL) and scratching behavior, respectively.</P> <P><B>Result</B></P> <P>Topical SP treatment resulted in significant down-regulation of Ki67 and the abnormal-type keratins (K) K6, K16, and K17, restoration of filaggrin and claudin-1, marked reduction of TEWL, and restoration of basement membrane and dermal collagen deposition, even under continuous sensitization of low dose TNCB. In addition, SP significantly reduced innervation of itch-evoking nerve fibers, gelatinase activity and nerve growth factor (NGF) expression in the epidermis but upregulated semaphorin-3A (Sema3A) expression in the epidermis, along with reduced scratching behavior in TNCB-treated NC/Nga mice. All of these effects were completely reversed by co-treatment with the NK1R antagonist CP99994. In cultured human keratinocytes, SP treatment reduced expression of TGF-α, but upregulated TGF-β and Sema3A.</P> <P><B>Conclusion</B></P> <P>Topically administered SP can restore normal skin barrier function, reduce epidermal infiltration of itch-evoking nerve fibers in the AD-like skin lesions, and alleviate scratching behavior. Thus, SP may be proposed as a potential medication for chronic dermatitis and AD.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Topical Substance P treatment reduced AD-like symptoms in TNCB-induced NC/Nga mice. </LI> <LI> Topical Substance P treatment reduced epidermal acanthosis and expressed normal keratin profiles in AD-like mice. </LI> <LI> Topical Substance P treatment regulated both small nerve attraction and repulsion factors in AD-like skin. </LI> <LI> Topical Substance P treatment recovered skin barrier function and reduced pruritus in AD-like mice. </LI> </UL> </P>

The effects of acidification on phytoplankton composition were observed by enclosure experiments. The surface water of Lake Soyang was acidified to 5.5, 5.0, or 4.5 with H₂SO₄, and the change of species composition and biomass of phytoplankton were observed. Axenic cultures of two algae, a green alga(Scenedesmus obliquus) and a cyano bacterium(Microcystis aeruginosa) was also used to test the effects of acidification. Dominant phytoplankton in Lake Soyang were Asterionella in winter, and peridinium and Anabaena in summer. In acidified condition, dominant species changed from cyanobacteria to green algae. At pH 4.5, most algal cells showed morphological damage. Species richness decreased with decreasing pH. The growth rate of Anabaena declined at below pH5.5. Whereas, the growth rate of Peridinium, Fragilaria, and Asterionella decreased only at pH 4.5. Green alga, Desmidium and Dictyosphaerium, were Anabaena, green algal increased even at pH 4.5 and grew slower at neutral pH. In axenic cultures, the growth of Microcystis aeruginosa was inhibited at 4.0 and 5.0 and showed maximum at pH 9.0. Scenedesmus obliquus also grew well at pH 5.0 and showed maximum at 9.0 At pH 4.0, Scenedesmus did not grow at all.

The purpose of this study is to analyze social support networks among commuter couples in accordance with family life cycle. In this study, four different stages are considered as family life cycle: childrearing stage (from the period of childbearing to the second grade of elementary school), school stage(from third grade to six grade of elementary school), adolescent stage(from middle school to high school), and launching stage(more than 19 years old). The classification of the stages are based on the age of the first child. Our data suggest several important characteristics in the commuter couples' social support networks associated with family life cycle. First, emotional support tended to decrease as the stages of family life cycle have been progressed. Wife's relative showed clear decrease in providing emotional support. The reason for this tendency seems to be that burden for childrearing has been decreased as the commuter couples moved to the different family life cycle. Second, the commuter couples showed consistency in getting instrumental support, regardless of changes I family life cycle. The amount of receiving instrumental support did not show any significant changes, when compared to the groups of commuter couples which belonged to different stages of family life cycle. This result implies that the commuter couples are somewhat independent from receiving social support. Third, the amount of offering social support from wife's relatives was the primary social support network in offering childrearing and daily instrumental service. Fourth, husband's relatives were the major provider of material aids, whereas coworkers and friends frequently offered informational service and social activities. This finding suggests that intimacy among acquaintances and importance of social relationships are equally essential in maintaining social support networks. Friends were served as an intimate social support network, while husband's relatives and coworkers played the role of an important social support network.

The objectives of this study were to investigate the perceptions of Korean female university students for clothing pattern tendency and structural element of clothing pattern image dimension and to find how individual personality type influence the preferred clothing pattern characteristics. For this study, a questionnaire was designed and sent to 600 female university students of Daejeon, Seoul and metropolitan area. The tool used in this study was MBTI(The Myers-Briggs Type Indicator) Form G Korean version and for the analysis of data SPSS 10.0 package were used. 10 representative patterns for this study were floral, dot, stripe, check, animal, abstract & artistic, geometric, vegetable & leaf, paisely, patchwork pattern. The data were analyzed by factor analysis, arithmetic mean, One-Way ANOVA, χ^(2)-test. The major findings were as follows: Clothing pattern image dimension perceived by Korean female university students for 10 representative patterns were basic form, deluxe, specialty, and cultral dimension. Among them, basic form and deluxe dimension were major dimensions. In basic form dimension, dot pattern score was high indicating female students perceive it as light, comfortable, clean, cool and simple pattern image. In deluxe dimension, floral pattern scored high and in specialty dimension, abstract and artistic pattern scored high among other pattern image. In cultural dimension, geometric pattern and check pattern scored high. Based on other detailed analysis results, It is concluded that the personality type greatly influence clothing pattern evaluation. For example, in case of color combination of patchwork pattern, there was a difference in color preference depend on a personality type such as sensing(S) or intuition(N). Therefore, sensing personality type preferred adjacent color combination than contrast color combination. Detailed marketing strategy is necessary in planning textile design of merchandise plan.
