In an attempt to investigate mothers' perceptions of factors affecting preschool children's food preferences, their policy improving food intake and belief in food selection, in-depth interviews with 30 mothers who had preschool children were conducted in Daegu and Busan. The interviews were tape-recorded and the contents of interviews were analysed by researchers. Most mothers and children liked meats. It was found that children usually disliked vegetables such as onions, carrots, and green onions. Mothers perceived that many factors affected their children's food preferences: mothers' and fathers' food preferences, food offering at meals. mothers' food intake during pregnancy, children's food intake during weaning period, heredity peer pressure, and advertisements on television. Mothers made efforts to improve childrens food intakes in many ways: change of cooking method, emphasizing function of nutrients and food for health, conciliation and enforcement, and comparison to other children. The most affecting belief for mothers in food selection was family members' food preference. Health, balance in nutrient intake degree of food processes food additives, chemicals, convenience, diversity, and economy were also important beliefs to select food. Convenience was especially the primary belief in choosing and preparing children's snacks. Mothers offered frozen dumplings and meat, instant noodles, tuna, and ham for snacks for convenience. These results showed that mothers understood many aspects affecting children's food preference tried to improve children s food intakes and had several beliefs in food selection. We concluded that it is necessary to give information for mothers to make healthy snacks in a short time and chance to learn cooking skills.

Objectives: It is well known that genetic factors and environmental factors play major role in aging skin. In general, son and daughter take after their parents in appearance. But comparability of skin properties in Korean family has not been well estimated. So we evaluated the correlation of skin properties in Korean mother-daughter pairs. Methods: 10 couples of mother and daughter pair(n=20) participate in this study. Mothers and daughters were aged $50.6{\pm}2.459$ and $23.8{\pm}2.15$ years, respectively. Skin moisture, sebum, skin color and elasticity is measured using non-invasive method : Corneometer CM825, Sebumeter(MPA580), Mexameter MX18, Cutometer MPA580. Statistical analysis program we used is Minitab 14 Korea. Results: The Skin moisture of mother group was significantly higher than daughter group. And skin elasticity(R2) of the daughter group was significantly higher than mother group. In the results of correlation analysis between mother and daughter pairs, skin elasticity(R2) had high positive correlation(r=0.729, p=0.026). But skin moisture, sebum, melanin index, erythema index and skin elasticity(R5) did not be confirmed a significant correlation. Conclusions: Skin elasticity(R2) is the only factor that showed high positive correlation significantly in mother and daughter pairs. Mother and daughter share the genetic factors and environmental factors that influence skin aging. So, mother's aging pattern will be a good guide for anti-aging of daughters.

Ulcerative colitis (UC) is one of inflammatory bowel disease (IBD), characterized by chronic inflammatory response and dysregulation of immune function. The severity of US has been influenced by environmental factors and food habit. The immune modulatory, anti-inflammatory and steroidal medicine have been used for the treatment of UC. However, long-term administration of those medicine is accompanied with side-effect. So, it is necessary to develop the non side-effect medicine using natural product. Prebiotics influences intestinal condition and food consumption. The heredity, immunity and environmental condition are related with occurrence of UC. In recent study, UC patients had lower level of prebiotics such as Lactobacillus and Bifidobacterium compared with healthy people. Also, previous study announced that imbalance of enteric flora aggravates the severity of UC. The effectiveness of probiotics might affect colon ability and viable bacteria also could promote the proliferation of beneficial intestinal bacteria. Prebiotics, such as herbal medicine, could lead to balance of intestinal bacteria or increase beneficial bacteria. So, proper choice of herbal medicine could control the intestinal condition. This study aimed to investigate the effect of mixture of probiotics and prebiotics (synbiotics) on dextran sulfate sodium (DSS)-induced UC in vivo. The synbiotics consist of Lactobacillus buchneri, Polymnia sonchifolia and Glycine max Merr. in this study. To evaluate the effect of synbiotics, 3% DSS was administered in BALB/c mice and synbiotics was daily administered for experimental days. The administration of synbiotics regulated colon length shortening, body weight change and disease activity index effectively. Also, extract of synbiotics upregulated survival ability of Lactobacillus buchneri in gut condition. These results suggest that mixture of probiotics and prebiotics, called as synbiotics, could influence intestinal condition also regulate the colon disease. Synbiotics might be a therapeutic agent for treatment of UC.

Diabetes mellitus, commonly known as diabetes, comprises a group of metabolic disorders characterized by a high blood sugar level over a prolonged period of time. Diabetes is classified into type 1 diabetes and type 2 diabetes, and the incidence and prevalence of diabetes, mostly type 2, have increased remarkably in recent decades. A diagnosis of type 2 diabetes is greatly influenced by heredity, and it is important to prevent diabetes in people with a family history by improving lifestyle and environmental factors. Controlling overeating, obesity, lack of exercise, and stress is effective to prevent diabetes. The patient in this case report had impaired fasting glucose and mild hyperlipidemia. The patient experienced improvements in these sequelae after the administration of herbal medicine (Yangkyuksanwha-tang) for 12 weeks and the implementation of a plant-based diet. The complete blood count, XXXX, fasting blood sugar, HbA1c, insulin, and C-peptide levels were measured, and the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and HOMA-β were calculated according to the FBS and fasting insulin levels. Total cholesterol, triglyceride, FBS, and HbA1c levels all decreased after 12 weeks compared with baseline measures. There was no change in the insulin secretory ability; the C-peptide level did not change as a result of β-cell function; and the HOMA-β level reflected an improved insulin secretory ability.

Under Water Sensor Networks (UWSN) has gained attraction among various communities for its potential applications like acoustic monitoring, 3D mapping, tsunami detection, oil spill monitoring, and target tracking. Unlike terrestrial sensor networks, it performs an acoustic mode of communication to carry out collaborative tasks. Typically, surface sink nodes are deployed for aggregating acoustic phenomena collected from the underwater sensors through the multi-hop path. In this context, UWSN is constrained by factors such as lower bandwidth, high propagation delay, and limited battery power. Also, the vulnerabilities to compromise the aquatic environment are in growing numbers. The paper proposes an Energy-Efficient standalone Intrusion Detection System (EEIDS) to entail the acoustic environment against malicious attacks and improve the network lifetime. In EEIDS, attributes such as node ID, residual energy, and depth value are verified for forwarding the data packets in a secured path and stabilizing the nodes' energy levels. Initially, for each node, three agents are modeled to perform the assigned responsibilities. For instance, ID agent verifies the node's authentication of the node, EN agent checks for the residual energy of the node, and D agent substantiates the depth value of each node. Next, the classification of normal and malevolent nodes is performed by determining the score for each node. Furthermore, the proposed system utilizes the sheep-flock heredity algorithm to validate the input attributes using the optimized probability values stored in the training dataset. This assists in finding out the best-fit motes in the UWSN. Significantly, the proposed system detects and isolates the malicious nodes with tampered credentials and nodes with lower residual energy in minimal time. The parameters such as the time taken for malicious node detection, network lifetime, energy consumption, and delivery ratio are investigated using simulation tools. Comparison results show that the proposed EEIDS outperforms the existing acoustic security systems.

Heterostyly continues to fascinate evolutionary biologists interested in heredity, evolution, breeding, and adaptive function. Polymorphism demonstrates how simply inherited developmental changes in the location of plant sexual associations can have important consequences for population pollination and mating biology. In contrast to homozygous self incompatibility, only a small number of mating phenotypes can be maintained in the population because insect pollinators have limitations in achieving multiple segregation sites for pollen deposition. Field studies of pollen tube growth have shown that reciprocal style-stamen polymorphisms function to increase the capacity of insect-mediated cross-pollination. The genetic pattern of style morphs is well established in various taxa, but despite recent advances, the identity, number, and structure of the genes controlling the heteromorphic syndrome have been poorly elucidated. The phenomenon of heterostyly in buckwheat has been controlled by gene complex concentrate to S-locus. Homomorphic autogamous buckwheat strains were established by the interspecific hybridization. Backcrossing of this line to the common buckwheat (pin) and selecting homostylar progenies made it possible to introduce the self-compatible gene into common buckwheat. In the result, we obtained the BC₉F₂ generation, and defined the strong linkage between flower type and self-incompatibility by microscopic observation of pollen tube growth. This finding suggests that self-incompatibility character is not controlled by one gene. Moreover, we defined the strong linkage between flower type and self-incompatibility. It strongly supports the S supergene theory. Therefore, we have plan to elucidate the heterostyly self-incompatibility by using molecular genetics, proteome analysis and apply to exploitation of buckwheat improvement. In near future, the expression of heterozygous syndromes in genus Fagopyrum with single isolated heterozygous species may provide clues to early stages of polymorphic assembly and shed light on evolutionary models of heterozygous strains.

과학교육 매체로서 연극의 활용가능성을 탐색하기 위해 초등학생의 수준에 적절한 과학 연극 두 편을 개발하고, 개발된 과학 연극을 학교 현장에서 지도함으로써 과학 연극을 통한 과학 교수 학습의 효과를 살펴보았다. 개발한 연극은 미국의 원자폭탄 개발을 다룬 '맨해튼 계획'과 혈액형의 유전 방법을 다룬 '엄마, 난 O형 이래요' 두 가지로 전자는 과학 논쟁 연극이고, 후자는 과학 개념 연극이다. 또한 6단계로 구성된 과학 연극 수업 모형과 지도 교사를 위한 지도안을 구성하였다. 과학 개념 연극은 3학년 학생을 대상으로 실시하였고, 과학 논쟁 연극은 5학년 학생을 대상으로 실시하였다. 지도 교사는 연극 수업의 준비, 실시과정에서 일지를 통해 학급에서 일어났었던 일과 이에 대한 자신의 생각을 정리하였으며, 과학 연극 수업은 비디오로 녹화 분석되었다. 또 과학 연극에 대한 학생의 반응을 알아보기 위해 일부 학생을 대상으로 면담을 실시하고, 전체 학생을 대상으로 설문을 실시하였다. 면담은 연극 참여 학생 일부와 관람 학생 일부를 대상으로 지도 교사가 연극 수업 직후 비형식적 방법으로 실시하였다. 수업 직후 실시된 설문에서는 과학 연극 수업에 대한 반응을 5점 척도로 조사하고(4문항), 수업 전후의 생각을 비교하게 하거나 수업을 통해 알게 된 내용을 쓰도록 하였다. 연구 결과 두 과학 연극 수업에 대한 학생들과 지도교사의 반응은 매우 긍정적이었으며, '맨해튼 계획' 보다는 '엄마, 난 O형 이래요' 가, 남학생보다는 여학생이 좀 더 긍정적인 반응을 보였으며 또 다른 과학 연극 수업을 기 대하기도 하였다. '엄마, 난 O형 이래요' 의 경우 연극에서 다룬 과학 지식의 내용을 대부분의 학생들(93%)이 잘 이해했으며, '맨해튼 계획' 의 경우 연극 관람 후, 원자폭탄의 사회적 이용에 대한 보다 다양한 책임 소재를 인식하였다. 그러나 핵의 위력(위험성)과 원자폭탄의 피해 상황을 부각하여 인식하는 경향도 발견되었다. 이러한 결과는 과학 연극 수업시, 주제와 관련된 학습 활동이나 토론 등을 보다 적극적으로 계획하고 실시하는 것이 필요함을 시사한다. 한편 지도 교사는 연극이라는 형식이 매우 새롭고 다른 수업 방법으로 다루기 어려운 내용을 지도할 수 있음을 인식하였으며 과학 연극 수업에 학생들의 흥미와 참여도가 높은 것에 대해 만족해했다. 그러나 두 경우 모두 이러한 과학 연극 수업이 정규 수업 외에 교사가 별도의 시간을 할애하여 준비해야 한다는 점에서 어려움이 있음을 지적하였다.

P. alba ${\times}$ P. glandulosa는 산록부(山麓部)에서는 잘자라나 토양수분(土壤水分)이 부족한 산복(山腹) 이상(以上)에서는 잘자라지 않는 것은 수분요구도(水分要求度)가 높기 때문이다. 이와 같이 수분요구도(水分要求度)와 기공빈도(氣孔頻度), 기공(氣孔)크기 및 수분증산량(水分蒸散量)과 일치(一致)하는지를 조사(調査)하고 이러한 형질(形質)이 차대(次代)에 어느 정도 유전(遺傳)하는지를 알고저 본 시험을 실시하였다. 엽리면(葉裏面)의 기공빈도(氣孔頻度)(number/$mm^2$), 기공(氣孔)길이 및 폭과 수분증산량(水分蒸散量)($g/dm^2$)은 P. alba 는 높고 P. davidiana가 가장 낮았으며 P. alba ${\times}$ P. glandulosa 는 교배양친수(交配兩親樹)의 중간수치(中間數値)를 나타내었다. P. alba ${\times}$ P. glandulosa의 기공빈도(氣孔頻度)는 교배양친평균(交配兩親平均)인 이론치(理論値)와 일치(一致)하므로 교배양친(交配兩親)의 중간(中間)을 나타내고, 수분증산량(水分蒸散量)에서도 교배양친평균(交配兩親平均)과 P. alba ${\times}$ P. glandulosa 간에 회귀계수(回歸係數) $b_{yx}=0.97$로서 높은 회귀계수(回歸係數)를 나타내어 P. alba ${\times}$ P. glandulosa 의 수분증산량(水分蒸散量)은 교배양친수(交配兩親樹)의 중간(中間)을 나타내며 기공(氣孔)크기에서도 교배양친(交配兩親)의 중간(中間)을 나타내고 있다. 그러므로 이러한 특성(特性)은 불완전우성(不完全優性)으로 간주된다. P. alba ${\times}$ P. glandulosa와 교배양친수(交配兩親樹)에서 기공빈도(氣孔頻度), 기공(氣孔)크기 및 수분증산량(水分蒸散量)은 토양수분(土壤水分)의 요구도(要求度)와 일치(一致)함을 알 수 있었다.
