Two experiments were conducted to investigate the effect of feeding cyanidin 3-glucoside (C3G) high black rice bran on nutrient digestibility, blood measurements, growth performance and pork quality of pigs. In Exp. I, a total of fifteen pigs (19.91${\pm}$1.80 kg, average initial body weight) were used in assay of nutrient digestibility and blood measurements. All pigs were allotted to 5 treatments with 3 replicates according to a completely randomized design (CRD) in an individual metabolic crate. Treatments included 1) CON: basal diet, 2) BRB-2: basal+brown rice bran 2%, 3) BRB-4: basal+brown rice bran 4%, 4) CRB-2: basal+C3G high black rice bran 2% and 5) CRB-4: basal+C3G high black rice bran 4%. The digestibility of dry matter (DM), crude protein (CP), crude fat (CF), crude ash (CA) and crude fiber (CF) was not affected by dietary treatments. Serum triglyceride (TG) and high density lipoprotein (HDL) cholesterol concentrations were not affected by addition of C3G high black rice bran. However, at the end of experiment, pigs fed rice bran showed decreased tendency in total cholesterol concentration. Especially pigs fed C3G high black rice bran showed significantly lower total cholesterol concentration compared to pigs fed brown rice bran (p<0.03). There was numerically lower total cholesterol concentration with increasing levels of black rice bran in the diet. In terms of serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT), there were no significant differences among treatments, even though pigs fed CRB-4 showed the lowest GOT concentration compared to other pigs. In Exp. II, sixteen finishing pigs (average initial body weight 89.96${\pm}$0.35 kg) were divided into 4 treatments to investigate the effect of feeding C3G high black rice bran on growth performance and pork quality. There were no significant differences in average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) among the treatments. Pigs fed C3G high black rice bran showed numerical decrease in ADG and increase in FCR while not effecting feed intake. There was no significant difference in live weight, carcass weight, carcass rate, backfat thickness and carcass grade. However, pigs fed C3G high black rice bran tended to show lower backfat thickness than pigs fed basal diet. Pigs fed C3G high black rice bran showed a tendency of decreased TBA value than pigs fed basal diet, although there was no overall significant difference among treatments. In conclusion, nutrient digestibility, blood measurements, growth performance and pork quality were not significantly affected by feeding C3G high black rice bran to pigs. However, C3G high black rice bran might have an effect on lowering serum total cholesterol and decrease the TBA value in pork compared to control group and these effects might be due to high concentration of antioxidative compounds in C3G high black rice bran.

A group of 16 $Zn+Pb{\pm}Ag$ deposits distributed in the Pyeongchang-Jucheon area, Kangwon-do, South Korea, were semi-regionally investigated. These deposits are contact metasomatic and/or hydrothermal replacement types hosted in the carbonate-dominated Cambrian Machari Formation and Ordovician Ibtanri Formation, and also in the carbonate interbeds of the Precambrian argillic metasediments. Comparing some key aspects of the individual deposits, it is found that the ore deposits hosted in the Machari and Ibtanri Formations are mostly of steeply-dipping chimneys with or without skarn minerals and are rich in Ag and Pb>Zn in metal grade whereas those occuring in the carbonate interbeds of the Precambrian argillic metasediments are gently-dipping conformable lenticular orebodies mostly with skarn minerals and are generally poor in Ag and Zn>Pb. The skarn mineralization in the area appears to have occurred during the lower Cretaceous (118.7Ma) to mid-Cretaceous (107.8Ma) time assumed from the K-Ar dates of the Dowon and Pyeongchang granites which are closely associated with the skarn ore deposits. The Rb/Ba/Sr ratios of these granites indicate that they are of strongly differentiated anomalous granites, and the Nb vs. Y and Rb vs. Y+Nb plots fall on the field of volcanic arc setting. The contact aureoles are zoned, giving the sequence in order of increasing distance from igneous contact: garnet-wollastonite, granet-wollastonite-clinopyroxene and garnet-clinopyroxene in such as the Pyeongchang and Yeonwol 114 areas. Electron microprobe analyses reveal that garnets and clinopyroxenes are generally low in Fe and Mn. Garnets are grossular to intermediate grandite except for those from the Ogryong exoskarn which are richer in andradite, pyrope and spessartine fractions. This indicates that the oxidation state of skarn-forming environment at Ogryong was higher than at the other deposits. Clinopyroxenes are mostly salitic except for those from the Ogryong exoskarn which involve considerable amounts of hedenbergite and johansenite fractions. The ${\delta}^{18}O$ value of Jurassic biotite granite at Ogryong is higher (+10.21‰) than that of Cretaceous one at Chodun (+8.41‰). The ${\delta}^{13}C$ values of carbonate rocks range from -0.89‰ to 0.68‰ and the ${\delta}^{18}O$ values range from +11.91‰ to + 19.34‰ indicating that these carbonate rocks are of marine origin. However, the ${\delta}^{13}C$ values of skarn calcite and vein calcite are -4.80‰ and -12.92‰, and the ${\delta}^{18}O$ values are +5.56‰ and +10.32‰, respectively, indicating that these calcites are of hydrothermal origin. The ${\delta}^{34}S$ values of sulfide minerals range from +4.4‰ to +8.7‰ suggesting that the sulfurs are of magmatic origin.

화학 변화에 대한 학습자의 선개념과 이를 근거로 개발한 개념변화 수업 지도안을 학생들에게 투입하였을 때, 학습자의 학습 동기에 따라 개념변화 수업 모형의 효과가 어떻게 다르게 나타나는지 알아보았다. 이러한 연구를 통하여 학습자의 흥미나 태도, 동기 등 정의적인 측면을 고려하지 않고 단지 학습자의 인 지구조에만 초점을 맞춘 기존의 개념변화 수업 모형들을 재평가하고자 하였다. 연구 결과, 수업 전 학습동기가 높았던 학생들의 경우에는 교과서 중심의 전통적인 수업을 받은 학생들보다, 개념변화 수업을 받은 학생들이 '화학 변화' 개념을 이해하는 정도가 훨씬 높은 것으로 나타났다. 그러나 수업 전 학습 동기가 낮았던 학생들의 경우에는 개념변화 수업을 받은 학생들과 전통적인 수업을 받은 학생들의 '화학 변화' 개념에 대한 이해도에는 별다른 차이가 나타나지 않았다. 사전 학습동기와 사후 학습동기, 그리고 개념 이해도 사이의 상관을 조사한 결과에 따르면, 사전, 사후 학습동기와 개념이해도는 높은 상관관계를 나타냈다. 수업을 통해 유발된 사후 학습동기는 개념 이해도를 23.30% 정도 설명하였으며, 특히 사후 학습동기의 하위 요소 중에서 '자신감' 이 가장 높은 설명력을 가지는 것으로 나타났다. 개념변화 이론에서는 잠정적으로 전제하고 있는 학습자의 학습동기가 실제로 개념변화 수업이 이루어져 개념 획득이 일어나는 과정에서 매우 중요한 역할을 하고 있음이 본 연구를 통하여 밝혀진 것이다. 특히 학습 동기의 여러 하위 요소 중에서 '수업을 통한 학습자의 자신감 획득'은 '개념 획득'과 밀접한 관계를 가지고 있었다. 그러나 사후 학습동기 검사를 통하여 전통적인 수업과 개념변화 수업이 학습자의 학습 동기에 영향을 미치는지 알아본 결과, 교과서 중심의 전통적인 수업과 개념변화 수업은 모두 학습자의 학습동기를 유발하는데 효율적이지 못함이 밝혀졌다.

An aim of this study is to find out influenced factors of satisfaction degree on the clinical practice for the dental technology student and it can be provided the basic necessary data for the educational planning of the curriculum for the clinical practice. The target of study are selected form 7 junior health college students and colleges are located in around seoul form 14 junior health college throughout the nation. The questionnaries were distributed between 24th Feb to 30th July in 1997 to the 100 dental technicians who finished clinical practice and entered profession in 1997. All collected data were analysed by using SPSS/PC, Technical Statistic, One-Way ANOVA, Ttest, Person Correnlation Coefficient, Chrobach Alpha Coefficient and the result of the study is follow. 1) The satisfaction degree were classificated as 7 aspect and overall average score was 3.042. During that period satisfaction of personal relation aspect(M=3.737) shows highest level. Satsfiaction of clinical parctice(M=3.571) shows as second, Satisfiaction of environment(M=3.028), Satisfaction of guidance(M=2.915), satisfaction of subject are ordered of their scores. According to above study satisfaction's degree of subject show lowest level. 2) According to the result of verification of study. general character of student and satisfiaction degree has not much relation with sex, location of college, religion, period for enrolling college, teaching method of clinical practice. But the result show similar relation with following items. Satisfaction if subject and satisfaction of clinical practice(P=0.000), place of clinical practice and satisfaction of clinical practice(P=0.002), Academic record of college and satisfaction of clinical practice(P=0.000). 3) The relation of satisfaction(Subject, method of teaching, environment, period, rating, personal relation) of clinical practice and age of investigation's target Older student show higher satisfaction(P=0.040). Also method of teaching, environments, period, rating, personal relation has similarities with satisfaction. Therefore student who has higher satisfaction of clinical practice they also have higher rate for subject, environment, period, personal relation. 4) The result fo investigation, most interesting subject was crown & bridge and most difficult factor was too many simple-works to the student. One of ideal factor was discussing with counselor before they choose place for clinical practice. Third grade and first semester is most efficient time for clinical practice and 8 week is proper period for clinical practice. Clinical practice is absilutory mecessary and we find out most student rated positively. However we need more specific study about satisfcation of each subject. Because it shows lowest level and we need more pay attention for planning of clinical practice.

Background: Gefitinib and erlotinib are useful, molecular targeted agents in patients with non-small-cell lung cancer (NSCLC) who failed previous chemotherapy. We compared the efficacy and toxicity of two drugs in patients with squamous cell lung cancer, most of whom are male smokers. Methods: We retrospectively reviewed the clinical information on patients with NSCLC who were treated with gefitinib or erlotinib treatment at Chonnam National University Hwasun Hospital between July 2002 and November 2009. The overall response rate (ORR), overall survival (OS) and progression-free survival (PFS) were compared between the two drugs. Results: A total of 182 (100 gefitinib vs. 82 erlotinib) of 584 patients treated by targeted agents had squamous histology. Of the 182 patients, 167 (91.7%) were male and 159 (87.4%) were smokers. The ORR and disease control rate (DCR) were 4.9% and 40.6%, and there was no significant difference between gefitinib and erlotinib (ORR, 5.0% vs 4.8%; p=0.970; DCR, 40.0% vs 41.4%; p=0.439). The median OS in the gefitinib group was 12.1 months, and that in the erlotinib was 12.7 months (hazard ratio [HR], 1.282; 95% confidence interval [CI], 0.771~2.134; p=0.339). The median PFS for the gefitinib group was 1.40 months, compared with 1.37 months for the erlotinib group (HR, 1.092; 95% CI, 0.809~1.474; p=0.564). Skin rash ${\geq}$grade 3 was more common in erlotinib (12.2%) than gefitinib (1.0%, p=0.003) groups. Conclusion: This retrospective study showed that the two drugs appear to have similar antitumor efficacy and toxicity except for skin rash.

This study was based on the information provided by 1,180 elementary school children (630 boys and 550 girls) of 5th or 6th grade in Changwon and Gimhae of Gyeongnam province. They were asked about perception and preference for rice foods by questionnaires. The purpose of this survey was to find the way of encouraging rice intake and preference which is currently getting lower because of increasing simple westernized eating habits, and to provide basic information needed for inheriting and improving our traditional rice-based dietary culture. The results are summarized as follows. Most of subjects (91.2%) thought that steamed rice is better than bread for own health. The reason why they chose to eat steamed rice was 'because it is good for health' (61.2%), and 'because it is staple food item that we eat everyday' (26.4%). Seventy one percent of girls and 52.7% of boys gave the answer 'because it is good for health' as the reason for eating steamed rice. The reasons for the importance of the rice-based dietary culture were 'because of its superior nutritional value' (40.8%), and 'because it is our traditional eating culture' (28.6%). While significantly more girls (42.9%) answered as 'because of its superior nutritional value', more boys (39.0%) answered as 'because it is our traditional dietary culture'. More boys (59.0%) preferred noodles than girls' (54.7%), and fruits were preferred more by girls than boys as substitution foods for steamed rice showing significant difference (p<0.01). They wanted rice product developed in the forms such as Ssalamyun (29.8%), Ssalmandoo (24.1%), rice noodles (20.6%), and rice bread (15.6%). The preference score on rice products of subjects was one dish meals (4.27) and drinks (4.26), snacks (3.72), convenience foods (3.61), and steamed rice (3.44) in order. Preferred food showing points over 4 were Ssalbap (plain steamed rice) (4.29) in steamed rice type food, Kimchi bokeumbap (4.56), Bokeumbap (4.55), Bibimbop (4.45), Omelet rice (4.44), Kimbap (4.42), Ddukkuk (4.33), Curried rice (4.33), Jajangbap (4.28), and Ddukmandookuk (4.24) in one dish meal type food, Samgak Kimbap (4.26) in convenience type food, Songpyun (4.48), Injulmi (4.18), Teokbokki (4.71), Ddukkochiguyi (4.46), and rice cookies (4.24) in snack type food, and Shikhye (4.61) and Misugaru (4.28) in drink type food. Based on these results, it may be said that elementary school children think the rice-based diet is good for health and this dietary culture should be inherited and developed not only in a traditional aspect but also in a nutritional aspect. Therefore, more studies are needed to develop various forms of rice food products and cooking recipes.
