Purpose: A sampling scheme may significantly affect the accuracy of a sensor. This study was conducted to investigate the effects of sampling point locations on optical reflectance measurements of Chinese cabbage and kale plant leaves. Methods: Variability and similarity of multiple measurements for different parts of the leaves were compared. Results: The results indicate that the variability between the average and individual reflectance spectra was smaller for the blade part than for the vein part. Furthermore, the reflectance for the blade part over the upper leaf area was greater and more stable than those for the other parts for both the cabbage and kale leaf samples. Conclusions: The results provide guidelines for optical reflectance measurements of Chinese cabbage and kale plants. The effects of the number of sampling points, the number of leaves, and the relationships between optical reflectance and leaf components remain to be investigated in the future.

The purpose of this study is to investigate children's emotional problems (attention problem, aggression, somatic symptom, social withdrawal, depression) and to examine the relationship between children's emotional problems with family characteristics (parent education, parent job, family income), life-styles (gaming times, TV times, sleep time). The sample was 2,140 collections of second grade children and their parents who participated in Korea Youth Panel Survey on 2011. We analyzed the data which were collected by means of questionnaires and the data were analyzed with t -test, ANOVA, Pearson correlation analysis, and regression analysis with SPSS ver. 19.0. The results were summarized as follows. The level of children's emotional problem was relatively low on average. There is a significant difference in the children's emotional problems according to family characteristics and life-styles. There was a relationship between children's emotional problems (attention problem, aggression, somatic symptom, social withdrawal, depression) and life-styles (gaming times, TV times). The significant factors influencing the children's emotional problems are connected with father's education, mother's job, family income, family characteristics, gaming time and TV time of life style. It is noted that parent education level was an important factor for children's attention problem and aggression. Amongst children's life-styles, gaming time and TV time are negative factors for social withdrawal and depression.

Purpose: To determine whether maternal attitude toward sex during pregnancy and health-related quality of life could influence sexual function of pregnant women. Methods: In this study, 138 second and third trimester pregnant women completed self-report questionnaires during their visits to women's hospitals or community health centers to assess their general characteristics, attitude toward sex during pregnancy (PIES-M), health-related quality of life (EQ-5D), and sexual function (FSFI-6K). Multiple regression analysis was performed to test the research model with SPSS version 23. Results: Pregnant women who had discontinued their sexual life after recognizing their pregnancy accounted for 27.5% of women questioned. The average sexual function score of pregnant women was higher in the second trimester than the third trimester. Attitude toward sex during pregnancy (${\beta}=-.38$, p<.001), maintaining sexual life (${\beta}=.20$, p=.028), health-related quality of life (${\beta}=.18$, p=.030), and adverse symptoms during sex (${\beta}=.18$, p=.042) were determinants of sexual function during pregnancy. Conclusion: Nurses in antenatal care units need to help pregnant women maintain a positive attitude toward sexual activity during pregnancy and manage their health-related quality of life to maintain their sexual life during pregnancy.

Three trials were conducted to study the effect of processing method on performance, apparent nutrient and amino acid digestibilities in growing-finishing pigs fed lupine seeds. Ground, expanded or flaked lupine seed was prepared for the trials. In trial 1, a total of 72 growing barrows ($Landrace{\times}Large$ $White{\times}Large$, initial BW of $54.22{\pm}5.87$ kg) were allocated to three treatment diets containing 15% percent of differently processed lupine seed for 28 days. Each treatment had four replicates comprising 6 pigs each. In trial 2, a total of 48 finishing barrows ($Landrace{\times}Large$ $White{\times}Large$, initial BW of $84.40{\pm}6.84$ kg) were subjected to three treatments for 21 days. The experimental design was the same as trial 1 except for supplementation with 20% of lupine seed. Each treatment had four replicates comprising 4 pigs each. To evaluate the ileal digestibility of amino acids, a total of 9 barrows ($Landrace{\times}Large$ $White{\times}Large$), with an average initial BW of $41.07{\pm}1.98$ kg, were fed with ground, expanded or flaked lupine for 7 days. Each pig was surgically equipped with a simple T-cannula fitted in the distal ileum. Amino acid composition and presence of anti-nutritional factors (ANFs) in processed lupine sources were also evaluated. The results showed that there was no significant difference (p>0.05) in lupine amino acid composition due to the different processing methods. Expanded and flaked lupine significantly decreased (p<0.05) the concentration of ANFs compared with ground lupine. There was no effect (p>0.05) on the growth performance in growing pigs. However, processing method had a significant effect (p<0.05) on average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) in finishing pigs. There was no effect (p>0.05) of the different processing methods on the digestibility of dry matter (DM), gross energy (GE), ether extract (EE), Calcium (Ca) and phosphorus (P), but expanded lupine could significantly increase (p<0.05) the apparent digestibility of CP in finishing pigs. Furthermore, expanded lupine had a higher (p<0.05) apparent ileal digestibility for most indispensable and dispensable amino acids compared with ground and flaked lupine. It was concluded that expanded lupine could be beneficial in improving lupine's quality and improve performance and nutrient utilization in growing-finishing pigs.

This study investigates and analyzes the total amount of energy consumption and $CO_2$ emission during the material manufacturing, transportation, construction, operation, and disposal phases of eight elementary school buildings in South Korea. Toward this ends, the hybrid LCA model is proposed. The life cycle energy consumption and $CO_2$ emission of eight case buildings are assessed using the hybrid LCA model with an assumption that the operation period is 40 years. As a result, the embodied(sum of the energy consumption in the material manufacturing, transportation and construction phases), operational and disposal energy were 2,279, 11,182, $228Mcal/m^2$, respectively, on average. The average embodied, operational, and disposal $CO_2$ emission were 604, 2,708, 60 kg-$CO_2/m^2$, respectively, on average. This result indicates that about 17% of life cycle energy (or $CO_2$ emission) is consumed in the material manufacturing, transportation and construction phases. Thus, it is necessary to consider the embodied energy and $CO_2$ emission to reduce the life cycle energy and $CO_2$ emission of school buildings. In addition, while the insulation standard of building have been provided based on the climate zone, energy consumption in operation phase still varied depending on the regions in this study. Thus, the insulation standard of building needs to be improved through considering the climate of regions in detail.
