Kang, Hyeon-Seok. & Kim, Minji. 2018. “A Multivariate Analytical Study of Variation Patterns of Honorific Final Endings in KakaoTalk Dialogue”. The Sociolinguistic Journal of Korea 26(1). 1~30. On the basis of KakaoTalk conversation data, this paper investigates the variations found in the use of honorific final endings, expecially haeyo and hapsyo styles. For this study we collected 3,087 tokens of honorific final endings from the dialogue of 8 KakaoTalk group chat rooms. Through multivariate analyses using Goldvarb and LVS, we examined whether the linguistic and external constraints, which were claimed by Kang (2011) to constrain the usage of haeyo and hapsyo styles in spoken language, also operate in the KakaoTalk dialogues. The results of the analyses revealed not only far more variants in the KakaoTalk data (12 variants of haeyo and 6 variants of hapsyo) than in spoken language but also various additional variants realized with pronunciation spelling and partial omission of final endings. As in the spoken language, ‘sentence type’, ‘speaker's gender’, ‘rituality of utterance’, and ‘formality of situation’ were analyzed as constraints which had a strong effect on the variation. In the data examined, besides haeyo and hapsyo styles, new honorific styles of hao, hasoseo, seupjyo, handayo, hasem/hasam were also found. Two new types of variants which was not yet discussed in previous studies, were also observed in the data: variants of ‘syam’ and ‘syeom’ of hasem/hasam styles and two variants of ‘yo’ realized with consonant addition to the onset position.
We investigated the influence of germination and high hydrostatic pressure (HHP) treatment conditions on the conversion of functional compounds and antioxidant activity in adzuki bean. The adzuki bean germinated at 25°C for three- or six-days, and was later subjected to HHP at 0.1, 50, 100, or 150 MPa for 24 h. The highest polyphenol content (5.36 mg gallic acid equivalents (GAE)/g) and flavonoid content (0.91 mg catechin equivalents (CE)/g) were observed after germination for six days and HHP treatment at 100 MPa for 24 h, respectively. The total phenolic acid contents increased with increasing applied pressure from 88.86 to 208.26 μg/g (100MPa, 24h). Phenolic acids are divided into two categories; those that exhibit increased content upon HHP treatment, and those that exhibit decreased content. The increasing phenolic acids were gallic acid, chlorogenic acid, (+)-catechin, ρ-coumaric acid, ferulic acid, heperidin, salicylic acid, protocatechuic acid, cinnamic acid, naringenin. The total anthocyanin content decreased with increasing applied pressure from 22.42 mg/100 g to 6.28 mg/100 g (150 MPa, 24 h). The highest ABTS radical scavenging activity (8.02 mg eq AA/g) and DPPH radical scavenging activity (1.22 eq Trolox/g) were observed after germination for six days and HHP treatment at 100MPa for 24h, respectively. These results suggested that the combination of HHP and germination can lead to improved functionality in adzuki bean.
Since the encoder and resolver are expensive, it is difficult to apply it as a position sensor of a motor in a real industrial field. Optical position sensors, such as encoders and resolvers, are also difficult to mount because of their size and durability. Therefore, in order to solve these problems, we propose a system that uses a linear motor as a stator and a magnet plate as a mover, and a system that excludes a separate linear scale and uses two linear Hall sensors and permanent magnets to generate a conventional sine wave, A linear motor capable of detecting an absolute position and a movement position of a magnet, a control method thereof, and a technology development that can reduce a production cost by developing a position control system using a magnet mover that can improve stability and reliability.
정부는 기후변화로 인하여 변화하고 있는 해양생태계를 보전하기 위해 노력하고 있다. 이와 관련하여 정부는 해양생태계를 보전하고 관리하기 위하여 보호대상해양생물 77종을 지정하여 특별히 관리하고 있다. 산호의 경우 해양생태계를 예측할 수 있는 중요한 생물군 중 하나이며, 해양생물에게는 서식지를 제공하는 매우 중요한 역할을 하고 있다. 인간의 다양한 활동으로 인해 산호는 위협받고 있으며, 이에 대한 보전과 관리가 시급하다. 따라서 산호의 가치를 평가하여 이해하는 것은 정책 입안자 및 일반 대중 모두에게 산호의 지속적인 관리의 혜택을 입증 할 수 있는 효과적인 방법이 될 수 있다. 따라서 본 연구에서는 조건부 가치측정법을 적용하여, 국내 대표 산호군락지인 문섬 등 주변해역 생태계보호구역 내 산호군락지의 보전가치를 평가해보고자 한다. 이를 위해 전국 1,000가구를 대상으로 일대일 개별면접을 실시하여, 문섬 등 주변해역 생태계보호구역 내 산호군락지의 보전을 위한 대중의 지불의사를 평가하였다. 질문법으로 1.5경계 양분선택형 모형을 활용하였으며, 0의 WTP를 처리하기 위해 스파이크 모델을 적용하였다. 그 결과 문섬 등 주변해역 생태계보호구역 내 산호군락지의 보전을 위한 가구당 연간 평균 WTP는 3,016원이었으며, 유의수준 1%에서 통계적으로 유의했다. 이 값을 모집단 전체로 확장하면, 문섬 등 주변해역 생태계보호구역 내 산호군락지의 보전가치가 연간 589억원으로 계산된다. 본 연구는 산호군락지 보전을 위해 국민들이 상당한 금액을 기꺼이 지불 할 의향이 있다고 판단하였다.
This study was performed to evaluate the quality characteristics of functional Dasik prepared with a mixture of freeze-dried mealworm (Tenebrio molitor) powder and dried pollack powder along with assessment of the general and fatty acid compositions of mealworms. General compositions, except for moisture content of freeze-dried mealworm powder, were higher than those of raw mealworms. The ratios of saturated fatty acids and unsaturated fatty acids of freeze-dried mealworm powder and raw mealworms were 1:3.31 and 1:3.19, respectively. Amounts of oleic acid, which was the most abundant among unsaturated fatty acids, of freeze-dried mealworm powder and raw mealworms were 41.12 and 37.84%, respectively. For color values, greater content of freeze-dried mealworm powder in functional Dasik resulted in lower L and b scores, whereas a value increased. In the case of mechanical properties, greater content of freeze-dried mealworm powder resulted in significant reduction of hardness, chewiness, and gumminess. In the case of sensory evaluation, color, taste, and overall quality of DPMD50, which was prepared with a 1:1 ratio of freeze-dried mealworm powder and dried pollack, were the highest. It was concluded that DPMD50 is a nutritious combination of edible insects and fish for protein fortification for growth and the elderly.

Functional foods for health are often consumed among adolescents. To investigate functional food usage, this study surveyed 326 students aged 14-16. 56.3% of the subjects answered that they were interested in health. More than 76% of the subjects thought themselves to be very healthy. Users of functional foods made up 56.7%, and among all types of functional food, probiotic supplements were taken most frequently, followed by nutritional supplements>red ginseng products>enzyme containing products. Most users of functional food got the information on functional food through family (71.3%). 50.3% of users experienced the effectiveness of the functional food when they supplemented. After use, repurchase intent was 58.1%. In order to investigate the relationship between academic stress and functional food usage, groups were classified as stressful (n=124), intermediate (n=122), and low stress (n=84) according to self-perception about stress. There was no significant difference in the intake of functional foods according to academic stress. However, in the intermediate stress group, academic stress index was improved in the users of functional foods. In conclusion, the results of this study can be used to develop functional foods in the future, possibly helping to prepare nutrition education materials, reducing academic stress among adolescents with middle stress.
The objective of this study was to compare physicochemical, microbial, and antioxidant properties of domestic and imported wheat kernels for bread making. Two domestic (JK1, 2) and three imported (ND, DNS, and CWRS) kernels were compared. Domestic kernels had higher moisture contents, and lower ash and protein contents (p<0.05). In grain characteristics, JK1 had 13.62% of damaged kernels, which was the highest among the samples (p<0.05). JK2 was similar to imported kernels in the ratio of sound kernels, foreign materials, and damaged kernels. Kernel size of JK1, 2 was larger than the imported kernels; therefore, kernels area and perimeter were higher by the image analyzer. Domestic kernels hid lower total aerobic counts the imported kernels (p<0.05). Domestic kernels and DNS had no yeast, while NS and CWRS had yeast in kernels. DNS (3.08 mg gallic acid equivalent (GAE)/g) had the highest total polyphenol content (TPC), followed by JK1 (2.81 mg GAE/g). JK2 had the lowest amount of TPC as 2.26 mg GAE/g. Total flavonoid content (TFC) was the highest in DNS as 0.44 mg catechin equivalent (CE)/g and JK2 was the lowest as 0.12 mg CE/g. Domestic wheat kernels had lower protein content and lightness than the imported wheat kernels so that flour from domestic wheat kernels may have lower quality for baking.
Recently, interest in the development of alternative water resources has been increasing rapidly due to environmental pollution and depletion of water resources. In particular, seawater desalination has been attracting the most attention as alternative water resources. As seawater desalination consumes a large amount of energy due to high operating pressure, many researches have been conducted to improve energy efficiency such as energy recovery device (ERD). Consequently, this study aims to compare the energy efficiency of RO process according to ERD of isobaric type which is applied in scientific control pilot plant process of each 100 m3/day scale based on actual RO product water. As a result, it was confirmed that efficiency, mixing rate, and permeate conductivity were different depending on the size of the apparatus even though the same principle of the ERD was applied. It is believed that this is caused by the difference in cross-sectional area of the contacted portion for pressure transfer inside the ERD. Therefore, further study is needed to confirm the optimum conditions what is applicable to the actual process considering the correlation with other factors as well as the factors obtained from the previous experiments.
Elderly with dementia in geriatric hospitals (EDGH) are highly dependent on hospital meals. This study evaluated the foodservices satisfaction and food preference of the EDGH. The survey was conducted on 104 elderly with dementia (21 males and 83 females) in 4 geriatric hospitals in Seoul and Incheon in November, 2016. Data were collected from interviews using a questionnaire that consisted of 6 questions for foodservice satisfaction and 24 questions (10 categories) for food preference. The data were analyzed using SPSS ver. 20.0. The satisfaction with taste, saltiness, texture, and variety in foodservices was good, but the satisfaction with the amount was not, and the reason for leaving food was its large serving size. The subjects preferred soft boiled rice, noodles, porridges, meats, fish, seafood, vegetables, and fruits. Among them, they preferred more janchiguksu, red bean porridge, beef, croaker, oyster, spinach, and banana. Regarding the cooking methods, they preferred soup, grill, and boiling, but not frying. The also preferred Chinese cabbage kimchi, but they did not prefer hard kkakdugi. They did not prefer milk because of diarrhea, but they preferred yogurt. Therefore, to provide a satisfying meal for EDGH, it is necessary to develop a friendly diet considering their food preferences.

Nitrogen (N) loading from domestic, agricultural and industrial sources can lead to excessive growth of macrophytes or phytoplankton in aquatic environment. Many studies have used stable isotope ratios to identify anthropogenic nitrogen in aquatic systems as a useful method for studying nitrogen cycle. In this study to evaluate the precision and accuracy of denitrification bacteria method (Pseudomonas chlororaphis ssp. Aureofaciens (ATCC® 13985)), three reference (IAEA-NO-3 (Potassium nitrate KNO3), USGS34 (Potassium nitrate KNO3), USGS35 (Sodium nitrate KNO3)) were analyzed 5 times repeatedly. Measured the δ15N-NO3 and δ18O-NO3 values of IAEA-NO-3, USGS 34 and USGS35 were δ15N: 4.7±0.1‰ δ18O: 25.6±0.5‰, δ15N: -1.8±0.1‰ δ18O: -27.8±0.4‰, and δ15N: 2.7±0.2‰ δ18O: 57.5±0.7‰, respectively, which are within recommended values of analytical uncertainties. Also, we investigated isotope values of potential nitrogen source (soil, synthetic fertilizer and organic-animal manures) and temporal patterns of δ15N-NO3 and δ18O-NO3 values in river samples during from May to December. δ15N-NO3 and δ18O-NO3 values are enriched in December suggesting that organic-animal manures should be one of the main N sources in those areas. The current study clarifies the reliability of denitrification bacteria method and the usefulness of stable isotopic techniques to trace the anthropogenic nitrogen source in freshwater ecosystem.
The nitrogen isotope value in both ammonium and nitrate ion were determined at 9 stations during both June and August 2016, in order to understand the origin of DIN at the Han river. δ15N-NO3 and δ15N-NH4 values in 8 stations (CP, SB, MHC, P4, SJ, SBC, P2, SC) were no significant variation. However δ15N-NO3 and δ15N-NH4 values in KK (Kyeongan stream) showed significant different in comparison with 8 stations, with an apparent increase of nitrogen isotope values. These results indicate that antropogenic nitrogen source influence on KK station. Also the δ13C and δ15N isotope ratio of phytoplankton (Diatom and Cyanobacteria) in KK (Kyeongan stream) showed heavier values, compared to other study stations. These results indicate that nitrogen isotope value in phytoplankton effects by different nitrogen source in study sites. These results suggest that the analysis of stable isotope ratios is a simple but useful tool for the identification of dissolved inorganic nitrogen origin in aquatic environments.
The safety management of feeds has become a very important factor for food safety and legislation and system improvement are being implemented to prevent the hazardous factors from livestock products. The range of heavy metals in feed hazardous factors was similar among countries, but the As maximum limit was strengthened in Korea compared to China. Regulation of residual pesticide and radioactivity was only controlled in Korea. The range and maximum limit of mycotoxin were strictly controlled in China compared to Korea. In order to enhance the feed safety in Korea, it is necessary to improve the policy, strengthen the range of the feed hazard and the maximum limit and carry out the research related to the feed safety.
Most people seek a happy life and happiness positively affects sentiment, satisfaction with life, creativity, human relationship, business productivity, and even health and life extension. However, according to a survey in 2013, subjective happiness of adolescents (including university students) was very low compared to other age groups in Korea. Therefore this paper examined the effects of job-seeking stress, appearance recognition, financial situation, trust in government, and locus of control on university students' happiness using SEM (structural equation modeling). 207 university students in Seoul, Korea have been surveyed. At first, an initial experimental SEM model among these variables has been set up and reliability analysis has been conducted. Then multiple regression analyses on job-seeking stress and happiness as well as SEM analysis have been conducted. As a result of these analyses, the SEM model has been revised two times. The final SEM model passed the goodness-of-fit test (using RMR, GFI, NFI, CFI, and IFI indices). The final SEM model showed the followings. First, Higher job-seeking stress (especially sentimental part, rather than environment or action related parts) negatively affects happiness. Second, Trust in government also affects happiness both directly and indirectly. Third, Locus of control is affected both by trust in government and financial situation. Fourth, appearance recognition heavily affects job-seeking stress. In addition, appearance importance is higher than appearance interest, meaning that students who are not very interested in appearance usually recognize the importance of appearance. Finally, happiness is affected neither financial situation nor appearance recognition. Therefore, even either they are in a poor financial situation or not happy with their appearance, they can be happy if they have firm locus of control.
The objective of this experiment was to determine the effect of supplementation of hot melt extrusion (HME) processed Zn sulfate on growth performance, nutrients digestibility, small intestinal morphology and excretion of Zn in weanling pigs. A total of 200 piglets of mixed sex randomly allotted to four treatments on the basis of initial BW (7.15±0.81 kg). There were five replicates in each treatment with 10 pigs per replicate. The experimental treatments consisted of: 1) basal diet containing ZnSO4; 2) basal diet containing Zn-Methionine (ZnMet); 3) basal diet containing low level of nano-Zn as HME (ZnHME50); 4) basal diet containing medium level of nano-Zn as HME ZnSO4 (Zn-HME75). The average daily gain was improved by the ZnMet and ZnHME75 compared with the pigs fed ZnSO4 supplemented diets (p=0.009). Moreover, ZnHME75 and ZnMet affected on the ATTD of CP during phase 2 (p=0.014). The villus height (VH) was affected by increasing when pigs fed diets supplemented the ZnHME75 (P=0.044). The pigs fed diets supplemented ZnHME50 had significantly the lowest (p=0.037) Zn content in liver compared with other treatments. The Zn content in the feces was significantly higher (p<0.001) in ZnSO4 and ZnMet compared with ZnHME50 or ZnHME75. In conclusion, it could be concluded that dietary Zn can be reduced by 25% with ZnHME without any detrimental effect on performance of weanling pigs.
DMSP OLS 영상은 도시의 가로등과 건물과 같은 인공조명시설로부터 방출되는 야간 빛 에너지 세기 정보를 제공하는 것으로 알려져 있다. 이 자료는 대상 지역의 시가화 건조지역의 면적과 공간 범위를 추정하는 연구에 활용되어왔다. 본 연구는 DMSP OLS 연간 영상자료를 활용하여 중국 랴오닝 성의 시가지의 시계열 변화, 도시개발의 특성, 그리고 도시개발의 방향성을 분석하였다. 본 연구의 결과에 따르면, 야간 인공위성 영상에서 도출된 랴오닝 성 시가지의 공간적 확산은 이성의 경제수준을 향상시키기 위한 경제발전 정책을 잘 반영하였다. 선양과 다롄 등 대도시는 지속적인 도시 성장을 경험하고 있으나, 대부분의 도시들은 최근에 이르러 도시개발이 이루어진 것을 알 수 있었다. 선양, 안산, 다롄 등 랴오닝 성의 대도시는 북동-남서 방향의 축 선상에 위치한다. 이러한 도시발달 축은 연도별 시가화 중심점의 공간 분포에서도 확인되었다. 이와 같은 결과에 따르면, DMSP OLS 영상자료는 도시화 관련 연구를 수행하기 위한 공간적 대안 자료로서 활용 가능성이 클 것으로 기대된다.
