In this study, change of the view of love was analyzed by big data analysis in TV drama of married person's love. Two dramas were selected for analysis with opposite theme of love story. The sympathy of audience for the one month period from the end of the drama was analyzed by text mining and sentiment analysis. In particular, changes in the meaning of home meaning are identified. Home is not 'a place where a husband and wife play a social role', but 'a place where they can share real sympathy and one can be happy'. If individuals are not happy, they need to break their homes. In this study, the current divorce rate and the question regarding the matter should be considered. But based on Google Trends, in Korean society, interest in marriage were still higher than romance. It means that people prefer to 'a love to get marriage' in Korean modern society, than 'love for love affair'. It seems to be reflection of cognition change, marriage should be based on true love. This study is expected to be applied to the study of trend change through social media.

The incidence of colorectal cancer (CRC) in Korea has been gradually increased and it has been reported that dietary life is highly associated with the development of CRC. To investigate dietary attitudes and nutritional risk factors for CRC, we analyzed food intake of 34 patients diagnosed with CRC within 1 year and 51 subjects without gastrointestinal diseases as a control reside in Daegu·Gyeongbuk Area using semi-quantitative food frequency questionnaire. The results showed that dietary regularity and variety of food intake in control subjects was better than CRC patients whereas, CRC patients eat more frequently animal and vegetable protein foods, fried foods, green and yellow vegetables, and fruits than control subjects. Nutrient intake analysis showed that Vitamin A, E, K, C, sodium, magnesium, iodine, and cholesterol intake of CRC patients was higher than control subjects. Especially, after adjusting age and sex, regression analysis showed that Vitamin K (OR = 1.022, 95% Cl 1.003-1.043, p = 0.026) and sodium (OR = 1.001, 95% Cl 1.000-1.002, p = 0.032) were identified as risk factors for CRC. In the future, verification of the relationship between these nutrients and CRC risk and appropriate nutrient education will be needed for the prevention of CRC.

This study aims to provide basic data for maintaining and promoting health of obese middle-aged women who are interested in various chronic diseases such as cardiovascular disease and coronary artery disease by comparing and analyzing the effect on body composition and lipid metabolism through a 12-week Pilates mat exercise program for obese middle-aged women. This study targeted middle-aged women residing in Gyeonggi-do A, who are obese middle-aged women in their 40s and 50s with a body fat ratio of 30% or more, and had no regular exercise in the past three months. Obese middle-aged women(n=19) were divided into two groups, the Pilates mat exercise program group(n=9) and the control group(n=10), conducting exercise for 60 minutes three times a week for 12 weeks. As a result of analysis, the exercise group had a positive effect on body weight, skeletal muscle mass, body fat mass, body fat percentage, and BMI in body composition, but not in the control group. In the lipid metabolism, the exercise group had a positive effect on TC, TG, HDL-C, LDL-C, and FFA, but not in the control group. These results suggest that the 12-week Pilates mat exercise program conducted in this study is an exercise program that can prevent cardiovascular and chronic diseases in obese middle-aged women.

The rate of admission to facilities for people with developmental disabilities in Korea is very high for other types of disabilities. Therefore, 'community care', which supports life in the community for people with developmental disabilities, is very important compared to other types of disabilities. However, in Korea, families with disabilities are the problem of care and are appealing for the burden of support. This study analyzed practical cases through welfare institutional visits and interviews on support for community independence in Japan. As a result of the study, the transition of people with developmental disabilities to communities in Japan was centered on group home. The private sector is providing support for people with severe disabilities in group home to live in communities, and Sapporo City Hall is conducting private connections to solve the problem of caring for the developmentally disabled elderly parents. Accordingly, as Korean policy recommendations, it is proposed to expand group home, switch functions of living facilities for the disabled, cope with the problem of caring for the disabled by elderly parents, and provide preventive services through surveys on the actual condition of adults living alone. As practical suggestions, it is necessary to develop and distribute educational textbooks such as pictures to improve daily life skills for self-reliance, expand sufficient manpower and facilities in vocational training for self-reliance, and operate shelters for adults with developmental disabilities and their guardians.

Sensitive and specific monoclonal antibody (MAb) was produced from hybridoma (1H11-5) obtained by fusion of myeloma cell (V653) and spleen cell isolated from mouse immunized sulfamthazine (SMZ)-HG-KLH. Direct competitive ELISA was developed for rapid detection of SMZ in milk samples using MAb against SMZ with optimized conditions between MAb and SMZ-HG-HRP conjugate, and applicable conditions for analysis of milk samples were established. Detection range of immunoassay was 0.1 to 100 ppb. Recoveries from spiked raw milk and processed milk samples averaged 82.1-120.7 and 82.1-97.1%, respectively.

Leucine zipper motif consists of multiple periodic leucine residues, which forms amphipathic alpha helix. The hydrophobic nature of leucine zipper motif can dimerize proteins which contain this motif. Leucine zipper motif addition at C-terminus of single-chain Fv (ScFv) antibody induces its dimerization. Since the dimeric ScFv antibody contains two antigen binding sites (bivalency) like Y-shaped complete antibody, it could increase avidity. As a result, it could show higher antigen binding activity than monomeric ScFv antibodies. Based on this concept, monomeric chicken 8C3 ScFv antibody previously developed from chicken hybridoma was dimerized by the addition of leucine zipper motif at C-terminus of ScFv antibody. The dimeric 8C3 ScFv antibody specifically reacted with Eimerian sporozoite which causes Avian Coccidiosis. As expected, dimeric 8C3 ScFv antibody showed 3-folds higher antigen binding activity than monomer due to increased avidity. In addition, protien yields of dimer expression were 2-folds higher than monomer.

Purpose: This was a study of the effects of the vision training on binocular function and sensory anomaly for intermittent exotropia and recurrent intermittent exotropia patients. Mehtods: The change was examined weekly at the clinic during the 8 week vision training. The sample group of 17 patients, intermittent exotropia and recurrent intermittent exotropia patients without amblyopia, were chosen from the patients with the short and the long-distance deviation angle p=0.558 and p=0.338, and also greater than 10${\Delta}$, respectively. Results: The longdistance deviation angle was reduced by 67.9(${\pm}$32.7)%, and the short-distance deviation angle by 75.4(${\pm}$32.9)% after the vision training. There is an improvement on the binocular function and sensory anomaly according to the fusion reverse and Worth 4 dot tests. Conclusions: This study shows that the vision training is effective for phoria, function and sensory anomalyon of the intermittent extropia and recurrent intermittent exotropia patients.

In general, Personal Navigation Systems (PNSs) can be defined systems to acquire pedestrian positional information. GPS is an example of PNS. However, GPS can only be used where the GPS signal can be received. Pedestrian Dead Reckoning (PDR) can estimate the positional information of pedestrians using Inertial Measurement Unit (IMU). Therefore, PDR can be used for GPS-disabled areas. This paper proposes a PDR scheme considering various movement types over GPS-disabled areas as combat environments. We propose a movement distance estimation scheme and movement direction estimation scheme as pedestrian's various movement types such as walking, running and crawling using IMU. Also, we propose a fusion algorithm between GPS and PDR to mitigate the lack of accuracy of positional information at the entrance to the building. The proposed algorithm has been tested in a real test bed. In the experimental results, the proposed algorithms exhibited an average position error distance of 5.64m and position error rate in goal point of 3.41% as a pedestrian traveled 0.6km.

In this study, Laminaria japonica was used as a substrate for a mixed aerobic microbial consortium. Laminaria japonica is well-known as a representative brown algal biomass possessing advantages of cheap cost, and high productivity and carbohydrate content. A biological saccharification system was established by inoculating and enriching the mixed aerobic microbial consortium. Production of the soluble carbohydrate and reducing sugar at different hydraulic retention times (HRT) was observed. The efficiency of saccharification increased according to the decrease of HRT. The maximum saccharification yield in a continuous biological pretreatment process was 17.96 and 4.30 g/L/day for the soluble carbohydrate and reducing sugar, respectively at the HRT of 1 day. In contrast, the staccharification yield decreased drastically at the HRT of 0.5 day. Experimental results indicate that Laminaria japonica is a promising material for the production of useful products, in particular for the saccharification through a biorefinery process. It can thus be concluded that a continuous biological pretreatment process using a mixed cultivation system can be successfully employed for the biorefinery technology.

Large cast iron structures are used in casings and pipes in shipsand chemical plants. Broken parts in the casings and pipescan result in failures even when stresses are below the yield strength of the part's materials. Fatigue failure of a large cast iron structure is inevitable due to the design constraints and low reliability of the material strength. A small structure can be repaired by welding, but a large structure cannot because it cannot be preheated slowly and uniformly. This study shows that a large structure can be repaired by a cold joint method using a crack repair screw. Large cast iron structures were manufactured by GC 300, and their design stress is below 3.5 MPa. The tensile strength on notched specimens repaired by crack repair screws was 8.2 MPa. Therefore, the safety factors of structures repaired by crack repair screws have a value above 2.3 and are considered to be high values.
