This paper examined effects of three types of written corrective feedback (CF) on L2 learners’ grammatical accuracy in writing, focusing on the use of verb tense and articles. Within Ellis’ (2008) typology of CF, the present study focused on direct, indirect, and metalinguistic CF. The feedback was provided at each stage of writing, and the participants were to write three new pieces of writing. Changes in the accuracy of the grammatical targets were measured. Results indicated that despite the limitations of the small number of the participants, positive changes in the grammatical accuracy were found with metalinguistic CF for verb tense and with indirect CF for articles in new pieces of writing. In addition, unlike previous studies, a negative role of direct written feedback was observed in the present study.

As the 3D laser scanning technology capable of databaseing large sewage box culverts becomes possible, it is necessary to develop a standardization manual that can clearly distinguish the structural and operational defect types of box culver and analyze the defect data. In this study, we collected and analyzed defects in sewage box culverts of 14,827m in total by selecting three districts in Korea. The major defects were surface damages, and their defect densities were 2.17 m2/m, 0.27 m2/m and 0.10 m2/m for aggregate exposure, Steel reinforcement exposure, and Steel reinforcement projecting. In order to support the decision of the box culverment management, it was divided into five grades and each defect code and defect score were allocated. The results of this study are useful for the diagnosis of the sewage box culverts in Korea and it is expected to support a decision making for management.

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.

PURPOSES : The objective of this study is to identify the characteristics affecting traffic accidents that have occurred in 564 industrial complexes nationwide from 2011 to 2015.METHODS : The traffic accidents were specified using various factors such as industrial complex type (national VS. general), industrial complex degradation (old VS. non-old), location of complex (capital VS. non-capital), and traffic law violation (speeding, signal violation, and median invasion). The average number of crashes and accident ratio (fatal, severe, and both) in terms of characteristics of industrial complexes were calculated. With a sample of crashes of the industrial complexes for 5 years, statistical significances were tested to analyze and compare the differences based on industrial complex and traffic law characteristics using parametric and non-parametric methods.RESULTS: From statistical results, it is observed that the crash frequency occurring in old industrial complexes is three times higher than that in non-old industrial complexes. Old industrial complexes located in a capital area, old national industrial complexes, and old general industrial complexes are considerably related to higher crash frequency, but the fatal accident ratio appeared to have no statistical difference across industrial complex characteristics. Severe crashes are more likely to occur in non-old industrial complexes on an average.CONCLUSIONS : It is necessary to eliminate potential threats to roads and traffic in the same manner as illegal parking in industrial complexes through the restoration of old industrial complexes. To improve the efficiency of road infrastructure, efforts should be made to improve traffic safety in accordance with industrial characteristics such as planning and operation of relevant local government programs.

The ocean is used as the term of sea, it is expressed as a large sea. Marine tourism is an activity that takes place in the sea and on the coast. Many experts prospect that the 21st century will be the century of ocean. In recent years, many countries are interested in ocean and marine tourism can be significantly developed in the future. Jeju Island is an island formed by a volcanic eruption, which has a very high landscape value, and It is an oceanic climate with a yearly high temperature due to turbulent flow throughout the years, But Marine tourism is not developed. The purpose of this study is clarify the Marine Tourism activity types, Marine Tourism satisfaction and revisit intention of Chinese Tourists visiting JeJu island. And studies what is the needed activity types of Chinese Marine Tourist in future. This study deals with on the activity types, satisfaction and revisit intention of JeJu Marine Tourism With 252 effective responses gathered from an onsite survey. The statistical analysis of the data was conducted using techniques of frequency analysis, t-test and anova analysis.

Altar architecture is a kind of sacrificial building, mainly formed in altar. Central architecture of Altar architecture is relatively simple. However, various attached building are necessary for worship. Among them, Sinsil which is a place to seal a God’s tablet, is very important. The central government of the Joseon Dynasty attempted to define the local sacrificial system and make it customary as a way to strengthen the centralization based on Confucianism. Nonetheless, the altar architecture of the province without detailed regulations, were managed and underwent repairs according to the political situation of the state and local circumstances. Sinsil, which is an important component of the altar architecture, best reflects this situation. Therefore, it was possible to grasp the situation of the altar architecture of the province in the Joseon Dynasty by analyzing the Sinsil through various documents. As a result of analysis, it was divided into six types. In addition, It is also found that there are temporal relation between these six types.

T-O 지도 혹은 O-T 지도라 불리는 중세의 세계지도는 지도라기보다는 중세유럽의 기독교도들이 인식하고 있던 세계관의 이미지 그 자체였다. 본 연구는 T-O 지도의 유래와 유형화를 시도하고, 어떻게 非아르메니아 풍의 지도가 누구에 의해 제작되었으며, 언제 T-O형 지도가 아르메니아어로 제작되어 아르메니아에 존재했는지 규명함과 동시에 어떤 유형의 T-O 지도로 자리매김할 수 있는지 지도학적 특징을 고찰하는 데 목적이 있다. 그 결과, T-O 지도의 T는 아시아를 동쪽 상단에 배치하기 위해 고안되었거나 타우(Tau) 십자가에서 기원한 것으로 추정되며, 아르메니아 T-O 지도는 14세기 후반 카파 출신의 아르메니아인에 의해 제작된 지도임이 밝혀졌다. 또한 이 지도는 서구의 마파 문디의 T-O 지도와 달리 예루살렘이 상세히 묘사되어 있고 비교적 사실에 가깝게 제작된 지도임이 규명되었다.

This study investigated the effects of two types of corrective feedback (CF), recasts and metalinguistic feedback (implicit vs. explicit CF), on the development of implicit and explicit knowledge of English articles. It also examined the relationship between learners’ language aptitude, in particular language analytic ability, and their knowledge development through different types of CF. Six intact intermediate communication English classes (a total of 104 students and two English-speaking teachers) at a university participated in the present study. In CF groups, learners received recasts or metalinguistic feedback (MF) to the errors of the English articles during communicative activities, while no CF was given to the control group. The study employed a pretest-posttest-delayed posttest design, and four different tests were used to measure learner implicit and explicit knowledge. The study found both recasts and MF effective in the development of implicit knowledge and selective effects of recasts on the improvement of explicit knowledge. This suggests that both implicit and explicit CF bring about the development of implicit and explicit knowledge. In addition, language analytic ability was found to be closely related to learners’ gains through both CF and development of explicit and implicit knowledge of English articles.

The comparison of physicochemical properties and cell structure of texturized vegetable protein (TVP) and different types of meats (beef, pork, and chicken samples) were studied. TVP from the blend of 40% isolated soy protein (ISP) and 60% wheat gluten (WG) was texturized with a twin-screw extruder at 100 g/min feed rate, 45% moisture content, 250 rpm screw speed and 140℃ die temperature. The nitrogen solubility index, integrity index, chewiness, longitudinal cutting strength and microstructure of TVP were similar to the chicken sample, when compared to the other meats. However, water absorption capacity (WAC) of TVP (217.38%) was significantly (P<0.05) higher than those of meat samples (109.53 to 165.35%). The microstructure of TVP showed the fibrous structure. Non-uniform air cells were observed in the microstructure of TVP, which could indicate high WAC. The study demonstrated that the physicochemical and cell structure of TVP from the blend 40% ISP and 60% WG with 45% moisture extrusion process was similar as chicken sample.

The purpose of this study was to examine the effect of different types of frying oil on the quality of yakgwa such as expansion rate, color, moisture content and rheological properties. Yakgwa fried with corn oil showed the highest expansion in width and length, and rice bran oil in height. With regard to the overall expansion rate, yakgwa fried with rice bran had the highest value. As for lightness and yellowness, yakgwa fried with soybean oil had the highest lightness (34.74), while yakgwa fried with grape seed oil had the lowest lightness (29.82). As for redness, however, no significant difference was found. Regarding fat content, yakgwa fried with rice bran oil showed the highest value with 18.91%, while yakgwa fried with corn oil and canola oil showed the lowest value. No difference was found in moisture content according to the type of frying oil. In relation to the acid value, yagkwa with soybean oil showed the lowest value of 0.24±0.66; as for peroxide value, yagkwa fried with rice bran oil showed the lowest value of 3.59±1.74 meq/kg. No difference was found in hardness, cohesiveness and resilience according to the type of frying oil. Yagkwa fried with corn oil and canola oil showed the lowest value in terms of adhesiveness and chewiness, respectively. The results of the sensory evaluation showed not significance difference in overall preference, but yakgwa fried with rice bran oil had the highest value of 5.93±1.87.

In this study, composite PAN-based ACNFs embedded with MgO and MnO2 were prepared by the electrospinning method. The resultant pristine ACNFs, ACNF/MgO and ACNF/MnO2 were characterized in terms of their morphological changes, SSA, crystallinity and functional group with FESEM-EDX, the BET method, XRD and FTIR analysis, respectively. Results from this study showed that the SSA of the ACNF/MgO composite (1893 m2 g–1) is significantly higher than that of the pristine ACNFs and ACNF/MnO2 which is 478 and 430 m2 g–1, respectively. FTIR analysis showed peaks of 476 and 547 cm–1, indicating the presence of MgO and MnO2, respectively. The FESEM micrographs analysis showed a smooth but coarser structure in all the ACNFs. Meanwhile, the ACNF/MgO has the smallest fiber diameter (314.38±62.42 nm) compared to other ACNFs. The presence of MgO and MnO2 inside the ACNFs was also confirmed with EDX analysis as well as XRD. The adsorption capacities of each ACNF toward CH4 were tested with the volumetric adsorption method in which the ACNF/MgO exhibited the highest CH4 adsorption up to 2.39 mmol g–1. Meanwhile, all the ACNF samples followed the pseudo-second order kinetic model with a R2 up to 0.9996.

The purpose of the study was to compare two different MBTI personality types by evaluating the influence of perceived risk on brand and store loyalty and purchase intention. 340 questionnaires were used for the analysis. For statistical analysis, SPSS 20.0 and AMOS 20.0 were performed, and frequency tests, reliability analyses and Structural Equation Modeling were used. The results of SEM analysis, confirmed that one question of brand loyalty and one question of store loyalty were inappropriate for this study. Thus, these two questions were removed and the research model was modified. To determine the goodness of fit of the research model, convergent validity was tested. Most items fell into the goodness of fit, and the average coefficient was fulfilled. According to the results of a path coefficient analysis for the Judging type, perceived risk has a significant influence on brand loyalty and brand loyalty also affected store loyalty. Furthermore, brand loyalty and store loyalty have a significant effect on purchase intentions, but perceived risk did not affect brand loyalty for the Perceiving type. Brand loyalty influences store loyalty and purchase intentions, but store loyalty did not influence purchase intentions. As a result of this study, it is concluded that considering consumers' personality types is critical to developing strategies that enhance brand loyalty.

Seasonal distribution of disease vector species including mosquitoes and ticks plays a key role in establishing risk managementof vector-borne disease. However, environmental factors affecting abundance and distribution of vector species are notcurrently well understood. Therefore, we conducted a two-year field sampling to address the population dynamics of mosquitoesand ticks in Gyeonggi-do in 2015 and 2016. In 2015, the population density was highest in May for ticks (e.g. Haemaphysalislongicornis) and June for mosquitoes (e.g. Aedes vexans), whereas both pest groups peaked in August in 2016. Culexpipens (82.3% Species Ratio), Ae. vexans (77.3% SR), and Anopheles sinesis sp. (45.3% SR) were the most dominantspecies in urban area, cow shed and wild bird refuge, respectively. For ticks, H. longicornis (47.7% SR) was the mostdominant throughout four potential habitats.

The purpose of this study was to investigate the effects of lumbar stabilization and sling exercise on visual analogue scale (VAS), Korean Oswestry Disability Index (KODI), and stability index (ST) in patients with chronic lower back pain (CLBP). This study included participants with a VAS scale of 6 or higher and a KOD of 20-40%. They were randomly divided into a mat group (n=15) to perform lumbar stabilization exercises and a sling group (n=15) to perform sling exercises, and then they underwent a four-week experiment. The experimental results of this study were as follows: the VAS and KODI showed a statistically significant difference (P<.05) and a larger effect size within each group after the intervention, it exhibited no statistically significant difference between the two groups (P>.05). There were significant differences in ST before and after intervention in each group (P<.05), however there was no significant difference between the groups. The present study suggest that the effects of lumbar stabilization exercise and sling exercise are similar.

A karyotype analysis of five wild rose species (Rosa helenae, R. mulliganii, R. multiflora, R. rubus, and R. solieana) was performed using bicolor fluorescence in situ hybridization (FISH). All five species were found to be diploid (2n = 2x = 14). The chromosome length in the metaphase stage ranged from 1.29 to 2.05 μm in R. helenae, 3.32 to 6.82 μm in R. mulliganii, 1.58 to 2.24 μm in R. multiflora, 2.05 to 3.46 μm in R. rubus, and 1.62 to 2.46 μm in R. solieana. The chromosomes were either metacentric or submetacentric, with no subtelocentric or telocentric chromosomes being observed. Each p air of 5 S and 4 5S rDNA sites was detected at the proximal region of the long arm and the terminal region of the short arm of chromosome #7, respectively.

This study examined the relationship between reading and vocabulary within general and academic context. Forty-seven Korean EFL university students who participated in this research were given a reading comprehension test of general and academic topics. Also, vocabulary tests were conducted to measure the students’ size of vocabulary and their knowledge of general and academic words. The results revealed different findings for each type of vocabulary and reading. First, learners’ size of vocabulary significantly predicted reading comprehension, but the predictive power of academic vocabulary was stronger than vocabulary size. Second, general reading comprehension showed a similar result with the overall reading comprehension score in that academic vocabulary made a stronger contribution than vocabulary size. Finally, a different result was found for academic reading comprehension, and students’ size of vocabulary rather than academic vocabulary was the only significant predictor. The results indicate the different characteristics of general and academic reading, which implicates that each type of reading should be taught in a different manner.

The study investigates the relative effects of two types of indirect written corrective feedback (CF) on the acquisition of English articles. Thirty-five high intermediate Korean EFL college students who were enrolled in three composition classes participated in this study. After the instruction on the English article usage, three classes (Class A, Class B, and Class C) received different types of feedback on their blog writings over the course of a semester. Both Class A and Class B received indirect feedback in the form of underlining errors. In the following class, Class A received correct forms with metalinguistic information for the errors revised incorrectly, but Class B did not have such opportunities. The Class C received no feedback. The results showed that only Class A, which received indirect feedback plus correct forms with metalinguistic information, made a statistically significant gain from the 3 sessions of feedback treatment. Pedagogical implications were provided on the basis of the findings.
