Gaol, Hye-Won, 2012, A Linear Regressional Analysis of Pith-Its in English, Linguistic Research 29(1), 21-44. Building up on Choi`s (2011) research that identifies the features of the instrument-taking predicates that influence the presence of instrument with-PPs, the current study explores to analyze the BYU-BNC corpus data of instrument with-PPs with a linear regression model. By building a multiple linear regression model which can deal with identified predictor variables simultaneously, this paper tries to explain the frequencies of instrument with-PPs and their nature of argumenthood by combinations of predictor variables. This modeling analysis can be a useful step toward studying gradient argumenthood via a more complex evaluation of a variety of morphological, syntactic, and semantic factors.

Verb class and instrument PPs: A mixed model analysis

( Hye-won Choi ) 경희대학교 언어정보연구소 2017 언어연구 Vol.34 No.2

This paper investigates whether a lexical variance caused by verbs influences the choice and frequency of instrument with-PPs. The corpus data shows that observations grouped by verb class demonstrate systematically different behaviors and this individual variance of verb classes can be captured by means of a random effect of a mixed-effects model. Building up on Choi`s (2012) research that identifies the syntactic, semantic, and morphological factors that influence the presence of instrument with-PPs as fixed effects, the current study classifies the instrument-taking verbs into verb classes, based on Levin`s (1993) study, and builds a mixed-effects model taking verb class as a random variable. The new statistical technique of hierarchical, multi-level, mixed-effects modeling (Baayen 2008; Bresnan et al. 2007; Gelman and Hill 2007; Johnson 2008; Kuperman 2009; Pinheiro and Bates 2000) can process across-word fixed effects and by-word random effects together. By taking into consideration the subtle syntactic and semantic characteristics of verbs, this new modeling analysis provides a way to incorporate native speakers` lexical knowledge into grammar.

Characteristics of a Current‑Limiting DC Circuit Breaker with a Superconducting Coil Applied to the Commutation Circuit

Hye‑Won Choi,Sang‑Yong Park,최효상 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.4

We research team has proposed a current-limiting superconducting DC circuit breaker that combines a High-temperature superconducting wire (HTS) with a DC circuit breaker, and secured its operation performance in our previous study via simulation. In this paper, we designed and produced an actual current-limiting superconducting DC circuit breaker, as well as analyzed its current limiting and breaking performance. In addition, the operation characteristics at diferent lengths of the HTS with increasing voltage were analyzed. The operation reliability of the proposed DC circuit breaker was demonstrated by a simulation system that was built similar to the actual system.

Capturing Lexical Variance with a Mixed Model : Verb in Ordering Variation

Hye-Won Choi 담화·인지언어학회 2010 담화와 인지 Vol.17 No.1

Based on the dative data collected from Sejong Corpus (Kim 2000), Choi (2010) has analyzed the word order variation and proposed a statistical model of logistic regression that identifies all predictive variables that influence word order and predicts which order (between 'dative before accusative' (DA) and 'accusative before dative' (AD)) is more likely to occur, given the predictor variables. Building up on the Choi's (2010) analysis, this paper investigates whether a lexical variance caused by word is also affecting the choice of dative word order. In particular, variation caused by the verbs of dative construction is examined in depth, and verb is indeed proved to be a significant random variable. To capture the new random effect by verbs, as well as the fixed effects identified in Choi (2010), this paper proposes a new mixed model that considers fixed and random effects together (Bresnan et al. 2007, 2008, 2009, Baayen 2008, Johnson 2008). The mixed model turns out to be a more powerful model that secures higher accuracy in its predictions.

Laparoendoscopic single-site surgery (LESS) is helpful if not an evidence of suspicious malignancy in huge adnexa tumors. This approach might be reasonable alternative to conventional laparoscopic surgery. We report two cases with LESS for huge cystic adnexal tumors in whole abdomen. A 58 years old multigravida woman in menopause underwent removal of a huge cystic adnexal mass that occupied her entire abdomen by LESS.(ca.5200ml aspiration) A 15 years old single nulligravida woman had a huge cystic adnexal tumor in whole abdomen reaching to the level of the xyphoid process. A needle through the transumbilical single port was inserted directly under the mass. Subsequently, 8000 ml of cystic fluid was aspirated without spillage.

Objectives : To estimate the economic burden of osteoporotic vertebral fracture (VF) from a societal perspective. Methods : From 2002 to 2004, we identified all National Health Insurance claims records for women ${\geq}50$ years old with a diagnosis of VF. The first 6-months was defined as a "clearance period," such that patients were considered as incident cases if their first claim of fracture was recorded after June 30, 2002. We only included patients with ${\geq}$ one claim of a diagnosis of, or prescription for, osteoporosis over 3 years. For each patient, we cumulated the claims amount for the first visit and for the follow-up treatments for 1 year. The hospital charge data from 4 hospitals were investigated to measure the proportion of the non-covered services. Face-to-face interviews were conducted with 106 patients from the 4 study sites to measure the out-of-pocket spending outside of hospitals. Results : During 2.5 years, 131,453 VF patients were identified. The patients had an average of 3.38 visits, 0.40 admissions and 6.36 inpatient days. The per capita cost was 1,909,690 Won: 71.5% for direct medical costs, 20.6% for direct non-medical costs and 7.9% for indirect costs. The per capita cost increased with increasing age: 1,848,078 Won for those aged 50-64, 2,084,846 Won for 65-74, 2,129,530 Won for 75-84and 2,121,492 Won for those above 84. Conclusions : Exploring the economic burden of osteoporotic VF is expected to motivate to adopt effective treatment options for osteoporosis in order to prevent the incidence of fracture and the consequent costs.

This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

최지현,박혜원 울산대학교 2000 생활과학논문집 Vol.2 No.1

본 연구에서는 보육환경(보육시설 및 교사)이 영아의 사회적 행동에 미치는 영향을 관찰을 통해 조사 분석하였다. 울산광역시에 위치한 8개 보육시설(국·공립 보육시설: 4개, 민간 보육시설: 4개)에서 27-35개월 된 영아 40명을 자유놀이 시간에 교실에서 관찰하였다. 각 영아는 20초 관찰, 10초 기록의 시간표집방법에 의해 총 42회 관찰하였으며, 영아의 사회적 행동은 또래와의 상호작용과 교사와의 상호작용으로 나뉘어졌다. 보육시설 변인 중 보육시설유형, 교사 대 영아 비율, 그리고 교사변인 중 전체경력, 영아반 경력, 결혼여부, 소지자격유형이 영아의 사회적 행동에 유의한 영향을 미치는 것으로 나타났다. This study alms to investigate and analyze how child care environments including facilities and caregiver's characteristics affect on toddlers' social behavior using observational methods. Data were obtained in eight child care centers(four public centers and four private centers) in Ulsan. The average age of toddlers was 31.7 months ranging from 27 months to 35 months. For each toddler forty-two observations were done at free play time in the center through the time sampling method of twenty-second observation and ten-second recording. Among characteristics of the child care facilities, types of facilities, the caregivers and toddlers ratio could predict toddlers' social behavior. Total teaching experience, teaching experience with toddlers class, martial status, certificate types of caregivers also could predict toddlers' social behavior.

최혜영,최영현,이원호,최주수 동의대학교 기초과학연구소 1998 基礎科學硏究論文集 Vol.8 No.1

Methyl methanesulfonate (MMS) was fed to Drosophila melanogaster in order to investigate its toxic capability at developmental and adult stages, and the hereditary effect of toxicity and the potency for induction of sex-linked lethal mutation during the spermatogenesis by the means of an attached-X method. In the control group, the egg to adult viability of D. melanogaster was 95.2%, while 3.5mM and 5.0mM treated groups were 90.0% and 84.1%, respectively. In the case of their progenies (F₁), the viability was 96.9% in the control group, while 3.5mM and 5.0mM treated groups were 54.5% and 1.6%, respectively. Therefore, these differences between two generations show significant physiological toxic effects in the next generation. In the parental generation, the developmental time was calculated 11.05 days in the control group, 12.43 days in 3.5%mM treated group, and 13.23 days in 5.0mM. In the case of F₁it was estimated 10.35 days in the control group, and 11.43 days in 3.5mM treated group. Compared with the control groups in two generation, the developmental time generally delayed as the dose of MMS increased. As to the sex-ratio, there was no differences between the control and MMS treated groups. The toxic values of adult stage showed which increased the frequency of mortality with MMS concentrations. The mortality at 120hr in the control group was 1.67% and it in 0.5mM MMS treated group 3.33%. In 2.5mM MMS treated group, it was 33.3% at 72hr, and it 95% at 120hr. The increase of the morality was shown from 72hr in 4.0mM treated group which was 100% at 96hr. There was the concentration-dependent induction of sex-linked lethal mutation during the spermatogenesis by means of an attached-X method, MMS had more pronounced effect in sperm and spermaid stages in D. melanogaster.

Two farmed young ostrich chicks were applied to pathology laboratory at Chungnam National University. Grossly, one ostrich showed rotated tibiotarsus, the other showed rolled toes. Case 1 ostrich was hypertrophy of fibualis longus and tibial cranialis tendon and gastrocnemius tendon in crus, inflammation of flexor digitorum longus. In histopathological views, myocytes of fiburalis longus were showed hypertrophy and hyperplasia. It is not found any specific feature in X-ray of the case 2 ostrich. Limb deformities were detected frequently in farmed ostrich chicks in 2- to 3 weeks old. Limb deformities were an important cause of mortality in farmed ostrich chicks during the first 10weeks after hatch. Cause of limb deformities were considered a nutrition problem.
