유아의 만족지연행동과 어머니양육태도

김선하 한국아동교육학회 1997 아동교육 Vol.6 No.2

The purpose of Chic study is to investigate the relationships between the delay of gratification behavior of 4 year-old children and their mother's child-rearing attitudes. The main issues to be examined are as follows: l.Are there any relationships between the situation type and the delay of gratification behavior? 2.Are there any relationships between mother's child-rearing attitudes in the assumed situation and the delay of gratification behavior of 4 year-old children. 3.Are there any relation ships between mother's child-rearing attitudes in the real situation and the delay of gratification behavior of 4 year-old children? The subjects of this study were 306 children(149 boys, 157 girls) of 4 year-old and their mothers. To check children's delay of gratification behaviors, the interview method was used in two times. That is, investigators asked all children to make a choice between an immediate-smaller reward and a delayed-larger one in the assumed situation and the real. Their mother's attitudes for child-rearing were measured by MBRI questionnaire. x^2-tests are used for data analysis. The major results of this study were as follows: 1. 9 year-old children's behavior on delay of gratification were found to choose a delayed gratification in the real situation. There were some significant relationships between the delay of gratification & situation type. That is, children who chose delay of gratification behavior- in assumed situation took the same behavior in real situation. 2. When mother-'s child-reau-ing attitudes are on Love-dimentions, their children expressed on the delay of gratification. That is, when mothers have Love & Autonomy altitudes, their children expressed high delay of gratification in two situations. On the other hand, when mothers have hostility & control child rearing attitudes, their children expressed immediate gralificaiion in two situations.

김선하,조민우,옥민수,이상일 대한예방의학회 2017 예방의학회지 Vol.50 No.6

Objectives: This study aimed to explore dimensions in addition to the 5 dimensions of the 5-level EQ-5D version (EQ-5D-5L) that could satisfactorily explain variation in health-related quality of life (HRQoL) in the general population of South Korea. Methods: Domains related to HRQoL were searched through a review of existing HRQoL instruments. Among the 28 potential dimensions, the 5 dimensions of the EQ-5D-5L and 7 additional dimensions (vision, hearing, communication, cognitive function, social relationships, vitality, and sleep) were included. A representative sample of 600 subjects was selected for the survey, which was administered through face-to-face interviews. Subjects were asked to report problems in 12 health dimensions at 5 levels, as well as their self-rated health status using the EuroQol visual analogue scale (EQ-VAS) and a 5-point Likert scale. Among subjects who reported no problems for any of the parameters in the EQ-5D-5L, we analyzed the frequencies of problems in the additional dimensions. A linear regression model with the EQ-VAS as the dependent variable was performed to identify additional significant dimensions. Results: Among respondents who reported full health on the EQ-5D-5L (n=365), 32% reported a problem for at least 1 additional dimension, and 14% reported worse than moderate self-rated health. Regression analysis revealed a R2 of 0.228 for the original EQ-5D-5L dimensions, 0.200 for the new dimensions, and 0.263 for the 12 dimensions together. Among the added dimensions, vitality and sleep were significantly associated with EQ-VAS scores. Conclusions: This study identified significant dimensions for assessing self-rated health among members of the general public, in addition to the 5 dimensions of the EQ-5D-5L. These dimensions could be considered for inclusion in a new preference-based instrument or for developing a country-specific HRQoL instrument.

Investigation of xV2O5-B2O3 and xV2O5-B2O3-yNa2O Glassesby 11B MAS NMR

김선하,한옥희,송선기,강재필 한국자기공명학회 2005 Journal of the Korean Magnetic Resonance Society Vol.9 No.1

11B MAS NMR spectra of binary glass system xV2O5-B2O3 and ternary glass system xV2O5-B2O3-yNa2O (x = V2O5 mol%/B2O3 mol%, y = Na2O mol%/B2O3 mol%) were acquired. BO3 units are dominant components in the spectra of xV2O5-B2O3 glass systems while both BO3 and BO4 units appear in comparable amounts in the spectra of xV2O5-B2O3-yNa2O glass systems. More BO3 units were monitored for higher V2O5 contents while more BO4 units for higher Na2O contents. Quadrupole parameters such as e2qQ and η obtained from spectral simulation indicate that e2qQ has a maximum value at x = y = 1 and η decreases and increases as x or y grows, respectively. Our results suggest that V2O5 and Na2O play opposite roles in the ternary glasses. 영어논문

20대 한국인의 미각선호도 및 전구강미각검사법에 의한 미각역치의 측정

김선하,장성용,최재갑 대한안면통증∙구강내과학회 2003 Journal of Oral Medicine and Pain Vol.28 No.4

The authors measured taste preference for sweet, pungent, salty, and sour taste with a 9-point scale and also measured taste detection and recognition thresholds for sucrose, sodium chloride, citric acid, and quinine HCl with the whole-mouth gustatory test method for the 203 healthy male and female Korean subjects who are in the age of the third decade. The 'spray-and-swallow method' was used to stimulate oral taste receptors instead of using the conventional 'sip-and-spit method'. The results were as follows; 1. The whole-mouth gustatory test procedure using 'spray-and-swallow method' may be useful for evaluating gustatory function clinically. 2. The mean recognition thresholds for 4 basic tastes were 0.015982 M solutioin of sucrose for sweet taste, 0.021784 M solution of sucrose for salty taste, 0.000835 M solution of citric acid for sour taste, and 0.0000292 M solution of quinine HCl for bitter taste. 3. The recognition thresholds for 4 basic tastes were higher in male subjects than female subjects 4. The male subjects showed higher taste preference for salty taste than female subjects. Otherwise, there was no difference in taste preference between male and female subjects. 5. There was no consistent relationships between taste threshold and taste preference.

Study on Solution Assembly of P3HT-based Graft Copolymer to Minutely Regulate the Crystallinity and Nanowire Growth

김선하,김영권,김형준,김진성,김범준 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.1

Solution assembly of conjugated polymer based rod-coil copolymers can provide an effective means to produce nanowire (NW) structures. Herein, we investigate the effect of architectural design of corona blocks on the NW formation by using rod-coil “graft” copolymers. A series of poly(3-hexylthiophene)-graft-poly(2-vinylpyridine) (P3HT-g-P2VP) copolymer was prepared with two controlled architectural parameters: grafting fraction (f_g) and molecular weight of P2VP (M_n,P2VP). Grafting P2VP chains gave rise to a steric hindrance and stretching penalty during crystallization, leading to the distinctive structure of NWs, in which their lengths and degree of curvatures were regulated depending on f_g and M_{n, P2VP}. In particular, the f_g affected the crystallinity and self-assembly behaviors. Therefore, we demonstrate that graft architectures of the conjugated rod-coil copolymers can provide a promising tailorbility in the solution-assembled nanostructures suitable for various applications.

하악 전치부에 발생한 치근낭종의 치험례

김선하,최성철,박재홍,김광철 大韓小兒齒科學會 2012 大韓小兒齒科學會誌 Vol.39 No.1

치근낭은 가장 흔한 치성기원 낭으로 치수감염, 치수실활, 외상으로 인한 이차감염 또는 치아 우식에 의해 발생한다. 보통 치근낭은 무증상이나 이차 감염이 발생할 경우 통증, 부종, 발적 등을 유발할 수 있으며, 크기가 커질수록 치근낭은 인접한 신 경을 압박하여 안면비대칭 또는 마비증세를 일으킬 수 있다. 치료는 보존적 신경치료 또는 외과적 처치를 요하며, 낭의 크기 가 크거나 인접 조직의 침범을 야기할 가능성이 있는 경우에는 낭적출술을 시행해야 한다. 대부분의 증례에서 완벽한 치료가 가능하고 재발율이 낮다. 본 증례의 환아들은 하악전치부 낭을 주소로 내원하여 임상검사에서 일부 하악전치가 괴사되었음을 발견하였으므로 근관 치료를 시행한 후 전신마취하에 치근단절제술 및 치근낭 적출술을 시행하였다. 이후 컴퓨터단층촬영을 시행하여 이환부의 골 생성 및 재발여부를 관찰하였으며 성공적인 결과를 보였기에 이를 보고하는 바이다. The radicular cyst is the most common odontogenic cyst which is caused by pulpal inflammation, pulp death, and secondary to trauma or dental caries. Usually, the radicular cyst is asymptomatic, but a secondary inflammation can cause pain, swelling and redness. Getting larger, the radicular cyst can cause facial asymmetry and paresthesia by pressure on nerves. It requires conservative endodontic treatment or surgical approach. When the size of cyst is large or invasion of the adjacent tissue is not expected, cyst enucleation is carried out. And most of the case can be completely cured and shows low recurrence. In these radicular cysts cases, by cyst enucleation or apicoectomy after root canal treatment simultaneously, the infected teeth can be preserved successfully.

Objectives : To evaluate the association between body mass index (BMI) and hemorrhagic stroke. Methods : A case-control study was conducted on 2,712 persons (904 cases, 904 hospital controls, and 904 community controls) participating in an Acute Brain Bleeding Analysis study from October 2002 to March 2004. Two controls for each case were matched according to age and gender. The information was obtained by trained interviewers using standardized questionnaire. A conditional logistic regression model was used to estimate the association between BMI and the frequency of having a hemorrhagic stroke. Results : Obese men (25.0 $\leq$ BMI < $30.0\;kg/m^2$) had an odds ratios (OR) of 1.39 (95% CI 1.03 to 1.87) a hemorrhagic stroke, compared to men with a normal BMI (18.5 to $24.9\;kg/m^2$). Conversely, women with lower BMI had a higher risk of having hemorrhagic stroke. With respect to subtypes of hemorrahagic stroke, we observed about a three-fold increase in the risk of intracerebral hemorrhage (ICH) in the highly obese group. However, these trends were not significant in patients with subarachnoid hemorrhages. Conclusions : Obesity was identified as one of the risk factors in hemorrhagic stroke, in particular ICH. Conversely, in women, a lean body weight increases the risk of hemorrhagic stroke. Consequently, managing one's weight is essential to reduce the risks of hemorrhagic stroke.
