윤태림 청주대학교 보건의료과학연구소 2020 보건의료과학연구 Vol.9 No.1

이 연구의 목적은 임상에서 뇌졸중 환자를 치료시 앉은 자세에서의 균형을 평가하기 위한 안정적이고 신뢰할 수 있는 평가 방법이 무엇인지 알아내는 것입니다. 널리 사용되는 5가지 앉은 자세에서의 균형평가중에서, 기능적 앉기 검사(Function in Sitting Test), 트렁크 손상 척도 (Trunk Impairment Scale), 앉은 균형검사(Sitting Balance Scale)은 뇌졸중 환자에게 적용시 매우 우수한 신뢰도와 좋음에서 매우 우수한 정도의 타당도를 보여줬다. 일반적인 상황에서 뇌졸중 환자의 앉은 균형을 측정할 때 이 도구들을 유용하게 사용하는 것이 좋습니다. 수정된 리치 테스트(Modified Functional Reach Test)는 간단한 측정 방법과 우수한 측정자내 신뢰도를 보여 주지만 중간 정도의 타당도를 보여 주었습니다. 따라서 간편한 측정이 요구되는 사항에서 Modified Functional Reach Test의 사용을 고려하는 것이 좋겠습니다. 트렁크 조절 검사(Trunk Control Test)는 상대적으로 다른 측정 도구에 비해 신뢰도와 타당도가 떨어져서 검사의 효용성/정확성이 떨어졌다. 임상가는 앉은 자세 평가 도구들이 각자 고유한 특성을 가지는 것을 이해하고 상황에 따라 유용하게 사용하는 것을 추천합니다.

Cleft lip and palate is the most common malformation in the craniofacial region. The patients with cleft lip and palate have functional problem such as, speech, feeding and respiratory as well as esthetic problem. So, treatment should be done by multidiciplinary team approach. The role of pediatric dentist in the team is advicement for feeding method, guidance of normal growth, caries control and preventive orthodontics. In cleft lip and palate patients, maxillary arch after cheiloplasty is usually collapsed by excessive tension of the scar. This collapse increase the difficulty of later orthodontic treatment. Therefore, the maxillary arch segments should be moved and retaind to normal position as soon as cheiloplasty is done to reduce the need and difficulty of orthodontic treatment. This concept is called by the early orthopedic treatment in cleft lip and palate. Also, this orthopedic appliance works as feeding applince to normal feeding and weight gain We reported two cases of early orthopedic treatment with favorable result in complete bilateral cleft lip and palate patients after cheiloplasty. Patients showed normal weight and their maxillary arch widths were increased.

Lim,Hyun-Sung,Yoon,Tae-Gyeong 한국통합사례관리학회 2021 한국케어매니지먼트연구 Vol.- No.38

This study s purpose was to examine the impact of loneliness, and two types of social support(functional and structural) on the suicidal ideation among elderly living alone. About 254 research participants were recruited from Seoul City and other cities in Gyeonggi-do and finished the questionnaires of loneliness, perceived social support, structural social support, and the suicidal ideation. Data were entered into multiple regression analyses. The finding of this research study indicates that loneliness was an important predictor for suicidal ideation. Thus, increased loneliness was associated with a high level of the suicidal ideation. This research study result showed a moderating effect of functional social support. However, structural social support did not moderate relationship between loneliness and suicidal ideation. This research study would provide implications for social work practices.

윤태호,이용근,임범순,김철위 대한치과기재학회 2001 대한치과재료학회지 Vol.28 No.1

콤포짓트레진의 중합도와 속도는 광원의 종류와 광조사 시간에 따라 영향을 받는다. 현재 할로겐 램프를 중합에 많이 사용하고 있으나 전구의 수명이 짧고, 시간경과에 따라 광선의 출력이 감소하므로 중합도는 낮아져 물성이 감소하고 수복물이 실패할 가능성도 높다. 이를 개선하기 위하여 콤포짓트레진 중합에 사용할 수 있는 LED (blue light emitting diode) 와 플라즈마 아크 기술이 소개되었다. 이 실험에서는 3 종의 광원(할로겐 램프, LED 및 플라즈마 아크) 에서 광조사시간을 달리하여 광에너지의 총량을 변화하는 조건으로 점주도가 서로 다른 3 종의 콤포짓트레진에서 깊이에 따른 중합도를 측정하여 각 광원의 효율성을 상호 비교하였다. 할로겐 램프, LED 및 플라즈마 아크 조사기로 광에너지 총량이 각각 8J/㎤와 16J/㎤ 이 되도록 중합하고 표면에서 1, 2, 3 및 4mm 위치에서 100㎛ 의 두께로 절단하였다. 시편 두께가 50~70㎛ 가 되도록 연마하고 FT-IR 로 표준기선법에 따라 중합직후의 중합도를 측정하였다. 중합방법 및 광조사 부위에서 깊이에 따른 평균 중합도를 계산하여 3 원 분산분석 및 Scheffe 의 방법에 따라 유의수준 0.05 에서 검정하였다. 이 실험에서 다음과 같은 결과를 얻었다. 재료, 깊이 및 광조사 시간 모두 전환율에 유의한 영향을 주었다(p〈0.01). 3 종 광원의 표층에서 1mm 깊이에서의 중합도는 저점도(RVN) 〉중점도(Z25) 〉응축형 콤포짓트레진(SRF) 순이었다(p〈0.05). 3종 광원의 중합도는 유의한 차이를 볼 수 없었다(p〉0.05). 3종의 조사광원 모두에서 광에너지 총량을 2배로 증가한 경우, 중합도는 2mm 깊이까지는 유의한 차이가 없었으나(p〉0.05), 3mm 부터는 광에너지 총량 증가에 따라 유의하게 증가하였다(p〈0.05).

Dental resin composites were introduced commercially in the mid-1960s for the restoration of anterior teeth. Since their advent, resin composites have undergone significant development, which continues to improve the longevity and application of resin composite restorations. Despite the development of new dentin-bonding agents, no system is currently available that completely withstands the formation of contraction gaps at the cementum/dentin-restoration junction, due to the unavoidable polymerization shrinkage of the resin composite during setting, therefore, a major aim of this study was to minimize or control the polymerization shrinkage of composites allowing flow of resin during setting reaction. A thermal dilatometer (DIL 402C, TASC 414/3A Controller, Netzche, Germany) was used to measure and compare conventional continuous cure and pulse cure polymerization shrinkage of seven light curing dental composites and three compomers. For conventional cure, restorative material were polymerized for 2 minutes using VIP (Bisco, U.S.A.) with 400 ㎽/㎠ intensity. After then, further polymerization was allowed for next 12 minutes that total 14 minutes of shrinkage was measured. For pulse cure, material was pre-polymerized irradiating light for 5 seconds with 200 ㎽/㎠ and post-ploymerized 3 minutes later with 400 ㎽/㎠ for 2 minutes. 9 minutes were allowed for further polymerization that total 14 minutes of shrinkage was measured. Polymerization shrinkage ranged from 3.758 ㎛/㎜ (SYC) to 6.897 ㎛/㎜ (P60) for conventional cure and 4.026 ㎛/㎜ (FLT) to 6.996 ㎛/㎜ (SRF) for pulse cure. The highest difference between the two methods was found at EAN (2.713 ㎛/㎜), followed by F20 and CRA which showed significant differences of 2.133, 1.274 ㎛/㎜ respectively (p<0.05). The least difference was found at SYC (0.489 ㎛/㎜). Universal resin composite group showed the highest polymerization shrinkage (6.514±0873 ㎛/㎜), and flowable composite showed the least shrinkage (4.139 ㎛/㎜). Packable composite showed 5.090±1.906 ㎛/㎜, and compomers showed 6.129±2.652 ㎛/㎜.

The purposes of this study were (1) to reexamine what were found by the survey on KNU Teachers College Students after the Pilot School Project (Ⅰ) in order to assess the possibility of .generalizing results of the survey across different groups of students who enter Teachers College after the Pilot School Project was implemented, (2) and to examine students' opinion toward the current procedures of assingning freshemen to departments or majors of the Teachers College. The subjects were freshmen of KNU Teachers' College from 1975 to 1777 academic year. However, the data pertaining to the students from 1975 to 1976 had been gathered while the survey on Teachers College Students after the Pilot School (Ⅰ) was being carried out. In order to collect the data with regard to the students entered the Teachers College in 1977, four different questionnaives were employed. The data were statistically tested by means of chi-technique only when it seemed necessary and appropriate. Major findings of this study are as following: (1) After the Pilot School Project was employed, there were general tendency in students' reason applying for admission to KNU Teachers College: Each academic year, approximately 40% of freshmen decided to enter the college to be secondary school teachers in the future. (2) Students' attitude toward the new procedures of screening college applicants, which was employed after the Pilot School Project, were negative in general. Furthermore, their negative attitude became stronger year by year. (3) The degree of students' satisfaction with their majors were relatively higher than that expressed by the students who entered the college before the Pilot School Project was employed. (4) Both students' criteria for selecting their majors and then reasons for changing their majors which they had been interested in applying were varied across time subjects and time. (5) The obtained contingency coefficient between departments and GPA students of each department earned during thir freshmen year was 0.831. It seems to indicate that majority of freshment tends to choose their majors according to their GPA rather than their interest or aptitude. (6) Approximately 67.73% of freshmen of the 1977 academic year accepted the end of the academic year as the most appropriate time for assigning them to departments they desire to enter. 7) Approximately 52.10% of freshment supported the idea of assigningas many students to the departments as they wish to enter, as far as it is possible, by adjusting the capacity of department, which is regulated by MOE. (8) Approximately 61.08% of freshmen claimed not to deduct their GPA when their first choice of department became impossible and turned down to the second or the third one.
