임희정,이영희 한국기상학회 2019 대기 Vol.29 No.1

The characteristics of the sea breeze were investigated using the wind and temperature data collected from 300-m tower at Boseong from May 2014 to April 2018. Sea breeze day was detected using following criteria: 1) the presence of a clear change in wind direction near sunrise (between 1 hour after sunrise and 5 hours before sunset) and sunset (from 1500 LST to midnight), 2) presence of thermal forcing of sea breeze and 3) no heavy precipitation (rain < 10 mm d−1). Sea breeze days occurred on 569 days for 4 years. The monthly distribution of sea breeze day occurrence shows maxima in May and September and minimum in December. The average onset and cessation times of the sea breeze are 0942 LST and 1802 LST, respectively. Although the 10-m wind shows clockwise rotation with time in the afternoon, the observed hodograph does not show an ideal elliptical shape and has different characteristics depending on the upper synoptic wind direction. Vertical structure of sea breeze shows local maximum of wind speed and local minimum of virtual potential temperature at 40 m in the afternoon for most synoptic conditions except for southeasterly synoptic wind (60o~150o) which is in the same direction as onshore flow. The local minimum of temperature is due to cold advection by sea breeze. During daytime, the intensity of inversion layer above 40 m is strongest in westerly synoptic wind (240o~330o) which is in the opposite direction to onshore flow.

임희정,박근호,송준호,이승원,조형찬,이승우,한지영,김문재 대한신장학회 2005 Kidney Research and Clinical Practice Vol.24 No.4

Purpose:Urinary N-acetyl-β-D-glucosaminidase (NAG) has been known to reflect the damage of proximal tubular cells in the early stages of renal disease. Recent studies have demonstrated that tubular grade predicted renal outcome better than did other histological parameters in IgA nephropathy. We evaluated the meaning of urinary NAG in relation with initial histological features and renal outcomes in early subclinical IgA nephropathy. Methods:Among the firstly diagnosed IgA nephropathy patients from Jan 2001 to Dec 2002, 43 subjects were selected with the criteria of normal renal function and 24-h urinary protein excretion <3.5 g/day. The subjects were followed for 2 years. Pathologic lesion was graded according to HASS classification and semiquantitative scorings, from 0 to 3, were carried out for glomerular (GG), interstitial (IG), tubular (TG), and vascular (VG) lesion. Results:The subjects consisted of 20 male and 23 female with mean age of 30±13 years, baseline blood pressure 116±15/74±10 mmHg, Cr 1.03±0.24 mg/dL, Ccr 88±19 mL/min, 24-h urinary protein excretion (UPER) 1,790±1,610 mg/24-h, urinary NAG 11.8±11.0 U/g cr at the time of biopsy. Hass subclass was correlated significantly with glomerular, tubular, and interstitial grades (all p<0.05). In comparison with clinical parameters, glomerular grade was significantly related with 24-h UPER (p<0.05) and tubular grade was significantly related with systolic blood pressure (p<0.05). Urinary NAG level at the time of biopsy show significant correlation with tubular grade (p<0.05). Progression of renal disease occurred in nine patients (20.9%). The patients with renal disease progression showed significantly low baseline Ccr, high 24-h UPER, and high NAG (all p<0.05). In pathological findings, tubular grade was significantly related with renal prognosis (p<0.05). In regression analysis, tubular grade was a independent predictor of renal prognosis among above four parameters showing significant differences. In survival analysis, tubular grade 0, 1 and grade 2, 3 showed significant difference in renal survival as compared to each other. The patients with baseline NAG urinary NAG above 10 U/g Cr showed significantly worse renal survival as compared with those below 10 U/g Cr (p<0.05). Conclusion:Tubular lesion is an independent factor associated with renal progression in these patients. Urinary NAG reflects well the degree of tubular lesion at the time of biopsy. We carefully suggest, therefore, that the measurement of urinary NAG level is helpful to estimate tubular lesion and predict renal prognosis in subclinical asymptomatic IgA nephropathy patients before they undergo renal biopsy. 목 적:IgA 신증의 예후 예측에 있어서 진단 당시의 신세뇨관 병변이 중요한 인자임이 최근 밝혀지고 있다. 신질환의 초기에 urinary N-acetyl-β-D-glucosaminidase (NAG)는 근위세뇨관 세포의 손상을 잘 반영하는 것으로 알려져 있다. 저자들은 경증 IgA 신증 환자에 있어 조직학적 소견과 NAG치가 신질환의 경과와 어떤 관계를 가지는가를 관찰하였다. 방 법:2001년 1월부터 2002년 12월까지 IgA 신증을 처음 진단 받은 환자 중에서, 진단 당시 신기능이 정상이고 24시간 단백뇨가 3.5 g 미만인 환자 43명을 대상으로 신조직 검사 및 요 NAG를 측정하였고 2년간 신기능 악화 여부를 추적 관찰하였다. 조직학적 손상도는 기존 문헌을 참조하여 사구체, 신세뇨관, 간질, 혈관 손상도를 grading 하여 분석하였다. 결 과:환자의 평균 연령 30±13세, 남녀비 20:23, 평균 혈압 116±15/74±10 mmHg, 기저 크레아티닌 1.03±0.24 mg/dL, 크레아티닌 청소율 88±19 mL/min, 24시간 요 단백량 1,790±1,610 mg/day, 평균 NAG 11.8±11.0 U/g Cr였다. 사구체 손상도, 신세뇨관 손상도 및 간질 손상도는 Haas 분류와 통계적 연관성이 있었다 (all p<0.05). 사구체 손상도는 24시간 단백뇨와 (p<0.05), 신세뇨관 손상도는 수축기 혈압과 통계적 연관성이 있었다 (p<0.05). 신조직 검사 당시 요 NAG는 Hass subclass 및 세뇨관 손상도와 유의한 연관을 보였다 (p<0.05). 2년간 신기능 악화는 총 9명 (20.9%)의 환자에서 발생하였다. 신기능 악화군은 진단시의 크레아티닌 청소율이 유의하게 낮았고, 24시간 단백뇨, NAG가 유의하게 높았으며, 조직학적 소견에서는 신세뇨관 손상도가 신기능의 악화와 관련이 있는 것으로 나타났다 (all p<0.05). 회귀분석에 의하면 신세뇨관 손상도가 신기능 악화의 독립적 예측 인자로 나타났다. 생존 분석에 의하면 세뇨관 손상 중 등급 0, 1점 그리고 등급 2점, 3점이 서로 신기능 악화률의 유의한 차이를 보였고, 진단 당시 요 NAG치 10 U/g Cr 이상인 환자와 이하인 환자는 서로 유의한 신 생존율의 차이를 보였다 (p<0.05).

In addition, we suggest emergency treatment knowledge for develop substantive education program applicable to clinical as required data. Methods: This subjects were 259 dental hygienists working in dental setting Seoul, Gyeonggi-do from June 5 to July 20, 2016. We analyzed the data with frequency analysis, descriptive statistics, t-test, one-way ANOVA, pearson correlation coefficient, regression analysis by using SPSS. Results: Emergencies experienced by a dental hygienist in dental practice were fainting, local anesthetic allergies, and seizures. As a result of comparing the first aid knowledge, self-confidence, coping ability according to general characteristics of the study subjects, university graduation was higher than college and 3~5 years of working experience showed higher self confidence(F=3.837, p=0.023). The performance of self confidence and coping ability according to the characteristics of first aid showed high results in first aid training and dental hygienist having CPR license. Based on multiple regression analysis, confidence about emergency treatment is the biggest impact on coping ability(p<0.05). Conclusions: Dental hygienists need to develop and provide programs that can improve the ability of dental hygienists to respond appropriately and promptly in case of emergencies by recognizing the importance of first aid through conservative education.

멀티미디어를 활용한 수준별 초등영어 수업활동 개발 연구: 5, 6학년 내용을 중심으로

임희정 한국중앙영어영문학회 2008 영어영문학연구 Vol.50 No.3

The main themes of the tentative 2006 Primary English Curriculum still maintains learner centeredness, emphasizing teaching based on students' language level. Even though the importance of teaching by level has been recognized, its implementation has not effectively progressed. In addition, the criteria for developing activities by students' language level have not been clearly defined. Thus, this study aims to develop differentiated multimedia-assisted English classroom activities for 5th and 6th graders in elementary school. In order to accomplish this purpose, the current activities for 5th and 6th graders were analyzed and found to be focused mainly on speaking skills; criteria for developing differentiated multimedia-assisted English classroom activities were then developed as a result of synthesizing three elements: language, task, and multimedia. For further research, the newly developed activities should be implemented to investigate how they are applicable to the classroom

The Relationship between Subclinical Thyroid Disease and Cardiovascular Disease Risk Score in Koreans

임희정,안성희,홍성빈,서영주 대한의학회 2017 Journal of Korean medical science Vol.32 No.10

Subclinical hyperthyroidism and subclinical hypothyroidism are characterized by abnormal thyroid stimulating hormone (TSH) with normal free thyroxine. Subclinical thyroid diseases, to date, have received less attention compared with other thyroid diseases since they are asymptomatic. This study aimed to verify the association between subclinical thyroid diseases and cardiovascular diseases (CVDs) risk score in the Korean population. This was a population-based cohort study using data collected from 3,722 subjects (aged ≥ 30 years) during the 6th Korea National Health and Nutrition Examination Survey (KNHANES VI; 2013–2015). Gender-specific Framingham risk scores were calculated to identify the association between subclinical thyroid diseases and 10-year CVD risk score. Complex survey, with consideration of sampling weight, was analyzed using generalized linear models after stratification by gender. The TSH reference range was between 0.61 and 6.91 mIU/L in this study. TSH showed a positive association with the 10-year CVD risk score only in the female population (P = 0.001). There were significant differences in the least squares means of 10-year CVD risk score by the effect of subclinical hypothyroidism compared with euthyroidism (normal group) in females, after adjusting for body mass index, white blood cell, and urine iodine (P = 0.006 and Bonferroni corrected P = 0.012). In conclusion, subclinical hypothyroidism is associated with increased 10-year CVD risk score in the female Korean population aged 30 years or more. Therefore, we recommend to clinically checkup major CVD risk factors in female patients with subclinical hypothyroidism aged 30 years or more.

임희정 한국여성정책연구원 2011 여성연구 Vol.79 No.-

In Korea, women's career mobility are likely to be different from those of men. This study, therefore, discusses the comparison of career mobility between male and female employees, and analyzes the effect on women‘s upward career mobility, using the data of the Human Capital Corporate Panel(HCCP) study(KRIVET, 2010). A total of 1,818 women and 8,455 men were used for the final analysis. The results of this study are as follows: First, human capital variables such as educational level and tenure have a positive effect on upward career mobility for both men and women. Second, marital status has a different effect on men and women's career mobility. Married women have the lower managerial success than single women. On the other hand,married men have the higher managerial success than single men. Finally,opportunities as to training and development have a significant impact on career mobility for both men and women. And this study has supported that formal bidding system play a role of making women's upward career mobility, but has no effect on men's upward career mobility. On the other hand, management by objectives(MBO) has no effect on men and women's upward career mobility. 조직내 경력개발, 경력성공과 관련하여 연구가 많이 진행된 반면에 경력이동의 개념을 직접적으로 다룬 연구는 많지 않으며 특히 국내연구는 미흡하다고 볼 수 있다. 그 이유로는 경력이동에 대한 개념 정의가 연구자마다상이하며 경력이동을 측정할 수 있는 척도 역시 다양하기 때문이다. 따라서본 연구에서는 경력이동 중에서 수직적 경력이동에 초점을 두어 접근하고있으며 이러한 수직적 경력이동에 있어서 남녀간에 차이가 있는지, 있다면여성이 남성보다 열세인 이유는 무엇인지, 실제적으로 여성근로자의 수직적 경력이동에 영향을 미치는 요인에 관해 분석하였다. 이를 위해 직업능력개발원의 「인적자본기업패널조사」의 3차 패널자료를 사용하여 여성 1,818명, 남성 8,455명을 분석하였다. 분석결과, 인적자본 변수인 교육수준과 근속년수의 경우 여성과 남성의수직적 경력이동에 긍정적 영향을 미치는 것으로 나타났다. 한편, 개인상황변수인 혼인상태가 수직적 경력이동에 미치는 영향은 남녀간에 뚜렷한 차이를 보였다. 여성은 미혼자에 비해 기혼자가 수직적 경력이동이 더딘 반면에 남성은 기혼자가 미혼자보다 수직적 경력이동이 빠른 것으로 나타났다. 또한, 인사관리 변수인 교육 및 훈련 기회는 여성과 남성의 수직적 경력이동에 긍정적으로 유의한 영향을 미치는 것으로 나타났으며 그 효과는 여성에게 더 큰 것으로 밝혀졌다. 그러나 사내공모제는 여성의 수직적 경력이동에 긍정적 영향을 미쳤으나 남성에게는 유의한 영향을 주지 않았으며 목표관리제도는 여성과 남성의 수직적 경력이동에 유의한 영향을 주지 않는 것으로 나타났다

Objectives: Republic of Korea has entered an aged society, recently. As chronic diseases increase, elderly inpatients has been increasing and they have used caregivers for convenience. Accordingly, this study aims to investigate the oral health knowledge and attitude of caregivers on oral health management of elderly inpatients, which would affect the general health and quality of life. Methods: A survey questionnaire was distributed to the caregiver(n=165), at a neurosurgery or orthopedic hospital inpatient ward in Seoul, Gyeonggi-do from April 1 to 14, 2017. We analyzed the data with descriptive statistics analysis, chi-squared analysis and logistic regression analysis by using SPSS 23.0. Results: The response rate to the questionnaire was 92%. Oral health management provided by caregivers to inpatients in the elderly was prevention of oral diseases(92.8%), tooth brushing (89.5%), use of oral care products(68.4%), denture cleaning(90.8%) and oral cleaning(90.8%). Frequency analysis of oral health management in accordance with the educational needs of caregivers was all confirmed statistically significant(p<0.05). In the logistics regression model, oral health knowledge was significantly associated with low oral cleaning(OR=1.58) and oral health attitude was significantly associated with high denture cleaning(OR=1.29) and oral cleaning(OR=1.28) after adjustment for other covariates including gender, age, certification, education level, ward, working years. Conclusions: It is necessary to expand the scope and improve the quality of education that can change the attitudes and behaviors of the caregivers on the oral health management of the elderly on the basis of the current oral health education.

This study aimed to analyze the preoperative factors of immature first molars treated with vital pulp therapy and to find out their correlation in pediatric patients. From May 2014 to January 2020, 523 patients and 1,242 immature first molars were investigated. Factors including age, sex, tooth location, Molar-incisor hypomineralization (MIH), caries cavity location, and history of previous restoration were evaluated. As a result of the study, the vital pulp therapy group had 5.56 times more MIH, 3.39 times more mesial cavities, and 8.73 times more distal cavities. In order to avoid vital pulp therapy in immature first molar, early diagnosis and active management of MIH and preventive treatment of mesial and distal caries are necessary after its immediate eruption.
