Oral examination ensures early detection and treatment of oral diseases and improvement of quality of health-related life. This is imperative as it reduces individuals' dental medical expenses and social costs caused by diseases. However, as the low oral examination acceptance rate continues to be a problem, this study was conducted to identify the factors that influence the oral examination of an economically active population. In this study, 4,836 economically active individuals between the ages of 20 and 65 years were studied using data from the 7th National Health and Nutrition Survey in 2018. Logistic regression analysis was performed to determine the factors influencing demographic and sociological characteristics on oral examination after adjusting for complaints of mastication and speech discomfort. As a result of confirming the factors influencing the oral examination, increase in age tended to be inversely proportional to the oral examination. Income level, type of job, and job position were identified as factors that influenced oral examinations. Compared to the group with a high socioeconomic status, which is represented by a group with a high income level or a stable job type or job position, the group with low economic status was found to have a negative effect on oral examination. Oral management of vulnerable groups, who might not be considered while devising oral health management policies, should be promoted through the development and provision of oral health management policies that consider employment status and environment.

Background: To evaluate the clinicopathologic and demographic characteristics of triple-negative breast cancer (TNBC) patients and to determine differences from non-triple-negative cases. Materials and Methods: A detailed review of the medical records of 882 breast cancer (BC) patients was conducted to obtain information regarding age, menopausal status, height and weight at the time of diagnosis, presence of diabetes or hypertension, and pathologic characteristics of the tumor (tumor size, lymph node status, histologic grade, ER status, PR status, HER2 status, p53 mutation). Body mass index (BMI) was calculated and a value of ${\geq}30$ was considered as indicative of obesity. Results: 14.9% (n=132) of the patients had TNBC. There was no difference among the patients in terms of median age, comorbid conditions and menopausal status. The proportion of medullary, tubular and mucinous carcinomas was significantly higher (15.9%) in the triple-negative (TN) group, while invasive lobular histology was more frequent (8.2%) among non-triple negative (NTN) cases (p<0.001). Grade 3 (G3) tumors were more frequent in the triple-negative group (p<0.001). The rate of p53 mutation was 44.3% in TN tumors versus 28.2% in the NTN group (p<0.001). The two groups were similar in terms of LN metastasis. In the NTN group, the rate of patients with BMI ${\geq}30$ was 53% among postmenopausal patients, while it was 36% among premenopausal women, and the difference was statistically significant (p<0.001). No significant difference was observed in terms of BMI between postmenopausal and premenopausal patients in the TN group (p=0.08). Conclusions: TNBC rates and clinicopathologic characteristics of the Turkish patient population were consistent with the data from Europe and America. However, no relationship between obesity and TNBC was observed in our study. The association between TNBC and obesity needs to be evaluated in a larger patient population.

본 연구의 주된 목적은 IMF 외환위기를 계기로 하여 사회경제적 차별출산의 양상이 어떻게 변화하였는가를 파악하는 것이다. 이 연구에서는 2003년 전국출산력조사 자료를 활용하여 20-49세 기혼 여자의 총출생아수와 1998년 이후의 출생아수에 대한 비교분석이 이루어 졌다. 또한, 분석대상을 1997년 이전에 결혼하였거나 재혼한 부인들과 1997년 이후 처음 결혼한 부인들의 두 집단으로 구분하여 출산력 수준과 출산행태를 비교함으로써 IMF 외환위기 이전과 이후의 변화양상을 파악하고자 시도하였다. 총 출생아수에 대한 분석 결과, 부부의 교육수준, 직업, 종사상 지위 등의 사회경제적인 조건과 출산수준은 대체로 뒤집어진 J 자형의 관계를 유지하는 것으로 밝혀졌다. 즉 사회경제적 지위가 가장 높은 집단은 바로 밑의 집단보다 출산수준이 상대적으로 높았다. 그런데, 최근의 출산수준은 이러한 사회경제적 차별출산과는 뚜렷하게 대조적인 양상을 나타냈다. IMF 외환위기 이후 출산수준 감소의 폭은 기존의 출산수준과 정비례하는 방식으로 이루어졌다. 출산수준이 높은 집단일수록 급속한 출산력 저하가 이루어졌으며, 출산수준이 낮은 집단에서는 상대적으로 변화가 완만하였다. 그 결과, 최근의 출산수준은 중상층에 해당하는 사회경제적 지위를 지닌 집단이 가장 높고 다음이 최상위 집단, 그리고 하위 집단의 순으로 바뀌었다. 이러한 경향은 부부의 교육수준, 직업, 종사상 지위, 주관적 계층에 따른 최근 출산력의 변화양상에서 일관적으로 나타났다.

Objectives: The incidence of cardiovascular disease (CVD) mortality is increasing in developing countries. This study aimed to decompose the socioeconomic inequality of CVD in Iran. Methods: This cross-sectional population-based study was conducted on 20 519 adults who enrolled in the Ardabil Non-Communicable Disease cohort study. Principal component analysis and multivariable logistic regression were used, respectively, to estimate socioeconomic status and to describe the relationships between CVD prevalence and the explanatory variables. The relative concentration index, concentration curve, and Blinder-Oaxaca decomposition model were used to measure and decompose the socioeconomic inequality. Results: The overall age-adjusted prevalence of CVD was 8.4% in northwest Iran. Multivariable logistic regression showed that older adults, overweight or obese adults, and people with hypertension and diabetes were more likely to have CVD. Moreover, people with low economic status were 38% more likely to have CVD than people with high economic status. The prevalence of CVD was mainly concentrated among the poor (concentration index, -0.077: 95% confidence interval, -0.103 to -0.060), and 78.66% of the gap between the poorest and richest groups was attributed to differences in the distribution of the explanatory variables included in the model. Conclusions: The most important factors affecting inequality in CVD were old age, chronic illness (hypertension and diabetes), marital status, and socioeconomic status. This study documented stark inequality in the prevalence of CVD, wherein the poor were more affected than the rich. Therefore, it is necessary to implement policies to monitor, screen, and control CVD in poor people living in northwest Iran.

GENDISCAN study (Gene Discovery for Complex traits in Asian population of Northeast area) was designed to incorporate methodologies which enhance the power to identify genetic variations underlying complex disorders. Use of population isolates as the target population is a unique feather of this study. However, population isolates may have hidden inbreeding structures which can affect the validity of the study. To understand how this issue may affect results of GENDISCAN, we estimated inbreeding coefficients in two study populations in Mongolia. We analyzed the status of Hardy-Weinberg Equilibrium (HWE), polymorphism information contents (PIC), heterozygosity, allelic diversity, and inbreeding coefficients, using 317 and 1,044 STR (short tandem repeat) markers in Orkhontuul and Dashbalbar populations. HWE assumptions were generally met in most markers (88.6% and 94.2% respectively), and single marker PIC ranged between 0.2 and 0.9. Inbreeding coefficients were estimated to be 0.0023 and 0.0021, which are small enough to assure that conventional genetic analysis would work without any specific modification. We concluded that the population isolates used in GENDISCAN study would not present significant inflation of type I errors from inbreeding effects in its gene discovery analysis.

Purpose: The aim of this study is to provide baseline data on the housing environment of a vulnerable population. Methods: This study provides a descriptive survey on the housing environment of a vulnerable population of a city in Gyeong-gi province. A total of 9,061 households were selected as research participants. Data were collected through face-to-face interviews by visiting nurses from February 2014 to March 2014. Results: Interviewees answered "poor" on items including cold drafts, illumination, daylight penetration, inflow of polluted air, house odor, stairs safety, noise, mold, pests, and ventilation. The score for housing environment problems showed a significant group difference due to gender, age, economic status, family type, type of housing, and type of ownership. Conclusion: These results indicate that the vulnerable population is exposed to a poor housing environment. Thus, there is an urgent need to improve the housing environment for the vulnerable population. Based on this study, linking a visiting health care service program and housing environment improvement projects from relevant administrative agencies might be recommended in order to effectively improve the housing environment.

Population ecological characteristics of growth and mortality play an important role in understanding the population dynamics of marine mammals. The instantaneous coefficients of natural and bycatch mortality were estimated for minke whales (Balaenoptera acutorostrata) in Korean waters using a population assessment model composed of bycatch and abundance data. The survivorship curve of this population was fitted to the data, and then the curve was revised using age-specific relative bycatchability coefficients ($q_t$). Instantaneous coefficients of natural and bycatch mortality of minke whales were estimated as 0.024/year and 0.076/year, respectively, and from this the survival rate was estimated as 0.905. This estimated survival rate was comparable to other cetaceans in other regions. The $q_t$ for this population ranged from 0.020 to 0.193. The revised survival rates were higher when the $q_t$ was taken into account. The mortality coefficient, survival rate, $q_t$ and survivorship curves had not previously been determined for minke whale in this area. This estimate could serve as fundamental information to assess the status of this population and for conservation and rational management.

The decrease in population of school age is one of major influencing factor of transformative educational environment. After the nineteen eighties, the population of South Korea has increased step by step, but the population of school age has been decreasing rapidly by low birth rate. As a result, closed school by merger and abolition of small school occurred all over the country. The closed school needed effective function as center of local community. Consequently the purpose of this study is to provide basic data for effective policy making of closed school by comparative analysis of educational environment such as number of students, schools, students per class, status of usage of closed school of the east area and the west area divided by The Tae Baek Mountains in the Gangwon-do, which has the least students in the nationwide. The results of this study are summarized as follows: 1) Gangwon-do has high decreasing rate of population, schools and students compared with other provinces. However it has significantly low number of students per class. 2) The number of students, schools of the west area in Gangwon-do outnumbers that of the east area. However the number of students per class of the east area in Gangwon-do lesser than that of the west area.

노화란 인간을 포함한 모든 생물이 죽음을 향해서 변화해가는 과정을 포괄적으로 말한 것으로 사람들은 위의 과정을 일생이라 정의하는데, 이를 세분하여 성장, 성숙 또는 유지, 노화로 나누어 볼 수 있다. 이러한 입장에서 보면 노화는 초기 성장단계로부터 연계되고 또한 노화이전의 결과가 노화로 나타난다고 말 할 수 있다. 올해는 유엔이 정한 노인의 해이다. 과학의 발전과 경제적 조건의 향상으로 전세계적으로 인간의 평균 수명이 증가하고 있는 추세인데 이로써 65세 이후의 노인의 비율이 각 나라마다 증가하고 있는 경향을 보이고 있다. 따라서 노인들의 건강한 노후를 위해 다각적인 배려가 모색되어야 한다. 이런 입장에서 노인의 건강과 영양섭취 실태에 영향을 미치는 사회 경제적 요인을 문헌을 중심으로 고찰해 보았다. 한국의 경우, 65세 이상의 노인의 비율이 1997년 현재 전 인구의 6.3%로 다른 OECD국가에 비해 노인인구의 비율은 낮지만 평균 수명의 증가로 점차 그 비율이 높아지고 있어 프랑스, 스웨덴과 같이 노인 인구가 10%를 넘는 고령화 국가에는 아직 못 미치지만 점차로 그에 접근해 가고 있는 실정이다. 이런 추세라면 2020년경에는 노인 인구가 아동인구를 앞설 것으로 예측하고 있다. 여러 연구 결과에 의하면 한국의 노인들은 경제적으로 궁핍한 상태에 있는 것으로 나타나고 있는데 이런 경제적인 조건이 노인들의 주관적인 생활 만족도와 건강상태에 영향을 미치는 것으로 보인다. 뿐만 아니라 교육 정도가 높을수록, 가족간의 결속력이 클수록 노인들이 느끼는 주관적 건강 상태가 높아지는 것을 볼 수 있다. 또한 수입, 교육, 직업, 고용상태, 결혼상태, 가족구성원, 성, 어린시절의 조건 등이 노인의 건강과 밀접한 관련을 맺고 있는 것으로 제시되고 있다. 수입의 감소는 노인의 사망률을 증가시키며 결혼 한 경우는 결혼하지 않은 경우보다 사망률이 낮았다. 고용상태와 직업의 경우도 사망률에 영향을 주는데, 고용된 사람의 경우 비고용된 사람의 경우 보다 사망률이 낮았으며 비전문직 종사자보다 전문직 종사자의 사망률이 낮은 것으로 보고되고 있다. 어린 시절의 조건은 노인의 건강에 영향을 미치며 건강에 대한 관심도에 의해 중재될 수 있는데, 노인의 어린 시절에 발생한 가족간의 불화는 건강에 대한 관심도를 낮추어 그후 노인기 건강에 영향을 준다고 한다. IUGR은 신생아의 크기와 모양의 차이를 가져오며 성인기의 상이한 질병을 유발시키므로 태아기의 성장 손상은 성인의 건강에 중요한 영향을 준다. 생활방식은 사회경제적 차에 의한 건강 불평등을 야기시키는 한편, 생활방식의 차는 사회경제적 차에 따른 건강 불평등을 다소 완화시킬 수 있다. 생활방식이 양호한 경우 노인의 자가건강 만족도는 증가된다고 한다. 그러나 생활방식에 의한 영향은 사회경제적 요인에 비해 그 영향이 적다고 한다. 한국노인의 영양섭취상태는 권장량에 비해 부족하다고 보고되고 있으며 수입, 교육, 계층의식 등의 사회경제적 요인에 따라 영양섭취량과 식습관, 우울도 등이 영향을 받는다. 또 도시거주노인에 비해 농촌거주노인이, 재가노인에 비해 시설노인의 영양상태가 부족한 것으로 보고되고 있는데 거주상태에 따라 노인의 건강과 영양상태가 달라지는 것으로 나타나고 있다. 결론적으로 노인들과 연관된 사회경제적 요인은 노인의 건강과 영양상태에 중요한 영향을 미치므로 노인들이 영향을 받고 있는 사회경제적 요인의 복합적인 분석을 통하여 노인의 건강과 영양상태를 보다 효율적으로 증진시킬 수 있는 대안이 마련되어져야 한다고 사료된다.
