The purpose of this study was to investigate the effects of metabolic syndrome(MS) on quality of life(QoL) using the Korea National Health and Nutrition Examination Survey of 2013. We analyzed data for 4,890 adults, aged 19 year or older and provided the correct data about MS and QoL. MS was defined by the National Cholesterol Education Program-Adult Treatment Panel III with Korea-specific waist circumference cutoffs and QoL was measured by the EuroQol 5-dimension(EQ-5D). The prevalence of MS was 22.1% and high density lipoprotein(HDL)-cholesterol was the highest prevalence in MS components. The mean of EQ-5D index was significantly lower in subject with MS compared to subjects without MS. Among MS components, only higher waist circumference led to EQ-5D index decreasing and the regression coefficient was -0.018. In conclusion, we suggest the attention to QoL and intervention program for improving the QoL in subjects with MS.

AISI 316L 스테인리스강에 새롭게 디자인한 서로 다른 3가지 응고모드를 가진 와이어로 FCAW(Flux Cored Arc Welding)을 하였다. 각각의 3가지 와이어는 Pseudobinary phase diagram에 따라 AF, FA, F모드를 가졌다. 미세조직은 $Cr_{eq}/Ni_{eq}$이 증가할수록 델타 페라이트 함량이 증가하였으며, 초정 상의 경우 초정 오스테나이트에서 초정 페라이트로 변태하였고, 연성저하균열의 민감도가 감소하였다. 연성저하균열은 이동결정립계의 형상에 따라 좌우되며, 미량의 페라이트를 함유한 오스테나이트에서는 페라이트가 핀(Pin) 역할을 제대로 하지 못하여 직선형태의 이동 결정립계 따라 입계 미끄러짐의 메커니즘을 통해 전파되었으며, 곡선형태의 이동 결정립계에서는 델타 페라이트가 핀 역할을 하여 역할을 하여 구속 상태에서 응력집중을 막고 응력을 분산시켜 균열이 전파되는 것을 방해하여 균열이 발생되지 않았다.

Objective : To determine the quality of life and cost consequences for deaf adults who received a cochlear implant. Methods : The data from 11 patients, post-lingual deaf adults who received cochlear implants from 1990 to 2002, underwent cost-utility analysis. The average age of the participants was 49.6 years. The main outcomes were direct cost per quality-adjusted life-year (QALY) using the visual analog scale (VAS), health utility index (HUI), EuroQol (EQ-5D), and quality well-being (QWB), with costs and utilities being discounted 3% annually. Results : Recipients had an average of 5.6 years of implant use. Mean VAS scores increased by 0.33, from 0.27 before implantation to 0.60 at survey. HUI scores increased by 0.36, from 0.29 to 0.65, EQ-5D scores increased by 0.26, from 0.52 to 0.78, and QWB scores increased by 0.16, from 0.45 to 0.61. Discounted direct costs were $22,320, yielding $19,223/QALY using VAS, $17,387/QALY using HUI, $24,604/QALY using EQ-5D, and $40,474/QALY using QWB. Cost-utility ratios using VAS, HUI, and EQ-5D were all below $25,000 per QALY, except using QWB. Conclusion : Cochlear implants in post-lingual deaf adult have a positive effect on quality of life at reasonable direct costs and appear to produce a net saving to society.

Objectives : The purposes of this study were to examine the health-related quality of life(HRQoL) and to identify its related factors for a group of rural adults. Methods : The study subjects were 1,901 adults who were aged 40-70 years and who were living in Naju City, Jeollanamdo. The sociodemographic characteristics, health-related behavior, health status and global self-rated health were collected for statistical analysis. The health-related quality of life was measured by the Euroqol EQ-5D instrument. The differences on the EQ-5D index between the groups were assessed with t-test, ANOVA and hierarchical multiple regression analysis. Results : Overall, the mean value of the EQ-5D index was $0.884{\pm}0.140$ and this score was significantly different according to the socioeconomic characteristics, the health-related behavior, the health status and the global self-rated health. According to the results from the hierarchical multiple regression analysis, the HRQoL was significantly reduced for females, older subjects, and other subjects with no spouse and the subjects with osteoporosis, obesity, mental distress or poorer global self-rated health. Conclusions : The HRQoL for rural adults was related to the socioeconomic characteristics, the health status and the global self-rated health, A better understanding of the factors related to the HRQoL would help to improve the rural adults' quality of life.

In order to develop technology for an equipment qualification (EQ) test, which is an important process in localizing solenoid-operated valves used in nuclear power plants, we analyzed related regulations, test procedures, conditions, equipment, and acceptance criteria. EQ regulations for the solenoid-operated valve are classified as law, guide, and standard, and are subdivided according to test specimens and contents. The EQ test is composed of functional, normal-, and accident- condition tests. The solenoid-operated valve is aged under normal and accident conditions, which are predicted in the design conditions of a nuclear power plant, and the performance of the valve is measured by a functional test. The test method and procedure analyzed in this paper might be very useful for manufacturers as well as EQ testers.

Purpose : The purpose of this study was to examine the self-rated oral health status of local residents and their quality of life in urban and county areas in an effort to provide information on how to improve their quality of life. Method : The 2015 community health survey data for South Gyeongsang Province(10 urban regions and 10 county areas) were analyzed. Result : The findings of the study were as follows: As for the characteristics of self- rated oral health, there were better self-rated oral health, less chewing difficulty, less use of dentures, higher rate of receiving dental checkups and more scaling experience in the urban communities than in the county areas. Concerning EQ-5D and happiness index by region, the two were higher in the urban regions than in the county areas. In regard to EQ-5D and happiness index by the characteristics of self-rated oral health, better self-rated oral health status and less chewing difficulty led to higher EQ-5D and higher happiness index. And the two were higher when dentures were not used, when more dental checkups were received and when there was more scaling experience. Conclusion : Therefore in order to boost the quality of life of local residents, the preparation of various educational programs is necessary to raise their awareness of health, and they should be provided with a wide range of medical benefits by dispersing medical institutions that are mostly located in urban communities or by expanding public health services in county areas.

This paper proposes a new method for fast graphic visualization of accurate frequency response of audio equalizer (EQ). When a logarithmic frequency scale is used, a frequency response in high resolution is required for accurate low-band frequency response. However, the high-resolution frequency response requires a huge amount of computational load, which makes the real-time graphic visualization of frequency response impossible. In order to solve the problem of computational load, the proposed method utilizes a low-resolution virtual frequency response in the mid band. It first computes the virtual frequency response of each filter of EQ in the mid band, and then moves it to the target band so that the result corresponds to the desired filter response. Then, it determines the final frequency response of EQ by combining all filter responses. The experiments confirm that the proposed method provides the frequency response of EQ which has an equivalent shape to that computed in high frequency resolution with huge computational load.

$Na^{+}$는 체내에서 세포외액 (extracellular fluid)의 주요 양이온으로 세포내액과 세포외액은 세포막을 사이에 두고 $Na^{+}$와 $K^{+}$의 높은 농도의 차이를 유지하고 있다. 이러한 농도차이는 세포막에 있는 $Na^{+}$-K$^{+}$ATP ase의 활동에 의하여 유지되며 $Na^{+}$는 체액의 osmolarity와 혈장의 부피 유지, 신경흥분, 근육수축 및 영양소등의 이동에도 중요한 역할을 한다. 체내의 Na balance는 renin-aldosterone system에 의하여 신장에서의 배설조절로 이루어지며, 최근 Na대사에 관여하는 natriuretic hormone이 발견되고 있다. Na의 과잉섭취는 역학적 연구와 동물실험에서 고혈압의 유발인자로 제시되고 있으나, 임상적 연구에서는 Na제한이 혈압강하효과가 있다는 보고와 없다는 보고가 있어 결과가 뚜렷하지 않다. 이는 고혈압 환자중에는 salt-sensitive한 group자 salt-resistant group이 있다는 것과 산업화된 사회들의 Na 섭취량이 이미 너무 높은 수준으로 Na섭취증가와 혈압상승간의 관계를 현재의 연구 방법들로는 찾아내기 어렵다는 ‘saturation effect’로 설명한다. 그러나 Na섭취를 1일 70~100mEq.(NaCl 4.0~5.8g)이하로 줄이면 고혈압 발생이 현저히 감소하고 Na 섭취량이 1일 30mEq.(NaCl 1.7g)이하이면 고혈압은 거의 발생하지 않는다. 그러나 Na섭취가 1일 400mEq.(NaCl 23.2g)이상이 되더라도 인구 중 50~80%는 고혈압에 걸리지 않아 고혈압의 발생은 유전적 인자, 신장 기능의 부족에 의해 지배되고, Na이외에도 K, Ca등의 식이 인자 및 stress, 운동등의 환경적 요인들이 영향을 미친다. Na 섭취량은 자연식품에 들어있는 양 뿐 아니라, 가공과정, 조리가정, 식사 중에 첨가되는 양에 의하여 좌우되므로, Na 섭취량을 측정하기 매우 어렵다. 가장 널리 사용되는 방법은 24시간 소변 중 배설되는 Na의 양으로부터 추정하는 방법으로 우리나라의 경우, 이러한 방법으로 섭취량을 환산할 경우 1일 200~260mEq. (NaCl 11.6~15.1g) 정도이며 이중 80% 이상이 discretionary intake인 것으로 추정된다. 따라서 앞으로 Na섭취를 줄이도록 많은 노력을 기울여야 하겠다.
