In the second quarter of 2017, the size of the household debts has been reaching 1,388 trillion won. And, because the size of the housing mortgage loans has been closing in upon 560 trillion won, around 40.3% has been crowded in the housing demand funds. Regarding this, there is no choice but for the influence on the entire economy to be high according to the increase of the delinquency rate in case the economy worsens or the recession continues. This study intends to suggest the implications regarding the housing mortgage loans in the long-term viewpoint through the influence evaluations of the macroeconomic variables related to such housing mortgage loan delinquencies. The macroeconomic variables that were used were the housing mortgage loan delinquency rate (TOD), the price index of the average buying and selling of the real apartment transactions (APT_PRICE), the new housing mortgage loan interest rate (HINTEREST), the index of the industrial products (IIP), the amount of money in circulation (M2), the monetary amount of the housing mortgage loans (HML), the amount of the apartment transactions (TRADE), and these were unfolded in the viewpoint of the relationship with the real estate market and the currency policy. As a result of the unit root test, it appeared that, regarding the amount of the apartment transactions, the time series raw data had been maintaining the stability. And it was able to find out that the data of the remaining variables, including the housing mortgage loan delinquency rate (TOD), had been getting stabilized through the primary difference. Because, as a result of a co-integration test, at least 6 variables possess the linear, the selection of the model used the VEC model, and, regarding the optimal differential, the 1st model was selected based on the SC (Schwarz Criterion) value. As a result of taking a look at the granger causality relationship, it appeared that the variables that had the influences on the housing mortgage loan delinquency rate were the price index of the average buying and selling of the real apartment transactions (APT_PRICE), the new housing mortgage loan interest rate (HINTEREST), the index of the industrial products (IIP), the amount of money in circulation (M2), and the amount of the apartment transactions (TRADE). As a result of analyzing the VECM (Vector error correction Model) short-run equilibrium relationship, it appeared that the housing mortgage loan delinquency rate were influenced by the index of the average price of the buying and selling of the real transactions of the apartments and by the index of industrial products. As a result of a reaction to a shock, the positive (+) correlation appeared between the housing mortgage loan delinquency rate and the amount of the transactions of the apartments (TRADE) and, also, the interest rate of the new housing mortgage loan (HINTEREST). Eventually, regarding the housing mortgage loan delinquency rate, if the interest rate goes up, right away, an increase of the delinquency rate takes place. And, it appeared that, if the monetary amount of the housing mortgage loan becomes big, the delinquency rate decreases. This is because the delinquency rate has the influences on the incomes and others of the like, it can be under the control of the interest rate policies. The meaning of this research is that it investigated about the relationship with the housing mortgage loan delinquency rates by considering the indices in the real estate market and the currency policies at the same time. And, it is that, in the condition in which the scale of the housing mortgage loan having become big at present, raising the interest rate can aggravate the confusion more in the market. As a result, with regard to the proceeding with the real estate policies, the prudent and macroscopic approach is needed. And the researches on the relationships of the indices will be needed more in the macroscopic viewpoint.

본 연구는 측모두부방사선사진 촬영시 발생될 수 있는 두부회전이 측정된 선, 각계측치들에 어느 정도의 투사오차를 야기시키는지 알아보기 위해 조선대학교 의과대학 해부학교실에 소장중인 건조두개골 중 비교적 상태가 양호하고 특별한 비대칭이 없는 영구치열기의 건조두개골 17개를 표본으로 선택하여 시행하였다. 각각의 건조두개골을 수직축(Z축)을 중심으로 기준위치(0˚)에 대해 1˚ 간격으로 ±15˚ 까지 실험적으로 회전시켜 총 527장의 측모두부방사선사진을 촬영하였다. 이를 근거로 기준위치(0˚)에서의 계측치와 각 회전각에서의 계측치들 사이에 paired t-test를 시행하여 측모두부방사선사진 계측치 간의 차이를 규명하였으며, 이를 통해 투사오차의 관점에서 교정학적으로 유용한 측모두부방사선 계측항목을 구한 결과 다음과 같은 결론을 얻었다. 1.각계측항목이 선계측항목에 비해 투사오차가 작았다. 2.각계측항목은 정중시상면에 위치한 기준점들을 많이 포함할수록 투사오차가 작았다. 3.수평선계측항목의 길이는 필름방향으로 회전됨에 따라 점진적으로 감소되었으나, 초점 방향으로 회전됨에 따라서는 증가되다가 감소되었으며 상대적으로 그 변화양이 작았다. 4.두부회전에 따른 투사오차는 수직선계측항목에 비해 수평선계측항목에서 컸다. 5.수직선계측항목은 회전축으로부터 거리가 증가함에 따라 투사오차가 증가하였다. 이상을 종합해 볼 때 두부회전에 따른 측모두부방사선사진 계측치의 투사오차를 최소로 하기 위해서는 선계측항목보다는 각계측항목을 사용하는 것이 유용할 것으로 사료된다. This study was performed to find out the effect of projection errors on cephalometric linear and angular measurements according to head rotation during taking lateral cephalometric radiographs. Seventeen skulls with permanent dentition and no gross asymmetry were obtained from the Department of Anatomy, Medical School, Chosun University. Total 527 x-ray films were taken with 1˚ interval from the reference position(0˚) to ±15˚ around the vertical axis (Z axis) which is perpendicular to the midpoint of the line connecting the center of two ear rods in submento-vertex direction. Statistical analysis was performed by faired t-test if there were statistically significant differences between the mean of the reference position(0") and that of each rotation angle. The following results were obtained. 1.The projection errors of angular measurements were smaller than those of linear measurements. 2.The projection errors of angular measurements including midline landmarks were smaller than those including bilateral landmarks. 3.The horizontal linear measurements were gradually decreased when the skull was rotated toward the film, but slightly increased and then decreased when the skull was rotated toward the focal spot. However, the changes were smaller in focal direction. 4.The projection errors of horizontal linear measurements were larger than those of vertical linear measurements. 5.The projection errors of vertical linear measurements were increased with increased distance from the rotation axis to vertical measurements. It is concluded that the use of angular measeurements rather than linear measurements is recommended to minimize the projection errors.

Objectives : Since mid-90s there have been numerous studies to understand and establish the concept of internet addiction as one of diagnostic classifications in psychiatry. Among them, many studies on the personality characteristics of internet addiction have been conducted. Recently, interests are expanding to temperament characteristics of internet addictors but the subjects have been limited to adolescents, In this study, the temperament characteristics of internet addiction in adults were investigated using Tridimensional Personality Questionnaire (TPQ). Methods : 430 participants (189 males, 241 females) answered the on-line and off-line questionnaires from January to December in 2005. Participants completed questionnaires on demography and the onset of internet use, Young's Internet Addiction Scale and Korean Contracted Version of Cloninger's Tridimensional Personality Questionnaire (TPQ). Rcsults : There were statistically significant differences in age, marital status, occupation, psychiatric history, smoking history, alcohol history and onset age of internet use among non-addiction, overuse and addiction groups by Young's scale. Of the TPQ items harm avoidance (HA) scores were significantly higher in addiction and overuse groups than non-addiction group. Reward dependence (RD) scores were significantly lower in addiction group than non-addiction group. Novelty seeking (NS) scores were significantly higher in addiction group than non-addiction group. Conclusion : This study suggests a significant difference of novelty seeking in temperament characteristics between adults and adolescents with internet addiction. Further studies are expected for profound understanding of internet addiction.

목적 : 최근 저출산, 국민 소득 수준 향상 등에 따라 산모들이 분만 후 처치와 모유 수유 등을 위해 전용 공간인 상급 병실을 선호하는 경향이 있다. 한편, 국민건강보험에서는 의료기관이 상급병실을 전체 병상의 50% 미만으로 유지하도록 규정하고 있다. 본 연구는 분만 환자의 일반 병실 또는 상급 병실 선택 이유를 파악하고 실제 병상 사용 현황을 검토하여, 병상 이용의 효율성과 형평성을 높이는 정책적 방안을 모색한다. 방법 : 2011년도 기준으로 분만 건수가 10건 이상인 요양 기관 대상으로 요양 기관 종별, 병상 수, 지역을 고려, 166개 의료기관을 표본 추출한 뒤, 2012년 11월 1일부터 11월 30일 까지 설문 조사 전문 업체에 의뢰하여 802명의 산모를 대상으로 1:1 설문조사를 실시 하였다. 대상자들의 병실이용 현황과 병실 선택과 관련된 상황과 인식, 만족도를 조사하였다. 결과 : 총 802명의 산모 중 상급 병실 이용자/선호자는 각각 690명(86%)/684명(85.2%), 일반 병실은 112명(14%)/118명(14.8%) 이었다. 35세 미만의 산모에서 상급 병실을 더 많이 이용하였다(87.3% vs. 80.3%, P=0.026). 의료기관 종별 유형은 의원, 병원, 종합병원, 상급종합병원 순서로 산모들의 상급병실 이용이 많았다. 제왕절개 여부, 다태아 여부, 경산 여부는 상급 병실의 이용에 유의한 차이가 없었다. 병실의 만족도는 상급병실이 일반병실 보다 유의하게 높았고[5.9±1.0 vs. 5.4±1.2 (0-7 scale), P<0.01], 가구 총 소득 역시 상급병실 이용자에서 높았다. 상급병실 이용 이유는 분만 후 충분한 요양 (78%), 모유 수유(6.1%), 방문 가족 접객(5.4%) 등이었다. 추후 병원 이용 시 상급 병실 선호도는, 분만의 경우가 분만 외 질환 시 보다 높았다(81.8% vs. 44.9%, P<0.001). 결론 : 분만 입원의 특성상 사생활 보호, 충분한 요양의 필요, 모유 수유, 가족공간의 필요성 때문에 상급병실에 대한 선호 및 실제 이용이 높다. 반면 소득수준, 보험가입여부, 연령에 따라 상급병실 이용에 격차가 생기고 있으므로, 분만에 한해 상급병실료의 국가 지원이 필요하며 아울러서 상급병실 비율 완화와 병실료 적정화와 같은 정책적 제언이 필요할 것이다. Purpose : Demand of specialized maternity ward is increasing as national income level rises. However, the National Health Insurance limits the number of hospital’s non-standard room to less than 50% of total hospital beds. Therefore, this research was performed to investigate the utilization of non-standard room among the Korean women who recently delivered baby in medical facilities in order to examine the factors affecting their selection. Methods : One hundred sixty six medical facilities which deliver a minimum of ten cases in the year 2011 were selected and categorized by type, region, and size. A cross-sectional survey was done in November 2012 by a professional research survey company. Eight hundred and two pregnant women answered the questionnaire through a face-to-face interview. Results : Of the 802 expecting mothers, 690 (86%) occupied non-standard room and 684 (85.2%) preferred non-standard room to the standard room. Satisfaction levels were significantly higher in mothers occupying non-standard room [5.9±1.0 vs. 5.4±1.2 (0-7 scale), P<0.01] and high-income families used non-standard room more often. Reasons for using non-standard room included adequate convalescence (78%), separate place for breastfeeding (6.1%), and convenience on receiving visitors (5.4%). Preference for non-standard room on next visit was higher in case of delivery compared to other cause of hospitalization (81.8% vs. 44.9%, P<0.001). Conclusions : Preference and actual use of non-standard room after delivery was significant. In spite of concrete preference, there was certain barrier in use of non-standard room according to income and types of hospitals. Therefore, changes of policy are needed such as insurance support for room charge in case of delivery.
