지역별 적정 주택량을 공급하기 위해 수요예측 모형을 구축한다 예측모형은 자료유형에 따라 다소 차이가 있으나 시계열자료(Time Series Data) 분석기법에 의한 모형 구축 시 추정대상 지역특성을 민감히 반영할 수 있는 영향인자가 필요하다. 도시지역을 인구규모로 분류하여 영향인자를 분석할 경우, 대도시와는 달리 중 $\cdot$ 소도시는 주택량과 상수도보급률의 변화가 일정기간 민감한 상관관계가 존재하는 것으로 조사되고 있다. 이에 따라 중 $\cdot$ 소도시 주택수요 예측을 위해 상수도보급률을 유용하게 적용할 수 있는 구간, 즉 예측모형 구축이 가능한 시점까지의 도시 주택량과 인구수 규모를 찾아낼 필요가 있다. 따라서, 전국 중 $\cdot$ 소도시를 대상으로 주택량과 상수도 보급률의 상관관계가 중 소도시 지역에서만 있는 것으로 조사된 기존 연구 결과를 재 입증하고, 지역별 상관관계가 완화되는 시점의 시기, 상수도보급률, 주택량, 인구수 규모를 발견하는 것을 본 연구의 목적으로 한다. The analysis described in this paper indicate the existence of a correlationship for housing demand and water supply ratio. Using subjective statistical data for the trend of population on regional area, water supply ratio and the number of households, the paper examines the correlationship of forecasting factors for apartments in the ways in which the tendency of demands for apartments and water supply ratio have been analyzed within small and mediumsized city. Differences in the correlationship on the several scale of a city are also taken into account in the analysis. The summary table of the tendency for housing supplies, population and water supply ratio on each scale of a city was generated using data from LAIB. This study attempted to address certain factors that are measurable within a specified paradigm, in order to investigate the extent to which the expectation of apartment supplies can be estimated from the correlationship of water supply ratio. Therefore, it can be suggested that the limited scale of a city are set to maintain the correlationship for housing demands and water supply ratio.

자연치열에 대합하는 완전 무치악 환자의 수복에서 임플란트를 이용한 고정성 보철물 또는 임플란트 피개의치는 좋은 치료법이다. 그러나, 완전 고정성 보철을 통한 치료는 충분한 골질, 골량이 뒷받침되어야 하기에 그 한계가 있다. 한편, 최근에는 임플란트 고정성 보철물과 함께 그것을 가철성 국소의치의 지대치로 사용하는 치료가 행해지고 있다. 본 증례보고는 자연치열에 대합되는 두 상악 완전 무치악 환자에 있어 임플란트 피개의치와 임플란트 고정성 보철물 및 가철성 국소의치를 이용한 치료 및 8년 경과관찰, 유지보수를 비교 고찰해 보고자 한다. An implant-supported fixed dental prosthesis (ISFDP) or an implant-supported overdenture (IOD) are good options when treating a completely edentulous jaw opposing natural teeth. However, an ISFDP for a full arch requires sufficient bone quality and quantity, which limits its application. Meanwhile, using an ISFDP as an abutment of a removable partial denture has been considered recently. This clinical report discusses the treatments applied to two patients with edentulous maxillas and opposing natural teeth: one was treated with an IOD and the other was treated with an ISFDP and removable partial denture. Follow-up and management were performed for 8 years.

With increasing interest and research on smart cities, there is also an increasing number of studies on urban facilities that can be built within smart cities. According to these studies, smart cities' urban facilities are likely to become high value-added industries. However, the concept of smart city is not clear because it involves various fields. Therefore, in this study, the definition of Next-Generation(N.G) Smart City Facilities with Digital Twin and Digital Chain is carried out through a multidisciplinary approach. Based on this, Next-Generation Smart City Facilities will be divided into High Value-Added Products and Big Data Platforms. Subsequently, the definition of the Digital Chain containing the data flow of the entire process built through the construction of the Digital Twin proceeds. The definitions derived are applied to the Next-Generation Noise Barrier Tunnel to ensure that data is exchanged at the Digital Twin stage, and to review the proposed configuration of the Digital Chain and Data Flow in this study. The platform definition and Digital Chain of Next-Generation Smart City Facilities proposed in this study suggest that it can affect not only the aspects of data management that are currently in the spotlight, but also the manufacturing industry as a whole.

본 연구는 12주간 댄스스포츠와 저항운동이 폐경 후 중년 비만여성을 대상으로 실험군(n=14)과 대조군(n=15명)으로 구성하여 신체조성, 근육감소증, 염증지표, 인슐린 저항성, 렙틴을 비교 분석하고 동시에 성인병의 예방 차원과 과학적인 자료를 제공하는데 연구 목적이 있다. 신체조성의 변화는 체중(p<.05), 체지방률(p<.05), 허리둘레(p<.05), 근육지수(p<.05)는 실험군과 대조군에서 유의한 차이가 나타났다. 인슐린 저항성과 렙틴의 변화는 공복 혈당(p<.05), 인슐린(p<.05), leptin(p<.05)은 실험군의 감소로 유의한 차이가 나타났다. 이러한 결과는 첫째, 중년 비만여성은 각종 성인병을 예방하기 위해서는 댄스스포츠와 저항운동프로그램을 실시하는 것이 체중, 체지방률, 허리둘레, 근육지수 실험군에서 효과적으로 나타났다. 둘째, 댄스스포츠와 저항운동프로그램을 실시하여 폐경 후, 중년 비만여성의 공복 혈당, 인슐린과 Leptin, 호르몬에서 효과적으로 나타났으며, 따라서 염증지표와 HOMA-IR은 운동 기간이 더욱 필요할 것으로 생각된다. 이상과 같은 결과를 종합하면 중년 비만여성 염증지표는 유의한 차이가 나타나지 않았다. 따라서 댄스스포츠와 저항운동은 중년 비만여성 신체조성, 근육지수와 공복 혈당, 인슐린, Leptin, 호르몬 개선에 효과적인 방법으로 생각된다. 추후 장기적인 댄스스포츠와 다양한 저항운동프로그램 연구 및 분석이 요구되는 바이다. The purpose of this study was to compare and examine the effect of combined exercise on body composition, sarcopenia, inflammatory makers, insulin resistance, and leptin in postmenopausal obese middle-aged women who were divided into the experimental group (n=14) and the control group (n=15) through 12-week program of dance spores and to provide scientific data for prevention of adult diseases. Regarding change of body composition, there were significant differences in weight (p<.05), body fat percentage (p<.05), belly (p<.05), and muscle condition score (p<.05). Regarding changes of insulin resistance and leptin, there were significant differences in reduction of fasting blood sugar (p<.05), insulin (p<.05), and leptin (p<.05). First, to prevent adult diseases, executing combined exercise program was effective for weight, body fat percentage, belly, and muscle condition score in obese middle-aged women. Second, fasting blood sugar, insulin, leptin, and hormones were effectively reduced in obese middle-aged women after dance spores program, and it is considered that there should be more exercise period for inflammatory makers and HOMA-IR. From the above results, there was not a significant difference in inflammatory makers of postmenopausal obese middle-aged women. Thus combined exercise program is considered to be an effective method for improvements of body composition, muscle condition score, fasting blood sugar, insulin, leptin, and hormones.

The purpose of this study is to examine how elementary school science textbooks are designed to facilitate students’ inquiry abilities in South and North Korea. For this, we investigated the weight of sub-area science in the entire units, the tendency of inquiry using Romey’s analysis method, differences in the composition of units to improve inquiry capabilities, and differences in how concepts and inquiry are applied to solve real-life problems. As a result of the analysis, North Korean science textbooks showed different weights in each area of physics, chemistry, biology, and earth science. The inquiry tendency of South Korean and North Korean textbooks was similar, but North Korean textbooks were described more exploratively in visual materials than South Korea. South Korean textbooks suggested more diverse inquiry activities than North Korean textbooks. North Korean textbooks are more exploratory in the title of the unit, while South Korean textbooks are concept-oriented and abstract. North Korean science textbooks provided opportunities to use concepts and inquiry skills learned to solve real-life problems. As a result of this study, it can be seen that elementary school science textbooks in South Korea and North Korea show differences in their tendency of inquiry. The findings are expected to contribute to the development and improvement of the next curriculum and textbooks.
