Objectives: This study was designed to introduce distinctive Do-In techniques among the many found in the book 'Euibangyoochi'. Methods: 'Do-In section' of Euibangyoochi was translated, and distinctive Do-In techniques were extracted from it. These techniques were categorized as 'using specific actions', 'using vocal sounds'. Results: The Do-In methods in the 'Do-In section' of Euibangyoochi were categorized. The first category includes Do-In methods that involve specific actions, such as 'Myung Chun Go', 'Go-chi Beob', 'Ak-go Beob', 'Gun-yok Beob', and 'An-ma Beob'. The second category is the Do-In technique using vocal sounds, known as 'Yuk Ja Gyeol'. Conclusion: The 'Do-In section' of Euibangyoochi contains numerous Do-In techniques recorded in various texts. Among them, techniques with specified names were extracted and categorized. While there are currently no studies on the actual effects of these techniques, it is hoped that future research can validate their efficacy.

진해ㆍ마산만에서 수온, 염도 및 DO농도를 연직방향으로 1년동안 측정하였다. 관측된 수온 및 염도 자료를 이용하여 성층화 특성을 분석하고, DO농도의 연직변화를 성층화 특성 및 저질오염도와 관련하여 분석하였다. 분석결과, 진해ㆍ마산만의 수온 성층화는 4월 이전에 시작되어 10월경에 종료되는 양상을 보이고 있는 것으로 판단되었다. 또한, 1998년 4월 연직방향의 평균 염도변화는 3.9(equation omitted) 정도로 증가되고, 1998년 8월 9.3(equation omited), 10월 4.3(equation omitted) 정도가 유지되어 가을철에도 염도 성층이지속되고 있는 것으로 파악되었다. 한편, DO 농도는 성층화가 시작되는 4월을 기점으로 연직방향 평균 DO농도변화도 2.6(mg/L)에서 6월 8.3(mg/L), 8월 5.9(mg/L), 9월 7.24(mg/L), 10월4.4(mg/L)으로 명확한 성층화 양상을 보이고 있다. DO 농도변화는 전체적으로 해역의 오염도와 밀접한 관련이 있으나. 성층화 기간동안 연직방향 DO 농도편차가 크게 나타나고 있는것은 수온 및 염도성층에 의한 표 저층간의 물질교환 저해에 의한 영향도 직접적인 요인으로 작용하고 있은 것으로 파악되었다.

가상 현실 공간에서 실사 영상 및 그래픽 환경에 대해 사용자 움직임에 대응하는 영상을 제공하는 three degrees of freedom plus(3DoF+) 및 six degrees of freedom(6DoF) 시스템은 실감형 미디어를 제공하기 위해 서로 다른 위치에서 동시에 취득된 다수의 초고화질 및 고해상도의 영상 집합 전송을 요구한다. 다수의 영상들을 사용해 사용자 시점 영상을 생성할 때, 기존의 영상 압축 코덱에서 발생했던 것과는 다른 형태의 품질 저하가 발생하여 기존의 영상 품질 평가 기법들은 3DoF+ 및 6DoF 시스템 평가에 적합하지 않다. 본 논문은 3DoF+ 환경에서 합성된 사용자 시점 영상에 대한 다양한 객관적 영상 품질 평가 기법에 대한 성능 평가를 소개한다. 또한, 기존의 객관적 영상 품질 평가 기법을 조합하여 주관적인 평가와 상관관계를 더욱 높인 평가 기법인 슈퍼 메트릭(super metric)을 제시한다. 3DoF+ 몰입형 비디오 평가 시 제안한 기법을 사용하였을 때, 주관적 평가 점수와의 상관관계에서 peak signal-to-noise ratio(PSNR) 대비 0.4513의 상승이 있었음을 확인하였다.

The aim of this study was to identify community-level childcare infrastructure for infants and toddlers and to use the data to categorize community types using K-Means cluster analysis with spatial constraints. Seven indicators of childcare resource supply were used for the purpose of categorization and the results revealed six types of community cluster. Communities in the Type 1 cluster provided sufficient parks, libraries, and kindergartens, but lacked pediatric facilities and private education institutions. This cluster comprised small cities and rural areas in Gangwon-do, Gyeongsangbuk-do, Chungcheongbuk-do, and Jeollabuk-do. The Type 2 cluster had numerous pediatric facilities and childcare centers, but lacked other childcare infrastructure. This comprised small and medium-sized cities in Gyeonggi-do, some areas in Chungcheongnam-do, Chungcheongbuk-do, and Gangwon-do bordering Gyeonggi-do. The Type 3 cluster comprised Busan, Daegu, and Gyeongsangnam-do, but had insufficient childcare infrastructure as a whole. Type 4 had the largest number of childcare centers, libraries, and private education institutions and comprised Jeollabuk-do, areas near Gwangju, and Jeju-do. Type 5, consisting of Seoul, Incheon and the southern part of Gyeonggi-do had many pediatric facilities and certified childcare centers, but lacked other childcare infrastructure. Type 6, being the rural areas and islands in Jeollanam-do, had sufficient kindergartens, but other infrastructure was insufficient. These results are expected to provide local government with policy implications in terms of relieving the childcare burden on residents with infants and toddlers.

The shore platforms at Dok-do could be an important and clear indicator showing dimensional reduction of Dok-do. Especially flat type shore platforms are distributed in the southern coast of Dok-do island, composed of weak rocks against erosional resistance like interbedded lapilli tuff and massive tuff breccia. The distribution of shore platform is partially related to the wind direction at Dok-do island. The primary SW- and secondary SE winds are representative among wind directions at Dok-do, maintaining from spring to the autumn. Therefore, wide shore platforms could be developed by waves approaching from SW and SE directions in the southern coast of Dok-do. The sea stacks like Gunham-rock, Neopdeok-rock, Keungaje-rock and Jakeungaje-rock on the western coast are also considered to be formed by wave erosion from the SE direction. The shore platforms in the southern coast of Dok-do island were developed since ca. 7,000 yr. BP, when sea level raised almost to the present level. The average extension speed of shore platform was calculated to 4.0mm/y, because the broadest shore platform with the width ca. 28m was extended for ca. 7,000 years. The width's dimension of shore platform at Dok-do reflects a slow extension rate in the present, although erosional process will be faster with the sea level rise in the future.

동해 한복판에 위치한 울릉도와 독도의 화산암들에 대한 새로운 K-Ar 연대측정으로 독도로부터는 $3.67{\pm}0.40\sim1.89{\pm}0.29Ma$, 그리고 울릉도로부터는 $8.07{\pm}0.39\sim0.51{\pm}0.07Ma$의 결과를 얻었다. 이는 독도와 울릉도 모두 화성활동의 기간이 기존 연구에서 밝혀진 것보다 연장됨을 나타낸다 울릉도의 화산활동 시작은 지금까지 알려졌던 것보다 훨씬 오래전인 $8.07{\pm}0.39Ma$전까지로 확장될 가능성이 있으며, 독도의 최후기 조면암 분출 및 관입은 울릉도의 화성활동 시기로 보고되었던 시기와 중첩되는 $1.89{\pm}0.29Ma$까지 지속되었다. 그러나 울릉도 화산체의 형성은 주로 2.7Ma 이후에 일어났으며, 독도의 화성활동은 이 시기 이전에 대부분 종료된 것으로 보인다. 이는 화산체의 주형성기로 볼 때 독도가 울릉도 이전에 형성되었음을 시사하며, 열점화산활동에 의해 독도 동남부의 해산들로부터 시작하여 독도, 그리고 울릉도로 화산활동이 이어졌다는 해석과 합치한다.

Background: Humidifier disinfectant is a biocidal product used in the water tanks of humidifiers to prevent the growth of microorganisms. Although there are a huge number of cases of reported humidifier disinfectant-related health effects across the entire Korean population, their numbers are distributed differently depending on the region. Objectives: This study aimed to investigate the regional distribution of enrollment cases who reported humidifier disinfectant-related health effects. Methods: This study used data on 6,240 subjects who experienced humidifier disinfectant-related health effects and who enrolled their cases which is conducted by the Korea Ministry of Environment. We examined the regional distribution of the enrolled cases based on sixteen administrative divisions and assessed the: 1) crude number; 2) proportional rate; and 3) age-standardized proportional rate of enrollment by region. Results: When we examined the crude number of enrollments by region, the highest number were in Gyeonggi-do Province (n=1,896), followed in order by Seoul (n=1,405), Incheon (n=436) Busan, Daegu, Gyeongsangnam-do Province, Daejeon, Chungcheongnam-do Province, Gyeongsangbuk-do Province, Jeollabuk-do Province, Gwangju, Chungcheongbuk-do Province, Gangwon-do Province, Jeollanam-do Province, Ulsan, and Jeju-do. When we examined proportional rate of the regional enrollment (cases per 100,000 population), Daejeon (n=16.2) was the region with the highest rate, followed in order by Gyeonggi-do Province (n=16.1), Incheon-do Province (n=15.9), Seoul, Daegu, Gwangju, Jeollabuk-do Province, Chungcheongnam-do Province, Busan, Chungcheongbuk-do Province, Gangwon-do Province, Gyeongsanbuk-do Province, Gyeongsangnam-do Province, Ulsan, Jeju-do, and Jeollanam-do Province, which is inconsistent with the order in terms of crude numbers. However, when we examined the age-standardized proportional rate of regional enrollment (cases per 100,000 population), their ranked distribution is consistent with the crude rate. Conclusions: This study observed that the regional distribution of the enrolled cases who reported humidifier disinfectant-related health effects is inconsistent with the regional distribution of the proportional rate of enrollment cases, which may be caused in part by the volume of the inherent population of each region.
