Objectives: Thirdhand smoke (THS) refers to residual tobacco smoke pollutants that remain after cigarette smoking. The purpose of this study was to determine predictors of the belief among adults in Korea that THS is harmful to children. Methods: A population-based sample of 3,000 adults (${\geq}19$ years) among a web-based panel in Korea was obtained in November 2016. The respondents filled out questionnaires, including THS beliefs, smoking status, presence of voluntary smoke-free rules at home, and support for the implementation of smoke-free regulations at home. THS beliefs were assessed with a statement that staying in a room today where people smoked yesterday can harm the health of children. Results: Overall, 92.2 % of adults believed that THS exposure could harm the health of children. Respondents who were nonsmokers, believed that SHS exposure were associated with pneumonia of children, lived in home with complete smoke-free rule at home, and supported the implementation of smoke-free regulation at home were more likely to believe that THS could harm for health of children. Conclusions: The majority of Korean adults believed that THS exposure could harm the health of children. Predictors identified in the study can be useful to address the risk of THS beliefs and promote implementation of tobacco control policies.

Levey-Jennings 정도관리는 측정치가 관리 허용치(평균 ${\pm}2SD$ 또는 ${\pm}3SD$)를 벗어나는 우연오차만 관리를 했었다면, Westgard Multi-Rules 정도관리는 우연오차와 계통오차의 분리분석을 할 수 있고 복합적용이 가능해 병원 인증 내부정도관리에서도 적극 권장하고 있다. 하지만 검체검사 정도관리에서는 kit 내 같은 기질의 정도관리 물질을 사용해 계통오차의 인지가 쉽지 않고 잦은 농도 변경으로 목표치 설정이 어려워 Westgard Multi-Rules의 적용이 힘들었다. 따라서 본 연구는 정도관리 물질을 상용화된 제 3의 물질을 사용해 신뢰성 있는 목표치를 산출하고 Westgard Multi-Rules을 적용함으로써 정도관리를 개선하고자 한다. 갑상선 검사인 Total T3를 대상으로 정도관리 물질을 B사의 Immunoassay Plus Control Level 1, 2, 3를 사용하여 ${\pm}2SD$를 벗어난 값을 제외한 1개월 동안 295회 데이터의 평균값으로 목표치를 설정하였다. 그리고 20일간 총 194회 실험의 정도관리 물질 측정치를 표준편차 지수를 이용하여 하나의 관리도상에 놓고 Westgard Multi-Rules 중 12s, 22s, 13s, 2 of 32s, R4s, 41s, $10\bar{x}$, 7T의 규칙들을 적용하여 우연오차와 계통오차를 분리하여 분석하였다. Total T3의 목표치는 정도관리 물질 1, 2, 3번이 각각 84.2 ng/dl, 156.7 ng/dl, 242.4 ng/dl로 설정되었고 표준편차는 각각 11.22 ng/dl, 14.52 ng/dl, 14.52 ng/dl로 설정되었다. 설정된 목표치를 기준으로 Westgard Multi-Rules을 적용한 뒤 유형을 분석한 결과 우연오차인 12s가 48회, 13s가 13회, R4s가 6회로 분석되었고 계통오차인 22s는 10회, 41s가 11회, 2 of 32s가 17회, $10\bar{x}$가 10회로 분석되었으며 7T는 적용되어지지 않았다. 통제 불가능한 우연오차의 유형들은 전체실험과정을 재확인하고 재검사 비중을 높이는 등의 조치를 취하였으며 통제 가능한 계통오차의 유형들은 원인을 찾아 조치사항 양식에 기록하고 필요 시 내부정도관리 위원회에 보고하였다. 상용화된 제 3의 물질을 정도관리 물질로 사용하고 목표치를 설정함에 따라 하나의 관리도 상에서 3가지 정도관리 물질에 대한 Westgard Multi-Rules의 적용이 가능하게 되었고, 그 결과 12s, 22s, 13s, 2 of 32s, R4s, 41s, $10\bar{x}$, 7T 규칙들의 분석으로 우연오차와 계통오차의 정밀분석이 가능해 졌다. 또한 ${\pm}3SD$ 내의 모든 데이터를 분석 할 수 있어 Error 검출을 최대화 할 수 있게 되었다. 이와 같이 체계적으로 Westgard Multi-Rules을 적용한 정도관리는 검체검사의 정도관리에 질적 향상을 가져다 줄 것이다.

The purpose of this is to understand the concept of Sacho on the basis of 'Sa-Sang philosophy(四象哲學)'. In oder to achieve this purpose, Sanjiao and Sacho were investigated, centering on the philophicalbasis, region. action. The conclusion would be summerized as follows. 1. Viewed in the light of a philosophical basis, Sanjiao is first recorded in Nae-Kyung(內經), a concept that Yin-Yang(陰陽), Oh-Hang(五行) in Nae-Kyung Medcine, the cosmos's order and it's moving rule could be directly applied to human body. On the contrary Sacho is a term first used by Lee Jae-Ma, a human-oriented concept that formed in Confucianism system. based on Sa-Sang type classifying in Sa-Sang Medicine. 2. Viewd in the light of a region, the upper part of Sacho is similar to the upper-jiao of Sanjiao, the mid-upper part of Sacha to the middle-jiao of Sanjiao, the mid-lower and the lower parts of Sacha to the lower-jiao of Sanjiao. But these regions are not equal to anatomical regions. Sanjiao and Sacha is similar concept from the view point of the upper and lower oder, but Sanjiao has only a concept of the upper and lower order, doesn't have a concept of the front and the rear, inside and outside. 3. Viewed in the light of a action, Sanjiao and Sacho is a similar concept from the view point of a large boundary in the life activity.Sanjiao explains the region of human body, setting imfortance on the viscera physiology, on the contrary Sacho explains the whole function of human body including one's heart's desire, physical constitution and the visceral physiolosy. 4. Viewed in the light of produsing-wasting activity. sanjiao and Sacho have both produsing action and wasting action. but Sacho has a more concrete concept of produsing action by using a term-Sa Hae(四海) 5. Viewed in the light of vital energy(氣)'s action, Sajiao give the first consideration to the rising and falling action of vital energy, on the contrary Sacho give the first consideration to the transversal circulation of vital energy and the deviation of it in each part. According to the above results, Sacho must be discussed separately from Sanjiao, it is recommended that further study is necessary to understand the concept of Sacho on the basis of Sa-Sang philosophy.

Among a number of factors related to the effect of acupuncture and moxibustion treatment, prescriptions do important work. Traditional eastern doctors also placed emphasis on prescriptions of acupuncture and moxibustion, and a lot of experiences have been accumulated. The method forms prescriptions of Sa-am acupuncture therapy pivots on five transport points. Studies show prescriptions are made on the basis of the theory of 'Wang Xiang Xiu Qiu Si'(旺相休囚死) used engendering and restraining of five phases, and it is considered the principle of transformed prescriptions through this theory. Because there is still no study analyzing prescriptions of Sa-am acupuncture by existing principles, we report opinion about Combination principle of points in them. 1. We studied history of acupuncture and moxibustion, development and kinds of points' Combination principle. 2. Around Combination principles of points in Classic of Difficult Issues and Internal Classic, we analyzed and compared between Combination principles of points in Sa-am acupuncture therapy and them in Korea and overall acupuncture methods. 1. There were many Combination principles of acupunture point combination in Classic of Difficult Issues, Internal Classic and Korea acupuncture methods. For example, Point combination of the same meridian, Point combination of the different meridian, Exterior-Interior point combination, Point combination of the same name meridian, Point combination of the multiple meridian, Point combination of Adjacent and Distant points, Left-Right point combination, Anterior-Posterior point combination, Superior-Inferior point combination, Brook point and Stream point combination, Triple energizer point combination, Eight meeting point combination, Five transport point combination, Source-Connecting point combination, Alram point and Transport point combination, Mother-Sun meridian combination, Empirical point combination, Important point combination, Point combination according to syndrome. 2. Existing Combination principles of points in prescriptions of Sa-am acupuncture therapy included every rule. 3. They could be evidences that prescriptions of Sa-am acupuncture therapy are forms inheriting and developing acupuncture and moxibustion treatments.
