This study analyzed official duties and personnel practices of Hyangcheong(鄕廳), administrative organization in which sajok(士族) participate this office, and Jakcheong(作廳), hyangree(鄕吏)'s office, of Anbyeon of Hamgyeong Province in the 19th century. Although there have beeen somewhat of case study of Gyeongsang, Honam, etc., study on Hamgyeong Province has been almost nonexistent because of the limitation of materials. Hence, this paper specifically examined Hyangcheong and Jakcheong's official duties and personnel practices through an article of 'a list of Hyangcheong and Jakcheong's officials' of Anbyeon, newly found, which is in the possession of this writer. Especially, this study virtually traced individual ststus and family by analyzing Hyangcheong and Jakcheong's 40-official duties and a list of 330-ofiicial duties for sixs years. And then by comparing it against Jokbo(族譜), I have grasped 19-Famlily of them. Executives of Hyangcheong could be grasped as they were status of Yangban(兩班), but members of Jakcheong were hardly identified because they were status of hyangree, thus most of them were not enscrolled in Jokbo. Hyangcheong and Jakcheong's official duties could be found by compare it with other area in Ehubgi(邑誌) Hamgyeong Province. the features of officiak duties are as in the following. On general administrative organization, Sajok's Hayngcheong, Jakcheong as general administrative organization and Jangcheong(將廳) as police work existed. As Pyeongando and Hamgyeongdo were border areas, Jangcheong was independent and led other institutions. However, in Anbyeon, Hojang(戶長) of Hayngcheong and Jakcheong divided dudies and commanded. Hojang'role was higher than any other areas, Because Hojang is in charge of Jangcheong's functions. Jakcheong was centrally operated by Hojang, Eebang(吏房), and Hyeongbang(刑房), so-called 'Samgonghyeong(三公兄)', Whereas Anbyeon was operated by Hojang, Eebang, Chunchong(千摠). In the general areas, While Juasu(座首) Byeolgam(別監), Executive of Hyangcheong, manages each warehouse(倉) where the nation's tax revenues are kept, In Anbyeon besides Joasu, Hyangso(鄕所). The principle of Hyangcheong and Jakcheong's personnel practices was one-period, but there were many consecutive terms, every other year terms, or tranference into other area. Police work was assumed by specific persons because it was relatively specialized job, However in case of Ghamsaek(監色) of each warehouse(倉), Hyangso(鄕所) of Hyangcheong or Hojang of Jakcheong had held plural offices, and was solely responsible it. On the overall features of its operation, Hyangcheong held plural offices, but rotation was made only within Hyangcheong. On the other hand, in the case of Jakcheong, Hojang, Eebang, and even Buriebang circulated their positions, but the other Hyangree rotated each Saek(色) and Guamguan of each warehouse(倉). This writer confirmed that unlike Gyeongsang and Hamgyeong, Hyangcheoung or duties of Hyangree were not handed from generation to generation by several families and, many families shared their work by circulating positions.

This study aims to explore scientific reasoning that students and their teachers constructed in elementary science classroom discourses in terms of basic reasoning types; deduction, induction, and abduction. For this research, data were collected from 13 classes of 4th grade science activities during a period of three months and analyzed three types of scientific reasoning in elementary school science discourses. We found that deduction (one discourse segment), induction (one discourse segment), and deduction-abduction (two discourse segments) were presented in the discourses. They showed that: first, scientific reasoning proceeded explicitly or implicitly in elementary science discourses; second, the students and their teachers have potentials to increase the quality of reasoning depending on their inter-subjectivity; and last, the students' background knowledge were very important in the development of their reasoning. Implication and remarks on science education and research were presented based on this results as well.

Objectives Children are one of the most vulnerable populations to the impact of disasters. We aimed to examine children's mental health in the area affected by the Hebei Spirit oil spill accident on December 7, 2007. Methods A cross-sectional questionnaire survey was conducted using the Korean versions of the Children's Depression Inventory and State Anxiety Inventory for Children on 1,362 children attending elementary schools in the affected area. The information on distances between the nearest contaminated coastline to the child's residential house or attending school were obtained using a web-based map by inputting two address points. The symptom risks of depression and state anxiety were estimated by multiple logistic regression analyses adjusted for age, gender, and other covariates. Results Children with the closest distance (in the fourth quartile) to the school from the contaminated coastline showed a significantly higher symptom risk of depression compared to those with the farthest distance (first quartile)(odds ratio, 2.73; 95% confidence interval, 1.40-5.33), while there was no significant association between anxiety symptoms and distance. Conclusions Children, a vulnerable population for mental health impact by the oil spill accident, should be included in mental health programs in the community along with their family as victims of the disaster.

The purpose of this study was to investigate the existence aspects of the Hyangri class in Imsilhyeon, Jeolla Province in the latter half of Joseon based on Woonsuyeonbangseonsaengan, which provides lists of Hyangris in Imsilhyeon from the fourth year(1724) of King Gyeongjong's reign to the early 20th century. It contained the names of total 704 Hyangris, who included 119 Kims, 103 Eoms, 103 Jins, 87 Parks, 86 Muns, 66 Lees, 31 Baeks, 27 Hwangs, and 17 Taes. In addition, there were 12 more family names that produced fewer than ten Hyangris. Based on the share of representative family names among the Hyangris of the area, it is estimated that the dominant family names were Kim, Eom, Jin, Park, Mun, and Lee. Another interesting aspect is that the Jeon and Yang families produced no Hyangris in the 19th century, whereas the Hwang family produced 5% of Hyangris in the century with the Jin family accounting for 10% or more. These findings show that little changes were consistent within the community of Hyangris despite the fact that a couple of families were dominant. The family clans of the family names were checked in Nosogyean, which records that they were the Kim family of Gyeongju, Eom family of Yeongwol, Jin family of Namwon, Park family of Hamyang, Mun family of Nampyeong, and Lee family of Gyeongju. The study then examined the family names of 76 Hojangs that were recorded to hold the Hojang title in Woonsuyeonbangseonsaengan to see whether the family names that produced higher-level Hyangris were the same as the ones above. There was an overall agreement between the family names that produced a lot of Hojangs and those that produced the most Hyangris, but there were differences according to the periods. Six family names produced Hojangs in similar percentage in the 18th century, and only three family names, which were the Jin family of Namwon(13), Mun family of Nampyeong(9), and Eom family of Yeongwol(6), produced more than ten Hojangs in the 19th century. Other noteworthy changes in the 19th century include the rapidly rising frequency of Hojangs serving the term twice or more compared with the 18th century and the concentration of Hojangs on certain family names. These findings indicate that six family names coexisted in the active production of Hyangris in the community of Hyangris in Imsilhyeon in the latter half of Joseon, that there were changes to the family names of higher-level Hyangris internally according to the periods, and that a shift happened toward the leadership of certain family names in the society of Hyangris.

This paper is to reproduce the result of Kim et al. (2014) by deriving a benchmark dose lower bound (BMDL) of lead based on the 2005 cohort data set of Children's Health and Environmental Research (CHEER) data set. The ADHD rating scales in the 2005 cohort were not consistent along the three follow-ups since two different ADHD rating scales were used in the cohort. We first unified the ADHD rating scales in the 2005 cohort by deriving a conversion formula using a penalized linear spline. We then constructed two linear mixed models for the 2005 cohort which reflected the longitudinal characteristics of the data set. The first model introduced the random intercept and the random slope terms and the second model assumed the first order autoregressive structure of the error term. Using these two models, we derived the BMDLs of lead and reconfirmed the "regression to the mean" nature of the ADHD score discovered by Kim et al. (2014). We also noticed that there was a definite difference between the sampling distributions of the two cohorts. As a result, taking this difference into account, we were able to obtain the consistent result with Kim et al. (2014).

The ministry of Environment of Korea initiated two follow-up surveys in 2005 and 2006 to investigate environmental effect on children's health. These two cohorts, referred to as the 2005 Cohort and 2006 Cohort, were followed up three times every two years. This data set was referred to as the Children's Health and Environmental Research (CHEER) data set. This paper reproduces the existing research results of Kim et al. (Journal of the Korean Data and Information Science Society, 25, 987-998, 2014) and Lee et al. (The Korean Journal of Applied Statistics, 29, 1295-1310, 2016) and derive a benchmark dose lower limit (BMDL) for blood lead level for attention deficit hyperactivity disorder (ADHD) after pooling two cohort data sets. The different ADHD rating scales were unified by applying the conversion formula proposed by Lee et al. (2016). The random effect model and AR(1) model were built to reflect the longitudinal characteristics and regression to the mean phenomenon. Based on these models the BMDLs for blood lead levels were derived using the BMDL formula and the simulation. We obtained a hight level of BMDLs when we pooled two independent cohort data sets.

Objectives: One major limitation encountered in retrospective exposure assessment for epidemiological study is the lack of exposure records and information maintained by companies which if they existed would allow the estimation of past exposure to hazardous operations and agents. This study developed a job-specific questionnaire(JSQ) to estimate exposure profiles among semiconductor workers, including operation and job. Methods: This JSQ can be directly applied to workers who work or have worked in a wafer fabrication or a chip packaging and assembly facility. Results and Conclusions: We used this JSQ to obtain past exposure information from semiconductor workers via face-to-face investigation. Major contents include questions on the facilities, operations and jobs to which they have been exposed since they entered employment in the semiconductor industry. The total number of questions in the JSQ is 18. Responses to this JSQ can be used not only to estimate retrospective exposure to operations and jobs in the semiconductor industry, but also to associate with the risk of all causes of death and risk of disease, including cancer.

Jain-Danoje's course since modern is not different with almost all of folk performances, which were restored and reconstructed with a background of the designation of an intangible cultural heritage and National folk arts contest sine the 1960s. Generally, these folk performances were decontextualized in course of extinction and reappearance, and recontextualized in course of new directions on tradition. Also, the performances were interpreted differently and transformed by the main constituents of reappearance. Jain-Danoje nowadays has a regular form just at that time that has been designated as a cultural heritage at 1970s. But, today's Jain-Danoje is clearly different with the last appearance in 1936 and some Literature and jainhyun-eupji. I think such differences would stems from the process of reproduction. From this perspective, I had investigate Old literature and the early days report, and the current text. Especially, I will show the considerable change which has been occurred in the Yeowonmu and Hojanggut, the central role to configure that identity, by comparing past and today. As a result of consideration, today's form of the Yeowonmu and Hojanggut are created texts that mind the designation of an intangible cultural heritage and National folk arts contest. These texts has been reproduced without understanding about structure and current of folk festival and state of performance which has been transmitted on premodern society. some intellectuals search for an archaic form of Jain-Danoje based on jainhyun-eupji that created in 1895, except the other jainhyun-eupji. Moreover, because of the understanding with a bias, they can't grasp the meaning about the religious service for Hanjanggun, and they can't see the facts of Yeowonmoo. In addition, they were aware of 'o-sin' that led by Hojang as a fancy dress parade in a carnival, and that is recognized as a component of Jain-Danoje, so there was other text which is different from our own festival.
