천장관절 기능이상과 요통증

임성수,Lim, Sung-Soo 대한물리치료과학회 1999 대한물리치료과학회지 Vol.6 No.3

The hub of weight bearing in the human body for both static and dynamic activities is the lumbopelvic region. It is a key region of extraordinary stability, since the trunk and ground forces converage in this region. The two sacroiliac joints form an integral part of this lumbopelvic unit. Considerable effort has been expended to study and quantify the normal range of movement of the sacroiliac joints Mitchell suggests that the ilium rotates in a posterior direction at heel strike and progresses in an anterior direction as the individual passes through the stance phase. The overall key appears to lie in determining the weight-bearing pattern of the sacroiliac (lumbopelvic) region from above and below that results in the familiar pain of sacroiliac dysfunction, assessing the status of the injured tissues, and intervening with the proper treatment protocols that maximize the body's healing processes. The purpose of this chapter is to provide a comprehensive overview of the sacroiliac joint's tissues and biomechanics, as well as concepts of evaluation and treatment. This overview is aimed at assisting the clinician in identifying the forces that are potentially destructive to the lumbopelvic tissues.

Optimizing Food Processing through a New Approach to Response Surface Methodology

임성수 한국축산식품학회 2023 한국축산식품학회지 Vol.43 No.2

In a previous study, ‘response surface methodology (RSM) using a fullest balanced model’ was proposed to improve the optimization of food processing when a standard second-order model has a significant lack of fit. However, that methodology can be used when each factor of the experimental design has five levels. In response surface experiments for optimization, not only five-level designs, but also three-level designs are used. Therefore, the present study aimed to improve the optimization of food processing when the experimental factors have three levels through a new approach to RSM. This approach employs three-step modeling based on a second-order model, a balanced higherorder model, and a balanced highest-order model. The dataset from the experimental data in a three-level, two-factor central composite design in a previous research was used to illustrate three-step modeling and the subsequent optimization. The proposed approach to RSM predicted improved results of optimization, which are different from the predicted optimization results in the previous research.

17~18세기 訓鍊都監 給料와 三手米의 운영

임성수 고려사학회 2020 한국사학보 Vol.- No.80

The study is about the military system and salary of Hullyeon- Dogam(訓鍊都監). Hullyeon-Dogam(訓鍊都監), which was created in the midst of an urgent war, was operated with the support of the government without a financial foundation. The government collected additional land taxes(三手米) from 1602 for wages. The number of soldiers who were initially 3,000 surged to 8,500 per year for King Injo and King Hyojong, resulting in a shortage of resources ranging from about 15,000 to 30,000 bags(石) of rice a year. Thus, the reduction was discussed, and in 1671, some units were abolished, saving 10,000 bags of rice and 200 rolls of cotton annually. In 1682, the total salary was reduced to 40,000 bags by reducing the number of troops to 5,000 through the reorganization of the military. In 1758, the additional pay(兼料) system was also changed. The additional pay paid to the concurrent soldiers was as high as 3,870 bags of rice a year and 7,377 bags of millet. The government used the millet of Hwanghae(黃海道) and Pyongan(平安道) provinces to reduce rice spending, which had been a key source of financial resources, and to get out of the responsibility for the additional pay. Reducing the number of soldiers and improving the additional pay system made it easy for the government to pay the military salaries. Nevertheless, the government implemented a policy to increase income by expanding land taxes. In 1760, the government also imposed taxes (三手米) on land that was tax-free, resulting in more than 5,000 bags of rice and 1,200 bags of millet. Taxes in the mid- to late 18th century were a key source of taxation, accounting for more than 46 percent of the government's rice imports.

A Single-Plot Visualization of the Relative Importances of All Factors in Optimizing the Response

임성수 한국자료분석학회 2006 Journal of the Korean Data Analysis Society Vol.8 No.5

Two typical objectives of response surface methodology(RSM) are, first, to determine the optimum combination of factor levels, and second, to gain understanding of the characteristics of the response system. This article proposes a graphical display to serve that second objective of RSM. Here, the partial effect of factor j is defined as the effect of factor j when the levels of the other factors are fixed at their optimum values. The partial effects plot is a plot that shows, for j=1,...k, how the response moves as the level of factor j changes in the design region when the levels of the other factors are optimal. This plot allows graphical comparative assessment of partial effects of the factors, and so we can graphically find out which factors are relatively more important in optimizing the response and which factors are not so. A real data set from a lettuce cultivation experiment was used for illustration.

균형 다요인 자료에의 주 효과 모형 적합시의 반응값 재표현

임성수,진서훈 한국자료분석학회 2008 Journal of the Korean Data Analysis Society Vol.10 No.1

Some literature on experimental design and analysis contains, in its parts on analysis of a factorial experiment, boxplots placing the levels of each factor on the horizontal axis and the response values on the vertical axis. Such boxplots do not seem appropriate since the response in a factorial experiment can be under the influence of multiple factors and thus they may not be able to show the individual influence of the factor placed on the horizontal axis upon the response. Using the method this research proposes, these boxplots can be replaced by appropriate ones. This article proposes a method to reexpress response values when fitting a main effects model to balanced multifactor data. The purposes of this method are to evaluate and visualize the influence of each factor upon the response mean and response variation, and to determine the optimal levels of each factor for either maximization or minimization of the response mean and minimization of response variation. This method has been developed using the concept of the residual in a linear model. A case study illustrates an application of this method to real data by the use of an appropriate statistical package. 실험설계 및 분석에 관한 문헌 중에는 다요인실험의 분석 부분에 각 요인에 대해 가로축에 요인 수준값, 세로축에 반응값을 놓는 상자그림들이 등장하는 것이 있다. 이러한 상자그림들은, 다요인실험에서의 반응은 다수 요인들의 영향을 받을 수 있으므로, 가로축에 놓인 요인이 반응의 산포에 주는 개별적 영향을 나타낸다고 할 수 없어 적절하지 않은 것으로 보인다. 본 연구가 제안하는 방법을 사용하면, 이러한 상자그림들을 적절한 상자그림들로 대체할 수 있다. 본 논문은 균형 다요인 자료에 주 효과 모형을 적합시킬 때의 반응값 재표현 방법을 제안한다. 이 방법의 목적은 반응의 위치와 산포에 대한 각 요인의 개별적 영향을 평가하고 시각화하며, 반응평균의 최대화 또는 최소화 및 반응변동의 최소화를 고려하여 각 요인의 최적 요인수준을 결정하는 것이다. 이 방법은 선형모형에서의 잔차의 개념을 이용하여 개발되었다. 사례 연구에서 적절한 통계 패키지의 사용에 의한 이 방법의 실제 자료에의 적용을 예시한다.

17~18세기 과세지 확대와 宮房田 규제 강화

임성수 서울대학교 규장각한국학연구원 2019 한국문화 Vol.0 No.87

Joseon Dynasty managed national finance based on land tax. After Japanese invasion of Korea, land was nationally abandoned, financial base became weak, and all of institutions including hojo strived to secure of taxation sites. Among them, royal institutions expanded self-managing lands with jeolsuje(折受制). Especially, royal finance included lots of lands farmed newly while actually cultivating wasteland. In other words, gungbangjeon(宮房田) was tax-free land(免稅地), so it was a big burden to secure taxes of central government as the scale increased. Therefore, the court prepared regulations to restrict the scale of tax-free gyeol in 1663. But, tax-free gyeol was continuously increasing because of the gungbang exceeding the restricting regulation and appearance of new gungbang. In 1695, tax-free gyeol getting out of the regulations was returned, hojo provided wonjeon(元田) 200 gyeol(結) to new gungbang, gungbangjeon preparation was changed to the type purchasing insufficient tax-free gyeol. Because of the measure, jeolsuje was abolished, but returning of gungbangjeon getting out of the regulations was insufficient. Finally, in 1776, a measure that husa(後嗣) was not existing, tax-free gyeol passing 4 generations(代) was collapsed, and gungbangjeon getting out of the regulations was conducted. Due to the measure, total 31 daejinㆍmuhugungbang were collapsed and 11,212 gyeol possessed by several gungbang was changed to taxation site.
