Manual therapy has undergone parallel development throughout many parts of the world dating back to ancient times for at least 2,500 years. The earliest historical reference to the practice of manual therapy in Greece, dates back to 400 B.C. Over the centuries, manual medicines have fallen in and out of favor with the medical profession. To truly understand the principle, it is important to know that manual therapy was initially the mainstay of the three leading alternative health care systems, osteopathy, chiropractic, and most notably physical therapy. These were all founded in the latter part of the 19th century in response to the shortcomings in allopathic medicine. Although it has been around for a long time and has been used all over the world, there are a few reports on manual therapy treatment, and most papers provided a low level of evidence. Despite the controversies over manual therapy, its use appears to be increasing gradually. This article reviews the history of manual therapy from ancient times to the present including Korean history, discusses the current state of knowledge on manual therapy, and informs physicians who manage musculoskeletal pain.

Objective : To provide a foundation to develop clinical training program based on a status of sensory integration therapy in Korea identified through the study. Methods : A questionnaire has been developed that is investigating such as environment of therapy, level of knowledge of therapist, and etc. The questionnaire was distributed from June 1st,2014 June 1 to August 31st,2014. The total questionnaire result collected and analyzed are 232 responses. Results : In terms of ratio of therapist who are administrating sensory integration, occupational therapist takes biggest percentage. In most case, it is equipped enough to do treatment in terms of space and tools. Generally, therapists are performing evaluation and documentation earnestly, and willingly participating to continued education and clinical training coursework. However, it is found that some cases are implementing treatment without through evaluation and/or without professional training. Conclusion : This study propose that sensory integration therapists need to train their clinical knowledge and skills through professional training education based on the Ayres Sensory Integration (ASI) theory. Most of professional trainings are administered in capital area currently. The educational opportunities need to be extend to outside of capital region so the level of clinical competence and the quality of the therapy service can be improved.

Gene expression data present the level of mRNA abundance of each gene, and analyses of gene expressions have provided key ideas for understanding the mechanism of diseases and developing new drugs and therapies. Nowadays high-throughput technologies such as DNA microarray and RNA-sequencing enabled the simultaneous measurement of thousands of gene expressions, giving rise to a characteristic of gene expression data known as high dimensionality. Due to the high-dimensionality, learning models to analyze gene expression data are prone to overfitting problems, and to solve this issue, dimension reduction or feature selection techniques are commonly used as a preprocessing step. In particular, we can remove irrelevant and redundant genes and identify important genes using gene selection methods in the preprocessing step. Various gene selection methods have been developed in the context of machine learning so far. In this paper, we intensively review recent works on gene selection methods using machine learning approaches. In addition, the underlying difficulties with current gene selection methods as well as future research directions are discussed.

The purpose of this study was to investigate the perception and satisfaction on the nutrition counseling service for patients consuming a therapeutic diet at hospitals in Busan. The subjects were 153 inpatients at five hospitals with over 400 beds each. The research was performed through the interviewing process using questionnaires conducted from January to February, 2008. In a total of 88 patients, 57.5% had experienced nutrition counseling and were through the motives of counseling with doctors 64.2% and themselves 29.3% of the patients. In the method of nutrition counseling, 58% of the patients had an individual counseling. In the patients' perception on the nutrition counseling, 75.0% of the patients understood very well, 83.0% of them perceived the explanation as very important, 79.5% were very satisfied and 78.7% were helped in nutrition-management. On a scale of 5.00 for the nutrition counseling satisfaction, the average scores were 3.80 for 'explanation of knowledge', 3.71 for 'cognitive communication skills', 4.05 for 'effective communication skills' and 3.60 for 'facilitation skills'. The items of low scores in the nutrition counseling satisfaction were 'follow up diet-therapy after discharge', 'providing to personalized nutrition information', 'presentation of specific menu' and 'methods of menu planning'. There were significant (p<0.01) positive correlation between perception and satisfaction on the nutrition counseling. Therefore, it was suggested that dietitians increase the patients' satisfaction on the nutrition counseling with developing the model based on the patient-centered counseling.

목적 : 세기변조방사선치료의 정도관리 중 선량 분포의 비교에 관한 새로운 정량적인 방법을 제시하였다. 이 과정 중에서 선량의 기울기가 큰 영역에서의 문제점을 해결하기 위하여 최적화 알고리듬을 사용하였다. 대상 및 방법 : 필름을 통해 측정된 선량분포와 컴퓨터를 통해 구해진 선량분포를 각각 5mm 간격과 lmm 간격의 해상도로 컴퓨터를 이용해 2 차원 선량분포로 구현한다. 그 후 두 선량분포사이의 차이를 각 선량분 포의 원점을 일치시킨 후 구해낸다. 이때 일반적으로 두 선량분포 사이의 차이는 선량의 기울기가 큰 영역에서 상당히 크게 나타나게 되는데 이것은 측정 장비의 원점을 구하는 과정에서 발생되는 이차원 상의 미세한 원점의 불일치 효과로 선량의 차이가 선량의 기울기가 큰 영역에서 더욱 커지기 때문이다. 이 불일치를 보정하기 위해서, 측정된 선량분포를 계산된 선량분포 위에서 lmm 간격으로 이동시켜가면서 선량의 차이를 계산하여 이 값이 최소가 되는 위치를 확인한다. 이때의 이동치는 가속기가 갖는 허용오차 이내에 있어야 하며 이 값은 2mm로 알려져 있다. 이 과정과는 독립적으로 이온 챔버를 통해 측정된 절대선량 값을 이용하여 두 선량분포 사이를 재 규격화한 뒤 차이를 구하게 되면 우리는 5mm 간격의 2 차원 절대선량 분포 비교를 실험상의 오차들 중 가장 크게 작용하는 원점 오차로 인한 오차를 제거한 뒤 수행한 것과 같은 결과를 얻게 된다. 여기서 계산된 선량분포의 해상도는 장비의 허용오차 보다 항상 작아야 한다. 결과 : 머리와 목에 환부를 갖는 여러 환자들에 대한 선량분포 비교 결과를 통해서, 측정된 선량분포와 계산된 선량분포사이의 허용오차 범위에 대한 일시적 기준을 마련하였다. 이 기준은 물론 더 많은 환자들에 대한 선량분포 비교를 통해 개선되어질 수 있다. 결론 : 측정 장비의 원점 불일치의 보정뿐만 아니라 측정 장비의 회전에 의한 오차 보정, 필름의 광학적 밀도에 관한 보정 등 여러 가지 계통적 오차들에 대한 보정들이 선량분포 확인과정의 이해와 그 기준마련에 도움이 되겠지만 우리가 다룬 원점 불일치에 비해서 상대적으로 무시할 수 있었다. 마지막으로 선량분포 확인의 최종목표인 3 차원 선량분포 확인의 실제 적용을 위한 연구가 최적화 알고리듬을 이용하여 실험 중에 있다.

소아들의 음성장애의 대부분은 음성과 기능에 의한 성대의 오용 및 남용으로부터 기인한다. 그러나 음성장애에 대한 인식의 부족으로 인하여 소아의 음성장애 발견율은 극히 낮은 수준에 머므르고 있다. 치료에 있어서도 행동의 통제가 그다지 쉽지 않기 때문에 많은 어려움이 따른다. 본 연구는 소아의 음성장애의 발생경위와 문제의 설명과 차팅에 의한 남용의 감소에 초점을 둔 치료사례이다. 5세 아동의 심한 음성장애로 의뢰되어졌다. 음성증후는 목쉰소리, 기식화된 소리, 일시적인 발성일탈(phonation break) 등이 두드러졌다. 이비인후과 전문의의 스트로보스코프(stroboscope) 검진결과 초기 양측성 성대결절이 성대 앞쪽으로부터 1/3 지점에서 발견되었으며 비지피치(Visi-Pitch)로 측정된 퍼터베이션(perturbation 수치가 16.8이었다. 사례사 조사 과정에서 아동이 활동적이며 자주 고함을 지르고 자동차놀이를 주로하며 많은 시간을 보낸다는 것이 밝혀졌다. 중재 프로그램은 우선 문제를 설명하고 인식시키는 것과 고함을 지르거나 자동차놀이를 하면서 자동차 소음을 흉내내는 등의 음성남용 회수를 감소시키는 것에 초점을 두었다 17회의 치료로 성대결절이 감소되었고 퍼터베이션은 3.8로 저하되었으며 아동 스스로 음성남용을 통제할 수 있다는 임상적 판단하에 치료를 종결하였다. 1개월 후 추후 검사에서 남용적인 습관이 여전히 나타나지 않았으며 음성상태도 양호하였다. 소아 음성장애의 치료는 소아가 이해할 수 있는 용어로 문제의 인식을 확실히 시키고 행동을 체계적으로 통제할 수 있는 치료프로그램을 실행시키는 임상가의 자질이 대단히 중요하다. 그러나 그에 못지 않게, 많은 시간을 아동과 함께 보내는 부모나 교사의 협력이 치료의 성패를 좌우할 수 있다.조구와 처리구간에 차이가 없었다. 그러나 유지방 함량의 경우 대조구가 3.22%, 처리구가 3.37%로 처리구가 0.15% point 증가했으나 유의차는 없었다.

Problems in feeding habits could affect various aspects of children including growth, learning, communication, interaction with other children, etc. Oral consumption was defined as a participant opening his/her mouth, accepting food/liquid, and swallowing. A goal of the study is to find a method of evaluation and intervention of a child's feeding habits. Feeding is an important component in the early development of children and may have later consequences in the child's ability to participate successfully in their activities of daily life. Children show personal difference on the foods which they try first because stimuli from the foods are revealed as a mealtime behavior through sensory registration and processing. Feeding problems in sensory processing consist of tactile oversensitivity, oral refusal, tactile undersensitivity, and oral dyspraxia. In order to identify problems of sensory processing among feeding difficulties and plan intervention, the understanding of neurological processing and sensory processing characteristics related to feeding is necessary. Reviewing intervention for feeding problems related to sensory processing is required for an effective approach for feeding and providing better life for children.

We studied a Monte Carlo simulation of the proton beam delivery system at the National Cancer Center (NCC) using the Geant4 Monte Carlo toolkit and tested its feasibility as a dose verification framework. The Monte Carlo technique for dose calculation methodology has been recognized as the most accurate way for understanding the dose distribution in given materials. In order to take advantage of this methodology for application to external-beam radiotherapy, a precise modeling of the nozzle elements along with the beam delivery path and correct initial beam characteristics are mandatory. Among three different treatment modes, double/single-scattering, uniform scanning and pencil beam scanning, we have modeled and simulated the double-scattering mode for the nozzle elements, including all components and varying the time and space with the Geant4.8.2 Monte Carlo code. We have obtained simulation data that showed an excellent correlation to the measured dose distributions at a specific treatment depth. We successfully set up the Monte Carlo simulation platform for the NCC proton therapy facility. It can be adapted to the precise dosimetry for therapeutic proton beam use at the NCC. Additional Monte Carlo work for the full proton beam energy range can be performed.
