  • In Korea there is no specific method of age adjustment in noise induced hearing loss(NIHL). We attempted the age adjustment to understand the effects of age on the diagnosis of NIHL. We used the International Standard Organization 1999 as an age adjustment method. We used the 1, 617 otologically normal person's hearing data from a health examination center, and 206 workers diagnosed as NIHL. We concluded as follows; 1. The ISO 7029 function used for age specific hearing loss is not suited to Korean people. 2. The mean of age specific hearing loss is 11.0 6.2dB and the older of age, the more decrease on hearing loss, especially in 4000Hz. 3. The difference of NIHL between before age adjustment and after age adjustment in the 3rd decade is 5.4dB, in the 4th decade is 6.7dB, in the 5th decade is 8.5dB, in the 6th decade is 10.4dB, and in the 7th decade is 12.9dB. The older, the more is the difference. 4. After age adjustment, the number of workers diagnosed as NIHL decreases to 60% of unadjusted.

  • Objectives This case study is about a Soeumin patient with jaundice identified as Greater-Yin accompanied Jaundice pattern. In this study, we report significant improvements of anorexia, dyspepsia, fatigue and weight loss after treatment with Hyangsayangyi-tang, Insambaekhaogwanjung-tang and acupuncture.Methods The patient was identified as Greater-Yin accompanied Jaundice pattern and treated with Hyangsayangyi-tang, Insambaekhaogwanjung-tang and acupuncture. The Global Assessment Scale (GAS) was used to assess the improvements of anorexia, dyspepsia, fatigue and pelvic pain after the treatment. And the liver function test was performed to measure the overall function of the liver.Result and Conclusion The symptoms of anorexia, dyspepsia, fatigue and pelvic pain were improved from GAS 100 to GAS 0-10 for four months. And The liver function test showed improved the response to treatment. The levels of AST (aspartate aminotransferase)/ALT (alanine aminotransferase) decreased from 43/42 to 29/14 IU/L. The level of total bilirubin was decreased from 2.7 to 1.9 mg/dL. Furthermore total weight gain was 8 kg from starting weight of 36.5 kg for four months. In conclusion, this study shows that Sasang constitutional medicine can be effective and safe treatment for the Soeumin patient with jaundice.

  • 본 논문에서는 사상 체질 분류를 음성 분석 정보값의 비교, 분석을 통해 제안하고자 한다. 이를 위해 본 논문에서는 사상체질의 객관적 지표를 마련하기 위한 전체 시스템 구성 중 1차 단계로써 피부 진단을 통한 소음인의 분류 과정과 연계하여 음성 신호 분석에서 발생하는 정보의 출력값에 의해 태음인을 분류하는 방법을 제안하고자 한다. 우선 각 사상 체질별로 뚜렷한 특징을 보유하고 있는 집단군을 구성하고 이들의 음성 특성을 분류하여 음성학적 요소를 추출하고자 한다. 또한 출력된 결과값을 토대로 체질 집단별 차이점과 유사점을 통하여 태음인을 분류하고자 한다. 끝으로 실험에 의해 제안한 방법의 유용성을 입증하고자 한다.

  • 반도체 소자 제조 공정에 사용되는 공정 펌프는 전체 소요되는 에너지(소비전력)에 52%를 소비하고 있다. 이러한 이유 때문에 반도체 fab 내에서 에너지 절감을 논의할 때 항상 공정용 진공 펌프가 1 순위에 오를 수밖에 없는 것이다. 반도체 공정용 진공 펌프는 사용되어지는 공정에 따라 유지되는 진공도가 달라지고 이에 따라 소비전력과 투입되는 utility의 양이 바뀌게 되어 진공도와 공정에 따른 에너지 소비의 pattern이 다르다. 한국표준과학연구원 진공센터에서는 각 공정 대응용 펌프의 종류에 따라 배기속도, 도달진공도, 소비전력, 진동, 소음 등 기본 펌프 성능 평가, light gas인 helium에 대응하는 기본 성능평가를 실시하고 있다. 또한 부가적으로 soft/medium 공정용의 경우 저전력 mode의 소비전력의 진공도에 따르는 측정변수의 pattern을 측정/분석하고 있으며, harsh 공정용의 경우 50~300 slm의 유량 주입에 따른 내구성 특성을 monitoring하고 있다. 드라이펌프의 기본적인 평가 성능과 각 회사의 SPM (single pump monitoring system) 측정 변수인 온도, 배기구 압력 변화 등의 자체 진단 인자를 포함하여 반도체 공정에서 드라이 펌프의 운용에 필요한 냉각수, $N_2$, 등과 같은 utility의 사용량 및 온도변화 등을 측정하여 드라이 펌프의 에너지 소비 pattern을 분석하고자 한다.

  • Objective This study was devised to create a new diagnosis and an assessment index by Soeumin's Ordinary Symptoms. Method First, a Working Committee and an Advisory Committee were formed for development, and the development goals were set. Then, the Soeumin's disease diagnosis indicators were extracted from the previous Clinical Practice Guidelines for Sasang Constitutional Medicine. To increase the clinical applicability, the extracted diagnosis indicators were focused on ordinary symptoms, and translated into Korean. The translated diagnosis and assessment indicators for Soeumin were surveyed to the Advisory Committee using the Delphi technique, and the inclusion, importance, and validity of each indicator were investigated accordingly. Result The translated diagnosis and assessment indicators were finally revised based on the surveyed inclusion and translation validity opinions, and the weight of each indicator was set based on the investigated importance, and a draft of the diagnosis and assessment index was developed. Conclusion This developed index can help to make effective diagnose about Soeumin's diseases by clinical doctor. In the future, a clinical study of this index can be conducted to consider the reliability, validity, and cut-point, and through this process, the actual clinical applicability will be improved.

  • Objectives The purpose of this case study was to report that San-syndrome patient was treated by diagnosing as Greater Yang Disease Reverting Yin Pattern. Methods The patient was administered with Insamosuyu-tang. Numeral Rating Scale (NRS) and National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) was used to assess the improvements of symptoms. Results and Conclusions The perineal region discomfort was reduced from NRS 4 to NRS 1. NIH-CPSI score was reduced from 23 to 11, which means symptom relief. Nocturia and sleep disorder were resolved, and general weakness was relieved accordingly.
