윤지현,정재윤,Yoon, Ji Hyun,Jung, Jae-Yoon 한국빅데이터학회 2017 한국빅데이터학회 학회지 Vol.2 No.1

6시그마는 지난 20여 년간 제조 및 서비스 등의 산업에서 프로세스 개선을 위하여 꾸준히 적용되어왔다. 그럼에도 불구하고 6시그마는 Define 단계에서 의미있는 프로젝트를 계속 발굴하기 힘들고 Control 단계에서 지속적인 측정 및 통제가 쉽지 않다는 문제가 지적되었다. 이를 해결하기 위하여 개선 프로세스의 지속적인 통제와 관리를 원활히 할 수 있는 체계가 요구되며, 비즈니스 프로세스 관리(BPM) 시스템이 효과적 대안이 될 수 있다. 본 연구에서는 프로세스 운영 및 분석에서 누적된 데이터를 중심으로 지속적 프로세스 개선을 실현하기 위한 목적으로 6시그마와 BPM의 통합 모형을 제시하고, 프로젝트 수행을 위하여 상호 데이터기반으로 프로세스를 분석, 개선, 모니터링하는 과정을 설명한다. 이를 통하여 6시그마와 BPM의 장점을 결합하여, 지속적으로 업무를 개선하고 관리함으로써 전사적인 경영성과를 극대화할 수 있을 것으로 기대한다. Six Sigma has been adopted for the last two decades in many industries of manufacturing and service business to implement processs improvement. The methodology has difficulties in discovering target projects in the Define step and in controlling continuous measure and control in the Control step. To address the problem, more advanced system is required to support continuous control and management, and business process management (BPM) can be an effective solution for this problem. In this research, we introduce integrated models of Six Sigma and BPM for the purpose of realizing continuous process improvement, and explain the procedure of analyzing, improving, and monitoring the processes based on the data which has been accumulated in business process execution. It is expected that this integrated approach can maximize business performance by improving and managing business continuously on the integrated platform of two business innovation strategies, Six Sigma and BPM.

Objective: The purpose of this study is to report the effects of warm needling in a patient with cancer who had chemotherapy-induced peripheral neuropathy (CIPN). Methods: A 46-year-old Korean female outpatient diagnosed with malignant ovarian cancer was treated with warm needling therapy on the foot acupuncture points for CIPN. Neuropathic symptoms and quality of life were assessed using the numeric rating scale (NRS) and the functional assessment of cancer therapy/Gynecologic Oncology Group neurotoxicity (FACT/GOG-NTX) score. Results: After 6 months of treatment, the patient showed a reduction in the severity of CIPN symptoms and an improvement in the quality of life, although the severity of symptoms fluctuated as the patient underwent chemotherapy sessions. Conclusion: This study suggests that warm needling may be an effective treatment for CIPN.

Objective: Constipation is the most common adverse effect of opioid analgesic therapy in cancer patients. This can be associated with physical and emotional distress to cancer patients. The purpose of this study is to review the standard and alternative interventions of the management for opioid-induced constipation (OIC). Methods: The studies were searched from databases, including Pubmed, Google scholar, KISS, NDSL, and OASIS. The main search terms included such as constipation, opioid, opioid-induced constipation, cancer, management, herb, and acupuncture. Results: The prevention and usual care of constipation is a key tool for the management of OIC. Also, prophylactic laxatives starting concurrently with opiates helped to prevent developing constipation. Peripherally acting μ-opioid receptor antagonists (PAMORAs) significantly reduced OIC and well-tolerated. In addition, acupuncture, herb medicines, and interferential current or transcutaneous electrical nerve stimulation to acupoints had effectiveness in reducing constipation. Conclusion: Preliminary data indicate that PAMORAs and Traditional Korean Medicine may be considered as the management of unresolved OIC. However, due to the limited articles, more systematic and rigorous clinical trials are needed.

Objective: This study aimed to evaluate which information of cancer patients should be collected for the Korean medicine cancer registry in order to assess the efficacy and safety of Korean medicine (KM) treatment and to identify Korean medical prognostic predictors. Methods: A total of fifteen Korean medical specialists completed an online survey questionnaire including items about general characteristics of cancer patients and clinical practice patterns. Results: The four main types of cancer at Korean medical hospitals were breast, lung, stomach, and colorectal cancer. The majority of patients with cancer at Korean medical hospitals were in the advanced or metastatic stage (50.0%). The prominent purposes of KM treatment were to alleviate cancer-related symptoms, reduce the side effects of conventional therapy, and improve quality of life. The major options for treatment were traditional herbal medicine (THM), acupuncture, moxibustion, thermotherapy, pharmacoacupuncture, and meditation, with THM being the most frequently used (35.7%). Almost all Korean medical specialists (93.9%) used syndrome differentiation in clinical practice and identified over half the cancer patients as deficiency syndrome (57.2%). Conclusion: Physicians considered the primary goal of KM treatment for cancer patients to be symptom management since advanced or metastatic stage patients were the majority at Korean medical hospitals. THM were the most common treatment option and syndrome differentiation was used by almost all physicians. Further research is needed to monitor and ensure optimal KM treatment for patients with cancer.

본 연구에서는 시멘트와 광물질혼화재인 고로슬래그미분말과 플라이애쉬를 미리 혼입한 Premixed Cement를 사용한 콘크리트와 수축저감제가 혼입된 3성분계 콘크리트, OPC 100%의 콘크리트에 대하여 기초물성 평가로 공기량, 슬럼프, 압축강도 및 건조수축 시험을 수행하고, 수화열 해석을 수행하여 Premixed Cement를 사용한 콘크리트의 현장 적용성을 검토하였다. 검토결과 Premixed Cement를 사용한 콘크리트는 목표 작업성 및 설계기준압축강도를 충분히 만족하며, 건조수축 측면에서도 수축 저감제를 혼입한 3성분계 콘크리트와 유사한 건조수축 특성을 나타내었다. 또한, 수화열 해석 결과 Premixed Cement를 사용한 콘크리트는 목표 온도균열지수를 충분히 확보할 뿐만 아니라, 수축 저감제를 혼입한 3성분계 콘크리트보다 경제성을 확보할 수 있는 방안으로 도출되었다. 향후 매스콘크리트구조물 시공에 있어 구조물의 내구성능 및 유지관리 편의성 향상을 위해 Premixed Cement를 사용한 콘크리트의 현장적용은 바람직한 것으로 판단된다. This study carried out to evaluate the hydration heat analysis and fundamental characteristics such as air content, slump, compressive strength and dry shrinkage according to concrete with premixed cement, ternary concrete and OPC concrete for using concrete with premixed cement. The results of experiment are founded that concrete with premixed cement have sufficient performances such as workability, compressive strength and dry shrinkage. Also, the results of hydration heat analysis are founded that concrete with premixed cement have more performance than ternary concrete and OPC concrete at a point of view for the quality control such as thermal crack reducing and economic benefit. Therefore, it is desirable that concrete with premixed cement should be used to rise durability performance and convenience of maintenance.

The fracture toughness of 2.25Cr-1Mo cast steel (SA217-WC9) samples which were taken from the check valves of feed water piping of Korean Standard Nuclear Power Plant(KSNPP) was measured by Master Curve method. The measured $T_0$ reference temperature of SA217-WC9 steel was $-30^{\circ}C$. The obtained $T_0$ was compared to the derived value from Charpy impact test data following to SINTEP procedure. The heat-to-heat variation in fracture toughness of SA217-WC9 steel was observed. It was found that the low toughness of a heat of SA217-WC9 steel was attributed to the coarse MnS inclusion originated by high sulfur content as the results of microanalyses.

This study aims to develop a maker education-based experimental design program and explore its effects as a strategy for developing experimental design competency of secondary science pre-service teachers. Therefore, experimental subjects were selected and programs were developed to design experiments based on maker education. The developed program was applied to 29 pre-service teachers. In addition, in order to analyze the effect of the developed program on the experimental design competency of pre-service teachers, the test was conducted using DCT. And post-interviews were conducted after applying the program. As a result of applying the program, it was confirmed that the pre-service teachers repeatedly performed the steps of cycled through the experiment design process. In addition, as a result of analyzing the change in the experimental design competency, it was found that the overall experimental design competency of pre-service teachers has increased statistically. And the analysis of pre-service teachers overall perception showed that the visibility and flexibility of the maker education led to a cycle of the experimental design process , the use of sensors has a positive effect on the hypothesis setting stage , building confidence in experimental design activities and will to apply the maker s education-based experimental activities in the field of one s major or educational field . The educational implications for this were discussed.
