Purpose: This paper provides an idea on the future prospect for change in steps of the six sigma DMAIC project under the environment of the 4th industrial revolution. Methods: First, the purpose and activities required in each step of DMAIC are reviewed. Next, activities are reviewed together with tools and techniques, considering the purpose and the environmental changes of the 4th Industrial Revolution. Finally, the best approaches for achieving the purpose are prospected to get an idea on future change. Results: The purpose of each phase of DMAIC is expected to remain unchanged. But activities, techniques, or methods will be replaced with more effective and efficient ones. Also, many activities may possibly be executed by a system instead of people like BB, GB or team members. Moreover, DMAIC may not be a project any more but a routine job of the system in the future. Conclusion: Under the environment of the 4th industrial revolution, many activities including analyzing various types of data and extracting valuable information, will be executed by a system with proper algorithms instead of people. And six sigma improvement projects may be intrinsic parts of the system and may not exist as separate projects any more.

지난 논문에 이어서 삼중수소 취급시설의 일부인 삼중수소 주입계통과 재생계통을 소개하였다. 두 계통은 모두 삼중수소의 유출이 가능한 계통들로서 GB안에 설치되어야 하는 계통들이다. 삼중수소 주입계통은 삼중수소 취급시설을 사용하여 목적하는 제품을 생산하게 되는 주 계통으로서 삼중수소의 관리를 위하여 정확히 삼중수소의 주입/분배량을 계량할 수 있어야 하고, 주입 후 계통내 잔여 삼중수소를 최대한 회수할 수 있도록 하여 방사성 물질의 환경방출을 최소화 할 뿐만 아니라 귀한 자원의 손실을 최소화하도록 설계되었다. MS, Ni catalyst bed, metal getter 등 재생이 필요한 TRS 내부의 장치들은 별도의 재생계통을 사용하여 재생한다. 다른 장치들의 재생은 장치를 가열하면서 적절한 purge gas를 흘려주는 비교적 간단한 방법으로 재생이 가능하나 삼중수소를 흡착한 metal getter의 삼중수소를 회수해야 하기 때문에 복잡한 공정을 거쳐야 한다.

Objectives: The purpose of the study is to investigate the factors associated with gingival bleeding(GB) by tooth brushing in college students. Methods: A self-reported questionnaire was filled out by 232 college students in Daegu Health College from March to June, 2014. Data were analyzed for frequency, chi square test, and logistic regression analysis using SPSS 12.0 program. The study was a cross sectional study. The questionnaire consisted of general characteristics of the subjects(gender, age, marital status, and smoking), frequency and duration of tooth brushing, scaling experience, and physical health status. Self-reporting hemorrhage was reported by yes or no. Frequency of tooth brushing was documented as the number of behavior. Above 4 times of tooth brushing was defined as 4. Duration of tooth brushing was documented as minute. Above 4 minutes, it was recorded as 4. In physical health status, 1 is feeling weak and 4 is feeling very healthy. Cronbach alpha was 0.82 in the study. Results: There were significant relationships between gingival bleeding and age(p<0.05), subjective health(p<0.01), tooth brushing frequency(p<0.05) and duration(p<0.05) by chi square test. Logistic regression analysis showed that the age(p<0.05), subjective health(p<0.01), tooth brushing frequency(p<0.05) and duration(p<0.05) were associated with gingival bleeding. Prevalence of gingival bleeding in 20 years was 0.62(odds ratio 1.85, 95% CI 1.00~3.43) and it was higher than that in 10 years. Prevalence of gingival bleeding in good health group was -1.38 and it was lower than that in poor health group. Conclusions: The factors associated with gingival bleeding were age, subjective health, and tooth brushing frequency and time.

The Object of this study is as follows. we classify lumbago into ten kinds as mentioned in DongUiBoGam(東醫寶鑑), and are going to present each acupunture & moxibustion treatment. For the purpose of looking for each treatment, we referred to a large number of literature for lumbago treatment from ancient to modern. As a result of survey the references, we found out that lumbago due to kidney deficiency(腎虛腰痛) and lumbago due to cold-damp(寒濕腰痛) are more mentioned in many references than any other kinds, and that ten kinds of lumbago have each treatment. above all, In treatment of lumbago due to kidney deficiency(腎虛腰痛) bladder meridian, governor vessel meridian, kidney meridian and general points such as BL23, KI3, BL40, GV4, BL52 are used much in turn. also in treatment of lumbago due to cold-damp(寒濕腰痛) bladder meridian, governor vessel meridian, gallbladder meridian and general points such as BL23, BL40, GV3, GV4, SP9, GB30, Ah-Shi' points(阿是穴), BL25 are used much in turn. We conclude that ten kinds of lumbago have each different acupunture & moxibustion points and treatments, so if we follow each treatment we might obtain more higher rate of the treatment of lumbago.

Objectives : A safety issue on acupuncture and moxibustion treatment during pregnancy is as important as effectiveness. To establish a rationale and research strategy for future studies, a traditional literature review was performed to summarize how and for what conditions acupuncture and moxibustion treatment was given during pregnancy. Methods : An extensive traditional literature search for acupuncture and moxibustion treatment during pregnancy was conducted in texts on acupuncture and moxibustion, obstetrics and gynecology, and comprehensive medical texts. Treatment conditions, methods, and contraindications were summarized and tabulated. Results : Twenty-eight books were included in our review. Most frequent description of acupuncture and moxibustion treatment use during pregnancy was for difficult delivery including breech presentations; commonly used acupuncture points for difficult labor included LI4, SP6, BL67, BL60, KI6, ST30, SP12, LR4, LR3, PC6, CV3, CV14, KI13, and GB21, indicating that they may have to be avoided during pregnancy. Descriptions of other symptoms or conditions were sparse. For habitual abortion or recurrent miscarriage, moxibustion on GV4, BL23, CV3, KI8, and KI2 was indicated. A combination of LI4 and SP6, and CV4 were contraindicated during pregnancy consistently across the reviewed books. Conclusions : Our traditional literature review has shown that the use of acupuncture and moxibustion treatment during pregnancy has been limited. Given that more and more pregnant women are interested in safe and effective treatment, further research of acupuncture's safety and efficacy during pregnancy is urgently needed.

We have demonstrated an amplified wavelength-division multiplexed (WDM) passive optical network (PON) by using broadband light source (BLS) seeded optical sources and chirped fiber Bragg gratings (FBGs) based dispersion compensators. Chirped FBGs located at central office (CO) were fabricated and used as channel-by-channel dispersion compensators in order to mitigate the dispersion-induced distortion of both downstream and upstream signals. Owing to a low insertion loss of chirped FBG based dispersion compensator, the optical signal-to-noise ratio (OSNR) of the downstream signal could be improved to be ~28 dB. Thus, we re-confirmed that an error-free transmission of 1.25 Gb/s signals over a 100 km single-mode fiber (SMF) link could be achieved with a proposed amplified WDM-PON architecture. We have also evaluated the impact of various noises on the system's performance, and found that the low OSNR of the downstream signal would be a main limiting factor on the maximum reach of the proposed amplified WDM-PON architecture. From the measured ~13 dB improvement in OSNR of the downstream signal compared to our previously-proposed dispersion compensating module based scheme, we believe that the proposed architecture can accommodate a reach of longer than 100 km SMF link easily.
