This study compared and analyzed manual tapping and automatic tapping regarding tapping process characteristics of titanium hard-to-cut-material. Tapping process characteristics of titanium hard-to-cut-material are evaluated as the quality of a screw, wear of a tap, economic analysis, and cycle time etc. The type of screw threads after manual tapping is formed as an irregular type of screw threads, and perfect screw threads are created after automatic tapping. In addition, the chip type after manual tapping process is formed as the discontinuous chip due to work hardening, and the powder type of chip after automatic tapping process is created. In terms of cycle time, an automatic tapping process is shortened by 70% compared to manual tapping process. Insert tip wear of an automatic tapping shown in the process of 5-hole tapping is not found, but hand tap wear for finish cutting is most severe.

Objectives To evaluate the evidence supporting the effectiveness of Chuna manual therapy for nocturnal crying. Methods We conducted search across the 3 electronic databases (Pubmed, CAJ and Oasis) to find all of randomized controlled clinical trials(RCTs) that used Chuna manual therapy as a treatment for nocturnal crying. The methodological quality of each RCTs was assessed using the Cochrane Risk of Bias tool and nRCTs was assessed using the Cochrane Risk of Bias Assessment tool for Non-randomized Study tool. Results Two RCTs and three nRCTs met our inclusion criteria. The meta-analysis showed positive results for the use of Chuna manual therapy in terms of the efficacy rate when compared to medication treatments alone. Positive results were also obtained, in terms of the efficacy rate, when comparing Chuna manual therapy combined with acupoint application therapy to Chuna manual therapy alone, but was not statistically significant. Conclusions Our systematic review found encouraging but limited evidence of Chuna manual therapy for nocturnal crying. We recommend clinical trials which compare the effectiveness of Chuna manual therapy with usual care to obtain stronger evidence without the demerits of trial design.

Objectives : To evaluate the effectiveness of Chuna Manual Therapy for adhesive capsulitis by a systematic review manner. Methods : Five foreign electronic databases (Pubmed, Ovid-medline, Embase, Cochrane library, Chinese Academic Journals (CAJ)) and two Korean medical electronic databases (Oriental Medicine Advanced Searching Integrated System (OASIS) and Research Information Sharing Service (RISS)) were searched to find all randomized controlled trials (RCTs) using Chuna Manual Therapy as a treatment for adhesive capsulitis. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results : Twenty-one RCTs met our inclusion criteria. The meta-analysis showed positive results on the use of Chuna Manual Therapy combined with acupuncture or exercise therapy in terms of the efficacy rate and pain using the Visual Analogue Scale (VAS), compared to acupuncture or exercise alone [SMD-1.81 (95% CI & -2.54, -1.08), P<0.001, RR 1.19 (95% CI 1.14, 1.23), P<0.001)]. Positive results in terms of efficacy rate were also obtained comparing Chuna Manual Therapy to acupuncture alone [RR 1.10 (95% CI 1.02, 1.18), P=0.01]. Conclusions : Our systematic review found favorable results on the effectiveness of Chuna Manual Therapy for pain and efficacy rate of adhesive capsulitis. However, evidence was limited due to the lack of well-designed RCTs. More qualified clinical trials are needed to obtain stronger evidence.

Background: Cervical radiculopathy is the result of cervical nerve root pathology that may lead to chronic pain and disability. Although manual therapy interventions including cervical traction and neural mobilization have been advocated to decrease pain and disability caused by cervical radiculopathy, their analgesic effect has been questioned due to the low quality of research evidence. The purpose of this paper is to present the effect of manual therapy on pain, ROM, disability in a patient experiencing cervical radiculopathy. Methods: In this study, 30 participants who met the diagnostic criteria for cervical radiculopathy were randomized into two groups: group I (nerve mobilization group) & group II (Mckenzie exercise group). The experimental group was performed manual cervical traction and neural mobilization technique. The control group was performed manual cervical traction and cervical retraction, extension exercise. Assessments were performed to 30 participants before and after 4 weeks therapy. The components of assessments were pain intensity (PI), cervical rotation ROM (CR) and neck disability index (NDI). Results: After 4 weeks therapy, PI, CR and NDI were significantly reduced in both groups (p<.01). The PI, CR and NDI were no significantly reduced between group I and group II (p>.01). Conclusions: Manual therapy could reduce the symptoms of cervical radiculotpathy.

In general, manual calibration is commonly used for the stream water quality modelling. Because the manual calibration depends upon the subjectivity and experience of the researcher, it has a problem with the objectivity of the modelling. Thus, the interest about the automatic calibration by the optimization technique is deeply increased. In this study, Influence coefficient algorithm and Genetic algorithm are introduced to develop an automatic calibration model for the QUAL2K that are the latest version of the QUAL2E. Genetic algorithm, used in this study, is very simple and easy to understand but also applicable to any complicated mathematical problem, and it can find out the global optimum solution effectively. The developed automatic calibration model is applied to the Gangneung Namdaecheon. The calibration results about the 11 water quality variables show the good correspondence between the calculated and observed water quality values.

Recently, drinking water quality has significantly improved with the progress of water treatment technologies, however, customer's trust on tap water is still relatively low. Low trust on water quality is mainly due to vague anxiety. Therefore, to improve customer's trust on drinking water quality new strategy such as water safety plan(WSP) which recommended by WHO and IWA should be introduced. WSP can be defined as an approach which uses comprehensive risk assessment and risk management approach that encompasses all steps in water supply from catchment to consumer to ensure the safety of a drinking water supply. In this study, cases on WSP introduction in other countries as well as strategy for the introduction of WSP in Korea were investigated. In addition, recommendations on the improvement of the current water contamination response manual was suggested based on the analysis of the existing manual at a full scale water treatment plant.

This study was aimed at comparing and assessing SPT-N values both measured by automatic and manual record devices of Standard Penetration Test. As a result, energy efficiency of hammer was approximately 62.9%, meaning SPT-N value measured by automatic recording device showed relatively accurate performance that the one done by manual device. Given the relations between hit frequency of automatic recording device and intrusion, the characteristics of stratum are expected to be proved in more accurate way. Additionally, higher confidence level seems to make it preferred and quality assessment method.
