Objectives: The objective of this study was to investigate the validity of the preliminary critical pathway of integrative medicine to improve the quality of life of lung cancer patients who received chemotherapy. Methods: The vertical axis of the preliminary critical pathway of integrated medicine consisted of nine domains: assessment, treatment, activity, consult, diet, medication, Korean medical examination, education, and others. The frame of the horizontal axis was the date from hospitalization to discharge. A total of 105 items in this preliminary critical pathway were validated by an expert group from October 28, 2016 to November 4, 2016. A total of ten experts from two different medical institutions participated in the validity test, using the four-point Content Validity Index (CVI) scale. The items with validity of greater than 80% were considered as significant. Results: The analysis of the content validity of 105 items showed 102 items with greater than 80% agreement. Assessment, treatment, consult, diet, medication, and education showed 100% agreement. Only three items showed a low validity (62.5%). Based on additional comments, the preliminary critical pathway of integrative medicine has been supplemented. Conclusions: This study suggests the possibility of using the integrated medical critical pathway for patients with lung cancer who received chemotherapy.

This research is focused on the development of GIS Diagnostic SYSTEM to prevent accidents beforehand by inspecting the internal defects of GIS (Gas Insulated Switchgear) which is a main power-facility for substations. GIS Diagnostic SYSTEM is categorized as 'Real time on-line test type' and 'Portable test type' depending on the types of testing, it uses PD(partial discharge) which mostly incurs in GIS internal defects, to inspect. As of now, mostly foreign equipments are imported for use due to the lack of the technology localization, and these are installed and operated on only some parts of highly-graded GIS power-facilities such as in 76skv or 345kv for its being expensive. Furthermore, other than foreign equipments being costly, it also has a weak point of very long unavailability in case of Diagnostic system break-down while using, because it takes a comparatively long period of corrective maintenance precesses. We have localized to develop personal real-time multi -functional GIS Diagnostic system which can test on all GIS power-facility comprehensively and economically therefore overcome all these problems mentioned above, a market expansion is expected from the decrease of price and replacing the import equipments in the future. As the equipment was developed to be Personal for the simple ways of installing and utilizing, it can be operated without any complex cable installation like other existing GIS Diagnostic system requires, therefore also decrease the cost of cable installation.

Objectives : To report and demonstrate the effect of decreasing ascites volume by SB intraperitoneal injection to a refractory ascites patient with synchronous colorectal liver metastasis and metachronous peritoneal carcinomatosis. Methods : Two cycles of intraperitoneal and intravenous SB injection were conducted. Each injection cycle was made up of 4 days. Nine vials of SB were injected to the patient every day. To compare the volume of ascites between pret- and post-treatment, follow-up computed tomography was done on June 3, 2013. To observe other therapeutic effects of SB injection, laboratory tests were conducted periodically. Results : On the follow-up computed tomography images, the amount of ascites and pleural effusion had decreased compared to the April 30, 2013 computed tomography images. The levels of aspartate transaminase, alanine aminotransferase and lactate dehydrogenase decreased significantly from May 9, to May 30, 2013. The amount of oral intake increased constantly during hospitalization. The patient's symptoms such as abdominal distension, abdominal pain and dyspnea were improving until discharge. Conclusions : Even if thiese results cannot be applied to every synchronous colorectal cancer liver metastasis patient, we demonstrated that SB intraperitoneal injection has ascites-decreasing effect to refractory ascites patients with synchronous colorectal liver metastasis and metachronous peritoneal carcinomatosis.

Phased isolation intrachannel clarifier ditch process developed in this study is an enhanced biological nutrient removal process employing two ditches with intrachannel clarifiers. Bench-scale phased isolation ditch process was used to evaluate the system performance on municipal wastewater and detailed assessment of internal behavior in a ditch and each reactions. When the system was operated at the HRTs of 6~12hours, SRTs of 9~31 days, and cycle times of 4hours, the system showed removals of BOD, TN, and TP as high as 88~97%, 73~78%, and 65~90%, respectively. The internal behavior were well matched on each reactions such as nitrification, denitrification, and phosphorus release and uptake. As the SRT became longer, TN removal increased gradually, whereas TP removal decreased contrarily. However, the system was capable of producing an effluent TP concentration 1mg/L or less even at longer SRTs except the case of solids discharge by malfunction of intra-clarifier occurred by its geometrical limit. The system performance slightly decreased by hydraulic shock loading(increasing of influent flowrate and decreasing of system HRT). However, the higher system performance could be achieved again after four cycles. Thus, the system reliability could be successfully achieved short-term hydraulic shock loading that occurred in medium- and small-sized wastewater treatment plants suffering fluctuation of influent quality and flowrate during wet season.

Background: Hemorrhoid surgery is a frequently performed surgery in Korea, second only to cataract surgery. However, it has serious complications, including bleeding, infection, anal stenosis, and urinary retention, so active conservative therapies are in need at an early stage. Case summary: Thirteen patients with anal disease complained of main symptoms of pain, bleeding, and prolapse, with additional complaints of itching and mucus discharge. An herbal medicine mixture of Eulja-tang and Hwangryeonhaedok-tang was administered twice daily, and dry cupping therapy, acupuncture, and hot pack placements were administered on pelvic and sacral regions once weekly for four weeks. The symptoms were evaluated before and each week after the treatments. The treatments had statistically significant therapeutic effects. Conclusion: Korean medicine treatment-effectively alleviating the symptoms of anal disease, such as pain, bleeding, and prolapse-may represent an alternative therapy for conservative treatments in the early stages of anal disease.

This work reports the case of a middle cerebral artery infarction patient with hyperhidrosis and left upper extremity paresthesia whose condition improved following Korean medicine treatment. The patient was hospitalized for 10 days and treated with herbal medicine, mainly Hwanggigyeji-tang, and acupuncture, electroacupuncture, and moxibustion. The hyperhidrosis was clinically classified and the patient's subjective discomfort in this regard was also checked. A subjective percentage of strength and sensation in the left extremity was evaluated to assess the clinical effects of the treatment. After treatment, the hyperhidrosis classification improved from Grade 3 to Grade 0, and the patient's subjective discomfort was greatly improved and continued for the two weeks after discharge. In addition, subjective strength and sensation improved by 20% and 5%, respectively, compared to time of admission. These results suggest that Korean medicine is effective in treating paresthesia after stroke and long-lasting hyperhidrosis.
