Objective : Lumbar disc herniation (LDH) is a common disease, and lumbar discectomy (LD) is a common neurosurgical procedure. However, there is little previous data on return to work (RTW) after LD. This study investigated the period until the RTW after LD prospectively. Clinically, the pain state at the time of RTW also checked. RTW failure rate 6 months after surgery also investigated. Methods : Patients with daily/regular jobs undergoing LD between September 2014 and December 2018 were enrolled. Pain was assessed by the Oswestri Disability Index (ODI) and the Numeric Rate Scale (NRS). Employment type was divided into self-employed, regular and contracted. Monthly telephone interviews were conducted to check RTW status and self-estimated work capability after surgery. Results : Sixty-seven patients enrolled in this study. Three patients failed to RTW, and three others resigned within 6 months after surgery. The preoperative NRS and ODI were 7.2±1.2 and 22.1±7.9, respectively. The average time to RTW was 5.1±6.0 weeks. At RTW, NRS was 1.5±1.8 and ODI was 6.3±3.9. Amongst patients that successfully returned to work were 16 self-employed workers, 42 regular employees, and three contracted workers. The time to RTW of self-employed, regular, and contracted workers were 5.9±8.8, 4.2±4.3 and 13.3±2.3 weeks, respectively (p=0.011). Thirty-six of the patients that returned to work self-reported a 22.8±15.6% reduction in work capability at 6 months. Conclusion : RTW may vary depending on the employment status. In this study, we found that while employment type may affect the length to RTW, most patients were able to RTW and >40% of patients reported no loss of work capabilities 6 months postoperatively, hopefully alleviating some patient hesitation towards LD.

To produce functional food ingredient from the soybean curd residue (SCR), alkaline fermentation was performed with SCR from cold processed (D-SCR) or hot processed (P-SCR) tofu. The solid- state fermentation was performed by Bacillus firmus NA-1 at $42^{\circ}C$. The fermentation of heat-treated D- SCR resulted in higher production of peptides and fibrinolytic enzyme compared with D-SCR without heating. The P-SCR showed higher production of peptides, fibrinolytic enzyme, indicating alkaline pH after fermentation for 18 hr. When the moisture content of P-SCR was reduced to $60\%$, the production of peptides and fibrinolytic enzyme were enhanced. The P-SCR fortified with $10\%$ MFS (micronized full-fat soy flour) showed higher fibrinolytic enzyme activity and consistency index by fermentation of Bacillus firmus NA-1 Furthermore, the P- SCR fortified with $20\%$ MFS indicated relatively higher peptide content, fibrinolytic enzyme activity and enhanced flavor. By increasing the addition of MFS, the peptide content of fermented P-SCR was increased significantly, but fibrinolytic enzyme was slightly decreased.

Malnutrition is a common problem in cancer patients. In addition anticancer drugs used in chemotherapy as a major therapeutic mode are famous as the side effect like nausea, vomiting, which lead the patients to malnourished state. This study was to determine the relationship of anorexia, nausea, vomiting and oral intake and identify the influence these side effects on the nutritional status in patients receiving chemotherapy. To assess the nutritional status, anthropometry such as weight, height, body mass index(BMI), body fat proportion, and triceps skinfold thickness, and biochemistry test such as hemoglobin and lymphocyte were measured at the pre- and post- chemotherapy and the readmission time, all three times. During chemotherapy, anorexia, nausea, and vomiting using a VAS or 5-point scale and 24 hour oral intake using a food record were measured daily. Forty-nine patients knowing their diagnosis and receiving chemotherapy were recruited from an oncological ward in a general hospital for 5 months and they were reduced 31 at readmission time for a next chemotherapy. The results were as follows. Most subjects (93.6%) were in the 4th stage of cancer and 57.1% of subjects were in the first or the second chemotherapy. In most subjects(82.6%), their weight was decreased 10.7% than as usual. The degree of anorexia, nausea, and vomiting was significantly higher and the amount of oral intake was significantly less during the chemotherapy than at the pre-chemotherapy. Weight, BMI, triceps skinfold were reduced more at the post- chemotherapy than the pre-chemotherapy and were recovered the nearly same but less level at the readmission time. Body fat proportion was increased at the post chemotherapy and then decreased at the readmission phase. Hemoglobin and the number of lymphocyte were below normal at the pre-chemotherapy and more reduced at the readmission time. Anorexia, nausea, and vomiting were related positively and oral intake was negatively related with nausea and vomiting. The nutritional status at the post- chemotherapy and the readmission time was explained 20% over by the side effect like anorexia, nausea, vomiting and oral intake during the chemotherapy. The significant nutrition predictors at the post- chemotherapy were vomiting and the significant predictors at the readmission time were anorexia, vomiting, and oral intake. These results indicated the patients receiving chemotherapy were continued to deteriorate the nutritional status. Therefore nurse should have knowledge how much the nutritional status can be affected and assess the nutritional status periodically and try to find out the intervention for side effects from the series of chemotherapies.

Objectives The aims of this study was to observe the effectiveness of East-West Integrative Medicine (EWIM) by analysing between EWIM estimated group and Non-EWIM eastimated group with Brain Rehabilitation Registry. Methods We divided hospitals into two groups, one is EWIM estimated group hospital (Kyeonghee university, Wonkwang university, Dongguk university) and the other is non-EWIM estimated group (Jeonnam university, Gyeongbuk university, Catholic university). Then we analysed the effectiveness of treatments retrospectively using the database of Brain Rehabilitation Registry (http://www.kbrr.or.kr/, version 1.0). Totally 293 patients were included, EWIM estimated group was 175 and non-EWIM estimated group was 118. The main outcome measurements were National Institutes of Health Stroke Scale (NIHSS), Modified Barthel Index (MBI) and Mini Mental State Examination-Korea (MMSE-K). Results Changes of NIHSS was not significant in both total patient and patient who treated over 3 weeks. MMSE-K showed positively significant difference (p=0.044) in EWIM estimated group patients who treated over 3 weeks. In case of MBI, EWIM estimated group showed more effective result and also statistically significant in both total patients and patients who treated over 3 weeks. Conclusions We patially argued that EWIM estimated group was more effective than non-EWIM estimated group in stroke patients' functional recovery. We suggested base data of EWIM in stroke patiens through this study and this could be applied future researches of developing modified EWIM system.

The diagnostic requirements were suggested and explained regarding the systems of differentiation of syptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows : -differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to reletive excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) -differentiation of diseases according to pathological changes of the viscera and their interrelation(臟腑辨證) -analysing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following odor : another name(異名), notion of diagnosis parrern(證候槪念), index of differentiation of syptoms and sings(辨證指標), the main point of diagnosis(診斷要點), analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a wayof curing a diseases(治法), prescription(處方) , herbs in common use(常用藥物), dieases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

Objectives: Electroacupuncture according to Voll (EAV) has been used to quantify the skin's electrical resistance and conductance over acupuncture points that, based on traditional Chinese medicine, represent the state of health or disease of the organ or tissue. However, it doesn't have enough objective data yet, so the purpose of this study was to aid in the use of EAV in analysis of cerebrovascular disease risk factors. Methods: This study researched the clinical statistics of 216 cases: cerebrovascular attack (CVA) group 43, control group 173. We measured control meridian points (CMP) on hands and feet and the cardio ankle vascular index (CAVI) which represents atherosclerosis severity, and sex, age, hypertension, diabetes, dyslipidemia, and obesity. The data were then analyzed by t-test, chi-square test and logistic regression. Results: Between the CVA and control groups, there were not statistically significant differences in CMP. However, logistic regression analysis of the presence of CVA, mean of CMP heart and lung, sex, age, DBP (diastolic blood pressure), and HDL (high density lipoprotein) cholesterol showed that the risk of CVA was 1.1 times increased with CMP heart (p=0.002), in men was 4.12 times higher than in women (p=0.001), 1.09 times higher with age (p=0.000), 1.04 times higher with DBP (p=0.045), while was lower by 0.924 times with CMP lung (p=0.005) and 0.957 times with HDL cholesterol (p=0.006). Conclusion: Although there were not clear evidence or mechanisms about EAV, this study showed that if we study EAV further, we may be able to apply EAV as an objective instrument of oriental medicine in cerebrovascular disease.

Purpose: The vein graft was considered as a useful conduit for nerve defect. But the problem is that it might be collapsed in long vein graft state. A new experimental model using vein graft filled with hyaluronic acid was considered. Methods: Thirty rats were used for the experimental animal. In group I, one side of the femoral nerve was exposed and a segment was removed about 15mm. The neural gap was connected with nerve graft. In group II, the nerve gap was connected with vein graft only. In group III, the nerve gap was connected with vein graft filled with hyaluronic acid. A walking track analysis was made periodically for 2 months and NCV(nerve conduction velocity) was executed at the end of the experiment. And morphologic studies were also done for all groups Results: In a walking track analysis, the toe-spread was widen and the foot-length was lengthened. The recovery of the toe-spread and foot length was checked 2 weeks interval, periodically for two months. The SFI (sciatic function index) was $-52.5{\pm}8.2$ in group I, $-68.1{\pm}4$ in group II, $-55.3{\pm}7.9$ in group III. In electrophysiological study, NCV(nerve conduction velocity) was $26.71{\pm}3.11m/s$ in group I, $17.94{\pm}4.35m/s$ in group II, $25.69{\pm}2.81m/s$ in group III. The functional recovery in group I and III was superior to that the group II statistically(p < 0.05) Under electromicroscopic study, the number of the myelinated axons were $1419.1{\pm}240$ in group I, $921.7{\pm}176.8$ in group II, $1322.2{\pm}318$ in group III. The number of the myelinated axons were much more in group I and III than group II statistically (p<0.05). Conclusion: This study suggested that the vein graft filled with hyaluronic acid is more effective than vein graft only for the conduit of the nerve gap. It was thought that the technique could be used in clinical cases with nerve defects as an alternative method to classical nerve grafts.

Concrete pavement of Jungbu Expressway composed of CRCP(Continuously Reinforced Concrete Pavement) and JCP(Jointed Concrete Pavement). The CRCP was firstly constructed and applied to new expressway in Korea. It is a good source of the study to analyze the performance of CRCP and JCP because it experiences same amount of traffic and environmental loading. Up to the present, condition survey has conducted several times during 13 years but roughness measurement has not been carefully conducted. Through comparisons among several types of pavement(CRCP, JCP, Asphalt) by roughness, CRCP is superior to JCP. In addition, connected sections in the highway such as bridges and tunnels that have higher IRI values, about 5mm/m, than normal sections should be considered appropriated maintenance such as diamond grinding. The relationship between IRI and distresses carried out by Korea Highway Cooperation in 1999 skewed that the number of crack is related to IRI value in JCP, while other distresses of JCP and CRCP are not shown clearly. The comparison study with IRI values between Jungbu Expressway and GPS-3(JCP) and GPS-5(CRCP) of LTPP data also showed that roughness of Jungbu Expressway is not inferior to that of the state. Some of section showed larger values of IRI are linked with under-9round structures for passages and drainages. The overall performance considering only roughness, the CRCP is also superior to JCP in sections with under-ground tunnels.

Purpose: To describe the effectiveness of traditional Korean medicine (TKM) on the patients with secondary dementia (case 1: Rt. MCA infarction; case 2: traumatic subacute subdural hemorrhage and traumatic intracranial hemorrhage; case 3: delayed encephalopathy after carbon monoxide poisoning). Methods: We used a complete TKM treatment. The acupoints used were as follows: acupoints frequently used in hemiparesis (GV20, GV24, ST4, LI11, LI14, ST36, GB34, SP9, and LR3), and we used herbal medicine (補腎益腦湯加味, Boshiniknoe-tang-gami). The efficacy was evaluated using the Mini-Mental State Examination for Dementia Screening (MMSE-DS) and the Modified Barthel Index (MBI). Results: After treatment, the total MMSE-DS score was increased from 14 to 24 (case 1), 14 to 19 (case 2), and 0 to 17 (case 3). The total K-MBI was increased from 30 to 44 (case 1), 82 to 86 (case 2), and 30 to 86 (case 3) Conclusions: We suggest that TKM could positively influence cognition and improve activity of daily living (ADL). This study has limitations, so further studies are needed.

This study investigated the effects of Origanum majorana essential aroma therapy on electrical activity in the brain as evaluated by an electroencephalogram (EEG). The subjects were 29 healthy female young adults, and their sleep quality was assessed by using the Pittsburgh Sleep Quality Index. EEG electrodes were attached at the frontal, temporal, occipital, and parietal lobes according to the international 10-20 system. Subjects were exposed to organic Origanum majorana essential aroma (50 ${\mu}l$) for a period of 3 minutes each before, during, and after aromatherapy. Subjects with good sleep quality showed that Origanum majorana essential aroma increased the theta power at the frontal and temporal lobes of both cerebral hemispheres, the left parietal lobe, and the right occipital lobe. Furthermore, Origanum majorana essential aroma decreased the alpha power at the left occipital lobe and the beta power at the right temporal lobe. On the other hand, subjects with poor sleep quality showed an increase in the theta power at the temporal lobe of both cerebral hemispheres and a decrease in the alpha power at the left parietal lobe by Origanum majorana essential aroma therapy. It is concluded that Origanum majorana essential aroma therapy diminishes the state of wakefulness in the brain; alpha and beta powers were both decreased in the subjects with good sleep quality, but only alpha power was decreased in the subjects with poor sleep quality. Moreover, Origanum majorana essential aroma therapy has a sleep-inducing effect in both subjects with good sleep quality and poor sleep quality.
