  • This research aimed at to develop a quantitative assesment technique which uses the measured displacements at the excavated plane during tunnel construction. Tunnel structure has a feature with long extents comparing to the excavated section so that the tunnel safety assesment is more effective by using the measured data of displacements. Tunnel structures show different structural behaviors due to the mechanical characteristics of ground and supports themselves, excavation methods and construction methods of supports, etc. From this point of view, it has very important meanings on the practical aspects that the measured data from the construction cite represent the features of the interaction effects between ground and supports as they are. In this study, both the stress state and the properties of surrounding ground are analyzed by newly incorporated feedback analysis technique which can use the measured displacements directly. Then, the stress state and the properties of ground will be used to obtain the strain distribution of surrounding ground. Finally the tunnel safety can be assessed by comparing the estimated strain through the analysis to the allowable strain of ground quantitatively.

  • Diagnosis and treatment procedures in cancers and resulting anxiety negatively affect the individual and the family. Particularly treatment methods may generate psychological symptoms. The aim of this study was to determine the level of such symptoms in Turkish gynecologic cancer patients receiving chemotherapy. A total of 41 patients who were referred to our gynecologic oncology research clinic between January-March 2012, receiving 3 months or more chemotherapy and who agreed to participate were enrolled in study. All the data were collected using a personal information form, Edmonton Symptom Assesment System and State-Trait Anxiety Inventory. Patients received highest point average from fatigue symptom ($6.53{\pm}2.67$) and lowest point average from dyspnea ($1.53{\pm}3.03$) according to Edmonton Symptom Assesment System. The mean State Anxiety score of patients was $43.1{\pm}9.77$ and mean Trait Anxiety score was $46.7{\pm}7.01$. Comparing symptoms of patients and mean State Anxiety score it was found that there was a statistically significant corelation with symptoms like pain (p<0.05), sadness (p<0.001), insomnia (p<0.05), state of well being (p<0.001) and dyspnea (p<0.05). Similarly comparing symptoms of patients and mean Trait Anxiety score demonstrated significant correlations for fatigue (p<0.05), sadness (p<0.01), insomnia (p<0.01) and state of well-being (p<0.01). As a result, patients with gynecological cancers experienced symptoms related to chemotherapy and a moderate level of anxiety. In accordance, appropriate interventions should recommended for the evaluation and improvement of anxiety and symptoms related to treatment in cancer patients.

  • This study is intended to analyze the characteristics of the preference according to the locations of view points, which are the current criteria for the evaluation of the view. To this end, a total of fifty one test cases according to view point locations were sampled based on the picture data collected in previous studies, and preference assessment was conducted on these cases to identify preference characteristics, where a five-point Lickert-scale evaluation was performed for each test case, and three test cases for each type were comparatively evaluated. It is deemed that the findings from this study may be used to finally derive qualitative assesment scale for the view seen from apartment units.

  • Objectives : Scalenus anticus syndrome and Piriformis syndrome is representative of myogenic Nerve entrapment syndrome, and their clinical symptoms are similar to HIVD(herniated Intervertebral disc) of cervical or lumbar spine. But, distinguished by muscle test, these syndrome apply to Meridian-muscle therapy. Methods : Meridian-muscle therapy consists of Ashi(阿是)-point therapy, taping therapy, myofascial release technique, manipulation, their based on the traditional meridian-muscle theory. This theory is similar to myofascial pain syndrome in western medicine. The study population consisted of 9 patients who were already diagnosed as Nerve entrapment syndrome with radiological examination & physical examination and muscle test. The evaluation of clinical outcome was done by Visual Analogue Scale (VAS) and Pain Assesment Questionnaire(PAQ). Results and Conclusions : After treatment, All patient's VAS is decreased as $2.11{\pm}1.59$ and the evaluation of clinical effect was excellent(6 cases) or good(3 cases) according to PAQ. Conclusively, Meridian muscle therapy is efficacious against Nerve entrapment syndrome.

  • Turnout system is a mechanical installation enabling trains to be guided from one track to another which is consists of point blades, common crossing and guard rail etc. These structural feature causes vibration, noise and damages while railroad car wheel is passes by. A tilting train is a train with a tilting mechanism that enables increased speed on regular railroad tracks. The aim of this paper is to study a characteristics of the shock-vibration and noise of tilting and existing train passes by turnout systems. To analyze and assesment, noise and vibration measurement was carried out at the Naesu-station of Chungbuk-line which equipped with cast manganese crossing and built-up crossing and Illo-station of Honam-line which equipped with cast manganese crossing.

  • This paper presents a calculation method of the area of severity for the stochastic assessment of voltage sags. In general, the annual expected numbers of voltage sags at an individual load point can be estimated stochastically. However, in order to assess the system voltage sag performance considering many sensitive load points together, it is necessary to determine and analysis the area of severity for the load points. The area of severity to voltage sags is the network region where the fault occurrences will simultaneously lead to voltage sags at different load points. In this paper, the concept of the voltage sag assessment and the calculation method of the area of severity are addressed. The analysis of the area of severity is performed on the IEEE 30-bus test system by using the proposed method. The method is useful for the stochastic assesment of voltage sags and the establishment of systematic plans for voltage sag mitigation.

  • This paper presents a method to apply energy margin for assesment of total transfer capability (TTC). In order to calculate energy margin, two values of the transient energy function have to be computed. The first value is transient energy that is the sum of kinetic and potential energy at the end of fault. The second is critical energy that is potential energy at controlling UEP(Unstable Equilibrium Point). It is seen that TTC level is determined by not only bus voltage magnitudes and line thermal limits but also transient stability. TTC assessment is compared by the repeated power flow(RPF) method and optimization method.

  • The Track geometry measuring on High-speed railway is the most important subject for the track construction and track maintenance work. Also the measuring accuracy is so significant part because it provides principle data for the maintenance plan and the assesment of working quality and can control the train speed limitation. From this point of view, it is very important to verify for the track recording coach(EM120) in KNR. According to the result of spectrum analysis, the noise near 1m waveband was found on the track recording data from EM120. So, New filter has been applied to remove the noise form track recording data. and it makes possible to acquire resembling result to real track geometry.
