Objectives: The aim of this paper was to aid Korean clinical practices for determining clinical and subclinical hypothyroidism and to identify further relevant studies by summarizing the present domestic clinical studies. Methods: The research consisted of a review of articles up to July, 2018 found by searching 'Hypothyroidism' and 'Hashimoto's thyroiditis' as keywords in five domestic electronic databases. Results: Only nine studies satisfied the selection criteria and were analyzed. These included six case reports, two controlled clinical trials, and one randomized controlled trial. Of these, Anjeonleejoong-tang was the most frequent herbal medicine used to treat hypothyroidism. Conclusions: Systematic and large-scale research studies are needed to standardize the guidelines for traditional Korean treatment of hypothyroidism.

In this paper, we have taken the formation of two-dimension codeword named doubly-encoded code using the Reed-Solomon code, C1(32, 28) with minimum distance 5 and C2(32, 26) with minimum distance 7 and we have had computer simulation of these error correcting processes using modeled R-DAT (Rotationary Digital Audio Tape). As the result, the error rate per symbol has been decreased about 0.05 and on these processes, the newly developed digital signal processing technology such as erro correction using Berlekamp-Massey algorithm in frequency domain have been proven.

Life prediction and residual life prediction of structures of machines are one of the most strongly world wide needed problems as requirement in the stage of slowly developing economy which comes after rapidly and highly developing stage. For the purpose of statistical life prediction, fatigue test was conducted under the 4 stress levels, and for each stress level, about 20 specimens are used. The statistical properties of crack growth parameter m and C in the fatigue crack growth law of da/dN=C(.DELTA.K)sup m/, and the relationship between m and C, and the statistical distribution pattern of fatigue crack growth rate can be obtained by experimental results.

Objectives: This study evaluates the effect of Korean medicine in a patient with multiple system atrophy-C (MSA-C). Methods: A patient diagnosed with MSA-C was treated with herbal medicine (Boyangwhano-tang hap Yeokgan-san), acupuncture, and moxibustion for 8 weeks. Clinical improvements were evaluated by the unified MSA rating scale (UMSARS) and the scale for the assessment and rating of ataxia (SARA). Results: Improvements in the total scores of UMSARS Part I, II, and IV and SARA were observed after Korean medicine treatments. However, there were no improvements to the urinary and autonomic dysfunctions. Conclusions: Korean medicine treatment may be an effective treatment for a degenerative, progressive disease like MSA-C.

As the number of websites managed by organizations or organizations increases, so does the number of web application servers and containers. In checking the status of the web service of the web application server and the container, it is very difficult for the person to check the status of the web service after accessing the physical server at the remote site through the terminal or using other accessible software It. Previous research on crawler-related research is hard to find any reference to the processing of data from crawling. Data loss occurs when the crawler accesses the database and stores the data. In this paper, we propose a method to store the inspection data according to crawl - based web application server management without losing data.

Objective: This study evaluates the effect of Korean medicine in a patient who suffered from unspecified arthritis with fever of unknown origin. Methods: A patient was treated with herbal medicine for 12 weeks. The clinical improvements were evaluated by body temperature, blood test (CBC-diffcount, CRP, ESR, etc.) and Visual Analogue Scale (VAS). Results: Improvements in body temperature, blood tests and clinical symptoms were observed after Korean medicine treatments. Conclusions: Korean medicine treatment may be an effective treatment for unspecified arthritis with fever of unknown origin.

The purpose of this study is to report the clinical effect of Korean medicine on a patient who experienced headaches and nausea after post-concussion syndrome. The patient was treated with herbal medicine (Oryung-san, Hwangryunhaedok-tang-tablet) and acupuncture for four weeks. As a result, the pain degree compared to the day of hospitalization of headache and nausea and pain rating score of headache decreased after treatment. Therefore, this case is useful for describing Korean medicine treatment for headache and nausea after post-concussion syndrome, and further case reports and studies will be needed in the future.

The safety of gas utilities is intimidated by many causes. Among them, subsidence is a dominant cause to decrease the safety of gas utilities. So it is very important to monitor the displacement of subsidence. The purpose of this study is to on-line monitor the subsidence of gas utilities using Static GPS(Global Positioning System)technique. Static GPS technique, which is one of various GPS techniques and originally applied to monitor the crustal activity, was applied for two gas station in Korea Gas Corporation. Prior to applying this technique to the field, i.e, gas station, a preliminary test was peformed to confirm the accuracy of this technique. As a result, it was proved that this technique can measure the displacement of gas utilities three dimensionally by sub-millimeter. After getting confirmation of GPS technique, we applied this technique for two gas stations and monitored the amount of subsidence during 5 months. As a result of field test, we can conclude that the gas stations was subsiding several millimeters in a year.

Cell zooming adjusts the cell range of base stations depending on traffic condition. The cell zooming can be implemented by the adjustment of antenna angles, the clustering of the base stations, and the cell relay. The base stations can adjust the cell range in term of energy efficiency, which can then reduce the overall energy consumption of cellular networks. There is, however, a trade-off between the energy savings and the blocking probability of user calls. A periodic scheme that manages the cell zooming of the base stations was proposed but it was inadequate for dealing with the dynamic nature of traffic patterns. This paper proposes a semi-periodic cell zooming scheme along with the algorithms that select such base stations and define the operation procedure. Simulation results show that the proposed method outperforms the existing scheme in terms of the energy savings without the degradation of the blocking probability.
