This paper aims to investigate ideological preferences of news media outlets by looking at the news coverage of North Korea-Russia summit in April, 2019. The meeting has gained attention in South Korea, China, Japan and America in that the historical meeting will reflect the future direction for denuclearization on the Korean peninsular and the peace in the world. Given this, in particular, a special attention is paid to the editorials and headlines of news articles reported in two Korean quality newspapers, DongA Ilbo and Hankyoreh because both are quality newspapers, but are ideologically different. To achieve objectivity and fairness, the same issues dealt with during the summit were compared and analyzed within Martin and White (2005)'s Appraisal framework. As a result, it was found that in editorials of DongA Ilbo showed a negative stance to the summit by employing the 'attitude' factor, whereas the Hankyoreh was overwhelmingly positive toward the issue, also by employing the 'attitude' factor. The political stance is likely to be in line with those shown in the headlines of news articles from each newspaper. That is, it is clear that each news outlet shows its ideological stances to news consumers through linguistic expressions, in that both editorials and the headlines of news articles express their political preferences to the summit by means of linguistic appraisals.

Purpose: Campylobacter species are common causes of bacterial enteritis. There is limited knowledge on its prevalence and clinical features because of its fastidious culture conditions. The purpose of this study was to identify the clinical features of Campylobacter enteritis in children. Methods: We obtained stool specimens from patients diagnosed with acute gastroenteritis in the Department of Pediatrics, Nowon Eulji Medical Center (NEMC) and identified the pathogens by performing cultures or polymerase chain reactions (PCR). We retrospectively reviewed the medical records of patients with Campylobacter enteritis at NEMC between January 2012 and December 2017. Results: Overall, 123 patients were diagnosed with Campylobacter enteritis (60 by culture and PCR in EnterNet and 110 by multiplex PCR). The median (interquartile range [IQR]) age of patients was 12 years (IQR, 8 to 16 years). The disease occurred all year round, but 69.9% from June to September. Symptoms included diarrhea (97.6%), fever (96.7%), abdominal pain (94.3%), vomiting (37.4%), and headache (34.1%). Compared with other treatments, treatment with azithromycin was associated with a shorter hospitalization period (P<0.05). Conclusions: Campylobacter enteritis is common during summer and mostly infects adolescent patients. It causes severe abdominal pain and fever preceding the onset of diarrhea. Prompt diagnosis and appropriate use of antibiotics reduces the duration of the disease.

In Post-soviet Space, particularly the Central Asian is a great turbulence region called the 'Eurasian Balkan', where diverse factors of conflict and dispute are existed. In Central Asia, a current regional security system is characterized by various multilateral cooperation relations among Central Asian nations and the world powers, such as NATO(PfP), OSCE, CIS, CSTO, CACO, SCO, CICA and so on. But nothing could obtain superiority as pan-regional security system. Unless internal problems and conflicts of the Central Asian nations be solved, security won't be assured in this region. Narrow-minded and blind realism will spread insecure region, make a lasting trouble spot in Eurasian continent. The purpose of this article is to explore significance for international relations of security system in the Central Asia. I examine general features of regional security environment formed after the Soviet Union's collapse, characteristics of multilateral cooperation related with Central Asian nations. Through consideration current situations I suggest prospects of security system in Central Asia.

한국은 백 년 이래로 군사적 침략과 경제적 대변혁을 맞았으며, 또한 종교와 문화적 측면에서 전통의 중흥기와 서학의 유입에 대한 문제를 경험하게 되었다. 이런 점에서 한국의 역사적 경험은 주변 국가의 국민들이 배울 만한 의미가 있다고 생각된다. 이와 연관하여 대순진리회가 역사를 계승하고 창신을 이루어나가는 측면의 문제는 정리해볼 만한 가치가 있다. 대순진리회의 종지는 '음양합덕, 신인조화, 해원상생, 도통진경'이다. 특히 대순진리회는 해원상생 사상으로 조화정신을 집중적으로 잘 나타내고 있다. 대순진리회의 해원은 고대 단주로부터의 원을 푸는 것에서 시작되며, 인류가 근본적으로 여러 세대에 걸친 원한을 풀어야만 행복하고 안락한 시대에 진입할 수 있다는 역사관을 보여주고 있다. 대순진리회가 해원을 푸는 방책으로 제시하는 상생은 당시의 갑오동학혁명이나 역사상 많은 종교에서 원한을 해결하는 방법과 구별되는 것이다. 과거에 있어서는 상극의 방법으로 원한을 해결하여 왔으나, 상극의 방식은 오히려 새로운 원한을 더욱 만들어 낼 수 있기 때문에, 현대에 있어 원한을 제거할 수 있는 방법은 악을 선으로써 대하는 것이라고 한다. 증산 성사 및 그 후학들은 사회의 질서를 새롭게 세우는 문제와 전통사회에서 인간 간의 조화를 방해하고 원한을 용인하는 구습을 개조하고 원을 소멸하는 문제에 주의를 기울였다. 이러한 변혁은 평등의 관념을 나타내고 있다. 증산께서는 전 세계적인 관점에서 민족과 국가 그리고 종교 간의 조화를 실현해야 할 것을 강조하셨다. 당시 동아시아 국가는 매우 폐쇄적인 상황에서 서양 국가의 침략을 받던 시기였는데, 증산 성사께서 미래의 세계는 마땅히 화합을 이루고 서로의 장점을 배우는 세계가 될 것임을 예견하셨다는 것은 그의 위대함을 보여주는 대목이다. 증산의 후천개벽사상 역시 조화의 정신을 나타내고 있다. 후천개벽사상은 전통적 참위를 현대적으로 개조한 것으로 민중을 적극적으로 인도하기 위한 것이다. 다음으로, 증산께서는 각 종교에 대해 관용적인 태도를 표하셨고, 또한 매우 진지한 태도로 타 종교로부터 자신이 주창하는 사상과 관련한 자원을 흡수하셨다. 동양의 전통적인 유불선 삼교를 가장 중요한 종교와 문화형태로 인정하시고, 그 삼교의 내용을 두로 포용하셨으며, 심지어 예수교와 서양문화까지 모두 아우르는 태도를 보여주셨다. 서양의 문화 역시 증산께서 추구하시는 신세계의 한 부분이었기 때문이다. 이러한 사실은 증산께서 당시 세계의 역사적 방향에 대해 통찰하고 있었고 이 통찰 속에서 종교 간의 관계가 조화롭게 되어야 함을 주창했음을 말해 준다. 대순사상에는 민간 무교의 내용 역시 풍부하게 들어있다. 부뚜막신, 사명, 아표신, 마장군, 백의군왕, 황천신 등 민간에서 유행했던 다양한 신령숭배의 내용을 흡수했을 뿐만 아니라, 주문과 부를 태우는 법술로 신명과 관련된 내용을 표현하고 있으며, 칠성과 관우의 신앙까지 수용하고 있다. 또한 증산 성사는 동학과 같은 신종교까지 받아들이셨다. 증산께서는 동학혁명의 비참한 최후를 완화시켰던 위대한 역사적 공적을 이루셨으며, 신종교 운동의 사회적 형태를 변화시켰을 뿐 아니라, 서로 다른 내력을 지닌 교도들간의 관계를 조화롭게 하였다. 이로 볼 때 결국 증산께서 주창한 대순사상은 사람들 간의 충돌과 모순을 소멸시키고, 조화와 상생의 사회 환경을 창조하고자 하는 것이었다고 할 수 있다.

In the face of revolutionary changes in industry, the relationship between labor and income needs to be reconceptualized in the period of social revolution. The absolute decrease in labor due to the absence of labor is caused by automation, smartization, AI, robot labor, etc., which we must accept whether we want to or not. However, while gross social product and capital of the state or society increase, individual income is likely to decrease. During this transformation period, the state or politics must prepare for the problems caused by the decline in individual income. Until now, there have been various levels of discussion on social welfare or social security from the perspective of welfare or assistance. Attempts or studies at the experimental level have been conducted at the level of many countries or local governments and have found positive and negative effects. There is no basic income system that is widely implemented at the national level, and various discussions are taking place from a future-oriented perspective. Therefore, I propose to look at it from a new perspective based on the perspective so far. We explored that it is part of a positive approach to examine the importance and necessity of basic income in terms of working hours, quality of labor, income, quality of life, value of spare time, and work-life balance. The goal is to actively accept the absolute lack of working hours, replacement of mechanical labor, and polarization due to changes in the industry paradigm, and to look at the problems that come from a positive perspective. If we are going to accept it anyway, we should not look at these issues as short-sighted, but prepare them preemptively and establish a primitive plan from a long-term and overall perspective. Smartphones have changed the world over the past decade and have been lost, but wouldn't there be a lot of new discoveries? Shouldn't we think of it as a great opportunity to improve the quality of life through technological changes?

Purpose: To improve the management of a medical linear accelerator, the records of operational failures of a Varian CL2l00C over a ten year period were retrospectively analyzed. Materials and Methods: The failures were classified according to the involved functional subunits, with each class rated Into one of three levels depending on the operational conditions. The relationships between the failure rate and working ratio and between the failure rate and outside temperature were investigated. In addition, the average life time of the main part and the operating efficiency over the last 4 years were analyzed. Results: Among the recorded failures (total 587 failures), the most frequent failure was observed in the parts related with the collimation system, including the monitor chamber, which accounted for $20\%$ of all failures. With regard to the operational conditions, 2nd level of failures, which temporally interrupted treatments, were the most frequent. Third level of failures, which interrupted treatment for more than several hours, were mostly caused by the accelerating subunit. The number of failures was increased with number of treatments and operating time. The average life-times of the Klystron and Thyratron became shorter as the working ratio increased, and were 42 and $83\%$ of the expected values, respectively. The operating efficiency was maintained at $95\%$ or higher, but this value slightly decreased. There was no significant correlation between the number of failures and the outside temperature. Conclusion: The maintenance of detailed equipment problems and failures records over a long period of time can provide good knowledge of equipment function as well as the capability of predicting future failure. Wore rigorous equipment maintenance Is required for old medical linear accelerators for the advanced avoidance of serious failure and to improve the qualify of patient treatment.

Muscovite and biotite from 52 metasediments and 5 granites in the Hwasan area, the southwest of the Okcheon metamorphic belt and the Miwon-Jeungpyeong area, central Okcheon metamorphic belt were dated by the K-Ar and $^{40}$ Ar/$^{39}$ Ar methods. Muscovite and biotite ages from metapelitic and psammitic rocks (metasediments) of the Boeun and Pibanryeong units in the Hwasan area are concentrated in the mid-Jurassic (149-180 Ma). K-Ar and $^{40}$ Ar/$^{39}$ Ar ages for metapelitic and psammitic rocks of the Boeun and Pibanryeong units in the Miwon-Jeungpyeong area show complicated age distribution. Muscovite and biotite ages are classified by three groups, 142-194 Ma, 216-234 Ma, and 241-277 Ma. Younger (Cretaceous) ages occur only in metasediments close to Cretaceous granitic rocks in the southeastern region and the older ages of 216-277 Ma are restricted to the middle Part of the Jeungpyeong area. Most ages in the other area of the central Okcheon metamorphic belt fall between 142-194 Ma (Jurassic). K-Ar and $^{40}$ Ar/$^{39}$ Ar ages for granite from the northern part in the both the southwest and central Okcheon metamorphic belt also gave middle Jurassic ages (156-168 Ma). The similar ages from both metasediments and granites in the study areas indicate simultaneous cooling of both rocks to 300-350$^{\circ}C$ during the middle Jurassic. The state of graphitization of carbonaceous material of all metasediments in the study areas Indicates fully ordered graphite falling within a small range, from 3.353 to 3.359 ${\AA}$, which indicate amphibolite facies regional metamorphism. In the southern sector of the Boeun unit from the Hwasan area, metamorphic grade indicated by mineral paragenesis during regional intermediate-P/T metamorphism is greenschist facies. Whereas, the $d_{002}$ values for carbonaceous materials in the same sector show fully ordered graphite (ca. 500$^{\circ}C$) indicating amphibolite facies. This result with the concentration of mica ages of metasediments into the middle Jurassic, the presence of low-P/T thermal metamorphic zone (>500$^{\circ}C$) in the metasediments close to the Jurassic granite and the regional intrusion of Jurassic granites and their middle Jurassic intrusion and cooling ages may indicate the low-P/T regional thermal event during the early(\ulcorner)-middle Jurassic after main intermediate-P/T metamorphism which formed main mineral assemblage regionally in the study area. The regional thermal event failed, however, to reset the mineral assemblage of regional intermediate-P/T metamorphism except for narrow aureole (1-2 km) around Jurassic granite because e duration of thermal effect was relatively short by repid cooling of the Jurassic granite. In the middle part of the Jeungpyeong area, central Ogcheon metamorphic belt, muscovite and biotite K-Ar ages from 5 samples are 263-277 Ma and 241-249 Ma, respectively. An intermediate-P/T metamorphism is currently accepted to have occurred between 280 and 300 Ma. Therefore, the muscovite and biotite ages can be interpreted as cooling ages after Ml metamorphism indicating rapid cooling to ca 350$^{\circ}C$ between 280-300 Ma and 263-271 Ma, and biotite ages indicate slower cooling to ca. 300$^{\circ}C$ between 263-277 Ma and 241-249 Ma. However, more detail study is needed to confirm why the Permian to Triassic ages occur only in the middle Part of the Jeungpyeong area.a.

Purpose : $Henoch-Sch{\ddot{o}}nlein$ purpura(HSP) is the most common and benign systemic vasculitis in children. Few reports have focused on worse outcomes of HSP in adults. The age of onset is suggested as a main risk factor. We assessed the characteristics of adolescent-onset HSP. Methods : We retrospectively analyzed 205 cases presented from Aug. 1993 to Oct. 2003. Patients were classified as children(<10 years of age), adolescents(10-20 years of age), and adults(>20 years of age). Results : The mean age was $5.7{\pm}1.8years$ in 149 children, $13.5{\pm}2.4years$ in 38 adolescents, and $44.9{\pm}14.5years$ in 18 adults. The male to female ratio was 1.2 : 1 in children and adolescents, and 2 : 1 in adults. Previous upper respiratory infections were found in 53.4 percent of children, 32.4 percent of adolescents, and 33.3 percent of adults. Positivity of stool occult blood was more frequent in adults(50.5 percent) than in children(23.0 percent)(P<0.05). Renal involvement was found in 46 cases (30.9 percent) of children, 23 cases(60.5 percent) of adolescents, and 15 cases(83.3 percent) of adults. Recurrences occurred in 23 cases(15.4 percent) of children, nine cases(23.7 percent) of adolescents, and three cases(16.7 percent) of adults. Among the cases with renal involvement, 97.8 percent of children and 87.0 percent of adolescents improved to normal or asymptomatic urinary abnormalities. 60.0 percent of adults persisted with severe nephropathy and 13.3 percent progressed to renal insufficiency. Conclusion : Although the outcome of adolescent HSP was as good as children, the clinical manifestations were similar to those of adults. Adolescents had the highest rate of recurrences. Thus long term observations may be needed in adolescent onset HSP.

Purpose : Enterobiasis is probably one of the most common parasitic infection world-wide. Human is the only known host of Enterobius vermicularis. Children are more commonly infected with Enterobius vermicularis than adults and infections are commonly recurred. In Korea, there is a high prevalence. So, we performed this study to evaluate the present status of Enterobius vermicularis infection among children in the Masan, Changwon areas and to determine the efficacy of flubendazole against this parasitic nematode. Methods : From November to December, 1997, urban and rural elementary school children and urban preschool children were examined for the presence of Enterobius vermicularis egg. All the children were examined once by an adhesive cellotape anal swab technique in the early morning at home by their parents guided by specific instructions for the technique. Results : 1) A total of 644 adhesive cellotape anal swab specimens was collected from 205 urban elementary school children, 290 rural elementary school children and 145 urban preschool children. Among them, 114(17.7%) were positive for Enterobius vermicularis eggs. There was no significant differences in the rate with regard to sex. 2) In the preschool children, the egg detection rate was 42(29.0%) out of 145 children. This rate was significantly higher compared with 72(14.4%) of 499 school children. 3) The egg detection rates in the rural and urban school children were 15.2, 13.7% respectively. There was no significant difference in both groups. In the 3rd grade and below in elementary school children, there was a higher rate compared with above 4th grade group. 4) In day care center where egg detection rate was high as 41%, the children were given two doses of 100mg flubendazole every 3 weeks, including staffs and family members. After treatment, egg detection rate fatted as 6%. Conclusion : Our data demonstrated that there was high prevalence of Enterobius vermicularis infection. In the light of these results, it is necessary to examine and treat children as soon as possible.

The scaling properties on the length distribution of microcrack populations from Tertiary crystalline tuff are investigated. From the distribution charts showing length range with 15 directional angles and five groups(I~V), a systematic variation appears in the mean length with microcrack orientation. The distribution charts are distinguished by the bilaterally symmetrical pattern to nearly N-S direction. The whole domain of the length-cumulative frequency diagram for microcrack populations can be divided into three sections in terms of phases of the distribution of related curves. Especially, the linear middle section of each diagram of five groups represents a power-law distribution. The frequency ratio of linear middle sections of five groups ranges from 46.6% to 67.8%. Meanwhile, the slope of linear middle section of each group shows the order: group V($N60{\sim}90^{\circ}E$, -2.02) > group IV($N20{\sim}60^{\circ}E$, -1.55) > group I($N60{\sim}90^{\circ}W$, -1.48), group II($N10{\sim}60^{\circ}W$, -1.48) > group III($N10^{\circ}W{\sim}N20^{\circ}E$, -1.06). Five sub-populations(five groups) that closely follow the power-law length distribution show a wide range in exponents( -1.06 - -2.02). These differences in exponent among live groups emphasizes the importance of orientation effect. In addition, breaks in slope in the lower parts of the related curves represent the abrupt development of longer lengths, which is reflected in the decrease in the power-law exponent. Especially, such a distribution pattern can be seen from the diagram with $N10{\sim}20^{\circ}E,\;N10{\sim}20^{\circ}W$ and $N60{\sim}70^{\circ}W$ directional angles. These three directional angles correspond with main directions of faults developed around the study area. The distribution chart showing the individual characteristics of the length-cumulative frequency diagrams for 15 directional angles were made. By arraying above diagrams according to the categories of three groups(A, B and C), the differences in length-frequency distributions among these groups can be easily derived. The distribution chart illustrates the importance of analysing microcrack sets separately. From the related chart, the occurrence frequency of shorter microcracks shows the order: group A > group B > group C. These three types of distribution patterns could reveal important information on the processes occurred during microcrack growth.
