Recently, the satellite industry has been paying attention to the private-led 'New Space' paradigm, which is a departure from the traditional government-led industry. The space industry, which is considered to be the next food industry, is still receiving relatively little attention in Korea compared to the global market. Therefore, the purpose of this study is to explore future signals that can help determine the market entry strategies of private companies in the domestic satellite industry. To this end, this study utilizes the theoretical background of future signal theory and the Keyword Portfolio Map method to analyze keyword potential in patent document data based on keyword growth rate and keyword occurrence frequency. In addition, news data was collected to categorize future signals into first symptom and early information, respectively. This is utilized as an interpretive indicator of how the keywords reveal their actual potential outside of patent documents. This study describes the process of data collection and analysis to explore future signals and traces the evolution of each keyword in the collected documents from a weak signal to a strong signal by specifically visualizing how it can be used through the visualization of keyword maps. The process of this research can contribute to the methodological contribution and expansion of the scope of existing research on future signals, and the results can contribute to the establishment of new industry planning and research directions in the satellite industry.

Objectives: Outbreaks of pneumonia caused by Mycoplasma pneumoniae (MP) occur every 3-4 years in Korea, most recently in 2011. The aim of our study was to determine the optimal time to perform indirect particle agglutination antibody assays to improve early diagnosis of MP pneumonia in children. Methods: A database of 206 pediatric patients treated for pneumonia at the Hanyang University Hospital from June to October 2011 was analyzed retrospectively for demographic characteristics and laboratory test results. Results: Among the 206 patients treated for pneumonia during the study period, there were 160 children (mean age, 5.44 years) diagnosed with MP pneumonia, who were studied further. The mean age of these MP pneumonia patients was 5.44 years. Antibody titers increased with increasing time between symptom onset and the collection of serum collection: MP titers were <1:640 for sera collected after 5.44 days and titers ${\geq}1:640$ for those collected after 8.58 days; P<0.001). Antibody titers were considered positive when they reached ${\geq}1:640$. In 42 MP pneumonia patients in whom there was a four-fold or greater increase in titer between successive serum samples, the optimal cut-off time-point for distinguishing between the initial and second titer groups was 7.5 days after the onset of symptoms (sensitivity, 90.5%; specificity, 92.9%). Conclusions: Negative MP antibody titers earlier than 8 days after the onset of symptoms in children with pneumonia may require repeating to confirm the diagnosis. This finding could optimize diagnosis and result in better therapeutic outcomes of MP pneumonia in children.

1799 Francisco de Goya published Los Caprichos with 80 aquatint etchings. On 6 February he advertised it on the front page of the Diario de Madrid. The long advertisement which began with "a collection of prints of capricious subjects, invented and etched by Don Francisco Goya" informed purpose, themes and methods of this collection of prints. According to this advertisement Goya "has chosen as subjects for his work, from the multitude of follies and mistakes common in every civil society and from the vulgar prejudices and lies authorized by custom, ignorance or self-interest, those that he has thought most fit to provide material for ridicules, and at the same time to exercise the artist's imagination." The text emphasized that the 'author' of this series didn't to want to criticise any individual and to be a copyist. From his phantasy Goya invented many creatures like the anthropic, humanized animals etc.. With Los Caprichos he stood on the threshold to Romanticism. The early researchers of Los Caprichos classified its author, Goya as an enlightened intellectual. The similarity of the themes of the series with the subjects of the Enlightenment, his some enlightened 'friends' and the idea to avoid the prevalent mystification of his life supported this theory. But this trend became revised since the 80's of the last century. This made possible to research Goya's works in new perspective and to see that Goya didn't criticise the Spanish society and his contemporaries. Rather he showed its reality and parodied through creatures which are mixtures of the reality that he observed, and visions that he invented. Characters and scenes in Goya's prints are ambiguous and equivocal. They have the values which are defined by the dualistic metaphysic in Europe as oppositional, like good and evil for example, at the same time. Goya himself also appeared in various types in this series. This ambiguousness, or "polyphony", as Jennis Tomlinson defined, is a symptom of the decay of the belief in the Enlightenment which spreaded in Europe as a result of the attack of Bastille and the French Revolution. Goya's self-portrait in pl. 43 of this series, "El sue$\tilde{n}$o de la razon produce monstruos" shows the complex psychology of him and his contemporaries as well. As the rest etchings after this print show witchcraft and monsters reside in the world in which the reason of the Enlightenment and the through the reason weakened God's rule lost their authority. In this thesis I will examine and analyse how Goya represented in Los Caprichos the nature of man and its society, as complex being in which the 'antagonistic' value couple as good and evil couldn't be divided, but are united.

This study is to provide basic data regarding prevention of VDT syndrome by surveying the computer usage and understanding the VDT subjective symptoms. Data collection was done using a structured questionnaire among 617 students in middle and high schools in J city, Chonbuk province from 1 April 2002 to 20 April 2002. Modified and adjusted study tools were used which were based on previous studies on the actual computer usage and the VDT subjective symptoms, and the self-assessment tool for VDT syndrome by Moon et al(1991). Collected data were analyzed by SPSS program. The results were as follows: It showed 97.2% of students in middle schools and 97.6% in high schools to hold personal computer, 92.2% of middle school students and 84.7% of high school students commonly used computer at home. Communication was the obvious reason to use computer in 55.8% of middle school students and 71.6% of high school students. The mean of the VDT subjective symptoms among students in high schools showed $1.09{\pm}.69$ which higher than that of $.80{\pm}.59$ among students in middle schools (t=5.666, p=.000). Musculoskeletal symptom was marked the highest in the scoring of VDT subjective symptoms among students in middle and high schools. The higher grade, The more pocket money, The less breaks or exercise taken during computer use, The more they feel harmful about using computer, The actual time of computer longer than 3 hours per use were contributed to the higher score of the VDT subjective symptoms among students. There are suggestions following this study: To establish a systematic preventative program and management regarding the current computer use among students especially in relation to the VDT subjective symptoms. To develop better educational programs for parents regarding time-limit and to create appropriate environment in computer use.

Since 2008, a new leaf spot disease has been found in loquat tree (Eriobotrya japonica) at a nursery station in Goheung, Korea. Above 50% of the seedlings developed the spot symptoms on the leaves. The infected plants were generally reduced in the seedling vigour and early defoliation was occurred. The infected leaves developed grayish lesion with dark reddish brown margin. The pathogen developed round to ellipsoidal acervuli on the lesion. Based on morphological characteristics of the pathogen, the fungus was identified as Entomosporium mespili. The cultured pathogen successfully reproduced the same disease symptom on the leaves of loquat tree and found to be E. mespili. A monoconidial culture was deposited in Korean Agricultural Culture Collection (KACC 44727). This is the first report of E. mespili causing leaf spot of loquat tree in Korea.

In July 2019, typical rot symptom was observed on peach fruits harvested from the fields at Andong, Korea. As the disease progressed, white and purple colored mycelial mat developed on the surface of the infected fruits. A causal pathogen was isolated from the infected fruit and cultured on potato dextrose agar media for identification. Fungal colonies on potato dextrose agar produced 3 pigments, including purple, yellow, and white colors. The isolate incited fruit rot symptoms on artificially inoculated peach fruits, from which the same fungus was isolated, fulfilling Koch's postulates. Based on the morphological characteristics and sequence analysis of rDNA internal transcribed spacer, translation elongation factor 1-alpha, and β-tubulin, the causal agent of the disease was identified as Fusarium avenaceum. This study is the first report of fruit rot of peach fruits caused by Fusarium avenaceum in Korea.

Objectives : The purpose of this study is to examine the effects of the characteristics of victim and sexual abuse on posttraumatic psychiatric symptoms in children and adolescents with a history of sexual abuse. Methods : A total of 137 children and adolescents were recruited from the Seoul Sunflower Children Center, a nation-funded sexual violence victim protection center, from January 2009 to December 2013. We collected the demographic data of the victims and the Trauma Symptom Checklist for Children (TSCC) from victims. We hypothesized victims' age, sex, and intelligence quotient, and the characteristics of sexual abuse as the affecting factors of posttraumatic psychiatric symptoms. Descriptive analysis and hierarchical regression analysis were performed for analysis of demographic data, TSCC scores, and psychiatric symptoms. Results : The victims' age and the characteristics of sexual abuse were significantly related to the traumatic distress of sexual abuse. R-square was 23% for anxiety, 39% for depression, 21% for posttraumatic stress, and 37% for dissociation on TSCC. Conclusion : This study suggests that victims' age, type, frequency and duration of exposure, and disclosure of sexual abuse are significant affecting factors on posttraumatic psychiatric symptoms in children and adolescents. Exploration of psychiatric symptoms other than posttraumatic symptoms, and relations between pretraumatic and posttraumatic psychiatric symptoms is needed through collection of larger samples.

Objectives This research was proposed to present clinical practice guideline (CPG) for Taeyangin Disease of Sasang Constitutional Medicine (SCM). This CPG was developed by the national-wide experts committee consisting of SCM professors. Methods This guideline was performed that search and collection of literature related SCM such as "Dongeuisusebowon", textbook of SCM, clinical guidebook of SCM and fundamental research to standardize diagnosis of Sasang Constitutional Medicine. Journal search related clinical trial or human complementary medicine of SCM was performed domestic and overseas. Finally, 1 article was selected and included in CPG for Taeyangin disease. Results & Conclusions The CPG of Taeyangin disease include classification, definition and standard symptoms of each pattern. Taeyangin disease is classified into exterior-origin lower back (EOLB) disease and interior-origin small intestine (IOSI) disease by region of symptom. EOLB can be replaced with Oegam-yocheok and IOSI can be replaced with Naechok-sojang that is Korean pronuncation. EOLB disease is classified into lower back favorable symptomatology (LBFS) and lower back unfavorable symptomatology (LBUS). Lower back is to say Yocheok, so LBFS can be called Yocheok favorable symptomatology and LBUS can be called Yocheok unfavorable symptomatology. LBUS is to say paraparesis symptomatology or Haeyeok, that is Korean pronunciation, symptomatology. IOSI disease is classified into small intestine favorable symptomatology (SIFS) and small intestine unfavorable symptomatology (SIUS). Small intestine is to say Sojang, so SIFS can be called Sojang favorable symptomatology and SIUS can be called Sojang unfavorable symptomatology. SIUS is to say regurgitation symptomatology or Yeolgeok, that is Korean pronunciation, symptomatology.

This study examined 19 papers published from 1977 to 2000 based on the objective frame evaluation. This purpose of this study was to examine the trend of Hwabyung research and to serve as a guide for the future 'Hwabyung' study. The results of studies were as follow. In the design of research, clinical studies are definitely dominant. As for the fields of research, the concept of Hwabyung was studied more frequently than the others. As for the authorship. psychiatrists prevailed but nursing professionals are on the increase. Research subject in clinical and survey study, patient was definitely dominant and the place of study was almost always a hospital (75%), data collection was higher on interview (58.3%). Hwabyung was considered unique culture bounded syndrome related to Korean culture. Frequent etiologic factor of Hwabyung were a husband's extra-marital affair, conflicts between houses wives and mothers-in-laws, and financial loss and suffering. From the incidence of Hwabyung, a greater number of patients with Hwabyung were middle aged women in the low economic and educational classes, and these were connected with the culture and the family system. The symptoms of Hwabyung included psychological and physical symptom, neurological disorder and disease behavior. Defense mechanisms and coping strategies for Hwabyung were somatization, suppression, orality, withdrawal, isolation, regression, help-seeking, complaining, and wreaking anger. Treatment of Hwabyung were medication, effort by herself, communication with families, consultation with psychologist, acupuncture, negative therapy, moxa, and Qi-kong. Psychiatric therapy, behavior therapy, nursing intervention on multi-interdisciplinary approach and psychiatric nursing approach were recommended for the nursing care of a Hwabyung patient.

Purpose: The purpose of this study was to identify the prevalence of irritable bowel syndrome and factors related to irritable bowel syndrome (IBS) in university students. Methods: A cross-sectional, descriptive study was conducted using a self-report structured questionnaire with 420 university students. Data collection was done during May and June, 2017. The data were analyzed using descriptive statistics, a t-test, $x^2$ test, and binary logistic regression analysis with IBM SPSS/WIN 22.0 program. Results: The prevalence for IBS was 24% among Korean university students. Family history of IBS (OR=2.98, 95% CI=1.32~6.70), history of stomach and intestinal disease (OR=2.24, 95% CI=1.36~3.77), sleep quality (OR=2.01, 95% CI=1.16~3.48), mild anxiety (OR=2.75, 95% CI=1.19~6.33) and more than moderate anxiety (OR=2.02, 95% CI=1.02~4.00) were found to be factors related to IBS. Conclusion: The prevalence of IBS was high among university students, and sleep quality and anxiety significantly influenced prevalence of IBS in these students. Therefore, interventions to decrease symptom of IBS must focus on management of sleep quality and anxiety.
