  • The objective of this study is to find the failure factors of venture companies. We analyze 210 troubled venture companies, all of which have been under guarantee from the Korea Technology Finance Corporation over the last three years. Methods of analysis for failure factors are as follows. First, we categorize the failure factors into the four different types based on growth and profitability indicators in the financial statements of targeted venture companies. Then we analyzed the failure factors of the subject companies based on the troubled guarantee reports made by the Korea Technology Finance Corporation. If a venture company under its guarantee program falls into insolvency, the Korea Technology Finance Corporation make the troubled guarantee report to find out the failure factors and evaluate the recovery potentials. We identify 374 failure factors of venture companies through the analysis. The most prominent among them are deteriorating of business environments (79 factors) and decreasing or withdrawing orders from major suppliers (54 factors) due to bankruptcies or change in business plans. They are followed by slowing collection of accounts receivable (31 factors), dropping or frozen product price (24 factors) due to intensifying competition and escalating pressures from major suppliers, rising raw material costs both at home and abroad (21 factors). In addition, the nuclear power plant disaster in Japan, shut-down of the Kaesong Industrial Complex and subsequent lawsuits, delay in technology development projects, high cost-low efficiency management structure, etc., are also revealed as new factors causing trouble for venture companies.

  • The partial endocardial cushion defect including ostium primum atrial septal defect and anterior mitral leaflet cleft, presents less significant clinical symptoms than complete endocardial cushion defect. But, as mitral insufficiency develops, cardiomegaly, congestive heart failure, pulmonary arterial hypypertension appear. So, partial endocardial cushion defect has poor prognosis and is rarely seen in elderly patients. A 67 years old woman admitted at our hospital for operative treatment with partial endocardial cushion defect. She had increased pulmonary pressure of 45/22 mmHg, mean 32 mmHg. She had repair of ostium primum defect with patch, and the mitral valve was treated with valve replacement. Because advanced atrioventricular block developed postoperatively, she received permanent pacemaker.

  • Objectives: Shoulder pain is the third most common musculoskeletal complaint that necessitates physician consultation and significantly diminishes patients' quality of life. In this review, we analyzed clinical studies that investigated the use of Korean Medicine for the treatment of shoulder pain. Methods: We searched the online Korean databases, such as KMBase, DBpia, NDSL, RISS, KISS, and OASIS for clinical studies that report the use of Korean Medicine for shoulder pain. We analyzed the included studies with regard to study design, interventions, evaluations, and results. Results: We analyzed data from the following 29 studies: 14 clinical trials (which included 9 randomized controlled trials) and 15 observational studies (which included 11 case reports). In this review, we observed that post-stroke shoulder pain was the most common cause of shoulder pain, which was reported in 13 out of 29 studies (44.8%), although in actual clinical practice, patients are more likely to present with primary shoulder pain. Most included studies (72.4%) reported manual acupuncture as the most common intervention for shoulder pain. More than 50% of the studies used range of motion (58.6%) and the numeric rating scale (51.7%) to evaluate shoulder function and pain, respectively. Although the result was not statistically significant in all included studies, most studies concluded that Korean Medicine could be considered an effective treatment option in patients with shoulder pain. Conclusions: Based on analysis of studies included in this review, Korean Medicine can be considered useful clinical treatment for shoulder pain.

  • This report investigates the economic proprieties of commercial 50,000 barrel per day direct/indirect coal liquefaction(DCL/ICL) plants to produce commercial-grade diesel and naphtha liquids. The scope of the study includes capital and operating cost estimates, sensitivity analyses and a comparative financial analyses. Based on plant capacity of 50,000BPD, employing Illinois #6 bituminous coal as feed coal, the total capital cost appeared $3,994,858,000(DCL) and $4,962,263,000(ICL). Also, the internal rate of return of DCL/ICL appeared 13.27% and 12.68% on the base condition respectively. In this case, coal price and sale price of products were the most influence factors. And ICL's payback period(6.8 years) was longer than DCL's(6.6 years). According to sensitivity analyses, the important factors on both DCL/ICL processes were product sale price, feed coal price and the capital cost in order.

  • Objectives : The aim of this review is to investigate studies on skin adverse reactions and to demonstrate subjects related to the adverse effects in dermatology. Methods : Electric searches were performed with KISS(Korean studies Information Search System) and the key words were combination of 'skin' and 'adverse effect'. 87 literatures investigated in this review were issued from 1900 to 2016. Results : Among the 87 papers, dermatologic adverse reactions were reported in 83 papers in medicine, accounting for 95.4%. Of the adverse effects seen on the skin, 84 discoloration such as erythema, pigmentation and hemotelangiosis were the most common, accounting for 21%. Among the medical adverse reactions not seen on the skin, 21 infection were the most common, accounting for 25%. Among the subjective adverse reactions, of which 32 pruritus were the most common, accounting for 43%. Among the 87 papers, there were 3 cases with underlying diabetes and 3 cases with underlying hypertension, followed by 2 cases with chronic renal failure, HBV, atopic dermatitis and respectively 1 case with alcoholism, depression addiction, multiple myeloma, arthritis and psoriasis. The most frequent period until adverse reactions appeared was within 2 weeks, accounting for 13 papers. And 4 were the most frequent adverse reactions lasting less than 1 month, and 4 were more than 3 months and less than 6 months. There were 48 cases where adverse reactions were caused by nonmedical practioner's treatment. The adverse reactions by the pharmacist were the highest at 11 cases (23%). There were 17 cases of adverse reactions due to medical treatment, among which dermatologists and nondermatologists accounted for the majority of 5 cases, 29%. The most common cause of adverse reactions was the application of external medicine (41 cases), followed by 36 cases of foreign body implantation, eyebrow tattooing, ear piercing, etc. Conclusions : In this report, we demonstrated patterns of adverse reactions in the medical field of dermatology caused by non-medical personnel than medical personnel. We suggest that more effort should be followed by medical personnel to establish clear awareness of skin disease and by patients to be aware of the risks of the illegal medical treatment by non-medical personnel.

  • 50 days old, 4.5kg male patient was admitted at department of pediatrics due to congenital heart disease with congestive heart failure. The echocardiographic finding was perimembranous type ventricular septal defect. The patient underwent open heart surgery for patch closure of VSD. Immediately postoperatively, junctional ectopic tachycardia developed and the patient was in hemodynamically unstable state with decreased urine output. We used inotropics, digitalis and diuretics, however these treatments were not effective in recovering the unstable state. Therefore, we tried a mild hypothermic treatment(34℃). During the POD #2, mild hypothermia method was repeated four times. The junctional ectopic tachycardia was converted to normal sinus rhythm, hemodynamic state was stable, and urine output was increased. The patient was discharged at POD #8.

  • Objectives The present study examines the domestic trend of Failed Back Surgery Syndrome (FBSS) in Korea. Methods The studies on FBSS were investigated via searching Korean web databases. As a result, 41 research papers were found and they were analyzed according to the year of publishment, the titles of journals which have the papers, the types of study, the definition of FBSS, employed treatment trials, and the instruments for assessment. Results The number of the research papers on FBSS published was increased since 2005. The studies on FBSS were mainly published in the Korean Journal of Pain. The most popular type of the studies were the case report and the most studies defined FBSS as persistent or recurring low back pain with or without sciatica after receiving spine surgeries. Various surgical and conservative treatments were employed in the studies and Visual Analogue Scale (VAS), Numeric Rating Scale (NRS), Oswestry Disability Index (ODI) were used as primary means of assessments. Conclusions Reviewing the domestic trends of studies on FBSS and examining the definition of FBSS is essential for the future studies because there is no clear criteria for making diagnosis of FBSS. Therefore, the further studies on FBSS need to be more elaborate with the definition of FBSS, and it is also necessary to apply more assessment tools for the better understanding of FBSS from various aspects. Ultimately, this review is anticipated to benefit the future in-depth study on FBSS.

  • Objectives: This study was performed to analyze cases of food poisoning outbreaks reported in Chungcheongnamdo Province in 2019 and report it as effective data for preventing food poisoning in the future. Methods: Food poisoning outbreaks were analyzed to detect virus, bacteria, and protozoa according to the Manual for Detection of Foodborne Pathogens in Outbreaks to clarify the causes of food poisoning that occurred in Chungcheongnam-do Province in 2019. Results: Among the 79 cases of food poisoning outbreaks, 59 cases (74.7%) were in general restaurants, 15 cases (19.0%) in food service institutions, three cases at banquets, and two cases in take-out food. The 42 cases at general seafood restaurants made up the majority of food poisoning in Chungcheongnam-do. Food poisoning pathogens were shown in 13 cases (86.7%) out of the 15 cases at food service institutions, and 10 cases were related to Norovirus. Among the 79 cases, food-borne pathogens were identified in 35 cases of outbreaks, accounting for 44.3%. The confirmed pathogens were as follows: bacteria (24 cases), Norovirus (12 cases) and Kudoa septempunctata. (five cases). The food-borne bacteria were pathogenic E. coli (12 cases), Staphylococcus aureus (six cases), Salmonella spp. (two cases), Campylobacter jejuni, Bacillus cereus, Clostridium perfringens, and Vibrio parahaemolyticus (one case). Conclusions: To prevent food poisoning, it is necessary to analyze regional characteristics and environments and to hold a campaign for the prevention of food poisoning based on that analysis. In addition, when food poisoning occurs, the results of analyzing its cause and spread based on accurate epidemiological survey need to be shared.

  • Nursing process is an essential part for nursing practice. Nursing faculty members must focus on the clinical application for students and try to identify the possible problems that students might face in the fields. The purpose of this study is to examine the actual condition of nursing process education in curricula and to investigate the response of students in clinical experience of nursing process. From 462 students in the 6 associate programs(ADN) and the 6 baccalaureate programs (BSN) data was collected by questionnaire. The results were as followed. 1. Seven programs (58.3%) opened the nursing process in mainly sophomore (BSN) or freshman(ADN). If not opened, the nursing process was taught at the major subjects(espcially fundamental nursing or adult nursing). 2. All Students responded they we supposed to use nursing process in preparing the case report. The majority(94.6%) used NANDA lists for nursing diagnosis and 55.7% of subjects consulted the Korean terms by KNA when translating. The tutors for nursing process in clinical settings were the professor in charge of the subject (68.6) or clinical instructors (48.1%) , assistants(34%). 3. The problems in clinical application that students experienced consisted of 17 items and the mean was 2.27. The biggest problem was 'the lack of the model for RN of applying the nursing process in clinical settings'(2.97). Next the big problem was 'the lack of the competency for implementing the established nursing plans'(2.69). All items were significantly different according to the level of educational programs(ADN or BSN). ADN students had more problems in applying the each step of nursing process and BSN students perceived the NANDA as a guidance of nursing diagnosis and the inconsistency of advices from several instructors or practicum to be mere problematic. 4. The mean of merits after application of nursing process was relatively fair (2.82). The best merit was 'they can identify nursing problems more exactly'(3.07). The second high merit was 'they can study the rational of nursing action' (3.03). BSN than ADN and the subjects of second year than of one year in clinical experience perceived the use of nursing process to be better. Based on this results we need to enforce the application of nursing diagnosis in the class. The use of sample cases can be the efficient method. Students can identify the possible health problems for patient from the cases in imaginary world and discuss them each other. Also we can use the discussion session after practice every other day or as needed. All this is on the good interaction between tutor and student. We must consider to have enough time for student to seize the essence of the nursing process.

  • It is widely believed that the increase in the prevalence of dental erosion is due to soft drinks. The purpose of this study was to assess the influence of soft drinks and etchant on the erosion of tooth enamel and the effect of tooth brushing on the abrasion of eroded enamel, and the effect of milk, saliva and Tooth $Mousse^{(R)}$ on the remineralization. The changes in tooth enamel surface were observed by scanning electron microscophy. The results were as follows; 1. The pH of Coca-Cola and Chilsung-Cider were higher than the pH of FineEtch 37 and $Tyrian^{TM}SPE$. 2. The SEM photos revealed that the pattern of the surface eroded by Coca-Cola and Chilsung-Cider were more obvious than that eroded by etchants. 3. The results of remineralization by saliva, milk, Tooth $Mousse^{(R)}$ were not different from each other. 4. The remineralization by saliva decreased tooth brushing abrasion.
