Intraabdommal abscess usually causes distress with fever, leukocytosis, pain and toxicity. Diagnosis of intraabdominal abscess is occasionally difficult and It has high morbidity. However radiologic method, such as ultrasonography, CT scan, or RI scan are helpful to early detection of intraabdominal abscess. Among these methods, ultrasonography is a non-invasive technique and performed without discomfort to patient. And also differential diagnosis between cystic and solid lesion is very easy and sequential ultrasonography in same patient is valuable for the evaluation of treatment effect. We analyzed the ultrasonic features of 48 cases with intra-abdominal abscesses and the results are as follows; 1. In total 48 cases, the intra-abdominal abscesses were 30 cases, the retroperitoneal abscesses, 5 cases, and the visceral abscesses, 13 cases. 2. The causes of the intra-abdominal abscesses were perforating appendicitis (25 cases), postoperative complications (5 cases), pyogenic and amebic hepatic abscesses (13 cases), and the others (5 cases). 3. Round or oval shaped lesions were 26 cases (54%), irregular shape, 18 cases (38%), and multiple abscess formation in 4 cases (8 %). 4. The size of the lesions were between 5 and 10cm in diameter in 54% of total 48 cases, and the most frequent feature of the echo-pattern of the lesions was cystic with or without internal echogenicity (69%).

The purpose of this study is to identify the effect of ear acupressure therapy on premenstrual syndrome of the female college students. This research design of our study was a quasi-experimental design. Out of the 27 female college students, 13 were assigned to the experimental group and 14 to the control group. The data was obtained over 3 months from K college located in G city. The use of instrument to assess the premenstrual syndrome is Keele's VAS(Visual Analogue Scale) with the opening records. The subject of the experimental group received the ear acupressure therapy for 3 times for 60 days and the other control group did not get the ear acupressure therapy treatment. We analysed the data and extracted the values of percentage, mean, standard deviation, $x^2$-test, t-test, and Cronbach's ${\alpha}$ using SPSS program. The VAS score of the premenstrual syndromes before the ear acupressure therapy was 7.3(experimental group), 7.46(control group) but after the ear acupressure therapy, the VAS score of the premenstrual syndromes was 3.36(experimental group), 7.17(control group). The result of this study reveals that the ear acupressure therapy was effective in improving the symptoms of the female college students who had the premenstrual syndromes.

The prognosis of the laryngeal diseases is highly dependent on the early diagnosis and treatment. The biopsy finding is inevitable for the cofirmed diagnosis. A clinico-statistical survey of the biopsy result of the larynx in 142 cases was done at the Department of the Otolaryngology Seoul National University Hospital during a period of 3 yrs from 1973 to 1975. Results are as follows 1. Of the 142 cases, 109 cases (76.8%) were males and 33 cases (23.2%) females. Sex ratio was 3.3 : 1. 2. Age distribution shows 41 cases (28.8%) in 5th decade, 41 cases (28.9%) in 6th decade. 3. Chief complaint was hoarseness 127 cases (89.4 %), dysphagia 7 cases (4.9%) and sore throat, dyspnea etc. The time lag from the onset of hoarseness to the hospital was 2∼6 Months, 56 cases (44.0%), 6 Months∼l yrs, 34 cases (24%), within 2 Months, 17 cases (13.4%) and 15 cases (11.8%) were over 3yrs. Average time lag was 8.1 Months. 4. The site of laryngeal biopsy was 76 cases (53.3 %) from ture vocal cord, 23 cases (16.2%) from false vocal cord, and 19 cases (13.3%) from epiglottis. 5. Biopsy result was carcinoma in 69 cases (48.6%), laryngeal nodule in 20 cases (14.0%), laryngeal tuberculosis in 12 cases (8.4%) and non specific inflamation in 7 cases (5.0%). 6. 13.4% of the clinically impressed laryngeal carcinoma proved to be laryngeal tuberculosis, nonspecific inflammation etc.

Purpose: The rapid response team is a patient safety system that detects symptoms and signs of deteriorating inpatients and provides intervention and treatment. This study analyzed the factors influencing the activation time of the team. Methods: This is a descriptive correlation study that analyzed the electronic medical records of patients activated by the rapid response team. The collection period was from January 2014 to December 2017. We analyzed 278 pieces of data activated by the rapid response team for patients aged 16 years or older at C University S Hospital in Seoul. We employed the SPSS 23.0 program for data analysis. Results: The reasons for activation of the rapid response team were oxygen saturation of less than 90.0%, other causes, and change in consciousness. The most common diagnosis of activated patients was respiratory failure (32.4%). The average activation time was 153.43±286.05 min. The activation time was shortest during convulsions (13.29±7.32 min). For patients with a history of kidney disease (B=0.58, p=.008), in case of surgery (B=0.55, p<.001), if the first symptom is mediated by the physician (B=0.53, p=.007) the active time is often extended. On the other hand, activation time is reduced when consciousness changes (B=-0.51, p=.002), especially when oxygen saturation is below 90.0% (B=-0.64, p<.001). Conclusion: Based on the results of the study, it is expected that patients deteriorating in the general ward would be recognized early, which will help in the effective activation of the rapid response team.

Purpose Though many information systems researchers have made various attempts to investigate the relationship between information technology capability and firm performance from diverse perspectives, we have not come to a conclusion yet with some mixed results. In this research, focusing on the adoption of Enterprise Resource Planning (ERP) systems by firms as a proxy measure for information technology capability, we reexamine whether the association is significantly positive. Design/methodology/approach Previous research on this topic had some limitations to the samples and analysis method. Some research focused only on the 1990s or early 2000s, and other studies failed to adequately compare the impact of ERP adoption on firm performance between the treatment group and the control group. In this research, extending previous analysis approaches with the matched sample comparison of IT leaders and the control group, we attempt to apply propensity score matching in combination with difference-in-difference analysis with a sample of Korean firms that adopted ERP systems in the late 2000s. We match ERP adopters and non-adopters with propensity score matching and compare their financial performance with difference-in-difference estimation between the pre- and post-adoption periods. Findings According to our analysis, we find no positive and significant relationship between ERP adoption and firm performance in profit ratios. This research shows that, contrary to the era of proprietary information systems, standardized information systems today have no additional competitive advantages over competitors.

Acute respiratory distress syndrome(ARDS) is severe acute hypoxic respiratory failure state with dynamic impairment in oxygen and carbon dioxide transfer with the need for high levels of supplementary oxygen and a high minute ventilation. This syndrome is caused by pulmonary edema due to increased permeability of the alveolar capillary barrier by various factors. ARDS is an uncommon, but a potentially life-threatening complication. Therefore, immediate diagnosis and appropriate therapy must be performed. The present case is post-extubation ARDS immediately occurred in an orthognathic surgery patient who are healthy 19-year-old man. He rapidly recovered from ARDS without complication by early diagnosis and proper treatment. This case report was aimed to describe the process of the development, possible causes and the management of ARDS occurred in an orthognathic surgery patient

Objectives : This research was performed to investigate protective effect of Sophora Subprostrata against transient global ischemic damage after 5-min two vessel occlusion. Methods : Gerbils were divided into three groups: Normal group, 5-min two vessel occlusion (2VO) group, Sophora Subprostrata administrated group after 2VO. The CCAs were occluded by microclip for 5min. Sophora Subprostrata was administrated orally(12mg/ml) for 7 days after 2VO. The histological and immunohistochemistrical analysis was performed at 72 hours and 7 days after the surgery each. For histological analysis, the brain tissue was stained with 1% cresyl violet solution and Immunohistochemistry for BAX and Bcl-2 was carried out to examine effect of Sophora Subprostrata on ischemic brain tissue. Results : The results showed that (1) Sophora Subprostrata has the protective effect against ischemia in CA1 area of the gerbil hippocampus 7 days after 5-minute occlusion, (2) the treatment of Sophora Subprostrata inhibits the expression of Bax relatively after 2VO-induced ischemia. That protective effect of the Sophora Subprostrata seems to be performed by regulating the proportion of Bax and Bcl-2 protein, (3) in hypoxia/reperfusion model using PC12 cell, the Sophora Subprostrata extract has the protective effect against ischemia in the dose of $2{\mu}/m{\ell}$ and $20{\mu}/m{\ell}$.This study suggests that Sophora Subprostrata has neuroprotective effect against neuronal damage following cerebral ischemia in vivo with a widely used experimental model of cerebral ischemia in Mongolian gerbils and that Sophora Subprostrata regulates the proportion of Bax and Bcl-2 protein following ischemia. And, Sophora Subprostrata extract has protective effects also on a hypoxia/reperfusion cell culture model using PC12 cell. Conclusions : Sophora Subprostrata has protective effects against ischemic brain damage at the early stage of ischemia.

Oral malodor is a problem that traverses history, culture, race and sex. But, up to the present the study on prevalence of oral malodor in normal popualtion is short, especially there is no study on oral malodor prevalence in Korean. In our study, we investigated self-evaluation of oral malodor, self-rating intensity of oral malodor, patients efforts for curing their oral malodor, and degree of satisfaction with their efforts. Investigation was carried out on 368 public Koreans resident in a big city(174 males, 194 females), by method of self-reporting to prepared questionnaire. There was no difference in self-reporting prevalence of oral malodor in sexes(57.5% in male, 58.8% in female), and the prevalence rate was increased with aging. Self-rating intensity of oral malodor in oral malodor patients group(by self-reporting) was ranked in order of slight, weak, middle, strong in both sexes, but the number of self-rating strong female group is significantly larger than that of self-rating strong male group(9.3% in male, 17.9% in female). In question on duration of oral malodor, most subjects answered that their oral malodor was developed in certain circumstances(61.3% in male, 76.3% in female), and oral malodor-developing circumstances was ranked in order of in the early morning, in hunger state, in fatigue, in stressful situations. Subjects effort for curing their oral malodor was ranked in order of more tooth brushing, gum chewing, use of commercial product for oral hygiene, visit dental clinic, and rates of no effort subjects were 15.3% in males and 10.7% in females. The degree of satisfaction with their efforts for curing their oral malodor was very low, only 5.6% of males and 6.6% of females were answered that there were satisfactory improvement in their oral malodor. Collectively, our result revealed that prevalence of oral malodor in public Koreans and their interest in oral malodor were much higher than our anticipation, and that patients satisfaction with improvement in oral malodor was short of their expectations. Considering the life quality of patients suffering from oral malodor, we conclude that developments of more improved diagnostic tools and treatment methods for oral malodor is indispensable in future.

Objectives: Early diagnosis and treatment is the most important strategy to control malaria effectively. Microscopic examination of blood films is a traditional and standard method for diagnosing malaria, which takes a long time and needs expertise, Therefore, the alternative method, rapid diagnostic kit has been used for quick diagnosis in some counties, a highly infectious region by P. vivax. The purpose of this study was to evaluate the utility of malaria rapid diagnostic kit in Ganghwa county. Methods: The utility was evaluated by mean diagnosis time and sensitivity and specificity. For monitoring mean diagnosis time, 942 cases which were diagnosed for P. vivax were collected between 1998 and 2005, And for calculating sensitivity and specificity, 434 whole bloods in EDTA which were presented for P. vivax by microscopy and rapid diagnostic kit were collected between 2004 and 2005. Results: After malaria rapid diagnostic kit was used in 2003, mean diagnosis time has decreased to 3.36-3.14 day. The sensitivity and specificity of the rapid diagnostic kit was 98.2% and 98,5% and comparable to that of microscopic examination. Conclusions: The malaria rapid diagnostic kit is useful tool in a highly infectious region like Ganghwa county.
