To identify the factors influencing the charges per case of acute appendicitis and normal spontaneous vaginal delivery (NSVD), the personal data-base files and hospital-characteristics-reporting data files of Korea Medical Insurance Corporation were analyzed. One hundred and twenty-nine institutions were selected. The results of this study were as follows: 1. The differences of charges per case with respect to hospital ownership, location, and equipment levels were statistically significant. 2. The results of multiple regression analysis revealed that bed capacity was the most significant variable in both diseases. 3. Ownership was significant variable in acute appendicitis. In NSVD, ownership and hospital equipment level were statistically significant. In conclusion, bed capacity was statistically the most significant variable in the analysis of charges per case. And we thought that the results of this study would influence the policy of the hospital bed supply.

The taxonomy of the Alternaria spp. has been a subject, of controversy because of their high variability in conidial morphology and polymorphism displayed even in pure cultures. The published Korean literature on the genus Alternaria is scattered and fragmentary, and pertains to about 25 species with special emphasis on occurrence and pathogenicity, but mycological studies on this group of fungi are insufficient. This is the first series of detailed and consolidated account of Korean species of Alternaria, which includes 11 species; viz., Alternaria brassicae, A. brassicicola, A. cinerariae, A. dauci, A. dianthi, A. dianthicola, A. helianthi, A. helianthinffciens, A. iridicola, A. japonica and A. protenta. Detailed diagnostic descriptions, specific characterizations, taxonomic discussions and illustrations for each species are presented.

INTRODUCTION: There has been an increasing interest in the relationship between sleep and suicidality. In addition, suicidal patients habitually report their sleep problems. Although sleep-related complaints and electroencephalographic changes are generally encountered in psychiatric disorders, sleep complaints such as insomnia, hypersomnia and nightmares are more common in suicidal patients. In current study, we aimed at investigating the relationship between self-reported sleep duration and suicidality in general population. METHODS: One thousand general population (male : female=500 : 500, mean age=39.6+/-11.6 years, ranged age=20-77 years) completed Center for Epidemiologic Study-Depression (CES-D), Beck Suicide Intent scale (BSI), Spielberger State-Trait Anger Expression Inventory (STAXI), Barratt Impulsiveness Scale (BIS), Morningness-Eveningness Scale (MES) and brief questionnaire of sleep habits. RESULTS: After controlling for age and sex, score of BSI was correlated positively with the score of CES-D, STAXI and BIS on partial correlation analysis (r(p)=0.251 ; p<0.001, r(p)=0.352 ; p<0.001, and r(p)=0.175 ; p<0.001, respectively). In addition, score of BSI was inversely correlated with the score of MES (r(p)=-0.066; p=0.037). However, score of BSI showed no significant correlation with sleep duration. However, regression analysis revealed that short (<6 hrs) or long (>10 hrs) sleep duration, the family history of psychiatric illness, the score of CES-D, and the score of STAXI predicted higher score of BSI significantly in total subjects (F=17.837, adjusted R2 =0.166 ; p=0.003, p=0.003, p<0.001, and p=0.003, respectively). This model was explained better in depressed subjects with 16 or higher score of CES-D (F=9.920, adjusted R2=0.298). CONCLUSION: Current result suggested that not only short sleep duration (<6 hrs) but also long sleep duration (>10 hrs) might be related to suicidality.

OBJECTIVES: Working at other times than the regular day shift has been reported to be a stressor associated with health consequences and mental disorders as well as disturbance of sleep. In current study, we aimed at investigating the relationship between work schedule, sleep quality and depression among police officers. METHODS: Eleven hundreds and forty five police officers (male:1040, female:105) completed questionnaires of basic socio-demographic data, Pittsburgh Sleep Quality Index (PSQI), Korean Scale of Occupational Stress (KOSS), Impact of Event Scale - Revised (IES-R) and Center for Epidemiologic Study-Depression (CES-D). RESULTS: After controlling for age, sex and educational level, score of CES-D was correlated positively with the score of KOSS, PSQI and IES-R on partial correlation analysis (r=-0.077;p=0.009, r=0.262;p<0.000 and r=0.421, p<0.000, respectively). Logistic regression analysis revealed that female sex, age, the score of KOSS and IES-R and schedule of rotating shift work predicted higher score than 16 score of CES-D significantly in total subjects (p=0.023, p=0.015, p=0.000, p=0.000 and p=0.022, respectively). CONCLUSION: Current result suggested that not only female sex, age, higher occupational stress and impact of event scale but also rotating shift work schedule might be related to depression among police officers.

Journal of the Korean Ophthalmological Society 2022;63(11):928-934
Purpose:
To determine whether the clinical features of intermittent exotropia (IXT) needing muscle surgery were different in the ophthalmologist-detected and non-specialist-detected groups (including parents).
Methods:
Medical records of 218 children (mean age: 5.9 ± 1.4 years) with IXT of ≥ 20 prism diopters (PD) were reviewed retrospectively. The angles of deviation were measured using the prism and alternate cover test and assessed by two ophthalmologists using photographs with a translucent occluder (photographic angle). The IXT subtype, fusional control, stereopsis, suppression, and spherical equivalent (SE) were compared between the ophthalmologist-detected and non-specialist-detected groups.
Results:
Mean 25.8 ± 6.8 PD of distant angle of IXT was first detected by the ophthalmologist in 41 patients (18.8%) and the non-specialists in 177 patients (81.2%). The deviated eye was more myopic in the ophthalmologist-detected than non-specialist- detected group (-0.77 ± 1.59 diopters [D] vs. -0.19 ± 1.48 D, p = 0.03). There were no other differences between the two groups. A comparison of 39 age- and non-dominant eye SE-matched pairs demonstrated that the measured angles for distant and near fixation were smaller in the ophthalmologist-detected than non-specialist-detected group (24.0 ± 6.8 PD vs. 28.5 ± 6.4 PD and 26.9 ± 6.6 PD vs. 31.0 ± 6.4 PD, respectively, p < 0.01), while the remaining characteristics, including the photographic angle, were similar.
Conclusions
In cases with small angles of deviation or myopia, IXT with angles requiring surgical correction were commonly first detected by ophthalmologists during examinations.

PURPOSE: To evaluate the differences between IOLMaster(R) and A-scans in changes in axial length after vitrectomy in patients with macular disease. METHODS: Using IOLMaster(R) and A-scans, we measured preoperative and postoperative axial length in 12 eyes with epiretinal membranes (ERM) and in 8 eyes with macular holes (MH). The relationship between the absolute error in axial length after vitrectomy and both methods was assessed using Mann-Whitney U test. The correlation to central macular thickness was evaluated by Spearman's correlation coefficient. RESULTS: In eyes with ERM and MH, preoperative and postoperative axial lengths obtained with both methods had no significant difference (p>0.05). The absolute error in axial length after vitrectomy was not significant using IOLMaster(R) (ERM: 0.07+/-0.05 mm, MH: 0.04+/-0.02 mm, p>0.05) but was significant using A-scan (ERM: 0.20+/-0.11 mm, MH: 0.30+/-0.07 mm, p<0.05). The correlation between the change of axial length after vitrectomy and the central macular thickness was poor (IOLMaster(R): ERM; correlation coefficient = -0.182, p>0.05, MH; correlation coefficient = -0.054, p>0.05, A-scan: ERM; correlation coefficient = -0.210, p>0.05, MH; correlation coefficient = -0.156, p>0.05). CONCLUSIONS: The IOLMaster(R) is more useful than the A-scan when measuring axial length without refractive errors after vitrectomy in eyes with macular disease.

We reviewed a total of 15 cases of heterotopic pancreatic tissue within the gastrointestinal wall(intramural type), and compared with 3 extramural ones. Intramural heterotopic pancreatic lesions were located in the antrum(33%), pylorus(20%), and body of stomach(7%), and the remainders in the duodenum(40%). Only two cases presented with chinical symptoms by their existence. Two of them were situated within the submucosa, 3 in the muscularis, 6 in submucosa-muscularis, 2 in the muscularis-subserosa, and 1 in the susbmucosa-subserosa. Intramural type was featured with their structural heterogeneity compared to the extramural ones; 10 cases showed participation of gastrointestinal mucosal elements, and some accompanied tissue elements that were indistinguishable from submucosal epithelial heterotopia or microduplication cyst of the stomach. Langerhans islets were found in 67%, and one developed islet cell tumor. The above results suggest that the initially engrafted heterotopic pancreatic tissue becomes modified and presents with heterogeneity of endodermal and mesodermal tissue-derived components by its intramural growth during the gastrointestinal organogenesis; failure of opening of its drainage system into the gastrointestinal lumen may result in the increase of intraductal pressure with subsequent atrophy of the acinar tissue and various metaplastic changes of ductal epithelium, aside from induction of smooth muscle coat around the heterotopic tissue.
