1.Macrophage/dendritic Cell Marker Staining Characteristics of Langerhans cell Granulomatosis(Histiocytosis X).
Korean Journal of Pathology 1992;26(3):310-313
Histiocytosis X is characterized by aggregates of Langerhans cells with other inflammatory cells. These Langerhans cells are antigen-presenting cells to T lymphocytes and identified by characteristic morphology, ultrastructural demonstration of Birbeck granules and immunologic reactivity with OKT-6 and HLA-DR antibodies. In this report, the tumor arising in a 2-years-old baby was examined byimmunostaining with several macrophage/dendritic cell markers. The main tumor cells showed cytoplasmic and nuclear staining with S-100 protein and ring-like surface and paranuclear staining with PNA. However, they were negative for follicular dendritic cell marker CD21, macrophage markers lysozyme, Mac 387, alpha-1 antitrypsin and CD68, and interdigitating reticulum cell marker ID4 and ID5. These observations demonstrate the usefulness of S-100 protein and PNA for the identification of Langerhans cells in paraffin-embedded tissue.

Congenital hepatic fibrosis is an inherited, congenital disorder of the liver, and is occasionally associated with cystic disease of the liver and kidney. We present a case of congenital hepatic fibrosis with Caroli's disease. A 21-year-old woman had suffered from an episodic fever with headaches for 3 years. In laboratory examination, the liver function test was within the normal limits. Esophageal varix was noted by an endoscopic examination. Hepatosplenomegaly and multiple dilated bile ducts were seen by abdominal CT scanning. An orthotopic whole liver transplantation was done. The liver was fibrotic and enlarged. Multiple cystically dilated intrahepatic ducts were noted. Microscopically, diffuse portal fibrosis and widening with proliferation of bile ductules were seen. Intrahepatic bile ducts were markedly dilated and tortuous. The liver cell cords were well preserved.

5.Factors Influencing Nurses’ Performance of Care in COVID-19 Wards
Journal of Korean Academy of Nursing 2021;51(6):678-688
Purpose:
The purpose of this study was to identify factors influencing nurses’ performance of care in COVID-19 wards.
Methods:
The participants were 132 nurses who worked in COVID-19 wards at three hospitals, and were recruited from April 1 to May 31, 2021. Data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression analysis with SPSS/WIN 24.0 program.
Results:
Nursing performance was significantly and positively correlated with ethical sensitivity (r = .75, p < .001), nursing professionalism (r = .67, p < .001), and social support (r = .67, p < .001). Nursing professionalism was positively correlated with ethical sensitivity (r = .64, p < .001) and social support (r = .55, p < .001). Multiple regression analysis for nursing performance revealed that the most significant factor was ethical sensitivity (β = .47, p < .001). Ethical sensitivity, nursing professionalism, and social support explained 66.0% of total variance in nursing performance.
Conclusion
Ethical sensitiviy, nursing professionalism, and social support significantly influence nurses’ performace of care in COVID-19 wards. It suggests that intervention programs should be directed at improving nurses’ ethical sensitivity, bolstering social support, and enhancing nursing professionalism.

OBJECTIVES: To develop reliable tools for measuring communication skills in schizophrenia, the present study proposed the concept of communication intelligence, consisting of conversational competence, emotional competence, and empathic competence, and explored its neurobiological underpinnings using regional gray matter volume with healthy people. METHODS: Communicative intelligence scores were obtained from 126 healthy young participants. Correlation analyses between regional volume distributions and communication intelligence subcomponents were conducted using voxel-based morphometry of structural MRI. RESULTS: The significant positive correlations between the regional gray matter volumes with conversational competence were found mainly at the ventromedial frontal gyrus while the negative correlations between the bilateral middle frontal gyrus. With emotional competence, the volume of right superior temporal gyrus was positively and that of bilateral insula was negatively correlated. With empathic competence, the volume of the left middle frontal gyrus was positively and that of the insula was negatively correlated. CONCLUSION: Each of the subcomponents of communicative intelligence scores showed distinctive neurobiological underpinnings. The regions for the subcomponents, which constitute a common network for social cognition and emotion, are highly associated with the regions of the schizophrenia pathology. In conclusion, communicative intelligence scales have neurobiological basis to evaluate social skills of patients with schizophrenia.

7.Circumferential Buckling on Equator: II. Advantages of Circumferential Buckling on Equator with Conserved Scleral Implant.
Journal of the Korean Ophthalmological Society 1979;20(3):309-311
As a contrast to the surgery described in part I, a lamellar undermining was performed in a conventional way. The sclera was lamellarly undermined on the retinal hole areas which extended at least 3 mm beyond the disc edge of the retinal breaks. If the scleral buckling with a circling element is indicated the location of the undermined area determines whether the circling band must follow the globe's equator or another great circle around the eye, The technique for decreasing a vitreoretinal traction used in this series of cases was that proposed by Schepens. Of 56 surgical procedures for retinal detachment, there was a case of an unsuccessful closure of the retinal break due to fishmouthing of the posterior edge of the break. The technique proposed by Schepens was sufficiently promising. But it has the following drawbacks; difficulties in exact hole localization in a high detached retina, anchoring sutures of the circling band behind the equator and problems to protect the vortex veins from the circling band etc. Our experience since 1978, led us to modify the conventional view, in favor of the circumferential buckling on the equator.

A fifteen yrs old boy developed divergence paralysis following meningitic attack. The ocular examination revealed homonymous diplopia in all gazes when he fixed at further than 13 cm. He had 18 delta esotropia at distance and 7 delta esophoria at near in prism cover test. His stereopsis was excellent at near in House Fly Stereopsis Test. There wasn't much change in ocular examination in 90 days after initial examination.
