The computed tomography (CT) number is closely related to hematocrit level according to many of the previous reports. We measured the CT number in various organs, such as the frontal white matter, basal ganglia, occipital white matter, cerebrospinal fluid, liver, abdominal aorta, spleen, kidney, and psoas muscle. We correlated the CT numbers of the organs with hematocrit levels which were graded into 10% increments (20.0-29.9%, 30.0-39.9%, 40.0-49.9%). Thus the change of CT numbers in various organs according to the hematocrit level was analyzed. The increased CT numbers according to the 10% increment of hematocrit in the frontal white matter, basal ganglia, occipital white matter, liver, abdominal aorta, spleen, and psoas muscle were 1.3, 1.5, 1.6, 3.3, 5.3, 3.8, 2.4 respectively. Even though the CT numbers of the cerebrospinal fluid and kidney were not influenced by hematocrit level the CT numbers in most of the there organs postitively correlated with hematocrit level. Therefore, it was concluded that in the differential diagnosis using CT numbers, the hematocrit level of patient must be taken into consideration.

The authors evaluated the clinical significance of the bilirubin values as screening test means for predicting the occurrence of neonatal jaundice earlier after birth, by using the transcutaneous bilirubinometry which is known to measure the bilirubin values in a noninvasive, accurate and simple way. The results obtained were as follows: 1. In comparison between the test group(showing the symptom of a jaundice within 72 hours after birth) and the control group, there were found no statistically significant differences in terms of sex, delivery type, birth weight, gestational age and mother's age, while being found statistically significant differences in terms of transcutaneous bilirubin at birth(TcBbirth), transcutaneous bilirubin at 24 hours after birth(TcB24hr), increase in transcutaneous bilirubin per hour during the first 24 hours after birth(TcBin/hr) and transcutaneous bilirubin at 72 hours after birth(TcB72hr)(p<0,05). 2. The correlation test using the Pearson's coefficient produced statistically significant correlationship between each transcutaneous bilirubin index (TcBbirth, TcB24hr, TcBin/hr and TcB72hr) and serum bilirubin concentration at 72 hours after birth(B72hr)(p<0.05), while the result of the correlation test using the Spearman's roh showed statistically significant correlationship only between TcB24hr or TcB72hr and B72hr(p<0.05). As it was, the correlationship between TcB72hr and B72hr was highest in both Pearsons coefficient and Spearman's roh tests, followed by that between TcB24hr and B72hr. 3. In view of the ROC graph, the most effective means of predicting the occurrence of the neonatal jaundice was TcB72hr followed by TcB24hr, TcBbirth and TcBin/hr in their order. In particular, TcB24hr was conceived to be useful as screening test for determining an early discharge from the nursery within 48 hours. On the other hand, since the negative predictive value of TcBbirth, and TcB24hr is higher, the possibility that those infants showing a lower value of these indices may well be free later from a serious neonatal jaundice even if they should be discharged earlier from the nursery. In conclusion, those four indices predicting the neonatal jaundice in a simple, quick and noninvasive manner using the transcutaneous bilirubinometry were considered to be effective screening test means whereby any serious neonatal jaundice developed earlier after delivery can be successfully predicted.

4.Criminal liability of medical professionals.
Journal of the Korean Medical Association 2013;56(8):655-664
The Medical Service Act and many other laws regulate the actions of medical professionals. Receiving rebates from pharmaceutical companies has been criticized as unethical but not punished until 2011. However, it is now strongly forbidden. Unlicensed acts of medical care, which include providing medical care beyond the scope of the license or giving directions to an unlicensed person to practice medical care, are strictly punished even in the case of licensed medical professionals. It recently became an issue whether a doctor who wrote prescriptions to patients after examining them over the telephone violated the Medical Service Act. In addition, it is necessary to pay special attention to the administration of propofol since it recently became a major controversy. Furthermore, public health doctors are legally forbidden to work outside of a public health institution. The number of regulations on the medical industry is increasing every day. New laws usually toughen up punishment for those violating regulations. There is a legal maxim that says, "Ignorance of law excuses no one." Therefore, it is necessary for medical professionals to steadily study and become familiar with applicable laws and related criminal cases to prevent themselves from becoming criminally liable.

The estimation of age is an important issue in forensic science, and the forensic community has attempted many times to establish methods for solving this issue. Aging leads to alterations in tissues and organs at the molecular level. These alterations at the molecular level may aid forensic scientists to estimate the age of a living person or a dead body. Initially, the focus was on the genetic components of aging, but recently, epigenetic mechanisms have emerged as the key contributors to the alterations in genome structure and function that accompany aging. In particular, DNA methylation is one of the best-understood mechanisms, and it has been suggested as a promising biomarker for age estimation in many studies. In this review, we summarize the recent studies on age-associated DNA methylation changes in different tissues and discuss its possible and practical applications in forensics.

The treatment of gonorrhea caused by beta-strains of N. gonorrhoeae is quite different from that of non-beta-strains, but it is not always possible in general practice to take cultures of gonococci to detect p-lactamase producing organisms. Therefore treatment regimens commonly used for gonorrhoea should be effective against both PPNG non-PPNG strains. Eighty-seven male uncomplicated gonorrheal patients were treated with intramuscular kanarnycin 2gm in combilnation with talampicillin 2. 5 gm plus probenecid 1grn orally. Sixty-seven patients were followed up. All patients recovered. Ten patients among sixty-seven patients had PPNG. A regimen of intramuscular kanamycin 2 gm, talampicillin 2. 5 gm plus probenecid 1 0 gm orally seems to be one of the most cost effective regimens in Korea.

10.Clinical Comparison between Glaucoma Triple Procedure and Small Incision Cataract Surgery using Foldable silicone IOL.
Journal of the Korean Ophthalmological Society 1999;40(3):810-818
The purpose of this study was to evaluate the postoperative outcomes between the glaucoma triple procedure and the small incision cataract surgery using foldable silicone intraocular lens(IOL). This prospective randomized study comprised of 42 eyes which had the glaucoma triple procedure and 41 eyes which underwent small incision cataract surgery at chonnam University Hospital from May, 1994 to December, 1996. At least 3 months follow-up period was needed. Corrected visual acuity of 0.5 of better was obtained in 50% of triple procedure group and 88% of small incision cataract surgery group with the average lines of improved visual acuity of 5.6 and 7.2 respectively. There was no significant change in the refractive cylinder during the early postoperative period in both group. In the glaucoma triple procedure group, posterior capsular opacification(PCO) developed in significantly low incidence in the Mitomycin C using group and the incidence of PCO in eyes with IOL decentration was greater than in those without IOL decentration. In conclusion, patients who underwent glaucoma triple procedure using foldable silicone IOL showed excellent postoperative IOP control with success rate of 81%, rapid visual rehabilitation and refractive stability. We also found that glaucoma triple procedure with Mitomycin C was associated with lower incidence of PCO.
