Replantation after crush amputation has a relatively low success rate. Thrombus formation due to vessel and tissue trauma is considered as the principal cause of failure. In the laboratory and clinically, we have been tried to improve the post-anastomosis patency rate in crushed microvasculature. To accomplish this, we have usually used several anticoagulant drugs. Extracts from the leaves of Ginkgo biloba (EGb) have been used therapeutically for centuries. EGb exerts a number of pharmacologic actions. Eighty rats were control group and another 80 rats were treated with EGb 761. The femoral arteries underwent crush injury with an energy of 0.4J, and the vessles in each group were divided and anastomosed by a standard microsurgical technique. Each group was comprised as follows: ① control group(A1,A2): group A1(n=40); intraluminal saline irrigation, group A2(n=40); intraluminal saline irrigation+heparin 40 u/ml(IV) ② EGb 761 treated group(B1, B2): groupB1(n=40); intraluminal saline irrigation, group B2(n=40); intraluminal saline irrigation + heparin 40 u/ml(IV). At postoperative 14 days, the patency rates were; group A1 20%, group A2 77.5%, group B1 47.5%, group B2 92.5%. These results were interpreted as follows: the patency rate was significantly increased in the EGb 761-only treated group(p<0.01), the heparin-only treated group(p<0.01), and the EGb 761 and heparin-combined at crushed microvessel surgery. However the patency rate of the EGb-only treated group was significantly lower than that of the heparin-only treated group(p<0.01). And in the EGb 761 and heparin-combined treated group compared to the heparin-only treated group, there was some patency rate increase in the combined treated group, but there was no significant difference between them(p=0.060).

Is the “ghost surgery” the subject of legal punishment in Korea?

Seung Eun Hong,Min Ki Hong,Bo Young Park,Kyong Jae Woo,So Ra Kang 대한외과학회 2018 Annals of Surgical Treatment and Research(ASRT) Vol.94 No.4

Purpose: Recently a controversy has arisen about so-called “ghost surgery” practices, and people have voiced their opinions for legal sanction against such practices, which clearly undermine the foundation of medical ethics. However, there has been a lack of legal basis for punishing those actions. The present study aims to examine which pre-existing legal provisions could be applied to regulate ghost surgery. Methods: The Korean Medical Service Act has a provision relating to informed consent to inhibit ghost surgery but does not include penalty provisions prohibiting ghost surgery itself. Also, the Korean Supreme Court precedents on this issue have not been settled as of yet. Therefore, this study referred to U.S precedents, law books, and related papers. Results: With respect to ghost surgery, we expect the charges of bodily harm, assault and battery, and fraud could be applied under Korean law, in addition to charges regarding the violation of medical law, such as the omission of entries or false entries in medical records. A patient provides consent to bodily harm prior to surgery, and only the person who is entrusted with such permission can become the operating surgeon in the operating room. Conclusion: In other words, even if other medical professionals are present in the operating room, the operating surgeon who received consent must take overall responsibility for the whole process of the surgery. A surgeon should bear in mind that a violation of such duty can constitute a criminal offense.

임신과 연관된 유방삽입물 주의 피막 구형 구축의 변화에 대한 임상적 연구

It has been reported that the frequency of the development of peripheral capsuler contracture after breast augmentation surgery using silicone-gel implants amounts between 25 to 50%. Various treatments to cure or prevent the capsular contracture are mow being studied and introduced, including submuscular insertion of breast implants, steroid instillation, oral intake of Vit-E, postoperative breast massage, regional injection of antibiotics, and a saline-filled implantation without gel-bleed. This paper reports, along with the literal study, on the improvement of the softening of capsular contracture condition observed from 12 patients who have undergone pregnancy and delivery after breast augmentation surgery operated at the Plastic surgery departments of Ewha University Medical Center and Seoul National University Medical Center during 1985-1995. Conceivably, the softening of the capsular contracture is attributable to the hormonal change, immunologic and inflammatory alteration, and the masking effect resulting from mammary alveolar hypertrophy. It is believed that a study should be continued on the relationship between the pregnancy and the softening of capsular contracture condition.

The structural, morphological, and optical properties of zinc sulfide (ZnS) thin films deposited using chemical bath deposition method are reported. These films were deposited on soda lime glass substrates using Na2EDTA as a complexing agent, in acidic medium at 80 ℃. The effect of the pH ranging from 5 to 6.5 on quality of ZnS thin films is investigated. Irrespective of the pH values used for the deposition all films are polycrystalline with a wurtzite (hexagonal) structure. Field emission scanning electron microscopy (FE-SEM) characterization shows that the surface of the sample deposited with pH 5 and 5.5 is compact and uniform. However, agglomerated clusters (~100 nm) are observed in ZnS thin films grown with pH above 6. X-ray photoelectron spectroscopy results shows the presence of only Zn–S bonding for the ZnS thin film grown at pH = 5 while those films deposited with pH > 5.5, Zn–OH as well as Zn–S bonding have been observed. The composition is almost stoichiometric for a wide range of pH values of the solution (5–6.5). The transmission spectrum of ZnS thin films having thickness from 30 to 220 nm indicates a good transmission characteristic with an average transmittance of 70–85%. The absorption coefficient depends on the pH values of the solution used and are responsible to the changes observed in absorption edges. The band gap energy values of ZnS thin films decreased from 3.91 to 3.78 eV with increasing pH values of the solution.

So Ra Kang,Shin-Jeong Kim,Kyung-Ah Kang 한국아동간호학회 2023 Child Health Nursing Research Vol.29 No.4

Purpose: Artificial intelligence (AI) has had a profound impact on humanity; in particular, chatbots have been designed for interactivity and applied to many aspects of daily life. Chatbots are also regarded as an innovative modality in nursing education. This study aimed to identify nursing students' awareness of using chatbots and factors influencing their usage intention. Methods: This study, which employed a descriptive design using a self-reported questionnaire, was conducted at three university nursing schools located in Seoul, South Korea. The participants were 289 junior and senior nursing students. Data were collected using self-reported questionnaires, both online via a Naver Form and offline. Results: The total mean score of awareness of using chatbots was 3.49±0.61 points out of 5. The mean scores of the four dimensions of awareness of using chatbots were 3.37±0.60 for perceived value, 3.66±0.73 for perceived usefulness, 3.83±0.73 for perceived ease of use, and 3.36±0.87 for intention to use. Significant differences were observed in awareness of using chatbots according to satisfaction with nursing (p<.001), effectiveness of using various methods for nursing education (p<.001), and interest in chatbots (p<.001). The correlations among the four dimensions ranged from .52 to .80. In a hierarchical regression analysis, perceived value (β=.45) accounted for 60.2% of variance in intention to use. Conclusion: The results suggest that chatbots have the potential to be used in nursing education. Further research is needed to clarify the effectiveness of using chatbots in nursing education.

So Ra Park,Choong Hwan Kwak,Young Ran Kang,Myung Ki Seo,Min Kyung Kang,Jung Hyun Cho,Yeon Jeong Ahn,Jin Yong Hwang 연세대학교의과대학 2009 Yonsei medical journal Vol.50 No.1

We report a 55-year-old female patient who presented with no P waves but with a wide QRS complex escape rhythm at 44 beats/min and prolonged QTc of 0.55 seconds on ECG. The patient had recurrence of ventricular fibrillations and loss of consciousness, and underwent defibrillation and cardiopulmonary resuscitation (CPR) several times because of cardiac arrest. The transthoracic echocardiography showed dilated cardiomyopathy and enlargement of both atria. The Doppler echocardiography documented the absence of A wave in the tricuspid and mitral valve flow. An electrophysiologic study demonstrated electrical inactivity in the right and left atria. Atrial pacing with maximum output did not capture the atria. These findings together with her electrocardiographic finding indicated atrial standstill. Sudden cardiac death was her first clinical manifestation of ventricular arrhythmia. The patient remained asymptomatic after receiving a single chamber implantable cardioverter-defibrillator (ICD) with VVI pacemaker function.

Consideration of Discrepancy between Needle-Washout Thyroglobulin and Serum Thyroglobulin of Recurrent Papillary Thyroid Cancer

So Ra Kim,Mi-Kyung Kwak,Hye Ran Kang,Seug Yun Yoon,Seong Soon Kwon,Bo Young Kim,Hoo Nam Choi,Hye Jeong Kim,Jae Wook Kim,So-Young Jin,Hyeong Kyu Park,Dong Won Byun,Kyoil Suh,Myung-Hi Yoo 순천향대학교 순천향의학연구소 2014 Journal of Soonchunhyang Medical Science Vol.20 No.2

Although the prognosis of papillary thyroid cancer (PTC) is extremely good, locoregional recurrences after initial treatment occur. Thyroglobulin (Tg) is a reliable tumor marker to detect recurrence or persistence of PTC. However, occasionally serum Tg may miss the detection of a recurrence. We report a 54-year-old female presented with hoarseness due to cervical recurrence without concomitant elevation of serum Tg and anti-Tg antibody, in contrast to extremely increased needle-washout Tg, who had undergone a total thyroidectomy and radioiodine ablation as initial therapies for PTC. Several factors causing such discrepancy between needlewashout Tg and serum Tg can be suggested including site of recurrence, volume of tumor, interference by some kind of plasma antibodies other than anti-Tg antibody, and any conformational defect of Tg protein. Among them, the most convincing explanation is that any conformational defect of Tg may lead to impaired secretion of Tg to blood. We suggest that more studies are needed to find the cause for potential mechanisms involved in PTC recurrences without increased serum Tg.

Development of a Violence Prevention Educational Program for Elementary School Children Using Empathy (VPEP-E)

So Ra Kang,김신정,Jungmin Lee 한국아동간호학회 2020 Child Health Nursing Research Vol.26 No.4

Purpose: This study describes the development of a violence prevention educational program for elementary school children using empathy (VPEP-E) that teachers can use during class. Methods: Hoffman's theory of empathy and Seels and Richey's (1994) ADDIE model were applied to develop this program. Results: The developed program consisted of eight sessions: "Orientation/ definition of violence and empathy", "Types and boundaries of violence", "Look into my feelings", "Say it with a facial expression", "Preventing non-empathic violence due to social prejudice", "Preventing physical violence", "Verbal and online violence prevention: empathic conversation", and "I can do well: review of the whole curriculum". The program was evaluated by 15 elementary school teachers, who considered it to be easily accessible to elementary school students. The final VPEP-E, which will be provided in eight times for 40 minutes each for fifth-grade students, will provide a basis for preventing violence by fostering empathy. Conclusion: We expect the developed educational program to be effective in preventing violence among elementary school students. However, further research involving children from various age groups is needed.
