Liquid‐Crystalline Blue Phase Laser with Widely Tunable Wavelength (Adv. Mater. 21/2013)
Hur, Sung‐,Taek,Lee, Bo Ram,Gim, Min‐,Jun,Park, Kyung‐,Won,Song, Myoung Hoon,Choi, Suk‐,Won WILEY‐VCH Verlag 2013 ADVANCED MATERIALS Vol.25 No.21
<P>A liquid‐crystalline blue‐phase laser with a tunable photonic bandgap (PBG) of over 150 nm and a wide temperature range is demonstrated by Myoung Hoon Song and Suk‐Won Choi on p. 3002. A lasing peak shift of more than 100 nm is realized due to the large PBG shift of the liquid‐crystalline blue phase. The shift in the lasing wavelength was reversible during repeated temperature changes over the entire stability range of the liquid‐crystalline cubic blue phase. </P>

Background Implant-based breast reconstruction is being performed more frequently, and implants are associated with an increased risk of infection. We reviewed the clinical features of cases of implant infection and investigated the risk factors for breast device salvage failure. Methods We retrospectively analyzed 771 patients who underwent implant-based breast reconstruction between January 2010 and December 2016. Age, body mass index, chemotherapy history, radiation exposure, and smoking history were assessed as potential risk factors for postoperative infection. We also evaluated the presence and onset of infection symptoms, wound culture pathogens, and other complications, including seroma, hematoma, and mastectomy skin necrosis. Additionally, we examined the mastectomy type, the use of acellular dermal matrix, the presence of an underlying disease such as hypertension or diabetes, and axillary node dissection. Results The total infection rate was 4.99% (58 of 1,163 cases) and the total salvage rate was 58.6% (34 of 58). The postoperative duration to closed suction drain removal was significantly different between the cellulitis and implant removal groups. Staphylococcus aureus infection was most frequently found, with methicillin resistance in 37.5% of the cases of explantation. Explantation after infection was performed more often in patients who had undergone 2-stage expander/implant reconstruction than in those who had undergone direct-to-implant reconstruction. Conclusions Preventing infection is essential in implant-based breast reconstruction. The high salvage rate argues against early implant removal. However, when infection is due to methicillin-resistant S. aureus and the patient's clinical symptoms do not improve, surgeons should consider implant removal.
Allelic Deletions of Chromosomes in Human Colorectal Cancer Development
Song, Young Tack,Kim, Seung Nam,Lee, Jai Hak,Yoo, Seung Jin,Cho, Won Il,Chang, Suk Kyun,Choo, Sang Yong CATHOLIC MEDICAL CENTER 1993 Bulletin of the Clinical Research Institute Vol.21 No.2
Two types of genetic alterations have been reported in colorectal tumors. The first type involves point mutations in ras proto-oncogenes. The second type of alterations involves detection of specific chromosomal regions. Deletions can be detected by restriction fragment length polymorphism analyisis of tumor DNA. The deleted sequences have been hypothesized to include tumor suppressor gene. The inactivation of tumor-suppressor gene by deletion of suspected locus lead to neoplatic growth. To investigate the relation between ras point mutation and allelic deletion of chromosome 17p and 18q, both p-PCR and RELP analysis using VNTR marker and synthetic oligonulectide probe tailing with digoxigenin Ⅱ-dUTP were done in 15 normal mucosa and 22 colorectal cancer mucosa. The obtained results were as follows: 1. Incidence of ras point mutations was 80% (4/5) in Dukes’ B, 82.3% (14/17) in Dukes’ C. There was increasing tendency of mutation along with stage progression, but no statistical significance was noted. 2. Incidence of ras point mutations were 45.4% (5/11) in well differentiated cancer and 77.7% (7/9) in moderately differentinted cancer. 3. Incidence of allelic diletion of 17p pYNH37 were 80% (5/11) in Dukes’ B, 64,7% (l1/17) in Dukes’ C. There was no correlation of incidences of 18q OS-4 in colorectal cancer. But incidence of 17p allelic deletion was higher than 18q allelic deletion in Dukes’ C colorectal cancer. The allelic deletions of pYNZ22 were noted in 6 cases of Dukes’ C colorectal cancer but not in Dukes’ B colorectal cancer. 4. There was no statistical difference between incidence of ras point mutation and allelic deletion in colorectal cancer. These results showed there was no statistical difference in incidence of ras point mutation & 18q allelic deletion in colorectal cancer. 17p allelic deletion occurred more frequently in advanced colorectal cancer. Genetic alteration did not have any correlation with cellular differentiation or tumor location in the biologic behavior of the colorectal cancer.

Peanut is grown worldwide in the tropics and temperate zones primarily as an oilseed crop (38-54%) and protein source(25-30%). A new peanut variety “Daan”(Arachis hypogaea ssp. fastigiata L.) with the high yield potential was developed at the Department of Southern Area Crop Science, NICS, in Milyang in 2014. This was developed from the crossing line between cultivar “Sangpyeong” with short stem and high quality and “Dakwang” with large grain. “Daan” which is Shinpung plant type has 44cm of main stem length and 13 branch number per plant. Each pod has two grains with long ellipse shape of brown testa and yield components is composed of 34 mature pods of per plant, 127g of 100-seed weight, 75% of pod shelling ratio in the regional yield trials(RYT). Seed quality showed 47.8% of crude oil and 28.3% of protein content. This variety also showed more resistant to early leaf spot, late leaf spot, web blotch, stem rot and lodging compared with check variety “Daekwang”. In the regional yield trials “Daan” outyielded check variety by 16% with 5.00 MT/ha for kernel yield.

Song Joon Young,Cheong Hee Jin,Kim Sung Ran,Lee Sung Eun,Kim Su Hyun,Noh Ji Yun,Yoon Young Kyung,Choi Won Suk,Park Dae Won,Sohn Jang Wook,Kim Woo Joo,Kim Min Ja 대한의학회 2021 Journal of Korean medical science Vol.36 No.15
Hospital-based surveillance for adverse events was conducted on healthcare workers after they received the first dose of coronavirus disease 2019 (COVID-19) vaccine. Among the two new platform vaccines (messenger RNA- and adenoviral vector-based vaccines), the rates of systemic adverse events were significantly higher among adenovirus-vectored vaccine recipients. Fatigue (87.6% vs. 53.8%), myalgia (80.8% vs. 50.0%), headache (72.0% vs. 28.8%), and fever (≥ 38.0°C, 38.7% vs. 0%) were the most common adverse events among adenovirus-vectored vaccine recipients, but most symptoms resolved within 2 days. Both types of COVID-19 vaccines were generally safe, and serious adverse events rarely occurred.

A new peanut(Arachis hypogaea ssp. fastigiata L.) variety “Danwon(Milyang51)” with short stem length and lodging resistance was developed at the Department of Functional Crop, NICS, in Miryang in 2013. This variety was developed from the crossing line between cultivar “YG 75” with large grain and fewer branch number and “SP9617” with short stem length. “Danwon” which is Shinpung plant type has 32cm of main stem length and 13 branch number per plant. Each pod has two grains with long ellipse shape of brown testa and yield components is composed of 40 mature pods of per plant, 91g of 100-seed weight, 77% of pod shelling ratio in the regional yield trials(RYT). Seed quality show 48.7% of crude oil and 26.9% of protein content. “Danwon” has resistance to lodging in even double dense planting without yield reduction. This is more resistant to early and late leaf spot, web blotch and stem rot, compared with check variety “Daekwang”. In the regional yield trials “Danwon” outyielded check variety by 6% with 4.52 MT/ha for kernel.
