Semi-empirical multi-port lattice model for long-period fiber grating analysis under arbitrary temperature distributions

Jun Kye Bae, Namkyoo Park, Jinho Bae, Dongyeon Koh, Sang Hyuck Kim, Sang Bae Lee
2008 Optics Express  
We propose a semi-empirical model for the complete analysis (spectrum, bandwidth, and wavelength / phase shifts) of a temperaturetuned long-period fiber grating (LPFG) filter. By applying the multi-port lattice model to LPFGs, while deriving and utilizing the empirically determined temperature-dependence of core-to-cladding intermodal dispersions, we achieve a precise, practical means of spectrum analysis. Excellent agreement of the model with the experimental results was obtained over wide spectral ranges.

Transumbilical Retroperitoneal Lumbar Interbody Fusion: A Technical Note and Preliminary Case Series

Junseok Bae, Shin-Jae Kim, Sang-Ho Lee, Youngsik Bae, Sang Hyeop Jeon
2021 Neurospine  
Objective: Anterior lumbar interbody fusion (ALIF) has advantages over posterior lumbar interbody fusion or transforaminal lumbar interbody fusion techniques in that it minimizes damage to the anatomical structure of the posterior spinal segment and enables indirect decompression of the foramen by insertion of a tall cage. However, the predominant abdominal scar tissue reduces patients' satisfaction after ALIF. Herein, we describe the technique of transumbilical lumbar interbody fusion (TULIF)

After preoperatively selecting patients by evaluating the location of the umbilicus and vessel anatomy, a vertical skin incision was made on the umbilicus to minimize the abdominal scar tissue. Results: There were 120 single-level (110 L4-5 and 10 L3-4), 31 two-level, and 3 three-level surgeries. All patients were very satisfied with their postoperative abdominal scars, which were noticeably faint compared to those after conventional ALIF. Conclusion: TULIF is a feasible, minimally invasive surgical option that can achieve both the treatment of degenerative spinal disease and satisfactory cosmesis. Although it is technically demanding, patients obtain sufficient benefits.

We propose an analysis technique of thermally tunable LPFG Filter with multiple cladding mode using multiport lattice filter model. Using LPFG with different cladding modes, we could verify the validity of the proposed model experimentally.

Minimum-Width Double-Strip and Parallelogram Annulus [article]

Sang Won Bae
2019 arXiv   pre-print
In this paper, we study the problem of computing a minimum-width double-strip or parallelogram annulus that encloses a given set of n points in the plane. A double-strip is a closed region in the plane whose boundary consists of four parallel lines and a parallelogram annulus is a closed region between two edge-parallel parallelograms. We present several first algorithms for these problems. Among them are O(n^2) and O(n^3 log n)-time algorithms that compute a minimum-width double-strip and

Antioxidant therapy of type 2 diabetic peripheral neuropathy

Hyun Bae Park, Ji Sung Kim, Sang-Bae Han
2018 Yakhak Hoeji  
Diabetic peripheral neuropathy (DPN) is a nerve damage caused by chronically high blood glucose and diabetes. It leads to loss of sensation and sometimes pain in feet, legs and hands. More than 50% of type 2 diabetic patients will develop this complication. To date, the pathogenesis of DPN remains unclear. However, hyperglycemia, metabolic imbalance, and oxidative stress appear in the neurons of DPN patients. In addition, oxidative stress results in the change of poly-ADP-ribose polymerase,

According to the oxidative stress and related pathways of DPN, some drugs are used in clinical treatment, such as taurine, acetyl-L-carnitine, aldose reductase inhibitors (epalrestat, ranirestat), α-lipoic acid (ALA), protein kinase C inhibitor (ruboxistaurin), inhibitor of poly ADPribose polymerase (nicotinamide), angiotensin-converting enzyme inhibitor (trandolapril), and advanced glycation end product inhibitors (aspirin, benfotiamine). However, no drugs can completely cure it. In this review, we summarize the pathogenesis of DPN and suggest that amifostine, which is clinically used as an antioxidant, might be used for the treatment of DPN. 2형 당뇨환자의 당뇨병성 말초신경병증(Diabetic peripheral neuropathy, DPN) 유병율은 50%이상인 것으로 보고되었다. 1-5) 국내 당뇨병성 신경병증 진료지침에 의하면 당뇨병성 신경병증 (diabetic neuropathy)은 해부학적 구조나 병리기전보다는 임상 양상의 관점에서 분류한다. 6) 임상에서 가장 흔히 접하는 DPN은 만성 감각운동신경병증에 속한다. DPN은 50%까지 무증상일 수 있으나 말초신경병성 통증(Diabetic peripheral neuropathic pain) 이나 자율신경병증을 동반하기도 하며 진행되면 궤양, 샤르코 관 절, 절단의 위험이 증가한다. 6) 당뇨병성 자율신경병증(diabetic autonomic neuropathy)은 중년 이상이거나 오래된 제1형 당뇨병 환자에서 흔하며 완치가 어렵고 삶의 질을 크게 떨어뜨린다. 6) 그 중 심혈관계 자율신경병증(cardiovascular autonomic neuropathy) 은 사망률과도 연관되어 특히 주의를 요한다. 6) DPN 진행 초기 에는 말초신경의 small nerve fiber 소실이 일어나게 되고, 일부 환자들은 무해자극 통증을 느끼게 된다. 유병기간이 길어짐에 따 라 large nerve fiber가 손상되면서, 당뇨환자들은 손발이 저리거 나 무감각해지며 궁극적으로는 사지근육의 마비가 나타난다. 4) 미 국 당뇨병학회(ameriacan diabetes association, ADA)의 DPN에 대한 약물치료 가이드라인은 손발 저림이나 신경통증을 줄여주 기 위한 대증요법적인 접근을 하고 있다. Pregabalin이나 serotonin norepinephrine reuptake inhibitor (SNRI)가 DPN의 1차 처방약이지만 당뇨병성 말초신경병증을 치료하거나, 그 진행 을 늦추지는 못한다. 4, 7)
