  • Since a protein displays its specific functions when disorder region of protein sequence transits to order region with provoking a biological reaction, the separation of disorder region and order region from the sequence data is urgently necessary for predicting three dimensional structure and characteristics of the protein. To classify the disorder and order region efficiently, this paper proposes a classification/prediction method using sequence data while acquiring a non-biased result on a specific characteristics of protein and improving the classification speed. The emerging patterns based EPs-TFP methods utilizes only the essential emerging pattern in which the redundant emerging patterns are removed. This classification method finds the sequence patterns of disorder region, such sequence patterns are frequently shown in disorder region but relatively not frequently in the order region. We expand P-tree and T-tree conceptualized TFP method into a classification/prediction method in order to improve the performance of the proposed algorithm. We used Disprot 4.9 and CASP 7 data to evaluate EPs-TFP technique, the results of order/disorder classification show sensitivity 73.6, specificity 69.51 and accuracy 74.2.

  • The number of people who are suffering from chronic sleep disorder has been growing dramatically in modern era. In order to diagonse the sleep disorder, sleep doctors perform polysomnography: Patients sleep with attaching several vital sign sensors on their body, and doctors monitor the patients in order to find the exact reason of the sleep disorder. Typical polysmonography makes patients sleep with several sensors on their bodies, which prevents the patients from making a comfortable sleep. Furthermore, it is impossible to have a long-term monitoring since the measurements should be done in sleep hosiptal within a few hours. In order to tackle these problems in the typical polysomnography, we envision the development of a non-contact long-term home polysomnography system using UWB radar and related technologies such as multi-modal signal processing.

  • This study was to set the guidelines of soil chemical components in order to assure the safety and quality of the panax ginseng from physiological disorder. The disorder symptoms appeared on the leaf with yellow spot, atrophy, yellow-brown spot, also showed red skin and rough skin of the root. Occurrence type of physiological disorder in cultivated field divided into two types : type I 'such as, yellow spot' consist of single disorder symptom; type II 'such as, yellow spot and yellow-brown spot' consist of two or more different disorder symptoms. The individual contribution of soil properties to the occurrence type was as follows ; The yellow spot was affected by Na > $NO_3$-N > salinity (EC) in soil. The same results was observed in red skin. Atrophy was affected by $NO_3$-N > salinity (EC) > Ca > Mg. Rough skin was affected by $P_2O_5$>pH>Organic material > K. It showed positive associated to $P_2O_5$, pH and K, but negative associated to organic matter. Simultaneous occurrence of two different disorder, including cases which yellow spot and yellow-brown spot, those were affected by $NO_3$-N > salinity (EC) > Na > Mg. In the case of atrophy plus yellow-brown spot, those also were affected by in the order : $NO_3$-N > salinity (EC) > Ca > Mg > Na. Red-rough skin was affected in the order : salinity (EC) > $NO_3$-N > K > Na. Soil chemical components appear to be related to occurrence of physiological disorder, particularly in salinity (EC) and $NO_3$-N. The salinity (EC) and $NO_3$-N were negative related to plant growth. In addition, exchangeable cation capacity play critical roles in attributing to complex occurrence of physiological disorder.

  • Block copolymer (BCP) self-assembly in a film geometry has recently been the focus of increased research interest due to their potential use as templates and scaffolds for the fabrication of nanostructured materials. The phase behavior in a thin film geometry that confines polymer chains to the interfaces will be influenced by the interfacial interactions at substrate/polymer and polymer/air and the commensurability between the equilibrium period (L0) of the BCP and the total film thickness. We investigated the phase transitions for the films of block copolymers (BCPs) on the modified surface, like the order-to-disorder transition (ODT) by in-situ grazing incidence small angle x-ray scattering (GISAXS) and transmission electron microscopy (TEM). The selective interactions on the surface by a PS-grafted substrate provide the preferential interactions with the PS component of the block, while a random copolymer (PS-r-PMMA) grafted substrate do the balanced interfacial interactions on the surface. The thickness dependence of order-to-disorder behavior for BCP films will be discussed in terms of the surface interactions.

  • Cu3AU(100) 단결정은 fcc 구조를 가지고 있으며 (100)면은 Cu와 Au가 1:1로 존재하고 가운데(200)면은 Cu만 존재한다. 따라서 Au 층은 (100)면에서만 존재하여 각 Au층은 서로 0.5nm 떨어져 있다. 이와 같은 Cu3Au(100) 단결정을 MEIS(Medium Energy Ion Scattering Spectroscopy) 실험 장비를 사용하여 0.35nm 떨어져 있는 Single unit cell의 윗면과 아래면, 즉 첫 층의 Au와 셋째층의 Au의 층분리를 통해서, 온도 변화에 따른 Cu3Au(100) 단결정의 표면 물리적 현상인 surface induced disorder을 밝혀내고자 한다. 우선 두 Au층의 분리 시도는 수소이온을 이용한 실험 조건에서는 extremely glancing exit angle 등 극한의 산란조거에서도 성공하지 못하였다. 깊이 분해능을 정해주는 electronic energy loss를 극대화하기 위해 수소이온이 아닌 질소 이온을 사용하여 energy spectra를 측정해 본 결과 아래 그림에서와 같이 표면 Au 층과 표면 셋째 Au층을 구분할 수 있었다. <110>으로 align된 조건에서는 셋째층의 Au 원자들이 완전히 shadow cone 내부에 존재하여 관측되지 않지만 9.75$^{\circ}$ tilt 한 경우 셋째층의 Au 원자들이 shadow cone 바깥으로 나오게 되어 그림에서와 같이 첫째 층과 셋째 층이 확실히 분리되어 측정되었다. 이를 바탕을 Cu3Au(100)의 온도변화에 다른 order disorder and segregation 현상을 측정하였다. ordered Cu3Au(100)은 28$0^{\circ}C$ 근처에서 surface층이 먼저 disordered상으로 바뀌는 surface induced disorder 현상이 일어나고 bulk transition 온도 39$0^{\circ}C$ 이하에서 R.T으로 온도를 낮추면 본래의 ordered 구조로 되돌아간다. 하지만 bulk transition 온도를 지나면 order-disorder transition이 비가역적이고 segregation 현상이 일어난다.
