  • The physicochemical properties of sweet potato (SP) starches reclaimed from an SP-processing sludge without freezing (RC/NF) and with freezing (RC/FR) were investigated. Lab-isolated (LI) SP starch, as a control, were prepared from raw SP. RC/NF and RC/FR SP starches were recovered from SP-processing sludges by the repeated sieving and washing procedure. The total starch contents and amylopectin branch-chain distributions did not differ for three SP starches. Relative to LI and RC/NF SP starches (possessing similar physicochemical characteristics), the apparent amylose and phosphorus contents, swelling factor, and pasting viscosity were reduced for RC/FR SP starch. However, the freezing treatment altered X-ray diffraction pattern (at $5.5^{\circ}$, $11-12^{\circ}$, and $24^{\circ}$ $2{\theta}$) of RC/FR SP starch, which likely increased its gelatinization peak and completion temperatures. Its amorphous region in total diffractogram was reduced, resulting in the enhanced relative crystallinity. Overall results suggested SP starches recovered from an SP-processing sludge would have the potential to replace commercial SP starch products.

  • The composite stock cutting problem is to allocate rectangular and/or irregular patterns onto a large composite stock sheet of finite dimensions in such a way that the resulting scrap will be minimized. In this paper, the distributed simulated annealing with the new cost error tolerant spatial decomposition is applied to the composite stock cutting problem in MPI environments. The cost error tolerant scheme relaxes synchronization and chooses small perturbations on states asynchronously in a dynamically changed stream length to keep the convergence property of the sequential annealing. This paper proposes the efficient data structures for representation of patterns and their affinity relations and also shows how to determine move generations, annealing parameters, and a cost function. The spatial decomposition method is addressed in detail. This paper identifies that the final quality is not degraded with almost linear speedup. Composite stock shapes are not constrained to convex polygons or even regular shapes, but the rotations are only allowed to 2 or 4 due to its composite nature.

  • This study was performed to investigate the location of the ideal bracket positioning plane in lingual orthodontics using the three-dimensional finite element method. Displacement of the anterior teeth were evaluated according to the vertical and the angular movements of the bracket positioning plane. To achieve the ideal movement of anterior teeth in the lingual central plane, the location of the force application point and the amount of the moment applied to the four incisors were evaluated. As the bracket positioning plane was moved parallel toward the incisal edge, uncontrolled tipping and extrusion of the maxillary and the mandibular incisors were increased. But lingual tipping of the crown was decreased in the maxillary and the mandibular canines. As the bracket positioning plane was inclined toward the incisal edge, lingual tipping was increased in the 6 anterior teeth and extrusion of incisors and intrusion of the canine was also increased. As the retraction hook of the canine bracket was elongated, lingual tipping and extrusion of the central incisor and mesial movement and extrusion of the lateral incisor were increased. In the canine, mesial and labial movements of the crown were increased. When the moment was applied to the 4 incisors of the maxillary and the mandibular arch in the lingual central plane, 280 gf-mm in the maxillary central incisor, 500 gf-mm in the maxillary lateral incisor, 170 gf-mm in the mandibular central incisor and 370 gf-mm in the mandibular lateral incisor produced bodily movement of the individual tooth.

  • 임상 결과의 측정에서 새로운 관점을 갖는 것은 중요하다. 의료 재활은 심리적 측정의 질들(표준화, 신뢰도, 타당도)에서 충분한 노력에 수행되어지지 않아 왔기 때문에 환자와 프로그램 사이에 일반화된 기능적인 평가 범위가 부족하다. 장애의 적절한 측정을 위한 요구는 기능적인 상태에서 변화들을 알리고 치료의 필요성을 평가하고 치료를 계획하고 결과를 예측하고 보상 방법을 측정하기 위한 환자의 치료와 임상 연구에서 모두 나타난다. 세계적으로 사용되어지고 있는 기능 평가 도구인 FIM으로부터 이 연구는 신체적 측정의 기대되어진 것에 유사한 비율로 기능적 평가 측정들을 구성한다. 노인 재활에서 기능적인 결과의 측정은 중요한 몇 가지 점이 있다. 첫째는 접근에 기초한 기능적인 결과는 치료 목표 설정에 필요하다. 둘째는 도구는 기능적인 향상을 예상하는데 유용해야 한다. 셋째는 기능 평가는 적절한 타당도와 신뢰도와 함께 고려되어져야만 한다. 넷째는 다른 기능적 도구들이 함께 평가되어져야 할 필요가 있다는 것이다. FIM의 목록의 어려운 접들은 손상을 입은 집단에서는 다소 다양하다. 가장 중요한 부분이기 때문에 하나의 운동범위는 요통과 화상을 입은 환자를 제외한 모든 손상을 입은 집단들에게 적용되어 질 수 있다. 기능의 운동과 인지적인 면은 구분되어지는 것이 중요하였고 분리되어져서 치료되어 졌다. 어려운 목록들은 손상을 입은 집단에서 다양하였고, 다양한 손상의 종류의 독특한 영향을 반영하였다. FIM은 기능적인 장애를 측정하기 위해 고안되어진 또 다른 도구이다. 그리고 다른 것들은 의료 재활을 위한 국제적 자료 체계를 만들기 위한 것이다. FIM의 목적은 의료 재활의 결과를 확인하고 장애의 정도의 측정을 포함한다. FIM은 7가지 수준에서 사회적 인지, 의사 소통, 이동, 움직임 (mobility), 소변 관리, 자조 활동을 평가한다. 범위는 총체적 도움의 비율로부터 완전하게 독립적인 것까지의 범위이고 도움, 감독, 도구의 사용의 범위를 고려한다. 27,009의 환자를 조사한 최근 검사 기록들은 FIM이 움직임(motor)과 인지 기능을 평가하는 것이라는 것을 보여준다(Hinemann, 1993). FIM의 저자들은 자료가 프로그램 평가의 시도에서 즉각적으로 적용 할 수 있기를 기대한다. FSI은 어떤 과제의 수행에서 어려움에 관계된 정보를 제공하는 것을 나타내고 과제를 수행하기 위한 환자를 위한 변경된 전략들을 발달시키기 위해 노력하는 임상가들에게 유용할 수 있다. 두 도구 모두는 전통적인 범위들보다 고관절 골절을 동반한 장애의 좀더 정확한 정보를 모으도록 할 수 있다. 고찰된 모든 연구의 결과들은 골절 후에 남아 있는 잔여 장애의 중요한 수준을 강조한다. 골절 전의 보행으로 회복된 사람은 매우 드물었다. 대부분은 기본적인 움직임 혹은 옷입기, 개인 위생에 관계된 활동들에서 의존적이었다. 많은 사람들은 사회에서 활동을 할 수 없었다. 장애의 적절한 측정의 요구는 환자 치료와 기능적인 상태에서 변화를 알고 치료의 요구도를 측정하고 치료를 계획하고 결과를 예상하고 보상 수단을 결정하는 임상적 연구에서 모두 나타난다. 물리치료 분야는 분야의 다른 영역에서 기능적인 결과를 충족시키고 발달시키는 것이 필요하다.

  • The 'fear' in animation has a couple of problems to apply the criteria for identical genre as in movie or literature. First, the mutilation and destruction of one's body and the appearance of monsters and ghosts are not a normal way of expression and could not apply to one genre. Second, the cause of fear comes from the subject of fear which is a reality that is something 'unrealistic' and 'special' and is approachable. This is all possible in a three dimensional world, but animation is not founded on realism. According to this logic, the horror genre in animation or the esthetic experience of animation is not possible. However, many of the powerful images you can see from the horror genre are all created from animation. Therefore, many writers are drawn to the horror in animation and tried to express in many different ways. This study will include the general idea of fear which drives the audience to the felling of fear and terror but we will mainly focus on the three types of fear - ghost story, cannibalism, and madness - and discover the meaning of fear used in animation. Through this process, we anticipate that fear in animation is not just for pure amusement, but will be able to investigate the meaning of fear philosophically even if the hidden side of reality is terrifying.

  • Objective : The PDSQ is a brief and psychometrically strong self-report scale designed to screen for common DSM-IV Axis I disorders in clinical settings. In this study, the K-PDSQ was compared with the M.I.N.I.-Plus (Mini-International Neuropsychiatric Interview-Plus) for diagnostic validity and availability of the K-PDSQ as a part of standardization of the K-PDSQ. Methods : The 640 patients were evaluated with the K-PDSQ and the M.I.N.I.-Plus. Diagnosing with the M.I.N.I.-Plus, the diagnostic correspondence, administering time, sensitivity, specificity, ROC curve, and AUC of the K-PDSQ were evaluated. Results : For the diagnostic correspondence of the K-PDSQ, Cohen's kappa coefficient was .66 between the K-PDSQ and the M.I.N.I.-Plus. The administering time of the K-PDSQ was $18.2{\pm}11.80$ minutes. Both sensitivity and specificity of the K-PDSQ were higher: the mean sensitivity across 10 subscales of K-PDSQ was 86%; the mean specificity was 84%. All AUCs of each subscale were above .80, which were statistically significant. Conclusion : The K-PDSQ is valid and available as a diagnostic screening tool. It will be widely used in clinical settings for screening DSM-IV Axis I diagnosis because of its simplicity and high reliability.

  • In 2022, the Korean Ministry of Environment designated Parthenium hysterophorus as an ecosystem-disturbing plant. The purpose of this study was to present a management plan for P. hysterophorus considering its distribution, morphological, physiological, and ecological characteristics, and to introduce various control techniques. P. hysterophorus is native to Central America and occurs in about 45 countries worldwide. However, in Korea, it only grows in some areas of Tongyeong and Changwon, Gyeongsangnam Province. P. hysterophorus is an annual plant and spreads by seeds, moves between countries in the process of importing and/or exporting agricultural seeds, and spreads by agricultural machinery and vehicles after introduction. P. hysterophorus releases parthenin, an allelochemical that suppresses the occurrence of the surrounding vegetation, from its stems and roots. In addition, P. hysterophorus causes damage to humans and livestock through various allergens. P. hysterophorus can be controlled by physical methods, such as cutting its stems or pulling roots, and by treatment with non-selective herbicides, such as glyphosate. Many biological control research studies have been conducted and, unfortunately, there is no a practical solution so far.

  • $CO_2$ Monitoring, Mitigation and Verification (MMV) is the essential part in the Carbon Capture and Storage (CCS) project in order to assure the storage permanence economically and environmentally. In large-scale CCS projects in the world, the seismic time-lapse survey is a key technology for monitoring the behavior of injected $CO_2$. In this study, we developed a basic process procedure for 3-D seismic baseline data from the Aquistore project, Estevan, Canada. Major target formations of Aquistore CCS project are the Winnipeg and the Deadwood sandstone formations located between 1,800 and 1,900 ms in traveltime. The analysis of trace energy and similarity attributes of seismic data followed by spectral decomposition are carried out for the characterization of $CO_2$ injection zone. High trace energies are concentrated in the northern part of the survey area at 1,800 ms and in the southern part at 1,850 ms in traveltime. The sandstone dominant regions are well recognized with high reflectivity by the trace energy analysis. Similarity attributes show two structural discontinuities trending the NW-SE direction at the target depth. Spectral decomposition of 5, 20 and 40 Hz frequency contents discriminated the successive E-W depositional events at the center of the research area. Additional noise rejection and stratigraphic interpretation on the baseline data followed by applying appropriate imaging technique will be helpful to investigate the differences between baseline data and multi-vintage monitor data.

  • Diversity of the mud flat microbial population in Suncheon Bay was investigated by studying extracellular enzyme activities and 16S rDNA sequences. Four culturable bacterial strains with CMCase, xylanase and protease activities were isolated from the wetland and the mud flat. All the strains produced more xylanase activity than CMCase or protease activity, and the properties of the isolate enzymes from the wetland were similar to those from the mud flat. About 2,000 clones were obtained with the 16S rDNA amplified from the metagenomic DNA isolated from the mud samples. Based on the restriction pattern(s), seventeen clones were selected for base sequence analysis. Of the 17 clones, only 35% (6 clones) were found to be cultured strains and 65% (11 clones) to be uncultured strains. The similarities in the base sequences of the clones ranged from 91.0% to 99.9% with an average similarity of 97.3%. The clones could be divided into 7 groups, Proteobacteria (9 clones, 52.9%), Firmicutes (3 clones, 17.6%), Bacteroidetes (1 clone), Flavobacteria (1 clone), Verrucomicrobia (1 clone), Acidobacteria (1 clone), and Chloroflexi (1 clone). Most of the Proteobacteria clones were gamma Proteobacteria associated with oxidation-reduction of sulfur.
