Consumption of oat-based food is rapidly increasing due to consumer preference for functional foods. Until now, breeding is focused on the development of naked oat for food in Korea. Hulled oats recognized as forage have strong merits for yield and stability in cultivation except milling properties. Lately, advanced milling technology provides an opportunity to use hulled oats for food. Therefore, the processing characteristics of hulled oats are of great importance for food use. This study examined the physicochemical properties and dietary fiber of 9 Korean oat cultivars (4 hulled oats as compared with 5 naked oat cultivars). Findings showed that the color values (i.e. L and W) of hulled oat cultivars in seed and flours are lighter than the naked oats. The protein and ash contents are higher in hulled oats as compared with naked oats. The unsaturated fatty acid (USFA), mainly C18:1, C18:2 were 80~83%. USFA of ‘Daeyang’ (DY, naked) and ‘Jopung’ (JP, hulled) were 82.0 and 81.9% respectively. Total Dietary fiber and Total β-Glucan contents ranged from 13.2 to 20.6% and from 3.4 to 4.1% in oat flours. The ‘DY’ (4.10%, naked), ‘JP’(4.09%, hulled) and Highspeed (4.07%, hulled) showed high levels of β-Glucan contents. Findings of the study will provide useful information in extending the use of hulled oats for food.

The consumption of oats (Avena sativa L.) with high nutritional utility is accelerating due to the increased consumers’ demand for functional foods. In Korea, naked oats are used as food, while covered oats are used for animal feed. However, it is difficult to distinguish naked oats from covered oats when the husk is removed from the grains by a special process. The present study was carried out to investigate experimental methods that would be beneficial in the segregation of different types of oats after husk removal. Grain quality-related biochemical compounds were analyzed in a bid to differentiate the oat dehulling characteristics. In addition, 61 SSR markers were examined for genetic relationship and variety identification of oats using five naked and seven covered oat varieties. Results showed that, the contents of protein, lipid, and β-glucan were not significantly different among the oat varieties and this could not be used as an index for distinguishing oats husk character. However, in the fatty acid composition ratio,, naked oats had a higher ratio of stearic acid (C18:0) and oleic acid (C18:1) than covered oats, and covered oats had a higher ratio of linoleic acid (C18:2) and linoleic acid (C18:3) than naked oats. The assessment of SSR marker genotype revealed that 33 polymorphic bands among 12 oat varieties and 1 variety could be distinguished through the combination of polymorphic markers thus indicating the usability of these markers for variety identification in oats.

Adaptation and quality of naked oat(Avena nuda L.) cultivars in Korea

Byung Gun Park(朴昞槿),Ho Jin Lee(李浩鎭),Kwang Hoe Lee(李光會) 한국육종학회 1995 한국육종학회지 Vol.27 No.4

The naked oat varieties are promising for human diet and for feed of race horse if they adapt well in Korea. We investigated adaptability of oat cultivars, Avena nuda L. obtained from U. K., USA and Canada etc. The naked oats were generally shorter than the Korean hulled oats, therefore, naked oat cultivars were tolerant to lodging. In fall sowing, naked oat cultivars, Pendragon and Kynon showed about 81% and 69% of winter survival rates, respectively, while no hulled oat cultivars survived through the winter. Grain yield was higher in fall sowing than in spring sowing. Grain yields per unit area of Pendragon and Kynon were rather decreased by the polyethylene plastic mulching culture, compared to non mulching culture. Thus, mulching was unnecessary for cultivation of those cultivars in Korea. Grain yield of naked oats were higher than that of hulled oats after removing hull. The contents of crude protein and essential amino acids in naked oat cultivars were higher than that of hulled oat. The content of beta-glucan as an index of dietary fiber amount in the naked oat grain were also higher than that of hulled oat grain. These results indicated that naked oats were superior to hulled oats in aspects such as winter survival rate, kernel yield, and grain quality, and could be introduced successfully in Korea.

개혁주의생명신학에서 본 웨인 에드워드 오오츠(Wayne Edward Oates)의 목회신학과 목회상담학에 관한 연구

양병모 ( Byung Mo Yang ) 개혁주의생명신학회 2011 생명과 말씀 Vol.3 No.-

웨인 오오츠는 남침례교출신의 목사이며, 목회상담가이자 목회상담학자이다. 그는 현대 목회상담학의 선구자 중의 한 사람으로서 많은 임상 경험과 깊은 신학적 통찰을 통하여 목회상담학과 종교심리학, 그리고 기독교 정신의학에 많은 공헌을 하였다. 특별히 그의 교회사역으로서의 목회상담에 대한 강조는 개혁주의생명신학이 추구하는 ``교회를 위한 신학``과 일맥상통한 것으로 그의 목회신학과 목회상담학에 관한 연구가 지니는 의미가 크다 할 수 있다. 어린 시절의 가난으로부터의 자유를 시작으로, 열등감으로부터의 해방, 획일화된 사고로부터의 자유, 외로움으로부터의 자유, 그리고 규격화 된 신학교육의 탈피 등으로 이루어진 그의 인생은 자신의 표현대로 ``자유를 향한 투쟁``으로 설명될 수 있다. 비록 그가 매우 성경적인 태도를 견지하고 있으나 그렇다고 그가 사람들의 영혼의 유익을 위한 다른 학문, 특히 심리학을 무시하지는 않았다. 그는 학제적 연구에 매우 충실하였던 학자였다. 광범위하고도 심도 있는 학문적 배경을 바탕으로 한 그의 목회상담 및 목회신학은 매우 성경적일 뿐만 아니라 나아가서 매우 실천적 신학을 강조하는 개혁주의생명신학의 관점과 일치한다. 목회상담학에 끼친 오오츠의 공헌은 다음과 같다. 첫째, 그는 현대목회상담학을 심리학의 영역이 아닌 신학의 한 영역으로 정립하고 발전시키는데 공헌하였다. 둘째, 그는 현대 목회상담학이 심리학과 목회전문화의 물결에 의해 교회사역의 영역에서 멀어지는 추세를 비판하고 교회사역으로서의 목회상담학의 위치를 새롭게 정립하였다. 셋째, 목회상담학에서의 사회적 관심을 새롭게 조명하였다. 넷째, 그는 자신의 인생을 통하여 신학교육현장에서 임상적 훈련을 통한 신학교육이 교회현장에서 생명을 살리며 실천되는 일에 힘을 기울였다. Wayne E. Oates is a southern baptist pastor, pastoral counselor, and scholar. As a pioneer of modern pastoral counseling movement, Oates, based on many clinical experiences and deep theological reflections, had contributed a lot to the areas of pastoral counseling, psychology of religion, and Christian psychiatry. Especially, the meaningful contribution of this study to ``the reformed life theology`` is Oates` emphasis on the pastoral counseling as a church ministry. Oates describes his whole life as ``the struggle to be free`` such as to be free ``from poverty,`` ``from a feeling of inferiority,`` ``from pack thinking,`` of loneliness,`` ``from factory education,`` and, etc. Even though Oates is very biblically oriented, he has never abandoned his interest in the interdisciplinary study between theology and psychology. Based on his broad and solid academic backgrounds, he has been able to cultivate and develop pastoral counseling and pastoral theology practically as well as biblically. There are several Oates` contribution to pastoral counseling. First, Oates firmly defines pastoral counseling as a part of theology not as of psychology. Second, Oates reestablishes the congregational aspect of pastoral counseling which has been eroded by modern psychology and ministerial specialization. Third, the social emphasis of pastoral counseling has been refocused by Oates. Fourth, throughout his life, Oates has emphasized the practicality of theology with clinical training in theological education settings.

Oat contains a variety of phenolic compounds, including avenanthramides, which are found only in oats. This study was conducted to establish the quantitative analysis of seven phenolic compounds in oat powders and sprouted oat powders and validate an efficient high-performance liquid chromatography (HPLC) method. All calibration curves represented good linearity (R2 ≥ 0.9997) in the concentration range (0.5−50 mg/kg) with LOD and LOQ of 0.01−0.21 and 0.02−0.64 mg/kg, respectively. Intra-day accuracy (%) and precision (%RSD) were 90.7−103.8% and 1.5−4.9%, respectively. Inter-day accuracy (%) and precision (%RSD) were 90.4−107.9% and 2.2−4.8%, respectively. Moreover, relative expanded measurement uncertainty results complied with CODEX guideline. In addition, selected oat and sprouted oat powder extracts showed anti-microbial activities against Escherichia coli O157:H7. These results demonstrated that this HPLC method is suitable for the qualification and quantification of seven phenolic compounds in oat and sprouted oat.

Inspired by many writers, Joyce Carol Oates has rewritten her stories. William Faulkner in particular seems to affect Oates's writing considerably. I think one of Oates's short stories, “The Buck”, is closely related to Faulkner's famous short story, “A Rose for Emily.” At the base of the story rewritten by Oates, some archetypal Faulknerian elements grow into a very different story as Oates's story continues to develop and evolve. In addition, as the layers of Oates's story get thicker, her rewritten story creates various perspectives and delves into human nature. In this paper, I will explore the narrative relationship between Oates's short story “The Buck” and Faulkner's “A Rose for Emily.” I examine how the intertextual relationship between the two works appears as well as the intertextuality with fairy tales. I will also trace the Grotesque elements common to the two works, “The Buck” and “A Rose for Emily.” Oates keeps on evolving her work based on the Grotesque. Since there is no research paper on the relationship between the two works, “The Buck” and “A Rose for Emily,” it is expected that this study will broaden the horizons in the research into Oates's works.

Ji-Lin Dong,Wen-Li Zhang,Juan Lin,Rui-Ling Shen,Jun-Ling Si,Ying Wang 한국식품과학회 2014 Food Science and Biotechnology Vol.23 No.3

Most physiologicalstudies studies of oat beta(β)-glucan have shown positive effects on regulation ofblood glucose and lipid metabolism related to β-glucanmetabolism in the gastrointestinal tract. The effects of oatβ-glucan (OG), oat bran (OB), oat flour (OF), and oatmeal(OM) containing different levels of β-glucan on digestibilityand degradation were investigated in normal mice. Chymeviscosity, the gastric emptying rate, the gastrointestinaltransit rate, the activities of intestinal digestive enzymes,the levels of plasma cholecystokinin (CCK) and motlin(MOT), and degradation of β-glucan in oat products weredetermined. β-glucans from different oat products increasedintestinal chyme viscosity, delayed gastric emptying,promoted enterokinesia, decreased amylase, trypsin, lipase,and Na+, K+-ATPase activities, and promoted secretion ofCCK and MOT, especially for oat derived β-glucan.

Puffing process modifies the chemical and physical properties of the grains. In this study, oats were puffed by subjecting them to pressure of 1.0 and 1.2 MPa, following which the bioactive constituents and antioxidant activities in the oat extracts were investigated. The polyphenol content in puffed oat extracts increased in a pressure-dependent manner (109 and 157 mg gallic acid equivalent/100 g at 1.0 and 1.2 MPa, respectively). In addition, gallic acid was synthesized after puffing (518 μg/g of extract at 1.0 MPa) and was the most abundant phenolic acid in puffed oats. The antioxidant activities, which were determined by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2, 2-azino-bis-3-ethylbenzothiazoline-6- sulphonic acid (ABTS) radical scavenging activities, were improved in oat extracts after puffing (+245 and +184% at 1.2 MPa, respectively). In conclusion, puffing process of oats increased the extractability of polyphenols, including gallic acid, which positively affected its antioxidant activities. These results will provide useful information when using puffed oats for food production.
