James S. Gale (1863-1937), a Protestant missionary to Korea (1888~1927), was well-known for his extensive and profound influence on Korean studies and for his translation of the Cloud Dream of Nine (九雲夢), which was the first Korean classical novel translated into English by a Westerner. However, it is not well-known that Gale published a translation of the Great Learning (Daxue, 1924) and arranged for the publication of the Mean of the Doctrine, the Analects and Mencius. This is because it was known that Gale regarded Chinese characters and Confucian scriptures as obstacles to establishing the Christianity during his early period of mission in Korea. This paper examined the change of Gale’s perspective of Chinese characters and the characteristics of Gale’s Daxue. The analysis compares Gale and James Legg in their translations of the Chinese characters ‘命,’ ‘天,’ ‘明’ and ‘君子’ He employed the pure Korean word ‘Hananim’ for ‘God’ from a traditional Korean religion and its Korean etymology, while he rejected the use of Sino-Korean ‘Sangje上帝’, or ‘Chunju天主’ in the Korean Bible. Gale subsequently translated Daxue from a Korean point of view. However, his Korean perspective is mingled with Christianized concepts, which are illustrated in his translation of ‘命’ as ‘God’s command’ ‘天’ as ‘God’ ‘明’ as ‘glory,’ and ‘君子’ as ‘good man’ and ‘godly man.’

This study aims to determine the difference in preferred horticultural plants, horticultural activities, and stress-coping strategies based on Enneagram centers of intelligence in middle-aged women. Data from a convenience sample of 206 middle-aged women were analyzed using IBM SPSS (V. 25.0). The results indicated a statistically significant difference in preferred horticulture plants depending on the Enneagram centers of intelligence. The results also suggested that head- and heart-centered respondents preferred body-centered respondents preferred “foliage plants.” The second most preferred horticultural activities showed no statistically significant difference among the head, heart, and body. However, all three centers showed the strongest preference for “enjoying” among various horticultural activities, and the second most preferred activities differed as “harvesting” among head- and body-centered respondents, and “decorating” among heart-centered respondents. Moreover, a difference in stress-coping strategies was also observed. The head-centered respondents used the “problem-focused” strategy, heart-centered respondents used “hopeful thinking,” and the body-centered respondents used “pursuit of social support.” Thus, these results can be used as baseline data for developing therapeutic horticultural activities while considering the attributes of middle-aged women.

The black cutworm, Agrotis ipsilon (Hufnagel, 1766) is a cosmopolitan pest that poses an economic threat to many crops such as pepper, corn, perilla, etc. A. ipsilon can be mass reared by providing Chinese cabbage, Brassica rapa under 60~70%, 16L:8D and 25±1℃ in laboratory. This study presents the mass rearing methods and the morphological characteristics of the immature stages of A. ipsilon including descriptions of the each immature stages.

The turnip sawfly, Athalia rosae is one of the main pests that damage the leaves of cabbage, radish and other cruciferous crops. The developmental biology and morphological characteristics of the immature stages of Athalia rosae were studied in the laboratory using host plant, Chinese cabbage, Brassica rapa var. glabra. A. rosae can be mass reared in laboratory throughout the year under RH 60~70%, 16L:8D and 25±1℃. This species has six larval stages in the female and five larval stages in the male. The developmental period is about 28~29 days. Ovipositional periods and larval developmental periods were 6, 9 days, respectively. The pupal period was about 14 days. Illustrations and descriptions of the various immature stages and their behaviors are provided.

The objective of this study was to examine the changes in reaction velocity and visual perception between genders participating in driving simulator training. Driving simulator training was performed on 46 adults (male: 20, female: 26) twice a week, 20 minutes per time, 8 times for a month. The results showed that after driving simulator training was significantly more effective for males than females (p<.01). Additionally, the difference in visual perception was also larger in males than in females and it was significantly more effective in males than females (p<.01). This study is expected to contribute to the understanding of differences in reaction velocity and visual perception between adults and handicapped persons of the same gender. The results of this study will also provide a guideline for driving rehabilitation education for handicapped persons in our society and, thereby, help implement driving rehabilitation training systematically.

This study aimed to identify milling characteristics depending on the number of a cutting roller’s air vent and blowing velocity to remove rice bran by the cutting type milling machine which can minimize the conventional milling process. The level of whiteness was found to be 38±0.5 in all the conditions, showing consistent whiteness levels during milling. The rice temperatures turned out to be 15.4 and 14.6oC which were rather low-level under the conditions of the cutting roller with 3 vents and blowing velocities of 35 and 40 m/s respectively. Cracked rice ratio was 2.13% under the conditions of the cutting roller with 3 vents and a blowing velocity of 35 m/s. Broken rice ratio showed the range of 0.762-0.869%, reflecting a low level. Turbidity after milling was decreased, as blowing velocity became faster. Energy consumption for milled rice production was decreased, as blowing velocity became faster. The optimum milling condition for cutting type milling machine depending on air vent number of cutting roller and blowing velocity was found to be 3 vents and 35 m/s.

With the multiple practices of bone graft using different artificial bone regenerative substitutes, the bone graft procedures have been widely performed to increase the bony stabilization of dental implant. Xenogenic bone graft materials have been well developed because of their good biocompatibility and abundant source of bone materials. The present study demonstrated the histological findings from excellent bony remodeling in xenogenic bone graft biopsies compared to those findings in autogenous bone graft. For the graft bone biopsies which were usually done in 5-9 months after graft bone insertion, five types of histological grades including excellent, favorable, partial, degenerative, and poor bony remodeling could be assessed to give prognostic information for dental implant. However, recently the xenograft bone materials have been much improved and produced strong osteogenic effect. Among 239 cases of trephine bur-supported core bone biopsy the excellent bony remodeling was found in 20 cases (13.1%) out of 153 xenogenic bone grafts and in 13 cases (43.3%) out of 30 autogenous bone grafts. They produced abundant new bones on the surface of the graft bones in 5–9 months, and the graft bones were partly resorbed and also surrounded by the repetitive deposition of new bone. The osteophytic new bones showed strong birefringence under polarizing microscope, and were gradually elongated and anastomosed with each other to form trabecular bony networks which became proper stress-baring structures for dental implant. Their marrow stromal tissues were composed of loose connective tissue which was well vascularized but rarely infiltrated with inflammatory cells. The present study compared the histological features of excellent bony remodeling between xenogenic and autogenous bone grafts. Although the ratio of excellent bony remodeling in xenogenic bone graft was still low, 13.1%, the recent advance of xenogeic bone products was remarkable in biological aspect and almost comparable to the autogenous bones. Therefore, it was suggested that the xenogenic bone graft will be applicable to the bone regeneration procedures for dental implant with beneficial output in the near future.

The native human saliva obtained through the centrifugation of whole saliva showed characteristic salivary protein complex (SPC) peaks in gel filtration high performance liquid chromatography (HPLC) using Superose 12 column1,2). In the previous study the SPC peaks in chromatography were explored to know their composition and functions by different detection methods, but still the nature of SPCs was not clearly elucidated so far. In this study the SPC peaks were examined by direct antibody interaction in order to target different antimicrobial and protective proteins distributed in the SPCs via gel filtration HPLC. As the SPC peak shape and migration speed can be changed by antibody binding to specific proteins of SPC, it was found that mucin1 is evenly distribution in all SPCs, while PRPs are more abundant in the late dominant SPC than the early dominant SPC and also in the intermediated SPCs. Most of antimicrobial proteins including lysozyme, LL-37, lactoferrin, β-defensin-1, -2, -3, IgA, mucocidin, and α1-antitrypsin were more abundant in the late dominant SPC than the early dominant SPC, while histatin showed relatively even distribution in all SPCs. Therefore, it was presumed that the late dominant SPC containing abundant antimicrobial and protective proteins could be applied as a biomarker to measure the defensive potential of whole saliva in oral diseases.

c-Fos is known to related to synaptic plasticity and apoptosis in damage from ischemia or external injury. The purpose of this study was to investigate whether needle electrode electrical stimulation(NEES) is effective in increasing the number of c-Fos response cells and c-Fos expression in striatum after global ischemia in rats. There were no treatment and occlusion in the control group, global ischemia(GI) group were no treatment after carotid artery occlusion, and needle electrode electrical stimulation(NEES) group were treated with NEES after GI induced. The number of striatum c-Fos response cells and c-Fos protein expression significantly decreased in the NEES group compared to the GI group after 12, 24, 48 hours. The results of the present study suggest that NEES is ineffective in improving global ischemia in rats and may also be ineffective in the globally ischemic human brain.

Aneurysmal bone cyst (ABC) in maxilla is a rare and benign lesion but shows extensive bony destruction, occasionally accompanied with secondary osseous lesions, i.e., central giant cell granuloma, ossifying fibroma, fibrous dysplasia, etc. As the pathogenesis of ABC has not been clearly defined, ABC is diagnostically challenged due to its variable histological features. A 17-year-old boy showed a huge radiolucent lesion at right anterior maxilla, which was accidentally found in routine dental-radiological examination for orthodontic treatment. He had no medical history of systemic disease, and did not remember any traumatic experience on his right anterior maxilla. The radiolucent lesion involved periapical area from right central incisor to right first premolar, and was clinically diagnosed as odontogenic keratocyst. During surgical operation a cyst-like sac was enucleated with severe hemorrhage. In the histological observation the thick fibrous sac showed no lining epithelium, and its luminal side disclosed multiple aneurysmal spaces which were shrunken and almost obliterated. The fibrous sac itself was hyperplastic with abundant vascular channels, and produced fibromatous thickening associated with ossifying trabecular bones. This fibro-osseous tissue was hamartomatous, which was not directly connected and organized with marrow bone of maxilla. Finally, the present case was diagnosed as secondary type ABC differentially from traumatic bone cyst (TBC), odontogenic cyst, and central reparative granuloma. And it was presumed that the hamartomatous proliferation of fibro-osseous tissue in the cystic sac of ABC could produce the swelling pressure effect in the bone marrow similar to the overgrowth of central giant cell granuloma, ossifying fibroma, fibrous dysplasia, etc., in the secondary type ABC.

본 연구는 사무직 종사자들의 직무스트레스 완화를 위 하여 원예식물 및 활동에 관한 사전 선호도와 직무스트 레스의 연관성을 분석하고자 실시하였다. 원예 활동 경 험과 관련된 사전 선호도 조사에서 원예식물 중 많이 키 워본 식물 및 선호하는 원예식물은 화훼, 채소, 과수 순 으로 조사되었으며 경험해 본 원예활동은 감상하기가 가장 높게 나타났다. 선호하는 원예활동은 키우기, 이용하 기, 감상하기 순으로 조사되었다. 또한, 원예활동 경험에 따른 직무스트레스 측정 결과 식물 가꾸기를 선호하는 사 람의 직무 스트레스가 낮게 나타나는 것으로 조사되었으 며, 채소류에 비해 화훼류를 선호하는 사람이 직무자율 성 결여에 대한 스트레스에서 유의한 차이로 높게 나타 났다. 직무불안정 및 관계갈등 대한 직무스트레스는 식 물이 비교적 유용하다고 응답한 집단의 점수가 낮았다. 이러한 연구결과를 통해 원예활동 프로그램이 직장 내 대 인관계 향상 및 직무스트레스 관리에 적용 가능한 활동 으로 개발할 필요성이 있는 것으로 판단되었다.

In order to know the characteristic roles of salivary protein complex (SPC) the gel-filtration chromatography was performed using the unstimulated and the stimulated whole saliva separately. The first and second dominant SPC peaks were fractionated and analyzed by immunoprecipitation HPLC (IP-HPLC) using antibodies against the essential salivary proteins including α-amylase, mucin-1, proline rich proteins (PRPs), histatin, cystatin, LL-37, lysozyme, lactoferrin, -defensin-1, -2, -3, IgA, transglutaminase 4 (TGase 4), mucocidin, α1-antitrypsin, cathepsin G. In the gel-filtration chromatography the stimulated whole saliva showed much reduced amount of SPCs than the unstimulated whole saliva, but the proportional patterns of both whole saliva were almost similar each other. Through IP-HPLC analysis both of the first and second dominant SPCs were variably positive for the essential salivary proteins, however, α-amylase, mucin-1, PRPs, lysozyme, and cathepsin G were predominant in the first dominant SPC, while cystatin, lactoferrin, β-defensin-1, -2,-3, IgA, mucocidin, TGase 4, and α1-antitrypsin were predominant in the second dominant SPC. And more, the α1-antitrypsin and cathepsin G which were mostly derived from gingival crevicular fluid were also consistently found in the SPCs. These data may suggest that the first dominant SPC, rich in α-amylase, mucin-1, PRPs, lysozyme, and cathepsin G, may play a role in food digestion, protein degradation, and mucosa lubrication, while the second dominant SPC, rich in cystatin, lactoferrin, β-defensin-1, -2, -3, mucocidin, IgA, TGase 4, and α1-antitrypsin, may play a role in the mucosa protection and antimicrobial defense.

Caliber persistent artery (CPA) is a vascular anomaly presenting as a bluish and pulsatile artery in the subepithelial tissue. Although the incidence of CPA was debated, many CPAs occurred in the perioral and facial tissues at which the embryonal strapedial artery networks were distributed. The present study demonstrated a case of CPA occurred in the retromolar buccal mucosa in a 37 years old male. The lesion showed many pinkish granular spots, but was asymptomatic except biting irritation during mastication. It had slowly increased in size up to 20 × 25 mm for 3 years, and recently became hemorrhagic due to the biting injury between left upper and lower second molars. With the fear of oral cancer an incisional biopsy was performed, and followed by histological and immunohistochemical study. Histologically the lesion showed many tortuous artery localized at the submucosa area, and the arterial wall was thick and its lumen was narrowed and shrunken. In the immunochemistry α-SMA was positive for thick smooth muscle layer of artery and arterioles, TGase 2 was weakly positive for the luminal surface of arterial intima, and bFGF was consistently positive for the perivascular fibrous tissue. But PCNA, VEGF, CD31, CMG2, TGF-β1, HSP-70, and 14-3-3 were almost negative for the vascular tissue. Therefore, it was presumed that the lesion was not actively proliferative nor degenerative but still retained its cellular stability and slow growing potential. It was finally diagnosed as CPA differentially from arterio-venous malformation, hemangioma, lymphangioma, and squamous cell carcinoma. The retromolar buccal mucosa CPA is first reported in this study and may present usual clinical findings depending on its size and location. This asymptomatic lesion could be severely hemorrhagic by minor biting injury, therefore, precise differential diagnosis should be made through biopsy, and careful therapy be followed.

A sea urchin was collected from 140 m deep at Gapado which is nearby Moseulpo in Jejudo Island, Korea on 30 June 2010. This specimen was classified as Echinolampas koreana H.L. Clark 1925, belonging to family Echinolampadidae of order Echinolampadoida based on its morphological characteristics. This order and lower categories are newly recorded from Korea. Distinct morphological characters of this species are as follows: test is relatively high. Abactical system has four large genital pores. Periproct is slightly sunken and situated below equator line. Peristome is very small and rather deeply sunken. Tridentate and ophiocephalous pedicellariae are present. Color in alcohol is light purple. These morphological characters are re-described with illustrations.

We investigated the adsorption of Na on graphene and graphene oxide, which are used as anode materials in sodium ion batteries, using density functional theory. The adsorption energy for Na on graphene was -0.507 eV at the hollow sites, implying that adsorption was favorable. In the case of graphene oxide, Na atoms were separately adsorbed on the epoxide and hydroxyl functional groups. The adsorption of Na on graphene oxide-epoxide (adsorption energy of -1.024 eV) was found to be stronger than the adsorption of Na on pristine graphene. However, the adsorption of Na on graphene oxide-hydroxyl resulted in the generation of NaOH as a by-product. Using density of states (DOS) calculations, we found that the DOS of the Na-adsorbed graphene was shifted down more than that of the Na-adsorbed graphene oxide-epoxide. In addition, the intensity of the DOS around the Fermi level for the Na-adsorbed graphene was higher than that for the Na-adsorbed graphene oxide-epoxide.

A 57 years old female received xenogenic bone graft for the extraction socket augmentation of right maxillary molars and for the sinus floor elevation six months ago. The bone graft sites were healed uneventfully and showed marked radiopacity in the postoperative X-ray view. Before dental implant insertion the bone biopsy was made using trephine bur and examined pathologically. The graft bones showed minimum new bone deposition with dysplastic epithelium. The epithelium was proliferative on the surface of graft bones forming epithelial strands and nests, similar to the odontogenic epithelium. The immunohistochemical study was performed using different antisera of odontogenic markers, growth factors, oncogenes, etc. The epithelial cells were strongly positive for pan-keratins, EGF, pAKT, and HSP-70, consistently positive for PCNA, p53, EGFR, 14-3-3, and survivin, slightly positive for ameloblastin, but rarely positive for amelogenin. Particularly the matrix of graft bone was slightly positive for EGF. Taken together, it is presumed that the abnormal epithelium on the graft bones was derived from odontogenic epithelial elements, Malassez epithelial rests, distributed at the periodontal tissue of maxillary molars, and that they might undergo dysplastic proliferation affected by the release of growth factors and osteogenic proteins from the graft bones. It is also suggested that the graft bone substitutes inserted for the dental implant possibly have a potential to induce the proliferation of odontogenic epithelial rests leading to the pathogenesis of odontogenic cysts and tumors.
