The development of information and telecommunication has produced new paradigms such as mobile computing, and because of it, mobile commerce has amplified exponentially. From this, circumstance, the real estate brokerage industry has become of new value to users to provide real estate brokerage information through a mobile application, which has expanded the new market. This point of view of study had attempted to suggest that strategic implication and basic information of the manager’s provision of information of real estate brokerage for analyzation that value of the perception factor and perceived value of impact, which has effect on perceived value of real estate brokerage provisioning of information applications. For this, the foundation of a value based Adoption Model and Information Success Model has been analyzed in connection of the quality factor, perceived value, user satisfaction, and continuous use intention. First, the perceived value of real estate brokerage provision of information is influenced positively by the information quality and system quality. Second, perceived value is analyzed by user satisfaction and continuous use intention with an affirmative impact. Third, service quality does not significantly impact the perceived value and user satisfaction, as it does not significantly impact the continuous use intention that is analyzed. This point of view, based on the result, suggests the implication of attempting to increase information quality and system quality, and also enlarges service range.

The animation <Kokuriko-zaka kar> is most recently produced and was released in Korea in 2011`. Miyazaki Hayao planned this amimation, co-wrote the script and it was directed by his son Goro Miyazaki. This animation allows to predict a person who will succeeded to the next generation of Ghbli The animation is composed of three stories. First story is about a struggle between a school that tried to demolish and the student who keep the memories of seniors and to build a new building. The second story is about first love that aroused the suspicion of a brother and a sister. The third story is about a young girl who is waiting for her father. It can be considered to be special as Anime <Kokuriko-zaka kar>, narration of ``only Japan`` that attempted to preserve space of ``parents`` is compared with Korean dramas or narration in novels. Since there are some differences in struggle between <Winter Love Song> of our generation that turn the desire of a heroine that presents a model, saying, “Build my house” into reality of a new house ``for only us`` and narration, this study tried to compare and analyze. Especially, while analyzing the meanings of space in <Kokuriko-zaka kar> such as ``house``, ``club hall``, ``father`` and etc., the reasons why this work is considered as a work for ``only Japan`` and ``only Ghibli``. can be found in the aspects of the subject, characters, and background.

경계와 초월의 시정신 -신경림의 후기시를 중심으로

이경아 ( Kyoung Ah Lee ) 단국대학교 한국문화기술연구소 2013 한국문화기술 Vol.16 No.-

Going back from the latest collection of poems of Sin’s ‘Camel’ in 2008 to ‘Horn’ in 2002 and ‘Silhouette of mother and grandmother’ published in the border of 21 century (1998), his soul of poetry, ‘boundary’ and ‘transcendence’ is analyzed, centering around his latter part of the poems. In addition, in the chapter where his ‘going back’, that is, the overlap of ‘future’ and ‘past’ is checked, looking at the poems in his first collection, ‘Farming danse ‘, it is confirmed that he came back to the root and himself, by going through the experience of community and the world of transcendence beyond reality. Provided the research about Sin Gyung Lim is studied in thecategorization of epic poetry, political poem and folk poetry, this study tries to examine which point did he want to reach, centering around his latter part of the poems. By reading his confession that he finds ‘existence’ in ‘boundary’ and the aspect of behavior, the moment of transcendence is experienced ‘together’ in the echo of lyric and the time of epic along with ‘his walk’. The poetic meaning of ‘boundary’ begins with the question, ‘Where are we?’, including the question, ‘Who am I?’ as someone riding on camel, Personae being weak ens. ‘Camel’ is the weak person, the poet himself, and his walk is his destiny, writing poems. While his first poem began ‘Farming danse’ with dancing and gesture, the walk in his latter poems was changed into slow walking which is safe andspeculative, especially into the walk of camel looking for the desert. Here, camel is the strange existence, the existence of destiny going to his destination, desert, and the existence who will miss the place he left, not feeling strange in the strange landscape. Coming over the unfamiliar scenery, ‘transcendence’ faces from egoto the world. Without seperating his destiny from the destiny of community, ‘transcendence’ of the poet who, introducing ‘we’ the subject to lyric poetry, sings lyrics in the frame of epic poetry, is identified as poetics, poetic method. Turning toward transcendence which aims universality, not closed one, the story becomes confession facing solitude of the subject and ‘voice’, becoming poems of talkingtransferred to readers, that is, poems of confession. Sin’s poetic ethos of boundary and transcendence continuously lies in the time of ‘leaving’.

Henoch-Sch$\ddot{o}$nlein 자반증에서 동반된 급성 부고환염

이경아,박세진,신재일,Lee, Kyoung-Ah,Park, Se-Jin,Shin, Jae-Il 대한소아신장학회 2011 Childhood kidney diseases Vol.15 No.2

Scrotal involvement has been reported from 2% to 38% of males with Henoch-Sch$\ddot{o}$nlein purpura (HSP). It may present before the rash occurs or even long time after it has disappeared. Scrotal involvement of HSP usually results in pain, tenderness, swelling or discoloration of scrotum. Scrotal pain sometimes mimics testicular torsion to various degrees, which can be followed by unnecessary operation. In our 2 cases, one was a 5-year and 11-month-old boy who came to our emergency department due to scrotal pain before the diagnosis of HSP, and the other was a 5-year and 1-month-old boy who came to the outpatient clinic due to scrotal pain after the resolution of HSP about 1 month before the visit. We performed Doppler ultrasonography (USG) to evaluate the acute scrotal pain in the two boys. On Doppler USG, epididymis showed increased blood flow, and testis showed normal blood flow. These findings enabled the diagnosis of acute epididymitis and excluded testicular torsion. Epididymitis was improved by conservative management including shortterm steroid therapy within 5 days. It is important to perform adequate evaluation with tools such as Doppler USG in the early course of acute scrotum of HSP, to avoid unnecessary scrotal exploration. Henoch-Sch$\ddot{o}$nlein 자반증은 2-38%의 남자 환아에서음낭을침범할수있다. 음낭침범은 Henoch-Sch$\ddot{o}$nlein 자반증의 임상 경과 중 어느 시기에든 나타날 수 있으며, 자반이 나타나기 전 혹은 자반이 사라지고 난 후에도 나타날 수 있어 진단이 늦어지거나 오진될 수 있다. 특히 급성 음낭 통증이 동반된 경우 응급 수술이 필요한 고환염전과 감별하는 것이 중요하다. 첫번째 환자는 Henoch-Schonlein 자반증을 진단 받기 전 급성 음낭 통증이 발생하였으며, 두번째 환자는 Henoch-Schonlein 자반증을 치료받고 약 한 달이 경과한 후 급성 음낭 통증이 발생하여 방문하였다. 두 경우 모두 음낭 도플러 초음파 검사를 시행하였고 부고환으로는 증가된 혈류, 고환으로는 정상 혈류를 보여 부고환염을 진단하고 고환염전을 배제할 수 있었으며, 단기간의 스테로이드 치료를 통해 부고환염은 호전되었다. Henoch-Sch$\ddot{o}$nlein 자반증에서 동반된 급성 부고환염은 보존적 치료만을 통해 빠른 속도로 호전될 수 있는 질환이지만, 고환염전으로 오진되거나 이를 배제하지 못하는 경우 불필요한 수술이 시행될 수 있으므로 증상 발생 초기에 도플러 초음파 검사를 시행하는 것이 중요할 것으로 사료된다.

김현욱,이경아,한두정,김천제,백현동,Kim, Hyoun-Wook,Lee, Kyoung-Ah,Han, Doo-Jeong,Kim, Cheon-Jei,Paik, Hyun-Dong 한국축산식품학회 2007 한국축산식품학회지 Vol.27 No.3

본 연구는 육포를 실온조건과 가속조건 하에서 저장하면서 육포의 양념, 포장조건과 환경조건에 따른 육포의 미생물균수의 변화와 이화학적 품질의 변화를 관찰하기 위하여 실시하였다. 육포 저장중의 일반세균수는 실온조건 저장과 가속조건 저장 모두에서 큰 변화가 없었고, 대장균군과 B. cereus는 전 저장기간 동안 검출되지 않았다. 저장기간 동안의 이화학적 특성은 점차 감소하는 경향을 나타내었다. 모든 육포에서의 관능검사는 저장기간이 길어짐에 따라 점차적으로 감소하는 경향을 보였으며, 가속조건에서 전체적인 기호도는 육포의 상품성이 없어지는 시점을 5라고 했을 경우 28일째에 5.54의 값을 나타내었다. 실온조건 저장의 경우 전체적인 기호도는 7.13으로 우수한 관능검사 성적을 나타내었다. 따라서 본 실험의 결과를 통해 새롭게 개발한 한국형 고추장 양념 돈육포는 미생물학적인 안전성이 우수하고, 이화학적 품질과 관능적 품질이 비교적 우수한 육포라고 판단하였다. The aim of this study was to evaluate the microbial safety and quality changes of Korean sliced pork jerky, and to investigate these properties over 90 days and 28 days of storage at room temperature $(25^{\circ}C)$ and elevated temperature $(35^{\circ}C)$. Based on the microbial counts of pork jerky, mesophilic bacteria were detected at 2.50 log CFU/g at day 0. The mesophilic bacterial count did not change significantly for all samples, and coliform bacteria and Bacillus cereus were not detected in any samples during storage at either $25^{\circ}C\;or\;35^{\circ}C$. The following physicochemical qualities were also investigated: TBA value, Aw, and pH. In the case of $25^{\circ}C$ storage, the Aw of Korean sliced pork jerky was 0.72 at day 0, and was reduced to 0.58 after 90 days of storage. The TBA value increased as the storage time increased, and was 0.52 after 90 days of storage. The pH of all samples did not change significantly. In the case of $35^{\circ}C$ storage, the TBA, Aw, and pH values were not significantly different from those obtained during $25^{\circ}C$ storage. In addition, the sensory properties of all samples were not significantly different between storage at the two temperatures. In conclusion, these results suggest Korean sliced pork jerky could be used to study the development of commercial pork jerky.

목적: 본 연구는 대학생을 대상으로 영적안녕, 죽음에 대한 태도 및 호스피스에 대한 인식 정도와 그 관계를 규명하기 위한 것이다. 방법: 대상자는 B 광역시에 소재한 3개 종합대학교에 재학 중인 간호학과를 제외한 대학생 143명이었고, 자료수집 기간은 2014년 9월 1일부터 동년 9월 0일까지였다. 결과: 대학생의 영적안녕 정도는 평균 2.63(척도범위 1~4)으로 중간 정도였고, 죽음에 대한 태도는 2.74(척도범위 1~4)로 중간보다 약간 높은 것으로 나타나 약간 긍정적인 것을 알 수 있었다. 대학생의 호스피스의 인식 정도는 일반적 인식에서 '알고 있다'라고 대답한 학생이 54.5%로 절반수준이었고, 호스피스 관련 교육을 '받은 적 없다'가 93.0%으로 대부분을 차지하였으며, '호스피스를 알고 있다'고 응답한 경우 호스피스를 듣게 된 경로는 '종교기관'이 30명(38.5%)으로 가장 많았다. 호스피스의 목적에 대한 인식 정도는 3.90(척도범위 1~5)로 비교적 높았고, 호스피스의 필요성에 대한 인식 정도는 3.48(척도범위 1~5)로 중간보다 높은 것으로 나타났다. 대학생의 일반적 특성에 따른 호스피스의 목적에 대한 인식 정도는 호스피스인지, 추후 호스피스 수강 의향, 추후 호스피스 자원봉사 의향에 따라 유의한 차이가 있었고, 대학생의 일반적 특성에 따른 호스피스의 필요성에 대한 인식 정도는 부모 생존 여부, 학교생활 만족도, 부모와의 관계, 호스피스 인지, 호스피스 관련교육 수강 유무, 추후 호스피스 수강 의향, 추후 호스피스 자원봉사 의향에 따라 유의한 차이가 있었다. 대학생의 영적안녕과 죽음에 대한 태도(r=0.175, P=0.037), 영적안녕과 호스피스에 대한 인식(r=0.203, P=0.015)은 각각 양의 상관관계였고, 죽음에 대한 태도와 호스피스 인식은 상관관계가 없었다. 결론: 일반대학생의 죽음에 대한 태도와 호스피스에 대한 인식을 증진시키기 위한 죽음 및 호스피스 교육프로그램 개발을 제안한다. Purpose: The purpose of this study is to provide baseline data for the development of an educational program for hospice care for college students. Methods: A survey was conducted at three universities in B city with 143 students from September 5, 2014 through September 26, 2014. The data were analyzed by the SPSS 18 program. This study was approved by IRB. Results: The college students' spiritual well-being was at a medium level. Their attitudes to death were neutral, and perception of hospice care was at a medium level. Most of the participants (93.0%) had no training in hospice care. The participants' awareness of the purpose of hospice care was at a relatively high level. Their awareness of the need for hospice care was at a moderate level. The participants' spiritual well-being and their attitudes to death showed a weak but positive correlation (r=0.179, P=0.030). The relationship between their spiritual well-being and awareness of hospice care were positively correlated (r=0.203, P=0.015). Conclusion: The participants' perception of hospice care was low. Most of them had no experience of hospice care education. Also, the higher the spiritual stability was, the higher the participants' perception of the purpose and the necessity of hospice care was. And their perception of the hospice care varied depending on their family relationship, satisfaction with school life, and cognition of hospice care. Therefore, we need consider these variables to develop a hospice education program to enhance college students' attitudes to death and their perception of hospice care.

During equestrian exercise, communication between riders and horses is very important, and riders’ appropriate signals without any disturbance for the horses’ proper movements are required. Therefore, horses may get different stress depending on the rider’s riding balance, posture, and proficiency. This study was conducted to confirm the difference in the stress of horses between the beginner’s riding and the expert’s riding, additionally, to prove the effectiveness of buffer rein reducing stress even when beginners ride. Average heart rate (HR) was measured for five minutes in stages with a walk, and HR variability (HRV) were measured for three minutes in stages with both rising trot and sitting trot. HRV variables include root mean square of successive differences (RMSSD), standard deviation of normal to normal interval (SDNN), and ratio of low to high frequency components of a continuous series of heartbeats (low-frequency [LF]/high-frequency [HF]). The study involved 6 horses that underwent routine husbandry procedures. The average HR did not show a difference among groups in all exercise stages includes walk, rising trot, and sitting trot. RMSSDs showed lower values for the sitting trot when the beginner rides compared to the expert’s riding (p < 0.05), which means the stress was more increased when beginners ride. On the other hand, when beginners ride using buffer reins, the RMSSD was increased in all exercise stages compared to the case of using regular reins. SDNN was increased when the beginners ride using buffer reins in the rising trot (p < 0.05), which means the stress was more relieved. Ratio of low to high frequency components of a continuous series of heartbeats was not different among groups, but it showed decreased value when beginners use buffer reins rather than regular reins. In this study, it was confirmed that beginners induce more stress on horses than experts during riding exercise and that the use of the buffer reins by beginners more reduces the riding stress of horses compared to when they use regular reins.
