Clinical Diagnosis and Treatment of Olfactory Dysfunction

조석현 한양대학교 의과대학 2014 Hanyang Medical Reviews Vol.34 No.3

Olfactory dysfunction is a relatively common disorder that is often under-recognized by both patients and clinicians. It occurs more frequently in older ages and men, and decreases patients’ quality of life, as olfactory dysfunction may affect the emotion and memory functions. Three main causes of olfactory dysfunction are sinonasal diseases, upper respiratory viral infection, and head trauma. Olfactory dysfunction is classified quantitatively (hyposmia and anosmia) and qualitatively (parosmia and phantosmia). From a pathophysiological perspective, olfactory dysfunction is also classified by conductive or sensorineural types. All patients with olfactory dysfunction will need a complete history and physical examination to identify any possible or underlying causes and psychophysical olfactory tests are essential to estimate the residual olfactory function, which is the most important prognostic factor. CT or MRI may be adjunctively used in some indicated cases such as head trauma and neurodegenerative disorders. Functional MRI (fMRI) and psychophysiological tests (olfactory event-related potential, OERP) are also used in the research setting. Compared to rapid progress that has occurred in fields of basic science and diagnostic tools for the therapy of other diseases and disorders, treatments for olfactory loss are still in a state of unmet need. In most olfactory dysfunctions, there has been no well-designed randomized controlled study to justify or prove effective treatment modalities. Therefore, with more attention to the problem and further research we can expect breakthroughs in the treatment of smell loss in the near future.

The aim of this study was to investigate the effect of hazard analysis and critical control point (HACCP) system application on microbial hazard management levels of pork and manufacturing environments. In this study, we compared and analyzed microbial levels in raw meat, finished products, and manufacturing environments (knifes, gloves, and cutting boards) of HACCP and non-HACCP meat markets. In addition, we surveyed the hygiene statuses of HACCP and non-HACCP meat markets. The general bacterial counts in raw meat, finished products, and manufacturing environments were lower in HACCP meat markets than in non-HACCP meat markets. Particularly, non-HACCP meat markets exceeded the Ministry of Food and Drug Safety microbiological recommendation criteria for raw meats (8.7%) and finished products (8.7%). Escherichia coli and coliform counts in raw meat, finished products, and manufacturing environments were also lower in HACCP meat markets than in non-HACCP meat markets. The biological hazard levels of finished products from non-HACCP meat markets were affected by raw meat and manufacturing environment. Moreover, according to questionnaire survey results, personal hygiene, manufacturing environment, and facility standards were lower in non-HACCP meat markets than in HACCP meat markets. Implementation of HACCP at meat markets is expected to minimize food poisoning by reducing the biological hazard levels to provide safe livestock products to consumers.

폐기학습 이론의 한국 행정학에의 도입가능성에 관한 연구: 의사결정과 리더십을 중심으로

조석현,김태윤 한국행정학회 2013 韓國行政學報 Vol.47 No.4

본 연구는 관점, 입장, 초점, 문제의식 등의 차원에서 우리나라 행정학의 일반적 경향성과 폐기학습의 차별성을 드러내어 폐기학습을 우리나라 행정학에 도입할 필요성을 제시하고자 한다. 이를 위하여 분석대상으로 의사결정과 리더십이라는 행정의 주요한 두 가지 영역을 선정하여 분석한 결과, 행정학의 전통적 접근의 주된 문제의식이 사익추구로 인한 비효율성에 초점을 두고 있다면 폐기학습은 내면적으로 형성된 암묵적인 습관기억 및 선택적 지각으로 인한 창조적 기회의 상실에 초점을 두고 있다. 우리나라 행정학이 상대적으로 도외시 했던 암묵지의 사고가 의사결정이나 리더십의 이기적 행위보다 보다 근본적이며 심층적이라는 차원에서 폐기학습의 암묵지가 행정학의 주된 입장인 형식지를 보완하여 활용이 가능하다고 해석할 수 있을 것이다. 또한 과거에 습득한 지식과 사고방식에만 집착하는 폐쇄성의 고리에서 벗어나기 위해서는 조직이나 개인은 낡고 오래된 지식이나 사고를 비움으로서 스스로에 대한 차별화가 가능하다는 해석도 된다. 본 연구는 폐기학습의 문제의식이나 관점, 접근방법 등이 우리나라 행정학을 보완하고 일부는 변경시킬 수있는 가능성이 있다고 결론을 내려, 향후에 폐기학습이 우리나라 행정학에 도입될 필요가 있다고 주장하는 바이다.

Noncalcified benign neoplasms are commonly found on the tongue and are usually located on the lateral borders in the anterior two thirds. But, osteoma of the tongue is very rare and usually seen on the foramen cecum of the tongue. Histologic features are usually those of a well-circumscribed mass of vital mature bone beneath the surface epithelium. Possible pathogenesis of osteoma is the ossification of branchial arch remnant or undescended thyroid gland, and metaplastic formation. Recurrence has not been reported following surgical removal. We report this case with a review of literature. (Korean J Otolaryngol 2006;49:346-8)

방송 클립 동영상 이용과 TV 본방송 시청 간의 관계

조석현,이현지 한국광고홍보학회 2020 한국광고홍보학보 Vol.22 No.3

The purpose of this study is to investigate the correlation between video clip views and TV program ratings. The study is based on the video clip views data(male/female, under 10s/20s/ 30s/40s/50s or higher, drama/entertainment/current affairs, KBS2/MBC/SBS/JTBC/tvN) and ratings data(rating/2049 rating), collected from SMR and Nielsen Korea. The results of the study on the relationship between video clip views and ratings(the next part) are as follows. First, there was a correlation between video clip views and ratings(the next part). Next, there was a correlation between video clip views and ratings(the next part) in all genders and ages. There was a correlation between entertainment video clip views and entertainment ratings(the next part). On the other hand, there was not a correlation between video clip views and ratings(the next part) in drama and current affairs. Finally, there was a correlation between video clip views and ratings(the next part) in all channels. 본 연구에서는 방송 클립 동영상 이용과 TV 본방송 시청과의 관계에 대해 알아보고자 한다. Nielsen과 SMR에서 수집한 실질적 자료를 사용하였고, 방송 클립 동영상 이용자수(남성/여성, 10대 이하/20대/30대/40대/50대 이상, 드라마/예능/시사교양, KBS2/MBC/SBS/JTBC/tvN) 와 TV 본방송 시청률(가구 시청률/2049 시청률)을 중심으로 살펴보았다. 방송 클립 동영상이용이 TV 본방송 시청에 영향을 주는지 알아보기 위해 회 차 간 차이를 두었다. 연구결과는다음과 같다. 우선, 방송 클립 동영상 이용과 TV 본방송 시청 간의 상관관계는 유의미한 것으로 나타났다. 다음으로, 모든 성별과 연령대에서 방송 클립 동영상 이용과 TV 본방송 시청 간의 상관관계는 유의미한 것으로 나타났다. 예능의 방송 클립 동영상 이용과 TV 본방송 시청간 상관관계는 유의미한 것으로 나타났다. 반면, 드라마와 시사교양에서는 상관관계가 없는것으로 나타났다. 마지막으로, 모든 채널에서 방송 클립 동영상 이용과 TV 본방송 시청 간의상관관계는 유의미한 것으로 나타났다

The influence of environmental temperature on the acid base balance of frog(Rana Temporaria Chosenica) blood was investigated at 25℃ all the year round. pH of blood was measured by means of Artrup method and Sigaard- Anderson's nomogram using pH meter(Corning) and tonometer. Buffer value, actual bicarbonate concentration and OH^-/H^+ ratio were calculatedd by the measure buffer line, pH and CO2 gas tension which was used(low CO_2 was 4-5% and high C0_2 was 8-9% balanced with 0_2). Results obtained are as follows: 1. Buffer line was shift to the upper and-right side during winter season and the differences was statistically significant. 2. Buffer value was higher during winter season than summer value and the difference was significan (p<0.001). 3. The actual blood pH was 7.42±0.01 in September and 7.78±0.03 in January. Generally the pH was higher during winter season than that of summer. The difference between two seasons was statistically significant(p<0.05). 4. The blood PCO_2 value has a seasonal changes with low PC0_2 during winter season and the differences were statistically significant. 5. The plasma bicarbonate concentration was 17.00±1.07mM/L in September and the value were decreased with cold weather of 12.33±1.29mM/L in January. Seasonal changes were significantly different(p<0.05). It is concluded from this findings that the acid-base changes of blood in frog were related to the temperature of living habitat and the corresponding changes in the tissue energy store and buffers.

Chondroid syringoma, or mixed tumor of skin is a benign cutaneous neoplasm of sweat gland origin. It is rare in incidence, andmost frequently found at the head and neck area. It is usually present as a slowly growing, painless intradermal or subcutaneousnodule in patients between the ages of 20 and 60 years. Histologically, there are two types, which are tubular, branching luminatype and small, tubular lumina type, and it contains both epithelial and stromal component. The treatment of choice is completelocal excision. We report a case of chondroid syringoma presenting as a nasal columellar mass in a 50 year old woman with abrief review of literature.
