Cough is one of the most common symptom of many respiratory diseases. The Korean Academy of Tuberculosis and Respiratory Diseases organized cough guideline committee and cough guideline was developed by this committee. The purpose of this guideline is to help clinicians to diagnose correctly and treat efficiently patients with cough. In this article, we have stated recommendation and summary of Korean cough guideline. We also provided algorithm for acute, subacute, and chronic cough. For chronic cough, upper airway cough syndrome (UACS), cough variant asthma (CVA), and gastroesophageal reflux disease (GERD) should be considered. If UACS is suspicious, first generation anti-histamine and nasal decongestant can be used empirically. In CVA, inhaled corticosteroid is recommended in order to improve cough. In GERD, proton pump inhibitor is recommended in order to improve cough. Chronic bronchitis, bronchiectasis, bronchiolitis, lung cancer, aspiration, angiotensin converting enzyme inhibitor, habit, psychogenic cough, interstitial lung disease, environmental and occupational factor, tuberculosis, obstructive sleep apnea, peritoneal dialysis, and idiopathic cough can be also considered as cause of chronic cough. Level of evidence for treatment is mostly low. Thus, in this guideline, many recommendations are based on expert opinion. Further study regarding treatment for cough is mandatory.
High salt concentration is one of the most important limit factor on plant growth at a disused saltpan for golf course construction site. The control of salt in soil is definitely required and the monitoring of salt concentration in soil and ground water also required to amend soil physiochemical properties. This research was carried out to monitor the pH and salt concentration changes by the height of ground water. By the physiochemical analysis test, the soil contains a high salt concentration and classified as a slight alkaline clay soil. The height of ground water table changed to 1.3m, 3.3m and 2.8m at dry season(mid-late June, 2005), monsoon season(early-mid July) and after monsoon(late July), respectively. Compare to the average ground level of 2.9m, the ground water was over flooded about OAm at monsoon season. The electrical conductivity(ECe) was measured above $4.0dS{\cdot}m^{-1}$ over all areas and however, some areas showed over $20dS{\cdot}m^{-1}$. During a monsoon season, ECe was lowered to $1.2{\sim}15.0dS{\cdot}m^{-1}$, compared with those of the dry season. Therefore, the interception of the capillary connection between planting layer and ground water which contains high salt concentration should be adapted when golf courses are constructed on disused saltpan. The phytotoxicity caused by salt damage may be controled by the interception of capillary fringe of salt flow to the topsoil profile at the upper layer of the ground water table.
The palatine tonsils which are located in entrance of digestive and upper respiratory tracts are the most important organ in anatomical and functional structures of the pharyngeal lymphatic tissues. As for function of the tonsil, there have been many suspected theories that were included hematopoietic, hormonal, digestive function and production of vitamin, entry of bacteria with other antigenous materials and defence mechanism of which has taken charge by Virchow in 1860 in past. But among these theories, in recently, defence mechanism of the tonsil was strongly accepted immunologically. For the purpose of elucidating immune response of the tonsil, the author observed serum immunoglobulin levels, peripheral total lymphocyte counts and populations of T, B and Null lymphocytes before and after tonsillectomy in 30 cases of patients with chronic tonsillitis and 29 cases of healthy controls. The results obtained were as follows; 1) Serum Ig M level was significantly higher in patient group than in control group but was not significantly different preoperative from postoperative patient group. 2) Population of T-lymphocyte more significantly decreased in patient group than in control group but it was not significantly different preoperative from postoperative patient group. 3) Population of B-lymphocyte more significiantly increased in patient group than in control group but it was not significantly different preoperative from postoperative patient group. On the basis of these results, it may be suggested that tonsil play partially a role in the immune response of human.
A chenier, about 860 m long, 30 to 60 m wide and 0.6∼1.6 m high, occurs on the upper muddy tidal flat in the Gomso bay, western coast of Korea, It consists of medium to fine sands and shells with small amounts of subangular gravels. Vertical sections across the chenier show gently landward dipping stratifications which include small-scale cross-bedded sets. the most probable source of the chenier is considered to be the intertidal sandy sediments. Vibracores taken along a line transversing the tidal flat reveal that the intertidal sand deposits are more than 5 m thick near the low-water line and become thinner toward the chenier. The most sand deposits are undertrain by tidal muds which occur behind the chenier as salt marsh deposits. C-14 age dating suggests that the sand deposits and the chenier are younger than about 1,800 years B.P. The chenier has originated from the intertidal sand shoals at the lower to mid sand flat, and has continuously moved landward. A series of aerial photographs (1967∼1989) reveal that intertidal sand shoals (predecessor of the western part of chenier) on the mid flat have continuously moved landward during the past two decades and ultimately attached to the eastern part of the chenier already anchored at the present position in the late 1960s. Repeated measurements (four times between 1991 and 1992) of morphological changes of the chenier indicate that the eastern two thirds of the chenier, mostly above the mean high water, has rarely moved whereas the western remainder below the mean high water, has moved continuously at a rate of 0.5 m/mo during the last two years (1991∼1992). This displacement rate has been considerably accelerated up to 1.0 m/mo in winter, and during a few days of typhoon in the summer of 1992 the displacement amounted to about 8∼11 m/mo for the entire chenier. these facts suggest that macro-tidal currents, coupled with winter-storm waves and infrequent strong typhoons, should play a major role for the formation and migration of chenier after 1,800 B.P., when the sea level already rose to the present position and thereafter remained constant.
Purpose: This study has been conducted in order to examine the oral health status and dental prostheses status, and the effects of dental prostheses to the oral health related quality of life among the elderly using social welfare centers. Material and methods: For this purpose, the researcher conducted a questionnaire survey and oral examination of 275 samples of old persons using 7 social welfare centers located in Daejeon metropolitan city. The oral health related quality of life was measured by GOHAI (Geriatric Oral Health Assessment Index). Results: 1. The less age and the more education and the more subjective economic status and living with spouse of family status, the higher GOHAI showed. 2. Mean age of first using of removable denture is 62.11 years old and average life cycle of removable denture is 10.76years. 57.5% of study subjects use removable denture and complete denture user of study subjects are 13.8%. 3. In the case that they use fixed prostheses rather than removable ones and in the complete denture they use both sides (upper and lower) rather than single side, showed higher GOHAI. 4. In the case that they showed higher degrees of satisfaction with dental prostheses and can use them always and showed no necessity for new dental prostheses and denture adaptation is good, GOHAI showed higher. Conclusion: In order to improve oral health related quality of life among the elderly who have many missing teeth, it is required to restore their masticatory ability to the normal level by restoring the missing teeth which has lost its function through providing proper dental prostheses.

To know the floristic composition, vortical distribution and community structure of marine benthic algae inhabiting in the intertidal and subtidal zones of Yongil Bay, east coast of Korea, the study has performed using the quadrat method along a transect line from July, 1995 to June, 1996. In this area, a total of 144 species including 2 new red algae to Korea was found: 5 blue-green, 18 green, 20 brown and 101 red algae. The representative species throughout the year were Ulva pertusa, Gelidium amansii and Symphyocladia latiuscula. Dominant species were Sargassum thunbergii in spring, U. pertusa in summer and autumn. In winter, Chondrus ocellatus and Monostroma grevillei occurred dominantly. The standing crop exhibited mean value as $185.8g/m^2$ dry weight. Maximum value was recorded in spring $(267.3g/m^2)$ and minimum was observed in winter $(93.7g/m^2)$. Shannon's species diversity (H') and evenness (J') as maximum value were recorded in spring, whereas minimum values were shown in winter. Vertical distribution, rerognized by cluster analysis based on relative coverage of the species, could be divided into two or three algal groups except spring. In general, green algae (M. grevillei, Capsosiphon fulvescens, U. pefusa, Enteromorpha compressa) and brown algae (Sargassum fulvellum, S. thunbergii) were represented in the upper and middle zone and red algae (G. amansii, C. ocellatus, S. latiuscula, Crateloupia okamurae, Pachymeniopsis eilliptica) in the lower zone. The algal community varied according to season and environmental conditions. Particularly, seasonal variation of vortical distribution seemed to be affected primarily by water temperature. Also seasonal tidal level and tolerance of algal species to desiccation appeared to be associated with it in this area.
To obtain basic information for establishing a pest control strategy for insect pest management system, changes in the population densities of the black-tipped sawfly(Acantholyda posticalis posticalis Matsumura) and damage patterns in tree growth were investigated in national forests in Hoigok-ri, Kapyung-gun, Kyunggi-do, where the pest control measures were taken. The results obtained were as follows ; 1. The larval density in the soil of the forests where the insecticides were applied have been kept below economic threshold for about 7 years. The density was the highest in the middle of slopes and similar to the level of the early stage of the insect outbreak. 2. After the pest control by insecticides, reduction in tree height and diameter growth lasted for 2-3 years in trees defoliated by over 70%. 3. The diameter growth of the trees damaged by black-tipped sawfly recovered faster in upper stem than in the lower. 4. volume growth of the trees defoliated over 70% by the insect decreased for three to four years. The volume loss of trees defoliated by 70% and 90% was 19.6% and 54.0%, respectively. 5. Maintaining the rate of defoliation below 50%, which is the economic threshold, by chemical control measures had an effect of reducing the tree volume loss by $40m^2/ha$ as compared with a stand defoliated by 90%.

The change of species composition and stand structure along altitudinal gradients in different aged stands was studied in five natural stands located each at 400 m, 800 m, 1,000 m, and two at 1,300 m above sea level (asl) in the western part of Mt. Chiri in Korea. Trees larger than 2.5 cm DBH were inventoried in 3 to 8 $20m{\times}20m$ quadrats in each study site. Stand ages were estimated based on the ages of Pinus densiflora Siebold & Zucc. and Abies koreana Wilson, and used to analyze the changes in species composition and stand structure including diameter and height distributions. Species composition was changed along altitudinal gradients as P. densiflora dominated stands at 400 m asl while A. koreana dominated stands at 1,300 m asl. Major species of Quercus also changed along altitudinal gradients as Quercus variabilis Blume at 400 m asl, Quercus serrata Thunb. ex Murray at 800 m asl, and Quercus mongolica Fisch. ex Ledeb. at higher than 1,000 m asl. The diameter distribution did not show significant differences among stands of different altitudes. However, the height distributions of upper crown layers were significantly different among stands at below and above 1,000 m as) (P < 0.0001). Trees taller than 20 m rarely appeared in stands over 1,000 m asl. P. densiflora dominant stands at 400 m asl developed two clumped age groups as one in 30-40 ages and the other around 70 years old. Q. serrata dominant stands at 800 m asl, Q. mongolica dominant stands at 1,300 m asl and A. koreana dominant stands at 1,300 m asl were estimated to be around 30, 70, and over 140 years old after major disturbances, respectively. The diameter distribution with age structure indicated that P. densiflora at 1,300 m asl might be replaced by Q. mongolica, and Q. mongolica might be replaced by A. koreana and Pinus koraiensis later. A. koreana dominant stand seemed to stay its dominance quite long if the large disturbance would be absent.

I. Purpose Brachytherapy is the main component in treatment of patients with uterine cervical cancer. The reproducibility of applicator position in the same patient at repeated treatments was very important for accurate dose delivery. It was aimed to evaluate the change of applicator location between each high dose rate(HDR) brachytherapy insertion in the patients with uterine cervical cancer. II. Materials and Methods From January 1999 to October 2001, total 52 patients were treated with external beam radiotherapy and HDR brachytherapy (Microselectron, Nucletron). During six to seven times of brachytherapy, all patients had three treatment plans. From the orthogonal radiographs, we measured the following variables; height from upper border of pubic bone to os (HPO), distance from sacral promontory to tip of tandem (DST), distance from coccyx to os (DCO), distance from tip of right ovoid to os (DRO), distance from tip of left ovoid to os (DLO), and distance from center of the first tandem source to ovoid (DTO). To evaluate the reproducibility of applicator position, it was calculated the standard deviation of differences between three insertions for the 7 parameters in each patient. III. Results The ranges of standard deviations of interfractional differences for the variables were as follows. 1)HPO : $0{\sim}0.79cm$ 2)DST : $0{\sim}0.9cm$ 3)DCO : $0.06{\sim}0.76cm$ 4)DRO : $0{\sim}0.53cm$ 5)DLO : $0{\sim}0.45cm$ 6) DTO $0{\sim}0.36cm$ IV. Conclusions There was some change in applicator position on repeated implants in our study. But variation of the interfractional differences was minimal; in all parameters, there were less than 1 cm. We are continued to try for reducing the geometric variation between each procedure.
Purpose: This study evaluate clinical findings & management of rhabdomyolysis after strenuous activities in military police recruit. Materials and Methods: This study was carried out from June $1^{st}$, 2004 and May $23^{nd}$, 2005. The study subjects were 13 military police recruit patients who were admitted to our hospital with intractable muscle pain and swelling, and had suspicions of Rhabdomyolysis. The patients were given various blood tests (CPK, CK-MB, AST, BUN/Cr, and Electrolyte) and clinically observed. The patients were all males, and their average age was 20 $(19\sim21)$ years. Seven cases were due to push-up exercises, 5 was due to a soccer game, and 1 was due to riot control activities. The patients complained of swelling and tenderness in various parts of the extremities. Four complained of swelling and tenderness in forearm, 3 in upper arm, 1 in shoulder, and 5 in lower extremity. The diagnosis of rhabdomyolysis was made if the patient complained clinical symptom and had a blood CPK level of above 1,000 IU/L at the time of admission. Patients who took medication or had medical problem were excluded from this study. Bone scans were taken of all patients 4 hours after giving 99mTc-MDP 20mCi intravenously. Treatment was bed rest and fluid therapy. Patients who complained of excessive pain were given splint immobilization. Results: The average hospitalization day for the 13 patients was 20 days ($14\sim42$ days). Excluding one patient who exhibited ARF at time of admission, all patients showed a decrease of blood CPK below 1000 IU/L at an average hospitalization time of 8 days ($2\sim11$ days). The patient with ARF recovered after hemodialysis and fluid therapy. Conclusion: Patients complaining of swelling and severe muscle pain after excessive exercise or training should be suspicious of exercise induced rhabdomyolysis, and should be given blood tests and fluid therapy immediately.
