Until 2016, before discussions on the restoration of brackish water of the Nakdong River Estuary started in earnest, the downstream water level was predicted using the data of existing tide level observatories (Busan and Gadeokdo) several kilometers away from the estuary. However, it was not easy to carry out the prediction due to the dif erence in tide level and phase. Therefore, this study was conducted to estimate tide prediction more accurately through tidal harmonic analysis using the measured water level affected by the tides in the offshore waters adjacent to the Nakdong River Estuary. As a research method, the storage status of observation data according to the period and abnormal data were checked at 10-minute intervals in the offshore sea area near the Nakdong River Estuary bank, and the observed and predicted tides were measured using TASK2000 (Tidal Analysis Software Kit) Package, a tidal harmonic analysis program. Regression analysis based on one-to-one comparison showed that the correlation between the two components was high correlation coef icient 0.9334. In predicting the tides for the current year, if possible, more accurate data can be obtained by harmonically analyzing one-year tide observation data from the previous year and performing tide prediction using the obtained harmonic constant. Based on this method, the predicted tide for 2022 was generated and it is being used in the calculation of seawater inflow for the restoration of brackish water of the Nakdong River Estuary.

Since the first pancreatic injury was reported by Traverse in 1827, the pancreatic trauma has been reported with increasing frequency due to high speed automobile accidents and other acts of violences. The morbidity and mortality of the pancreatic injuries reported in the literatures varied 30 to 50 per-cent and 10 to 32 percent respectively. In an effort to improve the results of management of patients with pancreatic injuries, authors analyed the records of twenty-nine patients with acute pancreatic injury and six patients with traumatic pan-creatic pseudocyst, who were treated at the Department of Surgery, College of Medicine, Yonsei University, over the past 7 years. The results were as follows: 1. The sex distribution was 30 males and 5 females, 29 among the were between 16 and 45 years of age. 2. Thirty-four cases were by blunt abdominal trauma and one was by stab injury. 3. The traumatic pseudocyst during the same period was six (17%). 4. The incidence requiring major pancreatic resection was sixteen cases (46%). 5. Associated injuries occurred in 12 cases (34%) and the injuried structures were duodenum, liver, small bowel and kidney in decreasing frequency. 6. The preoperative serum amylase was increased in 19 cases (54%) and it was not significant in the diagnosis of the traumatic pancreatic injuries. 7. The injured site of pancreas was 4 in the head, 6 in the neck, 10 in the body, 6 in the tail and 3 in the body and tail. 8. The operative management was simple drainage (7 cases), simple closure and drainage (6 cases), distal pancreatectomy (13 cases) and pancreaticoduodenectomy (3 cllses). 9. The postoperative complications were present in 8 cases (28%) in 29 acute pancreatic trauma; pan-creatic fistula (5), pseudocyst (4), pancreatic abscess (2) and colocutaneous fistula (1). But there was no mortality.

Purpose: This study aimed to compare expression of human epidermal growth factor receptor (HER) family and insulin-like growth factor- 1 receptor (IGF-1R) before and after targeted therapy in HER-2 positive breast cancers. Methods: Epidermal growth factor receptor (EGFR), HER-3, HER-4, and IGF-1R were immunohistochemically determined using pairwise archives tumor blocks of 28 patients received chemotherapy and HER-2 directed therapy between January 2007 and December 2011. Of them, 5 good responders achieved a pathologic complete response after neoadjuvant therapy and 23 poor responders experienced disease progression or metastasis even HER-2 targeted therapy. Expression of biomarkers was compared using chi-square test. Results: Stage II, III, and IV was 14 (50.0%), 11 (39.3%), and 3 (10.7%) patients, respectively. Hormone receptors-positive tumors were 15 (53.6%) patients and 9 (32.1%) patients received tyrosine kinase inhibitors with or without trastuzumab. Positive expression of initial EGFR, HER-3, HER-4, and IGF-1R was determined in 15 (53.6%), 11 (39.3%), 22 (78.6%), and 14 (50.0%) patients, respectively. Although there was no statistical significance, good responders showed a higher proportion of positive HER-3 expression. Among 23 poor responders, growth factor receptors family expression showed a trend of concordant results, however, unpredictively certain patients demonstrated discordant results between before and after targeted therapy. Conclusion: Unpredicted correlation of growth factor receptors family expression suggested that complex and personalized resistance mechanisms may be involved to HER-2 directed therapy. However, HER-3 expression might be associated with responsiveness to HER-2 targeted therapy. It would be important to develop diagnostic and therapeutic strategies for overcoming resistance to HER-2 targeted therapy.

The present study analyzed the variation factors in inducing a salinity change using the existing observation network in the section between the Nakdong River Estuary Barrage and Changnyeong-Haman Weir, and also examined the seasonal changes in precipitation, salinity, and discharge. Furthermore, this study analyzed the causes of a salinity increase by collecting observational data during a period when abnormal salinity occurred, and further investigated the salinity transfer time in a section of approximately 5.3 km from the Nakdong River Estuary Barrage to Nakdong River Bridge to understand the behavioral characteristics of the salinity moving upstream. The study results would make it possible to control the increase in salinity and block salt water from moving upstream by understanding the salinity variation characteristics according to the discharge amount. This will provide stability in collecting water from various residential, agricultural, and industrial sources through water intake facilities scattered near the Nakdong River Estuary Barrage.
