Purpose: Because the main drawback of bilateral adrenalectomy is permanent adrenal insufficiency and the subsequent risks of life-long steroid use, adrenal preserving partial adrenalectomy is being accepted as its alternative. The aim of this study is to investigate the indications for bilateral adrenalectomy and to assess the postoperative outcomes and steroid replacement according to operative methods. Methods: From May 1996 through July 2013, a total of 25 patients who underwent bilateral adrenalectomy in our institution were reviewed retrospectively. Surgical outcomes were compared between total and partial adrenalectomy, and postoperative steroid hormone replacement were examined according to the volume of remnant adrenal gland. Results: The median follow-up duration of 25 patients was 55.8 months. The most common indication for bilateral adrenalectomy was bilateral pheochromocytoma (n=16), which was associated with genetic mutation of RET or VHL gene in 11 cases. Cushing's syndrome (n=8) and hyperaldosteronism (n=1) were another indications of bilateral adrenalectomy. Total adrenalectomy was performed in 8 patients and adrenal preserving partial adrenalectomy in 17 patients. Among the 17 patients, only 5 patients needed adrenal hormone replacement and 2 patients had a recurrence at remnant adrenal tissue. Conclusion: Adrenal preserving partial adrenalectomy might be a better option for bilateral adrenal tumor than total adrenalectomy because it can reduce complications associated with adrenal insufficiency and recurrence of the disease is not common.

Although the importance of good conservation of historic sites including ancient royal tombs is well aware, still not much attention has been paid for the facilities and systems to preserve those historic sites, which includes precious artifacts as wall paints and carved works, etc. Even the general understanding about the environment of the underground space of tombs is not satisfactory. In Korea, researchers have recently begun addressing the above issue and are making efforts to develop suitable HVAC(heating, ventilating and air-conditioning) systems for conservation of tombs. An experimental investigation was carried out to study the behavior of the HVAC system installed for a tomb. This tomb resembles in size and shape the original stone built tomb of Baek-je Dynasty, which dates back to 6th Century in southwest part of Korean peninsula. In this study, an HVAC system for a tomb(D×W×H=1.3m×3.0m×1.2m) was installed to maintain sui표 indoor conditions for conservation of tomb. The temperature and humidity inside the tomb were measured different of the setting. Finally, performance of the HVAC system is presented and discussed.

Little is known about the effects of the plane of nutrition on growth performance and meat quality of grow-finish pigs under commercial production conditions. The present study was thus addressed to this virtually unanswered question. One hundred and two barrows and 102 gilts weighing approximately 24 kg were fed phase I and II grower diets with a high, medium, or low plane of nutrition (HP, MP, or LP) to approximately 43 and 70 kg, respectively, in 6 replicates (pens). Subsequently, the HP and MP groups were fed the HP and MP1 finisher diets, respectively, the LP group being fed a second MP (MP2) finisher diet (LP1 group). Moreover, 68 LP-grower-fed barrows and gilts were added to the feeding trial and fed the MP1 and LP finisher diets to approximately 95 kg and thereafter, respectively (LP2 group). All MP diets had the lysine:calorie ratios comparable to the RNC recommendations, with < 18% differences between those of the HP and LP diets. The finisher pigs were reared in 16 pens and slaughtered at approximately 115 kg. The gain:feed ratio, but not average daily gain (ADG), was greater for the HP group than for the MP and LP during the grower phase I whereas during the grower phase II, ADG was greater (p < 0.05) for the HP and LP groups vs. MP. During the finisher phase I, ADG was less for the LP (LP1 + LP2) group vs. HP and MP, with no difference between the HP and MP groups; the gain:feed ratio was less for the LP vs. MP group. Backfat thickness was greater for the LP vs. HP group. The water holding capacity of fresh longissimus dorsi muscle (LM) and the sensory juiciness score for cooked LM were greatest for the LP group, the sensory flavor and tenderness scores being greater for the LP group vs. MP. In conclusion, results suggest that compensatory growth occurred for the LP and MP groups during the grower phase II and finisher phase I, respectively, with fat deposition increased for the LP group and that meat quality could be improved by the use of LP.

Poling is an important process in fabricating PZT ceramic devices such as filters and resonators and activates piezoelectricity to sintered PZT ceramics. Tolerance of the operating frequency of these devices is tightly required in applications. And a factor to attribute the tolerance is the temperature dependence of the resonance frequency of PZT ceramics. In this paper the relationship of poling strength and temperature dependence of resonance frequency of PZT specimens was studied. The Pb(Zr0.53Ti0.47)O₃ ceramics were fabricated and the poling strengths were chosen to be 0.5, 1.5, 2.5 and 3.5 [㎸/㎜]. The dielectric constant of the specimen poled in poling strength 0.5 [㎸/㎜] was less than that of unpoled specimen and the specimen poled in higher electric field had the higher dielectric constant. (002) peak in X-ray diffraction patterns of the specimens increased as poling strength increased. And the change of resonance frequency of the specimens according to the variation of temperature was measured. Resonance frequency of all specimens increased as the temperature increased. The specimen poled in higher electric field had the smaller positive temperature coefficient of resonance frequency. The effect that temperature coefficient of resonance frequency becomes smaller is obtained when Zr mole in PZT composition equation increase. Controlling the poling strength is believed to be a method to adjust the temperature stability of resonance frequency of the PZT ceramic devices.

Isolated ACTH deficiency is a rare disorder, only 50 cases of which have been reported worldwide until nor, and characterized by hypoglycemia, hypotension and hyponatremia. The patient, 56 year-old man, was admitted because of nausea and vomiting. He was diagnosed as hyrerthyroidism and has been treated with antithyroid drug. On admission, serum sodium was 111 mEq/L, potassium 3.7 mEq/L, basal serum cortisol 1.0 g/dl, 24 hr urine free cortisol 5↓ g/day, and basal serum ACTH 10↓pg/ml. Adrenal cortex responded well to ACTH injection, but decreased cortisol response was detected with combined pituitary stimulation test, and ACTH responseses were poor to vasopressin and ovine CRF injection. There were no abnormalities in sellar CT, and hyponatremia was corrected dramatically with hydrocortisone replacement. Here we report a case of isolated ACTH deficiency, which was combined with autoimmune thyroiditis. (J. Kor Soc Endocrinol 4:153~157, 1989)
